Insects fumigating

I first used the stain this year...and I had a problem with the cows with cotton wool sticking to them and I started using a napkin instead of cotton wool...
And another important question is where to get ethyl acetate in Kharkiv ,because there are no entomological stores in Ukraine??????????????????????

Uv. Liparus, first of all, ethyl A cetate (ethyl ether of acetic acid)is available in entomoestores You are unlikely to find it, it is easier to buy it in specialized stores of laboratory equipment and chemical reagents. And secondly, you can Google and find the following: http://www.labteh.kh.ua/Xim/Organika.html By the way, I looked at the travel map and found out that you have a metro in Kharkiv. As they say, respect and respect.

And there is a lot of information in the separate topic " Where to buy ethyl acetate?" (if I remember exactly its name)

How to inject with ammonia? One person suggested that you squeeze a drop on the end of the needle so that it hangs and insert it into the butterfly's chest. Question: a drop will just spread out and that's it. Or enter and then push the plunger?

Insert and push the plunger. It's easier to try it once

But do not overdo it - ammonia should not leak and get on the back, abdomen and, especially, on the wings.

IMHO, the fact is that a) when piercing the chitinous integuments of a butterfly, not a neat round hole is formed, but a hole with uneven edges (the needle does not pierce, but rather breaks through the integuments); b) when piercing, the needle tip with a drop does not enter instantly, but over a certain period of time, and this time enough to get a drop of ammonia inside the insect's body.

I would like to consult with experienced overseas residents:
are there any ways to treat beetles such as Coccinellidae and Cassidinae, which, after drying the collection material, minimize the loss of intravital color of imagos? in ladybirds, I experimented with various substances and concentrates, a freezer, and even removing the wings - all the same, the elytra look somehow unnatural (lighter or darker, loss of contrast)

As for Cassidinae, unfortunately, there are no ideal ways to preserve their natural color. Mother-of-pearl (and so on. in this genus, the bands on their elytra generally depend on circulation during the life of the hemolymph, and it is impossible to preserve them after death.
As for Coccinellidae, there are more or less 2 less suitable ways:
1) Killing with high temperature (beetles are placed in a test tube or a penicillin-type vial, which are lowered for about 20 seconds into boiling (just boiled) water (option-coals of a fire).
2) soaking in snuff (I do this: in a jar like from under a cosmetic cream, I pour tobacco on the bottom, make a layer of gauze, and on it - beetles. It takes quite a long time (at least a day), but the result is quite acceptable. I even once as an experiment Cassida vibex retained its natural color, not to mention the cows.

About 10% ammonia from the pharmacy another question
Last year I got caught, I don't remember exactly, metalloid gamma or ypsilon , taking almost 1 ml of ammonia on her chest, she flew on as if nothing had happened, after taking 1 ml of pure alcohol, it didn't help either . Put on the needle let there domoritsya figase tried to fly up with the needle
I had to kill myself with a slipper

Sovka mutant
Morim with ethyl acetate, mutants will not pass

Can you tell me if it is possible to restore the color of the upper lip in racehorses after freezing with ethyl acetate?

does the upper hood get dark for racers? 0_o
and because of what is not clear?
If the cause of fattening is a typical problem of racehorses, then you can try ethyl acetate or gasoline, peroxide..

some advise to use gasoline instead. There is one thing but the truth is that insects get stale from it, but if you disassemble the collections on the same day, in principle, you can use it. Garazdo gasoline is better than any varnishes, dichlorvos, etc. since it is low-toxic (in comparison, of course), publicly available and butterflies from it, for example, do not change color. With ethyl acetate, of course, you can not compare, but if there is nothing, and you need to starve-feel free to go with a jar to the nearest gas station

if you have friends at the Chemical Faculty of Karazin KHNU, please contact them, they are definitely there. If there are none, this is bad and you need to look for them.

