Catch on light

There is some information.What's a good one?(I don't know much about them)

The design is as follows:
1. A plastic "bucket" into which insects fall
2. Two test tubes with wool wicks inserted in a bucket to evaporate chloroform
3. A rain roof in the form of a "hat" or "umbrella"
4. Under the roof - a hook on which the DRV lamp is hung.
Such a thing is in the Novosibirsk ISE at my research supervisor, he was given it 20 years ago by a Japanese man. No matter how much I search on the Internet , I only find mosquito traps that are used to create comfort in the fresh air. I asked my Belgian friend - he uses some strange design with a cloth bag; I have a strong suspicion that half of the insects fly past him, and you have to top up the chloroform twice a night
Although if you don't find that Japanese trap in the near future, then you need to get at least some, otherwise you can't write a dissertation without taking it into account...

2Helene:
it seems that almost everything listed above can be built from improvised means . You just need to choose the right lamp for spectral characteristics. And finding a lamp on sale, IMHO, is still easier. Especially if it is possible to power it from 220.

Regarding the "standardness" of the methodology , you will still have to compare your data with your own - so if you use the same homemade product, it will be fine.

I got it There is no trap,but my friend has a lamp,he once caught butterflies on UV.I don't need it right now.What kind of lamp can I specify,I only remember that it is heavy.

2Helene:

Funnily enough, no. When I first saw the ISEZH copy, I immediately copied it so that I could copy it later. But there, on closer inspection, everything turned out to be very difficult. Well, first of all, I didn't specify all the details in the previous message, so as not to create volume (I thought that the specialist would already understand from the words about the plastic bucket and the roof - they would recognize one of the standard structures). And the trick is in the method of connecting the roof and the bucket-there are such blades under the roof around the lamp, connected to the funnel, which enters the hole on the lid of the bucket. That is, insects spin around the lamp, hit the blades and fall into the funnel - and there are already chloroform vapors. There are no lobes or funnels in the European trap. To build such a structure (it is sewn together, and at the end of the funnel there is a plastic ring so that the bucket holds), so that everything fits perfectly, the blades do not touch the lamp - it is almost impossible, at least for me. Well, I'm a mediocre seamstress, a bag for a net-the ceiling, what can you do here...
The second and more serious (in the end, you can sew and ask someone more capable of needlework). These are materials. They are very specific for the Japanese, it turns out. The main thing is that they are not afraid of the heat from the lamp at all. At the same time, they are waterproof (you can work in the rain), light, plastic, and durable. That is, polyethylene and rubberized fabric will not roll.
In general, I came up with the idea that you need to buy your own, no matter how hard it hits your pocket. In the end, the trap served faithfully for 20 years in ISEZH (only now they are also thinking about replacing it), despite the fact that they dragged it on expeditions and did not spare much - they shoved it into a backpack, bending the wire frame, etc.anyone from this forum (let him live forever!)

And finding a lamp on sale, IMHO, is still easier. Especially if it is possible to power it from 220.

I use DRV 150 lamps, they are still easy to buy from us (in Moscow). If the construction markets are closed, as promised , then I don't know. So far, I can even help with the purchase of such lamps, if there is a tension somewhere with them. If you catch on the screen, you can use the DRV 250 (it definitely does not climb into the trap), but you need a special ceramic cartridge for it - it's heavy, you can't hang it on any branch. And the increase in power only leads to the fact that insects settle in a radius of 500 meters around the screen. The only case when a powerful lamp justifies itself is fishing in a populated area, with competing light sources.
I feed the lamp from 220 from the outlet (if available), and in the field - from the generator through a transformer. By the way, the step-up transformer is also infrequent There are still DRV 125 volts, but this is really rare.

I got it There is no trap,but my friend has a lamp,he once caught butterflies on UV.I don't need it right now.What kind of lamp can I specify,I only remember that it is heavy.

