Window traps

When searching on the Web, I found the following page
http://www.ars.usda.gov/Main/site_main.htm...id=10141&page=3
where a wide variety of traps are discussed in detail, and references to the literature on Windowpane Traps go back to 1955 (Chapman, J. A., and J. M. Kinghorn. 1955. Window flight traps for insects. Can. Entomol. 87:46-47.).
Actually, the page turned out to be interesting.

and do you remember Sluchevsky's "... beetles flew, bumping their foreheads ... " - the first hint of traps of this type)))

By the way, about windows: in flower shops/kiosks, you can buy transparent film for bouquets - I don't know what kind of plastic, but it is very transparent (even flies beat their heads during the day) and quite durable. If you take a piece of this film (of any length), attach both edges of the piece to the slats, tie ropes (or strong thread) to the slats at the top and bottom of each end.
This damn thing is stretched and wrapped more tightly with ropes to the trunks of two trees (if the distance between them is less than the length of the stretch, it can easily be reeled in and fixed). You can put anything under this stretch, but I haven't figured out the optimal one yet. I'm still experimenting. So if there are suggestions for rationalization...

Pros: 1-does not break
2-easy to do even in the field
3 - very compact and light when reeled
in 4-stretching of almost any width (I did approx. 2-2. 5 m)

Cons: 1 - if desired, you can still tear
2-it sails quite well, but if you fix it well, it doesn't seem to break.

At the end of July (not the most interesting time, I must say), a sea of interesting animals flew into it for a week.

From what I remember:
Euplectes piceus - several specimens.
2 species of Leiodes (polita and gyllenhali) about a dozen of each somewhere, about the same number of Colenis immuna, one Hydnobius. In the mass of anisotomes - 3 species, but mainly orbicularis. Naturally, half a bucket of Sciodrepoides watsoni + one fumatus.
A couple of Bolboceras armiger. In one day, I picked out a dozen and a half or two Anoplotrupes stercorosus from the trap - apparently, one bad one got in, and all the others followed...
3 species of Eucnemidae (Microrhagus emyi (3), Nematodes filum (many), Hylis procerulus (5-6)), the last 2 were collected for the first time in the region.
There are also Aspidophorus and Lathridius hirtus in the mass.
A couple of Mordellistena neuwaldeggiana, also a nice find. One Hallomenus binotatus, one Phytobaenus amabilis.

So, to whom such beetles are interesting, I advise you to try it. I'm thinking of putting such a thing in the steppe-you never know what's there at all... And it's unlikely that anyone has tried it at all...

I was returning from a fishing trip in April. The road passed through a pine forest. Friends asked what kind of plastic horseradish is hanging on the clearings where logging is being done? He demanded a ride. Two traps hung on poles about 80 meters apart. I've never seen one like this before. Two crossed plates, about a meter high, each blade is about 40 cm wide. at the bottom of the funnel, a simple plastic beer cup(0.5 liters) is attached to it. All connections are made with copper wire. On one of the blades is pasted the factory label(for all idlers)..dyaev) they say, this is a trap for harmful beetles, it does not catch useful ones, and if you see them, do not touch them with your fingers, but go on... There was bug dust in the glass:segments of whiskers, legs, sclerites, wings, elytra, needles, leaves and other tops. As well as a PE bag with blue powder.
Estessno all the leftovers I took. At home, I spread it out on the table. 7 elytra of the goldfish great pine and 1 ndkrl of prionus coriarius.
The second trap contained wet leaves...
It is clear that I did not find anything military... Standard forestry trap. In my Golodran library I found a book: "Reference book. Protection of the forest from pests and diseases." Moscow, VO "Agropromizdat" 1998 (second edition, reprint. Page 93. Chapter 5 "Use of pheromones, hormonal preparations and chemical sterilizers"....
This invention is called barrier traps.
So I decided to do this for myself. And as a lure, I think different substances will do...

Oh, I came across them once at a sawmill. There were 30-40 pieces hanging, just posted. Inside was a pheromone plate of some sort. There were plenty of beetles: staphylinae, dead-eaters, gravediggers, bark beetles, nutcrackers, and a bunch of other things. I made a lot of these traps for myself then, but then I went somewhere else . And I didn't find this pheromone anywhere on sale.

Here is such an outrage But it works

I didn't understand. Where do they fall?

There's another boat-shaped piece on the bottom. With water. There they fall

What about pheromones?And what are the smells of butterflies?and in general, what baits exist and work?

The recipe was shared by Alexander Petrov.
take a laminating film passed through a laminator without paper. 4 sheets are sewn together, holes are made from below and a ring with a package is passed through where the beetles will fall, holes are made from above for hanging. On a long rope, this structure is suspended in the crown of any tree and collects beetles from small to large very well.

In recent days, I have become well acquainted with window traps - a really very good thing, everything falls down! And barbels and goldfinches and euknemids and bark beetles, everything! Recently, I have seen how to bring down species that I have never manually collected.
