Traps - methods and publications. Barber, tree crown, window ones, etc.

it is better to catch it with your hands with a net

Now I want to say a word on the case. Or rather, ask a question.

What kind of trap is used to catch a horse?

I catch them with my hands (preferably with a net, of course). I don't know anything about traps.

That's why I'm asking.
I've chased him several times. I didn't catch it. Too fast

Yes, you will catch more (in May we will have 2 species in the mass on the sand), but I really haven't heard anything about traps for them.

they normally fall into regular glasses.

And I rarely get vinegar. We'll always have to wait longer

do not worry - From vinegar, they cook.

NEW GENERATION CROWN TRAP

1. Emitter


2. Body parts


3. Trap assembly


Operating principle. Open the lid of the radiator, pour a little braga, wood juice, caramel, beer, filthy liquid, in short, anything, up to a dead mouse. If the liquid is filled in, we shove a rag there to increase the evaporation area. We hang the trap. Insects enter through the holes and fall down without touching the bait. We collect insects by shaking them out through the lower neck.

The results will be reported later.

difficult. "Everything brilliant is simple."However, not everything that is simple is brilliant.

The collection takes 15-20 minutes. The perforation is burned with a soldering iron. IMHO, it is not difficult to collect, but it is not suitable for catching on the road, tk takes up a lot of space. Only if you drive directly to the point.

The trap for Latissimus

Just him? Does Latissimus know about this?

Just him? Does Latissimus know about this?

On other water beetles I will use bottles with a smaller throat

About odorous traps: everything goes down the path of excessive complication, everything is much simpler...

Has anyone tried to fill the traps (Barber, window, etc. similar) with winter liquid for the car window washer, as a retainer? I mean the cheapest one.

What's the problem with formalin?

Formalin tans, doesn't it? + it affects the color of some people. I just never used formalin, please enlighten me. I use salt - although there are probably some prerequisites for this as well. As I remember Nimrod, even the material where the fixator was salt, does not accept =). I want to cram Feiri, too, and then they try to evict me from hundreds of other foul-smelling Carabus every summer for a separate residence=) .

I am waiting for detailed descriptions about casting, catching on a tree. For example, I want to try out a spinning reel, but I'm afraid that when I throw it, it will spin up so that the fishing line will get all tangled up.

About the innovation. They specified it exactly - if by car. And I need to fit 6 bottles in my backpack - 1.5 liters each (empty, I just blow them away for this, and we often have empty bottles lying around in the clearings ), 3 bottles - 2 liters (with braga), cups + inventory. I'm for 1.5 liters is so lyrical, but in general, everyone chooses what is more convenient and practical for him. But I'm looking forward to the capultation mechanism

yes, formalin is not a topic at all..
Dubit, disfigures, then it is not possible to straighten ..
salt. vinegar? glycerin?
I tried only salt, for a month in the pre-cold month, for a week in the hottest weather.. I don't know the rest.

salt. vinegar? glycerin?

Salt + vinegar - for soil
And what to use for window do not know, maybe glycerin, after all???

Vitaly, yes, dilute formaldehyde to 2%. If the traps remain without excavation for a long time-I do 4%. And as for the quality of the material from traps with formalin, RippeR knows better - I'm not a collector...

Andrey, we are not talking about collecting the perfect collection material. Adamov previously spoke about accounting and environmental research. For this purpose, formalin is quite suitable. Yes, and if you remove traps in the heat once a week, with other methods of fixing, it is easy to leach the material... There is another advantage - at a concentration of 4% (or higher ) bears don't eat anything that falls into traps.

well, yes.. and I also need to spread beetles

These traps will hang at the level of my head. I won't throw anything in. To catch insects that live exclusively at the level of the very tops, you need to build platforms and a cable car, as entomologists do in tropical forests. Simply throwing so far up the trap can not raise, at least, because the crown of any tree to the top is getting smaller. That is, the lower branches are wider than the upper ones.

I caught a vole

Placed a dead vole in a trap on latissimus

I came to the pond

Catch me Latissimus

What's the argument about? There is such a word in the Bourgeois language-bait-bait
Search for "bait-trap" and you will see a lot of links. In general, traps (or rather, collection methods) are divided into neutral (mowing, Malaise, window traps), where everything falls in a row, and selective or attractive (light, with sweet or not so much bait, pheromone, yellow pan-traps, etc.). What else is there to classify?

