Insects fumigating

Still soak. Try soaking in a hot solution of fairy perfume, and then hold in alcohol for an hour, then straighten. The rest of the smell will disappear by itself.

Thanks a lot, I'll try it this way.

I have such a stain for butterflies:

In it, butterflies do not live long, the scales do not fly around. On a ball of cotton wool under the grate drips liquid "Weasel" (it was written about earlier). I also fill it with butterflies when soaking (if anyone has any questions about soaking, see the section soaking insects)

Dear participants,
What to do if a butterfly is accidentally forgotten in the stain and during the night managed to "get dirty" there, having oversaturated with ethyl acetate vapors?
I took it out of the stain - after a few minutes, one pair of wings was completely restored, and on the second one there is a large "greasy" spot at the ends.

Put it in gasoline for a day.

But it is better to pre-straighten. After soaking in gasoline, straightening can be very difficult.

Ammonia! and no problem!!!

Can't make ammonia yellow, or even change its color?

Maybe. In some green butterflies.

Melanargy turns bright yellow

Ammonia in Troides rhadamantus (Lucas, 1835) causes the bird's wing to turn golden, yellow, and brown!

Gentlemen biologists, there are traces of chloroform and methylene chloride.Write to pm

methylene chloride.

Yes, you will win the Nobel Prize in Chemistry!!! A new organic compound was discovered. Or maybe your item is simply called something else: ethylene chloride or chloromethane.

However, we will leave the questions of chemical nomenclature. I'm not sure if "methylene chloride" and the like are suitable for soaking insects. However, in some work, dichloroethane was cited as an example of a killing liquid.

vafdog, respect for your support, I was too lazy to post a link from Wikipedia myself.
But now biologists know that dichloromethane and methylene chloride are one and the same!
Chemistry rules!

Has anyone ever tried to use acetone???

I've tried it, but it's a bit of a mess. I haven't found anything better than ethyl acetate (chemical pure) yet. Insects are soft even when soaking dry material.

I went to building materials, bought 0.5 liters of ethyl acetate in the department with solvents (in the equivalent for $ 3). It will be enough for the season, it will still remain, why experiment?

I have never seen it in our building materials, although I look at it in such stores all the time: even if there is a question, they don't know what it is. Although you can get it in Moscow, but not in building materials.

I took it from an office that sells chemical reagents-I am sure that there are more than a dozen such companies in your area

Well, I'll tell you straight about a lot of things: I don't know.
There is one shop I know in which ethyl acetate is stopudovo.
I took there freely and cheaply last summer a kilogram of HC http://www.labteh.com/productID15298/ and it will last me a long time.
Here's the store: http://www.labteh.com/retail.html
And here is the list for the moment: http://www.labteh.com/categoryID281/offset1050/
This office has already been mentioned here more than once.
If you are geographically located in Moscow, I recommend it

I have a question here..........
All the time in the stain for beetles laid as usual crumpled toilet paper, blotting paper, etc
. And then a man gave me a cork crumb. And it seems-as well for laying in the stain
Has anyone used this and what are the advantages over standard methods?
Or maybe it is used for something else?
I'm being stupid

It is used for this purpose (mortification and transportation of coleoptera). I used it. On expeditions, when there is a lot of material, it is convenient, practical and safe. But there is one drawback - the wet crumb sticks to the beetles. When everything is shaken out of the jar, you need to let the material dry a little and then you will have to fan it with a brush.

I use small lime shavings as a filler-I sift through a 12 mm sieve, what has failed I pass through 5 mm to sift out small things and dust-the remaining stain is 1/2 or 2/3 of the volume. sometimes it sticks to the material, but it doesn't create any special problems. it retains EA well (the main thing is not to pour too much), excess moisture and bug secretions. sometimes I leave beetles in such stains in the refrigerator door for six months - I get them out like they're alive. but poking around in paper porridge is disgusting

No porridge. EA is soaked in cotton wool, which is in the lid of the stain, and the paper is laid in the jar itself. I use banal cans of coffee "Moccona": they are very good under the stains go and sealed. Dmitrich here has already recommended these for a long time. Why put EA on paper? This is acetic acid ether and it is volatile: vapors quickly fill the jar.
P. S. Link on Dmitrich's post in the same topic and thank him for suggesting it. The system works great.

