What kind of insects do you need traps for???

For butterflies it is necessary.

Interesting site, original. It will be necessary to study it more thoroughly at your leisure.

2 Proctos tell me, please, and what are these yellow plates, about which you wrote in " The Rarest ...". Yellow soil traps in the form of cups saw, and plates? Or a link where you can read it.

search through the Google image search for "yellow pan trap" and you will see a lot of yellow plates and even yellow basins (!) with insects
however, you need to remember that the effect is not 1 plate but a series of at least 50 pieces
In General, the attractiveness of yellow color has been known for a long time and there is such a measure of pest control in the fields how to hang sticky yellow ribbons.

And how do you like this bourgeois method of fishing?

No, the scale is not the same
Specific German entomologist boys are caught like this

By the way, a great site - www.dermestidae.com, I recommend it.

So far, I've only used soil traps made from carabid cups.
By the way, you can also do this on dermoedovs and trupoedovs (I saw it on some site, I don't remember). The same cups, only the corpse or poop is wrapped in gauze, and hung over the cup about 5 centimeters.. I haven't tried it myself yet.. I wanted to, but I didn't get the chance

Does Quito know any traps for barbels?"? Sooo needed!

http://perso.wanadoo.fr/serge.mallet/piegeaE.html - Some barbels fall into the traps described (but that's for Africa).

18 beetle families, including barbels of the genus Dorcadion (D. carinatum, D. holosericium, D. cinerarium, D. pusilum), fall into soil traps (I have), very rarely (accidentally) genus Phitocea.

I've never heard of a specialized barbel trap. Biology is very different in different species. In addition to soil traps, some barbel species are caught in window traps, and there are species that fly to the ground.
And so, it is necessary to collect in habitats - on the flowers of anthophages, mowing in the grass of various stalks, and essno on the feed substrate...

Yes, Barbel Traps-Sweet dreams

Someone here talked about the color of traps... About Barber's traps (soil traps - cans, cups) is there any information about the effect of color on the parameters of the caught material???
And in general, what other soil traps are there, or rather traps for catching herpetobiont invertebrates???

Regarding Barber traps (soil traps - cans, cups), is there any information about the effect of color on the parameters of the caught material???

In the "Zoological Journal" there was an article (unfortunately, I don't remember the year and issue) that provided data on the impact on the attractiveness of certain parameters of Barber traps, in particular, the liquid used to fix the trap and the lid over the trap (presence or absence). I'll try to find this article if necessary.

If you don't mind...
Or at least the year of publication.

I'll try to find this article if necessary.

Today I was in the library and found this article: Feokistov V. F. Efficiency of Barber traps of different types/ / Zoological Journal. 1980, No. 10.

In my opinion, the conclusions are unreliable (the methodology has not been finalized) for such a journal.

The color of traps is unlikely to greatly affect the catchability ( by the number of species), of course. The quantity is affected. I'll bet a minimum of 30. Alekseyev's (Kaluga) article provides very interesting data-a graph of the number of traps and species... Up to 30 - stable growth, and from 30 to 90 - an increase of only 4 species... If necessary - write, I will send you graphs....

The catchability is affected by the contents of the Barber trap. I use vinegar as a fixative, it also saves from mold and attracts beetles. But it is best to catch on beer. Beer is mixed with table salt (5 tablespoons per 1 liter). Very effective. But you have to check the traps more often, because the material spoils much faster than in vinegar.

Beer is mixed with table salt (5 tablespoons per 1 liter). Very effective.

What's the salt for? As a preservative?

Interesting. Salt. But fermented beer works better on carabinieri than vinegar or red wine. The only bad thing is that there are so many forest geotrups stuffed into this beer that you can't even see carabuses.

Salt is used as a preservative. The beer method is good when it is possible to check the traps often, measured once every three days.

And then you can wash their horseradish from the white salt coating.

Yes, barbel traps are sweet dreams

not at all, here is a fragment of a letter from an Italian colleague where he kindly shared the recipe for his "byaki": I prepare the traps with water bottles in plastic of 1.5 or 2 lt. I open a window as higher as possible for about the half of the circonference of the bottle. In the cap a make a small hole where I put a hook made with iron wire and I put on the trees at 5-6 meters with a fishing rod. Inside I use a solution of wine (beer is also good) where I put fruits (banana better) cut in small parts and salt. Salt is very important (I use 1 Kg of salt each 10 liters of wine) because it conserve the insects for long time ( 1 month too) also very small beetles (e.g. Leiopus perfect after 3 weeks) and kill immediately the insects who enter in the bootle. It is very imoportant because the biggest specimens (Cerambyx, Lucanus, Cetonischema etc.) must die quickly otherwise they destroy all the insects. So 10 liters of wine (or beer), 1 Kg of salt, 1 Kg of sugar, and about 3 bananas cut. I use about half liter each trap, anyway if the place is worm and dry you can put more liquid.
The traps don't work for the first week (only few specimens) but after a fermentation they work very very good. I tried last year in Croatia where I was with my family for 7 days and the in traps (the place was perfect) there was only few specimens. The place to put the traps is important too. You must choise sunny and isolated trees (better).
And he caught barbels on it quite successfully. Even I got

Heh-heh, colleague, I caught lukanus and bronzovok for this in Transcarpathia and the Caucasus (pereponov flew just a lot), but not a single barbel arrived in a week (although I did not use salt, but honey infusion instead of sugar...

And then you can wash the white salt coating off their horseradish.

I don't remember that there were any problems with the white coating. Just the material should be washed immediately, and not wait for it to dry out.

