Greeting to all!
I've been requested to ask the bionet.drosophila group about your current
(or past) use of pesticides to control common pests (i.e., cockroaches,
silverfish, ants, etc.) in areas where fly media is prepared and flies are
For obvious reasons, we use no pesticides in these areas, only sticky
traps. However, sticky traps are only marginally effective and the pest
populations are thriving! The Urban Entomology Extension Specialist from
N.C. State Univ. and the pest control contractor to Duke Univ. have
recommended that in lieu of appying a contact or residual pesticide, we put
out Max-Force baits (commercial formulation) or an avermectin bait in gel
form (Avert) or a combination of both. However, neither expert could
guarantee that the Max-Force or Avert would harm Drosophila. There is some
(paranoid) concern that pests that ingest these compounds or come into
contact with them may get into the components from which the media is made
or they may contaminate glass vials they may walk across, causing mortality
in lab stocks.
Does anyone have any thoughts or comments on this matter they would like
to share with us? You may post to this group or respond by email to the
address below. Thanks for your help.
