When I was in college we used a product called "fly-nap" that may have been less volatile. It was a liquid in a small bottle and we put it on a cotton ball in the culture tube until they went to sleep. It kept them under for about 30 minutes and was easy to use.

Subject: [DCHAS-L] ether for anesthetizing fruit flies

Hi everyone,

We are looking to renovate a Genetics teaching lab that has the students using ethyl ether to put fruit flies asleep. This is a common method of doing this, put certainly has its drawbacks when you consider the ventilation strategy (ether vapor is very heavy).

I'm wondering if anyone has been successful in having 12-14 student stations using this chemical in a teaching setting (on the bench) and keeping the exposures and smell down? Keeping in mind that fruit flies will get sucked up into local exhaust if they are too close!…

In addition to floor level exhaust diffusers, what else would you recommend and how many air exchanges for the room?





P.S. I'm pushing for CO2, but may not get what I want.
