So. . . I'm assuming you want to acquire the venom, and then treat the caterpillars in different ways with it? Very interesting! I'm not familiar with wasp/bee research, so I don't know how the real experts do it. You might look for web sites or books that deal with beekeeping. I have a couple of ideas you might also try. Find a good diagram of the anatomy of your wasps, locate the venom sacs, then dissect a few wasps and see if you can remove the sacs intact. Or, use forceps to grab a live wasp by the wings (I suggest cooling her down in a fridge first so that she's slower and more docile), then give her something to "sting" - perhaps a glass with plastic wrap secured over the top. let her sting through the plastic, and see if you can get a drop of venom. I'm not sure if the wasp would need the stimulus of puncturing something to sting or not. Perhaps she would sting directly onto a petri dish. Or, you could always hold the wasp up to a caterpillar. . . Good luck! [Get an adult to help you!!]