Morim ethyl acetate, mutants will not pass

Caught the light on May 9. The catch is a few moths, like some small sickle-wing, one scoop and a micra (alas, I'm not good at determining). So, moths and scoops fall asleep in eternal sleep in about a minute, and a trifle in general in 10 seconds. I've already stocked up on syringes and ammonia. This is probably a large hawk moth and day need to prick. And so if you pour a killer amount of EA on cotton wool in a stain, it will stain very well. By the way, I use the method suggested by cajarc-a rather thick layer of cotton wool on the bottom of the jar, and on top - a circle of thick cardboard paper with a circle of cotton wool attached to it. Only the diameter of the jar must be accurately estimated, otherwise I have butterflies crawled between the wall of the jar and cotton wool and got dirty EA.

The use of ethyl acetate in mordants does not mean that you can buy it only in entomological stores of which there is only one in all of Russia.
This is a common solvent, a chemical reagent allowed for free sale. Accordingly, you can buy it in almost any store specializing in the sale of these very chemical reagents. As HCH or HCHDA and at a price ten times lower than "entomological".

For example, here:

And if it's not enough for velkam in Yandex, there are still two dozen companies selling this very difsit in your city. Although I personally got the impression that you were just too lazy to type "Kharkiv ethyl acetate"in the search bar...

Those. the darkened lip is not from EA, and if the horse is wet in EA, it will correct delo

About ethyl acetate. If you can't get it , go to the store that sells nail polish remover and read its composition. Where" acetone " is not needed, we don't need it. And it is necessary where "ethyl acetate" or "ethyl ether of acetic acid". Use it for your health!

A very good way to zamorki microbabochek and any delicate material. One or two specimens are caught in small test tubes with a perforated lid, and then these tubes are poured in a pile into a bag with cotton wool soaked in ammonia. And for the night. The quality is perfect and they do not dry out, so you can prick them in the morning. Very convenient.
My friend-Peter Ustyuzhanin uses this method for zamorki paltseklylok. And I spied the method from the Dutchman.

Dear colleagues.
Please tell us who can do what.
We need a perfect steamer.
Dry (so as not to soil the winged ones-mainly eardrums and diptera), strong (there will be bumblebees), persistent (the trap will work for 10 days) and not too toxic for the accountant. Ideally, it should not frighten and attract insects with its smell.
You can't buy industrial fumigators now for a number of reasons, and making homemade "death cubes" (dichlorvos+molten paraffin) is a pity for your health. Permethrin and other filth - very bad even for a man in the prime of life.

Here is a dreamer's essay.
I forgot to add that these are color traps -- buckets with funnels

To the above problem. Has anyone tested anti-flea collars for pets for similar purposes? There are also models where, in addition to acaricidal, lice - and flea-bearing properties, anticomarin properties are mentioned.
And yet, will insecticidal crayons ("Mashenka" and others) based on deltamethrin be suitable?!
Share your thoughts.

Crayons perfectly kill beetles. The color doesn't change, except for the cassids, of course.

Freezer t=-5 for 15 minutes - so far the most affordable and safe stain)) In the field, you can also use it in a car. Who knows if it is possible to preserve the color of the same cassinae (Chrysomelidae, Cassinae) in solutions of any of them?

Don't tell me. In relation to butterflies, I cooked them at the dacha for a minute in ethyl acetate, then on the mattress in a plastic container. After fishing in the freezer - there is even probably below minus 5. So they lay there for about 10 hours, then I took them out and went home. In 3 hours, some (scoops, moths) were reanimated! Well, then at home again in the freezer. To the forefathers.

So I'm talking about beetles. I have no experience with butterflies at all. from coleoptera such survivability is possessed for example by weevils
freezer I mean as a way of preserving the color of the integument

Colleagues, why are you all so fixated on ethyl acetate?
In fact, in the old days, coleopterists preferred pear essence (iso-amyl acetate or iso-butyl acetate) rather than it. The advantages of this retainer are that it is less volatile and works much more smoothly. In a jar of sawdust soaked in grushevka, beetles can be kept for a month or more without harm to them. And it smells, I must say, much nicer.
Well, I myself prefer cyanide stains, which can be used "for years" with guaranteed results, if you avoid high humidity inside.

Well, I will say in relation to butterflies. So far, I've learned from my own experience that he's a VERY good sailor. Hawk moth takes 2-3 minutes - they calm down and tease me with ammonia. Ah respectively pyadenitsy 1-2 minutes, pro mikru at all not speak. All this is probably due to the high volatility, due to which a high concentration of EA is quickly created in the stain after closing the lid, which is exactly what we need.

