Are Fruit flies everywhere? With a bucket of fermenting Jerusalem
Artichokes in the lab we were quickly over run with them. Placing a few
in a clear 500 cc Solo Plastic cup and injecting in a known amount of
CO. Report both time and concentration when they die might work. Gas
pulled from a stream of CO from a tank using a gas syringe and injected
through the wall of the cup. We need to see if it kills them at
concentrations we can use. But I don't see someone sitting and staring
at the fruit flies all night! Still need a buzzer.
