The varroa mite poses a serious threat to the
Canadian beekeeping industry. Resistance to the fluvalinate strips
(Apistan) commonly used to control this pest has recently been reported in
many regions of Canada. There are also reports of varroa mites in the
United States and Canada developing resistance to coumaphos, which is
another easily-applied alternative varroa treatment. Therefore there is an
urgent need to develop reliable alternative treatments for controlling
varroa mites.
The overall objective of this research is to
develop effective and economical methods to reduce the impact of Varroa
destructor on honey bees under Canadian honey bee management systems.
The specific objectives of this study are to examine how environment of
indoor and outdoor wintering systems interacts with bee genetics and affect
colonies to better tolerate and/or reduce their varroa mite population. The
applicant will also determine if the use of this bee stock will allow for
higher treatment thresholds to determine if mite resistant stock can be used
in combination with acaricide treatments without sacrificing honey
production.
The Manitoba Queens Breeders Association and the
Canadian Bee Research Fund are funding partners in this project.
