Features of light catching

nucifraga, please share where such powerful conclusions come from.

I took a picture of what is written on the box from under the lamp, for full understanding. I use it and I haven't had ANY negative reactions, even minimal ones.

Uw. Yy., Bad Den, omar,
If by "powerful conclusions" is meant the maxim that. that books should be read, I take back my words, or rather clarify: not all books should be read (those that are written by fools, so, those in general should be burned, following the call of the notorious Famusov). But Terskov-Kolomiyets is not one of the last (in every sense of the word), and referring to this book saves a lot of time. A trip to the library is not spent either in terms of time or "renewable resources", if you use the bib-m copier (2-3 p - pages, but not all in a row, namely, those that are needed). At the expense of time-resource - "only one non-renewable" - this is not so at all (And space? And your health? And other stuff?). However, this is already philosophy in a reprehensible sense.

Alas, Comrade nucifraga!
By a powerful conclusion, I meant that I had to go to the library "in scrap metal". Actually, I was wondering-where does such a powerful conclusion come from?

This is not even flood, but so-so, - fludets-fludishko...

I would not recommend measuring its boundaries

Thanks! Now the principle is clear what's going on. The key point - "365 nm" Turns out to be UV-the concept is stretchable, there are lamps with radiation of different wavelengths. It turns out that in your lamp, so to speak, "food" ultraviolet
I admit that I was wrong, and also thank you for the tip, I will have to try such a lamp myself.

On the account...

Dear Nucifraga, unfortunately, it just so happens in our countries, the descendants of the great Motherland, that not all books are present in the library... (not some abstract one, but let's say, for example, the Zaporozhye Regional Scientific Library named after him. Gorky)It just so happened for various reasons that are not always beyond our control. It becomes especially insulting when you come to the library and you don't find the book you went there for, and it's a shame, first of all, for the time you spent (I don't want you to face such a situation, although I think you would understand that you were harsh...). And sometimes it happens that a person works, and his schedule (according to for reasons beyond its control) coincides with the library's work schedule... and getting there for some time (sometimes quite a long time) is not possible...

Therefore, I have a request to you, if you already have this book, state its main postulates, instead of making logical, but not always correct recommendations. This will help you much more significantly!!!

Sincerely,
Mikhail

I catch this in combination with DRV 160 or 400, very satisfied. There is a difference if you use just DRV, as I do, but only in the combination, since in the field from this lamp of light, as from a firefly
If more powerful than 18 W were not so huge in length, I think it would be super, but so, I use one or two 18 W lamps. Try it, I think you won't regret it.
For example, here is a photo of my contruction using this lamp.
[attachmentid()=49865] [attachmentid()=49866]

What do you feed all this construction in the field from?

Forgive me for my skepticism, but it seems to me that if you turn on the DRL 160 in the field, and even more so 250W, then you will catch a lot without a UV lamp.
And if you turn on only UV, then how? Will they fly?
Somewhere above in this topic, professional lamps with batteries of foreign production were discussed. But this, frankly, is a bit expensive. Yes, and delivery / shipment creates unnecessary hassle and costs.
Does anyone know of similar efficiency of ready-made or self-made structures made from more affordable materials?

Do not offer a car or gas generator :-)
Everything should fit in a backpack

I just haven't tried it for one time, honestly. But if you're going to try 18W UV, then stock up on a flashlight, because you can't see a damn thing

Clear
There are full-spectrum lamps that give both visible light and UV.
For example, OSRAM's BIOLUX.
Has anyone tried such lamps?

I tried it. of course, it flies less than on the DRL-250. But under the lamp of black light accumulates typesetter, small, however. But I did not experience much benefit from turning on two lamps together. The DRL still steers. As a person who strives for simplicity, I decided on the usual DRL-250 and NO ADDITIONS! An inappropriate add-on.

in the country and I catch on DRL 250.
But I would like to have a camping option. Specifically for hiking trips.

I took a picture of what is written on the box from under the lamp, for full understanding. I use it and I haven't had ANY negative reactions, even minimal ones.

