Back when I worked with codling moth, we actually used the cold to keep them either motionless or slow moving for some of the work we did with them. To introduce cold, we either put them into a fridge, or we used bags of ice the moths were in contact with.


Good luck!

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