In researching my original question about the potential affects of
Apistan
on queen-rearing in splits i searched the bee-l archives and found a
few
posts from 1995 that discussed the possibility that queens stopped
laying
while the strips were on and/or that e brood morty occured. Consensus
of
the posts seemed to be that, if either occured, it was probably
related to
early recommendations for heavier dosing than what is in use now.

Hi Greg,
An article in the American Bee Journal Feb. 1999 reported that
Apistan treatment did have negative effects on drones reared while
treatment was in the hive.  The researchers did not report any
research on possible effects on queens reared during treatment but if
you don't have good drone production mating could be a problem.  The
conclusion of the article was to not have the strips in the colony
during drone production.