Especially pleasing is what is written on the label, from which it should be concluded that a person does not see any light from the switched-on lamp - the entire visible range is filtered by a special coating of the bulb! Yes, and 365 nm is still UV. It looks like the lamp manufacturers don't have a technical background. This is so, comments to incompetent manufacturers, but the question is the same: only on it how many times less arrives than only on the DRV-160?

Err! At times. But exactly how many times, I did not calculate the truth, I can not guarantee that the lamp I have is exactly the same.

While there was no generator, I caught on the UVl (bactericidal).In the presence of 220 V -on 30 watt, and in the absence(in the forest, field) - for an 8-watt battery. Years are good, but you need to protect your eyes(when examining the screen, the UVL turned it off, leaving only 18 watts of ordinary daylight). I already wrote about this-(URL#558)

MICHAIL_M'y
Retelling a book is a thankless task. But it is difficult to refrain from mentioning one fact given on the first page of the first chapter. This is a 1965 publication in the German Journal of Applied Entomology. Its author (E. Haeger) for 10 years caught 73 thousand (sic!) copies. There are 547 species of butterflies, i.e. 1 thousand specimens per season (from April to October). He caught the light. The trick is that it was a light of ordinary weaving (incandescent 100 W). You will say ," what makes a Russian feel good, makes a German die, and vice versa. " m. b., I will answer, but not in relation to fishing for light. My grandfather (so as not to be unfounded) in his apple orchard put up such a device on summer moonless nights: a baking tray filled with water stands on a table; a sheet of window glass is vertically fixed above it perpendicular to the short axis of the baking tray; an incandescent lamp is fixed on a bracket near the glass, a longer cord, or even two-through a tee. Turning on the light, my grandfather went to bed (the entomologist sleeps, but the service goes on), and in the morning… In the morning, the baking tray was full of butterflies (they did not need to be killed). And you say UV lamp, UV lamp ...

Yeah, and someone went around the globe on a bicycle, let's now give up the planes. No one disputes that something flies on an ordinary lamp, but in the absence of other light sources. And there are not enough places where it is dark at night now. So we have to improve the materiel. Oh, by the way, and in what region was your grandfather's apple orchard located? And why did he drown so many butterflies? Did you fight pests? And then with wet material, then it's not at all fun to work...

Does anyone know of similar efficiency of ready-made or self-made structures made from more affordable materials?

A lamp specially designed for traps, costs 200 rubles in Moscow, is inserted into any suitable lamp (from 100 rubles).

to Nucifraga

Thank you for the information, uv. Nucifraga, but I can assure you that at home, for an incandescent lamp of 60 Watts, I can catch 10,000 ecz. butterflies, and other insects for the season, but first of all these will be species that live in the nearest district and will not be of particular interest or differ in great species diversity... Yes, it is possible that something interesting will come along, but it will be rather an exception and an accident...
I will not prove the necessity of UV radiation in the process of catching insects in the light, but I will give an example... When I caught at the dacha on an incandescent lamp, the screen mostly sat a scoop-gamma, some trifle (forgive me, fans of micro-lepidoptera) and occasionally came across hawkmoth (maximum 1 per night) (and even then attracted not by the light of the lamp but by profusely blooming flowers)... When I started using the split DRL, hawkmoth, crested bears and ursins began to appear en masse in my training camps... I will keep silent about beetles (in particular water) and caddis flies (for which I wrote a diploma, and never saw them flying into the world)...
Regarding the method used by your esteemed grandfather, it is called the window trap method... This is a wonderful method, and brings quite interesting results... however, the material on lepidoptera can only be used after it by venerable taxonomists... because the wings of butterflies are glued together and the pattern is erased... It gives very good results with a light bulb from a regular pocket flashlight, or even better with a good (more than 20 lumens) LED, in some deserted area... Tested in the Danube region and on the Kola Peninsula.

with uv. Mikhail

here is what is written about light traps in the literature for gardeners... (maybe not a scientific book/article, but very good)