Well, it also burns very well!!! I have a cat in my dacha right now. I come on weekends - he collected ticks in a week. I pull them out with cotton wool, put the cotton wool with ticks in a hole dug in the ground, put another newspaper there, fill it with ethyl acetate, throw a match and... BURN!!! And after 5 minutes, you can hear the sweet clicks of exploding ticks and the smell of meat...

Colleagues, why are you all so fixated on ethyl acetate?
 

I have been using ethyl acetate for many years. Given the fact that I collect mostly karabuses, it didn't create any problems for me:
1. Steams very quickly
2. Leaves no traces
3. The insect remains soft
4. It can be stored in ethyl acetate for a long time, which is very important with a large amount of material.
This year, when working with ethyl acetate, we encountered the following: Archiplectes juenthneri avadcharensis Kurnakov-ground beetles of blue color, when soaking they turned completely black. Similarly, Sphodristocarabus janthinus dvorshaki Mandl., which have a slight bluish tint, turned just purple after treatment.
This suggests that some other drug is required when working with such species.

For zamarivaniya day use in camping conditions ethyl acetate. The entire daily fee is settled in an airtight container (the store thought that I took so many of them for the microwave) plus cotton wool with a drop of EA. In the morning, a couple of hundred corpses in plastic bags. If I go out for a day or two, I leave it until the freezer (a wonderful thing!). After these manipulations, the material is always well straightened. Quite a long time ago I used gasoline-dubeyut. Acetone nail polish remover also tans. Big night and sailboats with tails I stake with 10% ammonia. The second ones in the bags constantly bend their tails and eventually break off every other time.
I wanted to order EA on the Internet, they didn't sell it to me, they say you can't send such liquids. When I was in Moscow, I bought 0.9 from Zhuravlev. I transported it on a plane in an ordinary plastic sprite bottle (so that they would ask fewer questions), in which it still stands since February 09. The bottle is alive and not melted.
With beetles, almost everything is the same, although sometimes the material from the frost does not deal very well.

Good day to you colleagues, I apologize for the interference, I just haven't unsubscribed for a very long time. Yes, as I look in this section, I'm not the only one. Those who have problems or difficulties with the extraction of ethyl acetate, I bring to the attention that it can be purchased at any hardware store and several times cheaper than in specialized or chemical stores. for example I have a chemical store below my house where EA costs about 200 rubles a liter and across the street there is a market where the same quantity is twice as cheap in the paint and varnish department. Cheap and affordable so I advise everyone

Well, as for any hardware store, it is probably only in your country, in Moldova...

it meant markets where there are patches with paint - it goes there as a substitute for acetone or something like that.
If we have it, then it should be anywhere)

Try to find out in chemical reagent stores for laboratories or in chemical vessels stores. Here in Stavropol I buy exactly there.

In large construction supermarkets, in the department with solvents, Ethyl Acetate in packs of 0.5 and 1 liters. the cost is slightly more than 2 green per liter.

Just bought ethyl acetate in Donetsk for 22 UAH. per liter in the company "Synbias", engaged in reagents, chemical vessels, etc.

Question to Muscovites: Has anyone recently bought ethyl acetate in Moscow and where? It's just time to go shopping .
P.S. Other than that: http://www.entomon.ru/online/goodsGroup.php?id=4 The price there bites painfully.

Thank you very much!

For 1 liter We bought three liters (22 x 3 = 66). Packaging - white plastic pleasant bottles with a red lid.

in Moscow, on Izmailovskaya Street http://www.labtex.net/contacts.html although after the recent stremnovato with bottles of EA on the subway shied away, they can lynch, although from the click of only two stations, if my sclerosis does not change a kilogram bottle 2 years ago cost something about 150 rubles, right now probably 250 rubles, but I think it's not more expensive than pyatihatki
Look at the Savinsky highway we have a kind of house 10 (against the women's consultation red brick house), in the household they have an assortment of solvents of twenty types probably, I recently" Galoshes " there took and something tupanul all did not look it may well be EA