I have repeatedly dealt with collecting sawdust / shavings impregnated with ethyl acetate. For orthopteroids (in the broad sense of the word, i.e., Polyneoptera), this method is not suitable - cockroaches, erect wings are very badly damaged, earwigs simply fall to pieces.

Yes, this method is unsuitable in my opinion for anyone . This is like first bathing an insect, and then also "walking with a skin" for pliziru, and some beetles generally need to be starved without any filler: elephants of the genus Lixus, for example. Large water beetles are generally better immediately pricked after capture without soaking.

it's more a question of which group to work with. I do not collect cockroaches, erect wings and earwigs, and with beetles even very small (from 1.5 mm), covered with hairs (olenka, glafirids) and scales (small elephants) for the last 15 years, I agree, deer, rhinos and other large animals should be immediately pricked with ammonia, but so that they do not dry out on a week-long trip, then I still put it in the stain. you just don't need to tamp your knee, but take a few stains on long trips.
but if it is important for someone to keep the stuck pollen on the lixus or larina, then of course, it is necessary to sea in a different way. the choice of methods depends on the goals

Collecting insects in sawdust with ethyl acetate, in my opinion, was invented by the "bugs". In any case, I chose my "animals" from mainly coleopterological collections. I don't know about beetles, but it's better not to collect orthopteroids that way.

If I remember correctly, these were all tropical gatherings in the field.

Sawdust and cork chips are still no longer intended for soaking beetles, but for their transportation. Imagine that you have caught a decent amount of material. And you need to carefully lay it out on the mattresses. And this is a considerable amount of time, which is usually not available on an expedition. Next, imagine walking a long route with ascents and descents, with dropping the backpack on the ground, often using it as a seat for halts. And in this backpack, even in a box-mattresses with precious material. Therefore, several small containers (usually plastic ones) are usually used. The container is filled with frozen material with crumbs, a little ethyl acetate, and data about the capture point and date are written on it with a lacquer marker (washed off with alcohol or solvent). And already no turning over and shaking is not terrible. And at home you can safely uncork and straighten. This method of transportation is certainly not suitable for more delicate, hairy or easily erased pigment beetles or other insects. For them - only mattresses or a tattoo. And if it's just a day out in the field from home, you shouldn't bother with crumbs or sawdust. It is better to use filter paper. By the way, paper towels are good, but not from thin paper, but from dense and rigid.

Collecting insects in sawdust with ethyl acetate, in my opinion, was invented by the "bugs".

No offense said to the "buggers" who invented it
I recommend such beetles to get acquainted at least with the Soviet literature for schoolchildren.
The first two books that came across: Kozlov and Ninburg "Your Collection"; Plavilshchikov N. N. "Determinant of insects" where the device of a classic stain for beetles is described in detail.
No sawdust soaked in ethyl acetate is not in sight. And the jamming system works with a bang.

You are right Vasily, in the Sovkov manuscripts, and even in the royal ones, there is not a word about ethyl acetate
sawdust, napkins, and even a sneaker on the dorsal surface, who wants to, and morits-the main thing is the result!

...Kozlov and Ninburg "Your collection"; Plavilshchikov N. N. "Determinant of insects"...

... in the Sovkov manuscripts...

Forgive me generously, but the term "Sovkovskie", which is so often used (by the way, on business and without business) by modern youth, in my opinion, is hardly applicable in relation to these classic publications, on which more than one generation of entomologists (both amateurs and professionals) grew up. It was heartbreaking, you know...

...who wants to, and morits-the main thing is the result!

But this is true - everyone has their own taste: one likes watermelon, the other pork gristle , And arguing, trying to convert others to their faith is not a grateful occupation. Anyone who wants to, someone else's experience will probably take note of it anyway, if it turns out to be really useful.

I apologize for the harshness, I myself learned to read from these books, but Vasily was too zealous and peremptory to incline me to toilet paper

I apologize for the abruptness, I myself learned to read from these books, but Vasily was too zealous and peremptory to incline me to toilet paper

Nothing overzealous. Just in my opinion, there is no alternative to these historical, time-tested methods. And don't reinvent the wheel .

bugs - only so, imho even stabbed need to withstand mimnimum night in the stain.
(well, if there are no special contraindications - long pubescence, wax deposits)
judging by the quality of the spread of some comrades, it is also necessary to be able to marinate beetles.
taking someone else's something with cotton wool-you can then namayatsya....
