OVERWINTERING PERFORMANCE OF HONEY BEE COLONIES HEAVILY INFESTED WITH ACARAPIS WOODI (RENNIE)

Russian honey bee (Hymenoptera: Apidae) colonies: Acarapis woodi (Acari: Tarsonemidae) infestations and overwintering survival.

Honey bee, Apis mellifera L. (Hymenoptera: Apidae), colonies infested by parasitic mites are more prone to suffer from a variety of stresses, including cold temperature. We evaluated the overwintering ability of candidate breeder lines of Russian honey bees, most of which are resistant to both Varroa destructor Anderson & Trueman and Acarapis woodi (Rennie), during 1999-2001. Our results indica...

The Occurrence of Acarapis dorsalis, Acarapis externus and Acarapis woodi Mites in Honey bee Populations Surrounding Poitiers, France

An Easy Dissection Technique for Finding the Tracheal Mite, Acarapis Woodi (rennie) (acari: Tarsonemidae), in Honey Bees, with Video Link*

Since the introduction of varroa mites (Varroa destructor Anderson and Trueman, 2000), the impact of tracheal mites on bees has been largely overshadowed or ignored. Tracheal mites are still present in bees, and may be responsible for some unexplained colony losses. If they cause bee mortality, it is important to be able to identify their presence and at what levels. This paper illustrates a qu...

APICULTURE AND SOCIAL INSECTS Infestation of Tracheal Mites (Acari: Tarsonemidae) in Feral and Managed Colonies of Honey Bees (Hymenoptera: Apidae)

J. Econ. Entomol. 86(3): 712-714 (1993) ABSTRACT We tested a population dynamics model that predicts that swarming of honey bees, Apis mellifera L., is a regulatory process of tracheal mites, Acarapis woodi (Rennie), parasitism. If the model is correct, then feral colonies that are free to swarm should have fewer numbers of infested worker bees, infested workers should have fewer numbers of mit...

The dynamics of virus epidemics in Varroa - infested honey bee colonies

1. When the parasitic mite Varroa jumped species from the eastern to the western honey bee, millions of infested bee colonies died. Recent work has revealed that the probable cause of this collapse is that mites provide a new route of transmission, by acting as a vector, for certain bee viruses. 2. Using a mathematical model parameterized by recently collected data on bee viruses, we investigat...
