A scientific note: migration of tracheal mites (Acarapis woodi) to old winter honey bees

The tracheal mite, Acarapis woodi, has been widely studied since it was first discovered in 1919 (Rennie et al. 1921). It is generally accepted that the mite migrates from an old host bee to a young bee less than 4 days old (Morgenthaler 1931; Bailey 1958; Gary et al. 1989). During winter months, however, there is evidence in temperate areas of mite prevalence levels increasing in infested colonies (Otis et al. 1988; JBMcM, unpublished data). In many cases, the levels have been observed to increase dramatically, and this at a time when there is no brood or young bees in the colony. While this may be explained by the unlikely event of uninfested bees dying, and at a greater rate than infested bees, a more likely explanation is that old bees are becoming infested.
There has been only one reported experiment to demonstrate that the tracheal mites will migrate to old bee hosts (Smith et al. 1991). However, the rate of migration was zero in one colony and only three out of 86 bees in a...
