Rivaling pesticides and a dearth of flowers, the parasitic mite Varroa
destructor presents a tremendous threat to western honey bees, Apis
mellifera. A longstanding, but minor, pest for the Asian honey bee Apis
cerana, these obligate bee parasites feast on developing and adult
A. mellifera across several continents. Varroa reproduction is limited to a
short window when developing bee pupae are concealed in wax cells. Mated
females target developing bees just before pupation and then have about one
day to initiate reproduction, eventually laying one male and up to several
female offspring. Female mites often fail to reproduce at all, instead
waiting in cells until their bee host finishes development and then
hitching dangerous rides on a succession of adult bees for up to several
weeks, before scouting for a new host pupa. In this issue of Molecular
Ecology, Conlon et al. (2019) have explored mite reproductive success via a
clever and thought-provoking association study. In so doing, they have
identified a protein whose actions could be integral to the dance between
bees and their mite parasites.