A UV lamp is a good thing. There are species that are only attracted to it, they either don't care about bright white light, or they fly in, but they sit too far away, so you won't find them. These are many specific semi-desert scoops. Heavy - probably throttled? I was told yesterday at a meeting by a Ukrainian entomologist that a bank currency detector

I catch from the balcony on the inner bulb with the DRL lamp, and not necessarily as a ballast choke, you can also use a capacitor. It is much more convenient and the efficiency is higher. I also catch on the "economical" fluorescent lamp, which is screwed directly into the cartridge. Its power is 38W. Of course, I haven't heard about any special devices like here. I only know about the "screen", but here it is directly mechanized at the highest level, And the bank currency detector is probably suitable in a remote area where only the stars shine, and even then, it is better when they are behind the clouds..

On the screen, too, we catch-on a lamp with an external bulb, and then the eyes are really a pity, they will also be useful by the way, a friend told me how in student practice during night fishing, the guys demolished the outer flask of the DRL with a net As soon as one inner flask remained-the years went just horse! Butterflies were swarming around like midges, getting in my face... And the students happily caught them for 5 minutes, until the head came and dispersed them. And in the morning, everyone's eyes were red-red... You may have adapted to not looking at the lamp while fishing, but I don't know how to do that.
About mechanization. On the one hand, the trap helps out a lot on expeditions, when you need to conduct night fishing and work during the day, too. And there are species that only fly in the morning twilight - until 5 or 6 in the morning, standing at the screen is absolutely extreme, there will be no work in the afternoon. Well, for the same accounts, too - when manually collecting on the screen, the result will be, to put it mildly, incorrect.

And a bank currency detector is probably suitable in a remote area where only the stars shine, and even better when they are behind the clouds..

P.S. The currency detector has a specific spectrum. Semi-desert scoops are attracted by ULTRAVIOLET light, and the fact that this bulb is dim in visible light does not matter here.

2Helene:
Regarding the "standardness" of the methodology , you will still have to compare your data with your own - so if you use the same homemade product, it will be fine.

Surveys on my topic are conducted not to study some parameter in dynamics (then it is really legitimate to comment on comparing your data with your own), but to "photograph" the current state of the biodiversity of a given biocenosis. That is, what species, what number as a percentage... If the trap doesn't catch well, who knows what's mostly gone? Most likely, those species in which phototaxis is worse expressed: they made two or three circles under the lamp and ran away. So the overall picture will be distorted.
And about the homemade stuff... There is also electricity, plastic, chloroform-everything is nearby... Dumb: "With these pi-er-squares, if only it didn't explode"

Yes, you probably can not adapt to UV, but there is a great way to reduce the impact on the eyes-these are glasses from UV radiation. They are with clear glasses, but the glasses are poorly transparent to UV. In extreme cases, you can order regular glasses to insert "window" glasses into sunglasses, but they delay less.

Well, it is clear that the currency detector is shining UV, and it is not visible, but the power of the detector is very small. Well, just incredibly small, no more than 10-15W in the best case(not for" key chains " but for professional portable ones).

I also decided to try to find out at an amateur level what types of butterflies(nocturnal) live in the vicinity of a certain part of the city, which of them are common, which are rare. But only the first year I catch, only this year I was interested in it
And I try to look at daytime butterflies by all possible biotopes. Night only from the balcony, as I can't go out to catch at night. But still, about 70 types of scoops and approx. There are already 30 species of moth for this year.

to Sealor

I wonder what kind of safety glasses they are? I've only seen sunscreens with a UV filter on sale, but they are all darkened to one degree or another, and the filter power, I think, is not enough: the sun is cold, even in the mountains, and the hard radiation of a UV lamp is another.
The currency detector's power is really low. In addition, I still thought that such a device could not work (shine) for a long time and continuously, because it was not made for this, but that person said that nothing - and the butterflies flew, and the detector remained alive
Regularly and for a long time to catch in the urban environment (to conduct monitoring) is a good thing, you can write a good article. Even if not in a trap, but on the screen (i.e., getting only a list of caught species, without statistics on population density and more or less complete data on the composition of the fauna-this would be super). I was once offered such a topic for my dissertation-on the fauna of urban communities. But I rebelled: life is one, on the Hotz expedition, and here you sit and count the scoop in Moscow! Now I'm doing steppes

Guys! The lamp is definitely a throttle!So is it necessary or not?

Guys! The lamp is definitely a throttle!So is it necessary or not?

