The number of drones and genetic diversity among drones are
essential components to a well mated queen. Varroa destructor
preferentially parasitizes drone brood, and is thought to be
responsible for the loss of feral populations that once provided
additional drones for honey bee mating areas. It is necessary to
use miticides (e.g. coumaphos) in managed colonies to control V.
destructor. Little is known about the sublethal effects of these
compounds, which are directly introduced into the hive. In
response to growing concerns about the successful mating of honey
bee queens, drone honey bees were exposed to coumaphos, during
drone development. Sperm and seminal vesicles were sampled
among drones that were exposed to coumaphos and drones that
were not exposed to coumaphos, but were parasitized by Varroa
destructor. There were no significant differences found between the
two treatments in terms of seminal vesicle size and sperm
numbers. These results indicate that drones parasitized by V.
destructor have similar sperm quantities as drones exposed to
coumaphos. / Graduation date: 2004