  And where and how this trap will be installed is already secondary. There are, however, combined types of traps - the simplest example is when beer or some other brodilov is added to the usual pitfall trap with a retainer, so that the coveted fishing objects climb there more actively.

I had to look for some articles by M. N. Tsurikov. I also went to the ZIN website.
And here's what it turns out, IchMan: a special merit on the personal page of M. N. Tsurikov is recognized as the classification of traps. I quote: "Mikhail Nikolaevich Tsurikov made a very significant contribution to the development of our site and now, undoubtedly, can be considered our colleague, and not just a guest. Especially noteworthy is his original classification of methods and devices for capturing invertebrates. This richly illustrated, hierarchical (with 6 levels of hierarchy), strictly monophyletic system has no analogues and now serves as one of the decorations of our site [emphasis added - Papaver]."

Two D. Marginalis (smooth-shaped females)were trapped on Latissimus
The photo couldn't be taken.
The main thing is that the device works

That's good!!! I set a trap on latissimus for the night and nothing

I return to the effectiveness of Barber's traps.

Observation:
The other day I put 0.5 l glasses on the shore of the Taganrog Bay. I put it with 3.7% formalin and" visors " from the rain (painted fiberboard (150*150mm) with three nails of 70 mm). During the installation process, I caught Demetrias imperialis (Germ., 1824) with my hands. There was no staining at hand, so I threw the beetle into the glass. The beetle was completely free to run around the walls and I barely had time to return it to the glass. Then I quickly poured formalin, but it got out of there almost immediately. In general, I had to stomp to the backpack with a stain. I didn't collect this species with traps before either, although D. monostigma Sam., 1819 fell (also in formalin).
Here is an observation that is not in favor of the Barber trap.

Maybe I'm being silly... And if you smear the sides of the glass with something like vaseline? We used to catch cockroaches in the dorm to feed someone's lizard.

Not stupid. You can try prmazyvat strip on kugu, somewhere near the middle of the glass. However, there are more problems with each trap.

they can be coated in advance, doma

Still an unnecessary complication...

And by volume, who puts what cups???

And by volume, who puts what cups???

0.2 - 0.3 liters-search results.
0.5-0.3 l -for fishing at proven points.

Similarly. But in the end-0.5 liters.
Although I tried once, and even "penicillin bubbles" - caught.
I also put a 5-liter trap - I caught it badly.

Colleagues, please advise us where to find information about traps for the inhabitants of plant litter-litter. I read it somewhere, but I don't remember where. The principle is simple and common in "tropical" entomologists: the litter is collected in a non-luminous cloth bag with a funnel-screen at the end, hung and dried. Spider beetles come out as they dry out. After about a week, the process is completed.. Similar techniques exist for microarthropods. Interested in fabric material, screen size and publications on this topic (preferably from our latitudes).
This is not what is written on the Zinoviev website:"...Recently, various types of eclectors have been increasingly used, among which the Berlesate eclector is the most effective ,as well as extractors (in particular, the Winkler extractor)....". I Googled it,but something is all wrong. Share information about who owns it. With respect.

A good book: Quantitative methods in soil zoology, Moscow: Nauka Publ., 1987.
These methods are available there.

I worked with eclectors for collecting soil microarthropods. I made eclectors from the top of a Novoterskaya water bottle (where the tilt angle is close to the classic requirements) + a piece of mosquito net + a rim made of bottled plastic, from a bottle with a slightly larger diameter (cheap lemonades of 1.5-2 liters).
Not only mites, but also other arthropods, including beetles, fall there.

I haven't tried it with bedding, but the principle is the same, only the volumes are different.

Colleagues!
The other day, we received Yalasa light traps, which were accompanied by completely incomprehensible funnels, such as in the photo. There was only one suggestion as to what they might be used for, but it is unlikely. Perhaps some of you know how to use this contraption in a trap?? We will be grateful for any options
S. Knyazev and V. V. Dubatolov.

It is designed to divert water that gets trapped through the inlet funnel during rain. It is placed at the bottom of the trap container, exactly under the inlet funnel. At the bottom of the watering can should be a little water to create a "water lock" - it does not allow poisons that are heavier than air to leave the trap container.

please tell me, and what is the best way (to dig) to use for installing cups on pebbles, stone scree and other mountains?
