what is your method to kill and preserve bugs in collecting
trip?
killing jar filled with some ethyl acetate wetted tissue? if yes,but
this is just killing the bugs,what is the way of preserving ? in
alcohol bottle? or just put several alcohol drops into the soft
tansparent plastic bags to keep the insects wet till get back home? if
directly kill the bugs by putting them into alcohol bottle,their leg
joints will become relativlly stiff and hard to relax again. i was
told if killing by ethyl acetate jar,and don't put very soon the bugs into the soft transperent plastic bags,in stead just wait for some
hours or half or a whole day (let the bug cropse go on stay into the
ethyl acetate jar) enough time (several hours to a day),then ok can be putted into the soft transperent
plastic bags to preserve till get back home(collecting trips sometimes takes many days) ,so their leg joints won't become stiff? and won't got rotten?

When I go collecting, for small insects I use killing jars with cotton dropped with nail polish remover. I mount small ones immediately after killing in a box I've prepared. As for the larger ones, I use injection with spirit and store them in envelopes or jars.

killing with ethyl acetate (EA) is the best way.
You can prseve them around 1 yea (or moreà r in jar contaning sawdust with small EA. Better is to put them in fressez.
You cana also dry them for mounting of stock. There are easily relaxed if killed with EA.
for injection (beetles and lepidoptera) the best is ammoniaque (NH4OH).

To kill leps, I have been using cyanid jars for 25 years now.
To spread them when they are dried, I inject gin as I have learned on this forum few months ago (it works better than hot water).

I use 75% alcohol to kill them in (very easily to find in anywhere in Asia) and I normally packaged them all and dry them before I bring them back. Especially with the Cerambycidae their antennae is so easily to get damaged, even in alcohol or ethyl acetate. Some time takes me up to a week to packaged them all.

Gin, really? I missed that one, that's interesting. I'm going to give that a try, I use hot water as well. Do you inject anywhere specific, such as in the wing joints? Relaxing is my least favorite thing, anything to make it faster and easier is great to know.

cyanide is impossible to get in China,forbidden for sale. EA jar is a very good way i saw other perfessional collectors also use when collecting,just to see if there're other methods or better way out here. the next season i will use EA jar.
Ray,what's your methods to dry the specimen before take it home? mounted them on stiff cards? this is normall my last job which was done at home after taking the fresh hunted specimens back home.

I mainly collect during the night and I have a lot more time to packaged them during the day (packaged them like noramlly on cardboard individually and dry them under the sun) unless in sping I can find flowers to collect cetonidae and cerambycidae. This way they will be all ready to go into my collection when I get home and I never had one specimens damaged. Personially I feel the only way to stop the beetles from falling appart is to dry them as soon as possible. Especially with all Lucanus sp.

Hi Wei,
I kill beetles in alcohol and store in 80% alcohol till ready to pack .
You received my specimens before and no complants , all good.
Cheers

starlightcriminal < I inject gin the same way I injected hot water (in the bottom of thorax). Gin is quicker than hot water, it doesn't stain wings and it dries quicker on spreading boards. I also think it avoids moistures.
I inject the butterfly with gin + I deep its antennaes into gin. Then I put them in a tupperware for one night. Then the butterfly is as fresh and very easy to spread.
Thanks to the Insectnet member who learned me that method (cannot remember who... sorry).

Hi Jack,
sure no any complains,your specimens were prepared perfectly i love them very much!
this time i found many problems myself when field work,wrong or unperfessional ways to kill to preserve them. so i posted this new discussion to learn from all of you. see the differences of methods. and to use next time.
how it would be great if later time someone will attach some pictures of the processes when doing this work,killing and preserving specimens. pictures tells more directly and vivid.
