The tracheal mite, Acarapis woodi (Rennie), parasitizes the
honey bee, Apis mellifera L., an insect used extensively by humans
for pollination of domestic crops and for bee products, primarily
honey.
This parasite was first discovered in 1921 on the Isle of
Wight, a small island situated in the English Channel...
Acarapis mites have been present in the United States since 1984 and are presently considered a threat to honey bee populations in North America. They have
been present in Europe since 1921 where infestation rates have now dwindled to a
level that is not considered dangerous. Consequently, accurate information on...

The prevalence of Tropilaelaps mercedesae and Varroa destructor in concurrently infested A. mellifera colonies in Thailand was monitored. We also assessed the fecundity of T. mercedesae and V. destructor in naturally infested brood and in brood cells deliberately infested with both mite genera. Results showed that the natural co-infestation of...
Meadowfoam (cultivar Mermaid) is an entomophilous
winter annual oilseed crop that has historically produced
an average of only two of five seeds per flower. Reference
to inadequate meadowfoam pollination exists in the literature,
but quantitative evidence is lacking. Studies were
undertaken to: 1) quantify meadowfoam pollination requirements
and 2) evaluate...
The biology of the two external Acarapis mites of honey bees,
Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler
was studied. It was observed that both Acarapis species have similar
developmental period (8-9 days) with males emerging earlier than
females.
Mite load and infestation rate of A. dorsalis decreased as bees...