Thank you, Dzanat!
If this is a UV lamp, and not a regular DRL, then it will come in handy. In any case, it is worth keeping this matter under control - do not harass the lamp, let it live

In general, there is an idea. MolBiol has a database of biologists with housing, where colleagues arriving on a business trip can fit in. So, let's create a database of EQUIPMENT owners! I mean all sorts of rare and / or expensive things: the same special lamps, traps, generators, as well as laboratory equipment: microscopes, etc. Information about available field equipment can be useful when preparing expeditions (or the owner himself goes, or lends his thing), about laboratory equipment - when working in the office (go to a laboratory where there is an appropriate device and detect at least ticks). Specific conditions for posting information can be discussed (with participants and admins) - to protect the interests of equipment providers

Dzanat, thank you for the links, the article is very interesting and informative. The trap isn't drawn like this, though - it's probably a bug trap.
I think the links should be posted in the "Literature Exchange" section. But I'm not an admin and I can't move anything, and you found them, so copying and uploading from yourself is somehow not the right thing...
If not in scrap, put it there, and?

Helene
Glasses these can be ordered in pharmacies and in large companies, these are transparent glasses specially made to protect against UV. They are usually oriented as "computer". Of course, they do not give the effect of complete comfort, but what can you do, science requires sacrifices If it is so necessary that all the scoops fly from the steppe up to the borders of the horizon, then you can not do without inconvenience.
There is a 1000W DRL with direct UV transmission (phytolamp), that's what you need..

And in Moscow there is a similar job, I found it online, it was quite interesting to read. Well, what can you do, who wants to go to the steppe, and who wants to go to the real forest?

Helene

Something very powerful, it seems... Will they not be seated a kilometer away from the screen, as if using a too powerful visible spectrum lamp?

Well, what can you do, who wants to go to the steppe, and who wants to go to the real forest?

Actually, the Moscow region is not a taiga, this is only from Kharkiv on the map, so it may seem that the border of the forest and forest-steppe does not go straight along the parallel, but in the direction of south-west-north-east. Here, after all, the precipitation regime plays a role, and you never know what else... The south-eastern corner of the Moscow region is already a forest-steppe, and in the Tula and Ryazan regions there is still a lot of such good stuff
I won't pretend to be a scientific cracker devoid of emotions: specialization in the steppes really has a component of just loving the steppes. Although this is not "what is missing", but rather the result of imprinting: all my childhood was spent in the Tula forest-steppe. But the main thing is that forest biocenoses are of little interest to me for purely scientific reasons (although they are very pleasant in themselves, and the insects there are cute).
As for the desire to get into the "real" forest (pseudo-taiga with Christmas trees) - come and show us

Yes, I do not think that it will be very powerful, because where will they sit down, the steppe is all around. If you surround the lamp in a circle with a high screen, then I think the effect will be excellent. Well, in automatic traps, of course, this is not suitable, it will burn the trap and animals.

And I would like the forest not to be coniferous, but deciduous. To a natural deciduous forest bordering the steppe, not the tundra

Here on the steppe and sit down within a kilometer radius-on the grass. Enclosing a screen will not help here. They do not need to sit directly on the lamp, if they are "light" at a distance.

And I would like the forest not to be coniferous, but deciduous. In a natural deciduous forest bordering the steppe, not the tundra

So in the Kharkiv region this should be full! And upland oak forests, and forest belts. Maybe not in the immediate vicinity (although the suburban area is usually actively landscaped). Even in the steppes of the Novosibirsk region and the Altai Territory (and there is Asia, it's dry there!) there are birch pegs-analogous to island oak forests where oak does not grow. And in the Orenburg region there are bayram forests along the gullies. And Ukraine is Europe, the forest-steppe there stretches almost to the Crimea!
When I answered your previous message, I spent about ten minutes scratching my turnips: what kind of forests can be a cool exotic for a Kharkiv resident?

What I don't know, I don't know. I thought that the scoops would fly to the source of maximum brightness, and not sit from afar. Most of them are very mobile. this is a moth that will sit down and sit for itself. And these can easily fly to the light, and then fly away.