And maybe just add alcohol to the beer? As a preservative?

and in my collection there are several good Grammoptera, Purpuricenus gbulicollis and Leioderus collari collected in this way, and according to the results of my colleague's torture, it was found that a week is not enough. It is necessary that the badyaga is well fermented... In any case all claims to P. Rapuzzi

I will definitely try it!

Alcohol at the time of weathering.
I add a little 0.5% formalin . Then not much beetles dubeyut. Yes, the trap can stand for 2 weeks, or even more without signs of rotting entomomaterial. For the purposes of the experiment, I made a mixture of beer with vinegar(7-9%), salt, and formalin . Catchability is 2 times higher than just with formalin 4%.

And maybe just add alcohol to the beer? As a preservative?

With alcohol, of course, you can try it. However, in some cases, alcohol affects the color of some species (especially small things, such as Bembidion).
But as an attractive factor for some bipedal representatives of the local fauna, it can serve as! I had one funny case... I once came to check my beer traps on the Amur River bank (I was very interested in comparing the fauna of anthropogenic biotopes with natural ones). And there sits a certain citizen without a specific place of residence and occupation. Calmly picks out my traps from the sand and without any shadow of embarrassment, throwing out all the material beforehand, absorbs beer (and does not wince!!!). Yes, and the mats are oppressive, about the fact that – " If you don't want to finish it, don't finish it! Nafiga glass of beer in the ground to bury, it OK all sorts of filth falls! Not to myself, not to the people!!!"

Super! I want to try it out, I want to try it out!!

"If you don't want to finish it, don't finish it! Nafiga glass of beer in the ground to bury, it OK all sorts of filth falls! Not to myself, not to the people!!!"

A real joke from the life of an entomologist If you also start adding alcohol to traps, then do not be surprised if over time you notice how a crowd of poorly dressed and unshaven people follow you on excursions, hoping to get a new portion of free "ruff"
As for the traps - at the end of last season, I put about a dozen in one interesting place, and here are the conclusions I made about the fillers:
1. Apple cider vinegar-works great, mostly ground beetles fall, occasionally leaf beetles, weevils, etc. (I deal almost exclusively with beetles).
2. Ordinary (wine) vinegar - practically does not differ in terms of catchability from apple, but in the plus that is noticeably cheaper than the first. I used a 70% vinegar essence diluted with water, and I must say that numerous experiments have shown that there is no connection between the concentration of vinegar and the catchability of the trap.A simple "table" 3-5% vinegar rolls perfectly.
3. Fermented beer (prepared as follows: in half a liter of the cheapest and worst beer-a pinch of dry yeast and a spoonful of sugar, then overnight in a warm place). Advantages of this filler: sharply increased catchability, beetles fall much more, compared to vinegar, including those that did not want to go to vinegar at all (for example, a whole bunch of Ch. staphylea fell into beer, and not a single one fell into vinegar all the time). Disadvantages-if I had to catch drowned mice from a vinegar solution on average once a week,then they went swimming so willingly in fermented beer that almost every trap had such a furry victim of alcohol cravings. Plus, you have to choose beetles from real fly porridge - these diptera can be ten times more than beetles. Yes, and beetles spoil in beer incomparably faster than in vinegar (I was covered with a disgusting, indelible sticky coating of white color )
4. Once it turned out that the traps were simply filled with rainwater for about 2 days: practically nothing was caught in them.

Regarding the use of alcohol: I think that a mixture of vinegar+alcohol+water should not work much worse than beer - after all, ethyl. alcohol and vinegar are both fermentation products, which, as I understand it, attract insects. In the trail. I will definitely try it.

I caught on various "vinegars", both purchased and at home. preparations. (Well, perekislo wine...) On table vinegar (i.e. diluted vinegar) went preim. ground beetles, but not much. On the purchase-Apple and wine cider vinegar were small ground beetles in the set + carbuses, for the night to trap from two to four dozen beetles (all). In addition to carabids-elephants, spangles, staphylines, leaf beetles... and other small things. On the "home" wine vinegar - the same, but less, the concentration is clearly not set. Once I found a vodka bottle. it's full of dung beetles, gravediggers, and ground beetles. Encouraged by this, I set up a few traps with "burnt" vodka-almost nothing. But the homeless people didn't bite either...

So, purchased fruit vinegars are still more effective. Have you noticed the difference between grape and apple? I also once found a cheap port wine rose in the woods, with lots of gravediggers, geotrups, and a handful of 10 pieces, no less than C. glabratus. Interestingly, not a single glabratus came to my traps. There were traps with beer, with fermented beer, with wine, with sour wine, with grape vinegar. I'll try port wine this year!

Like wine is better, but I will not say, because I used different vinegars in different seasons... Here you also need luck, because (checked for sure) if you put it on the "trail" (i.e. where beetles hunt or migrate)"there's a lot of beetles in the trap, and if you're a little off to the side, it's a total bummer. If possible (we stand in one place for several days), we try to move elusive traps, "feeling" for catchy places.

Are there any indirect signs of a bug trail, or is there only one way out-groping at random?

Put this year wine + beer+sugar+vinegar aztskaya semya. A lot of carabuses came, I don't remember the type, geotrups, small ground beetles, spangles, small staphylinids. Generally normal. This is for 1 night. True, with the same ingenuity, I put it in another, bad place - 1 carabus. Near the stream - a lot of 1 type of glitter + some other small thing. On one landing near the river - nebria and a similar size of ground beetles, a few spangles of the same species. In general, the best catch was shown by the trail in the forest.

You are so careful with the mixes-and then accidentally in addition to the mice in the cupboards there will be a crowd of dead homeless people