"Light traps for insects

.. Very popular in the 50-70s of the last century, especially among amateur gardeners in small garden plots, was the proposal to use various designs of light traps in pest control. Extensive literature is devoted to the use of light traps in plant protection and mainly in entomology. However, in recent years, this topic is somehow bypassed in the literature for amateur gardeners. Most likely, this is due to a significant increase in prices for electric energy, which is used to power light sources in light traps. Nevertheless, I believe that the author of the letter raised a very important issue related to a very interesting method of controlling harmful insects.
Studies of entomologists have found that a large number of insects of very many species flock to the night light of the lamp. These include garden pests such as fruit moth, moth, unpaired silkworm, moth moth, leafhopper moth and others. The most attractive sources for insects are those with ultraviolet light. Experiments have shown that lamps with such radiation attracted 5-10 and even 20 times more insects than conventional incandescent lamps. Usually, PRK-2 (375 W), SVDSH (100 W) and PRK-7 (1000 W) lamps were used in such experiments. In addition, these experiments have shown that the efficiency of the lamps used increases with increasing power.
Studies were also conducted to assess the impact of external conditions on the effectiveness of attracting insects to night light sources. As it turned out, insects are especially abundant near light sources when the night air temperature is not lower than 12°C, there is no strong wind and sufficient darkness. In cloudy weather and rain, more insects gather than in normal weather. The fog does not interfere with the collection. A very large arrival is observed during the new moon period and, conversely, a very small one-during the full moon period. That is, here the arrival of insects is very closely related to the phases of the moon. Experiments on the time estimation of insect arrivals during the night showed that the maximum occurs at 23 hours, then decreases slightly by 24 hours, after which a sharp decrease occurs...

I found such a light bulb and sent a request for its availability in the store.
How do you think the travel light bulb, maybe someone knows or has met with such already

I asked in the query "is this a full-spectrum UV lamp? Does it require eye protection?"

A response was received:
"Of course not, this is long-wave ultraviolet for decorative
lighting + it can be used to attract insects(lamps for
trap lamps)."


Please note that I did not ask about insects, but they are also available And they cost only 4 bucks apiece.

I will take

they affect the eyes, that's for sure. It is not recommended to look at such lamps.
Insects on such lamps are not bad. I think in combination with drl-super.. especially if you turn it on alternately )
this is about long luminescent ones ))

there is no need to approach the counter with a net

RippeR +1

I'll take it

We are waiting for a detailed report on the test drive

I want to try out a few combinations for the next season:
1. Here is this UV + DRL 250 light bulb
2. This light bulb is UV + DRV 160
3. Here is this light bulb UV + ML 500
And also instead of this UV bulb I will try with two long UV 18W about which it was written above.
Let's see which is better

I want to try out a few combinations for the next season:
1. Here is this UV + DRL 250 light bulb

Do you mean a split DRL?

I don't think. I have never caught on DRL before, always on DRV or ML, so I am a person without practice working with DRL. I'll probably start with non gold

I'll probably start with a non-gold one

What's the point?

not everyone wants to prick )) I am interested in the result with a non-stab))

Which one exactly?
For reptiles full of all sorts of UV lamps, what do you recommend from experience?
I still have to buy lamps, because I keep reptiles
[/quote]

I catch on a lamp not for reptiles, but on this one-URL #762 of this topic, on this page, just above. And I want to try with URL #784 of this topic, but this is already from next season

What's the point?

The meaning is very big. You can desperately collect small beetles near the lamp, looking closely at them, deciding already then-necessary-unnecessary. At the same time, it is not much to worry about your eyes and almost not to peel off the skin of your face.

Ha!
And we are like this


Never peeled off and looked at everything!

so, the fight begins again - to stab, not to stab... Everyone chooses here for themselves. not discussed )

Ha!
And here we are, so
I personally get in the way of extra points. I have a lot of my own people. And I can easily do without a desiccator.

Their own, by the way, also protect well. And how about a small change without an exhauster? It's easy to damage, isn't it?