And as for the forest and the Kharkiv region, yes, it's definitely full, I looked at the map, but I'm not in the Kharkiv region, but in Mykolaiv! I would have been scratching a melon for an hour if I hadn't eaten it earlier, thinking, how is it that you assumed that I was in the Kharkiv region

And as for the forest and the Kharkiv region, yes, it's definitely full, I looked at the map, but I'm not in the Kharkiv region, but in Mykolaiv! I would have been scratching a melon for an hour if you hadn't eaten it earlier, thinking, how did you assume that I was in the Kharkiv region?

Hm... It will be necessary to go through the entire forum in order to understand in what context someone mentioned Kharkiv, but after all, it was sunk from something. The Mykolaiv region is another matter... Although there should still be trees. In fact, there are a lot of non-moral forests within Ukraine, especially in the western half. Probably, it is quite realistic to find some place like a campsite to get a base - this is if the expedition with a break from civilization (tents, etc.) is extreme for you.
As for the negative perception of the "forest on the border with the tundra", you are clearly wrong. The forest-tundra is actually no less high than the forest-steppe, the fauna there is rich and peculiar, and the places are beautiful. Of course, it is much farther from us than to the steppe - thousands of kilometers , and pseudo-taiga forests are similar to the taiga purely visually (dark coniferous). But some species that are trofically related to the same Christmas tree are found. And we also have" tundras " - these are oligotrophic swamps, and their flora and fauna are much more similar to the real North than between pseudo-taiga forests and taiga.

The design is as follows:
1. A plastic "bucket" into which insects fall
2. Two test tubes with wool wicks inserted in a bucket to evaporate chloroform
3. A rain roof in the form of a "hat" or "umbrella"
4. Under the roof - a hook on which the DRV lamp is hung.

I have a light trap of a similar design. But I can't share it - I use it all the time myself. It was not so difficult to make it based on the drawing (my supervisor gave it to me, and he, in turn, borrowed the idea from the Latvians). I have it sewn from parachute silk (but you can also use tarpaulin), and the "umbrella" is made of greenhouse film. As a light source, I use 2 energy-saving lamps. Recently, there was an idea to add a light sensor to the trap so that you don't have to turn it on or off yourself, but come to the dacha once every 5 days, choose a catch and leave again. But energy-saving lamps can not be used with this sensor. So I bought some kind of lamp on the market today, like a 250-watt DRV made in Poland. I'll try pohimichit... As a fixative, I use ethyl acetate and dichlorvos.

"But energy-saving lamps cannot be used with this sensor."
Why is that?? Is it chtobli from the fact that the boxes say something similar? I have similar lamps working with timers and nothing. What difference does it make if you turn it off, or if it's a timer or photo sensor relay?
You can't turn it on or off often, that's for sure.
It is not desirable if the photo sensor triac connection, and then, with the correct selection of the circuit-no problemm!
And in such cases, it is better to use a multifunctional timer, set a program for a week, like 21.00 ON 6.00 OFF and works fine.

About the parachute silk. I have previously made a clarification about the possibility of making a homemade product:

Well, first of all, I didn't specify all the details in the previous message, so as not to create volume (I thought that the specialist would already understand from the words about the plastic bucket and the roof - they would recognize one of the standard structures). And the trick is in the method of connecting the roof and the bucket-there are such blades under the roof around the lamp, connected to the funnel, which enters the hole on the lid of the bucket. That is, insects spin around the lamp, hit the blades and fall into the funnel - and there are already chloroform vapors.

If you do this (with the blades), these very blades will be very close to the lamp. Ignite after all! At least, I had a case when the wind pressed the DRV to the screen, and it burned the screen just like that, no worse than an iron. The Japanese have some special material, they are not afraid of the heat... Although, maybe I'm a reinsurer about TB... But I wouldn't leave the trap turned on at the dacha for a working week
And energy-saving lamps in this context are probably just preferable, because they heat up incomparably less than the DRV, and the voltage there is only 12 V. Only the spectrum is a little different: we specially checked that they fly better on the DRV.

Hello everyone
A light trap is fine, of course, but only if you check it every hour.
There are a lot of disadvantages: insects are damaged, fly somewhere by, if in the morning you do not have time to check the light trap before the birds, then the wings and antennae will remain.

But the 250-watt DRL is the best, only you need to carefully break the flask and connect the throttle. And the DRV has a choke inside it, so if you split the bulb, you can kill the lamp. In general, nocturnal insects are most attracted to the ultraviolet light of a 250-watt lamp. All these energy-saving and other lamps do not work. Even in the wild, where there are no lanterns nearby, the effect of them is very small

Good day to you too!

There are a lot of disadvantages: insects are damaged, fly somewhere by,

To avoid insect damage, ISE has know-how (I give it to everyone!).
In the bucket, you should put a crumpled newspaper as a large, very large accordion. It sounds ridiculous, but it helps
Checking the trap every hour is really useful - but not because something can happen, but because there are flightless insects that do not crawl into the trap themselves, but sit under it. Even butterflies can do this on cold nights.

 
if you don't have time to check the light trap before the birds arrive in the morning, you will still have wings and antennae.

But I don't understand How the birds will get there if there is a tightly closed plastic container?! Just what is good is that there will be nothing for the fees: everything is closed, even from the rain the hat protects well...

But the 250-watt DRL is the best, only you need to carefully break the flask and connect the throttle. And the DRV has a choke inside it, so if you split the bulb, you can kill the lamp.

Yes, if you need a bare UV part, then the DRV is not suitable. IMHO, if you beat the flask at the DRV, it is not "possible to kill", but you will kill for sure...

All these energy-saving and other lamps do not work. Even in the wild, where there are no lanterns nearby, the effect of them is very small

Yes, apparently, the spectrum of halogen bulbs is not the same.

Despite the differences, thank you for reviving the topic

The DRL-250 has a heavy throttle, but then the DRL-125 is better-it also has a smaller base.
A capacitor instead of a choke is not recommended: it is dangerous and the lamp life drops sharply. For a broken DRL, you need to come up with a grid so that insects don't get burned, and gas welder's glasses so that your eyes don't get burned :-). And for energy-saving lamps, the UV component is really small. A camping version of the light trap is probably easier to make from a Chinese flashlight with daylight lamps (such as our LB-4 -6 -8), and replace these lamps with LUFT from the currency detector or bactericidal DRB (they will have a harder spectrum)/ Here people are already making traps out of LEDs:
http://insect-hunter.narod.ru/permob.htm

Especially for Helen:
Thank you for your feedback. I used a light trap, either German, or some other, I don't remember (in short, from the West. And it was very well penetrated by all sorts of sparrows and other birds.
Still, I'm not a fan of traps. Even with newspaper and sliced strips of paper, moths remain severely damaged. And I want the material to be clean and not frayed.

If you have had a negative experience with an unsuccessful design or unsuccessful technology (for example, when the accordion is not laid, they spare chloroform or pour ethyl acetate into the trap), then there is a negative attitude to this method of fishing in principle. This is familiar to me, it is treated again by personal experience, but I was also fundamentally against mechanization of the collection, until I worked with the Isezhevskaya trap myself. In fact, if everything is done correctly, the percentage of dead butterflies corresponds to what is found in nature. That is, nothing else beats, but already broken ones fly in. Where butterflies are severely damaged due to local conditions (for example, near scree-scoops like to poke between rocks and knock down their backs), it may seem that the trap is to blame. But if you put a screen in such a place , you can make sure that a lot of broken data is flying. If you need collectible material, it is better to go to the screen (you can choose).
And as for the European traps... I already mentioned them at the beginning of the topic. I immediately assumed that half of the insects there were flying past. As for Birdalone, it never occurred to me... In general, definitely the trap should be Japanese (see above)! "Light - from the East" ...

why some kind of light trap????? so subjective are the samples and the mass murder of your favorite boogers, and the kilograms of bedbugs, staphylinchikov, many others you will ruin without even trying to save and determine. What valuable conclusions have been drawn from hundreds-hundreds of murderous studies with Barber glasses? indication? well, who is indicating these works? everyone develops their own gitics. AND IF THIS IS A YUNNATIAN OR 1ST STUDY WORK WITH A LIGHT TRAP, IT IS BETTER TO FIND GORNOSTAEV'S WORK IN THE WORKS OF V. E. O.

I am, however, interested in MALAISE TRAPS-TRAPS of MALAISE ("ILLNESS" - literally.translation, which is also symbolic) - but I did not and will not have any mass alcohol tombs there, even if it is "not scientific". I WOULD LIKE TO SHARE THE EXACT PATTERNS OF MALEZ TRAPS - WHO KNOWS (on tokmirov@rambler.ru), because you have to do it by eye. And researchers have barely begun to study the phenology of, for example, groups of insects caught by it. Or define Anthomyiidae, Proctotrupidae etc.

For example, M. Tsurikov, a zhivolovushek enthusiast, works in Galichya Gora. He has more than 200 different traps, mostly based on tophi. Learn from the experience!

Well, maybe someone will be able to coordinate the ethics and necrophilic tendencies of mass procurement (at least merchants will sell it sooner or later), and not lose the truly deep meaning of scientific research, but with a violation of ethics, the truth will not be revealed.

In general, you are right - the most commonly used traps with retainers are extremely imperfect, but after the collapse of the USSR, primary entomological education fell into extreme decline, at first everyone uses old books, and there is no smell of selective traps.
On the other hand, sometimes there is a time for the whole night when you can only do attractive traditional light traps without retainers (in fact, using these traps on the road is much more profitable than using traps with retainers for many reasons), so not everything is as bad as you think.

why some kind of light trap?????
...

Wahhh... well, the animal rights activists have visited us! Just don't hit me in the face with a cake or throw paint on me!
I don't understand why in a professional topic so famously deal with people and their work ("yunnat work", etc.)?..
Essno, every living creature is pitiful - and insects too. But the objective reality is this:
1. It is impossible to carry out the same indication or accounting of entomofauna by non-lethal methods, while maintaining scientific correctness. Because it is impossible to reliably identify most species live in the field. And because it is impossible to recalculate on the screen. These are not Ussuri tigers, which animal experts count by their tracks, etc
. 2. There is a significant difference between the butterfly population and the zebra population. Given the fecundity, rapid generational change, and percentage of natural waste that exists in insects, even "mass murder" does not cause real harm to the population. Exceptions are very rare (and not generally recognized). I understand that this does not convince the principled opponent of "necrophilia", but it is true.
3. Thoughtlessly throwing out non-core groups is really a matter of scientific ethics (or rather, its absence). I don't think that the level of the forum gives grounds to attribute such a position to its participants a priori.

And the question about the trap of Malez (patterns) - I support. Really very necessary thing and it is also difficult to get. If anyone knows-I suggest (except for the message To.K. by mail) to post on the forum

hello everyone!
about the Malez trap Gooogle gave me 250 photos and patterns like this page http://bughunter.tamu.edu/trapping.htm etc.

Most likely, this is a modification of the" Window "trap (Window trap), only made of "gas" or polyethylene. Meaning - at dusk, an insect stumbles and falls into a container with a lock.

yes, I understood (Nikitsky drew a window for me), but this particular fenka intrigued me. somehow it's not clear. I can reproduce this thing, but the principle of fastening (installation-stretching) is hidden by a riddle

The Malaise trap is not the same as the window trap. "Malezu" is hung in the daytime somewhere-a thread on a bush, it entangles eardrums and flies... The most necessary thing for those who need these groups.
But about the links... I was hoping I could buy a trap somewhere, but no... Although I found an English site, it seems that everything is clear there. Museum Shop - just the address of the souvenir shop attached to the museum.

Clarification: insects do not get entangled, but drown in a trap jar with alcohol, unable to fight positive geo and heliotropism.
It is impossible to buy from us. Morpho traps are of a simplified type, low, single-colored, and what is absolutely unacceptable, without the use of sealed cans! It's just a sleeve with a cuff... I was pretty fucked up when I saw them. American models are very good, but insanely expensive, from $ 150 to $ 200. I use them only out of courtesy of my Western colleagues. And most importantly, THEY are WILLINGLY STOLEN by local residents (in my case, in Lesotho, savages cut ropes and stole metal poles)... I'm afraid that says it all..

By the way, in the pictures from the site http://bughunter.tamu.edu specialized horsefly traps are shown. The idea with the black ball is original, I recall that in Russian literature it was suggested to put together a plywood cow, paint it black and stand next to the net. Maybe it's a joke, though... But there were cone traps.
