Varroa mite life cycle has two stages (Fig. The ectoparasitic mite, Varroa destructor, shifted host from the eastern honeybee, Apis cerana, to the western honeybee, Apis mellifera.Whereas the original host survives infestations by this parasite, they are lethal to colonies of its new host. destructor and its vectored honeybee viruses became serious threats for colony survival. Apidologie 30(1), 31–36 ... Rath, W. (1999) Co-adaptation of Apis cerana Fabr. Apis cerana is the natural host to the mite Varroa jacobsoni and the parasite Nosema ceranae, both serious pests of the Western honey bee. Understanding the varroa mite’s reproductive biology will therefore allow us to better manage this important pest. Varroa destructor also faces reproductive limitations in A. cerana colonies, as it can only successfully reproduce on A. cerana drone brood ( Boot et al. cerana colonies due to several host defense mechanisms that impact varroa reproduction: mite infertility in worker brood, entombment of drone brood infested with multiple mites, and increased hygienic behavior (reviewed in [4]).
Varroa incurs only limited damage toA. Ignoring the varroa mite problem and failing to manage it in some way will almost always result in catastrophic colony loss. 1999 ) due to the efficient removal of infested worker brood ( Rath, 1993 ). Varroa destructor is an ectoparasitic mite of Asian or Eastern honeybees Apis cerana (A. cerana) which has become a serious threat to European subspecies of Western honeybees Apis mellifera (A. mellifera) within the last century.V. They are relatively harmless in their native Asia, as the eastern honey bee (Apis cerana) has evolved to handle them through better grooming practices. Nosema ceranae was originally a pathogen of the Asian honey bee, Apis cerana. This parasite was first detected in North Carolina in 1990, having been introduced to the US only three years earlier.

Natural Varroa mite-surviving Apis mellifera honeybee populations Barbara LOCKE ... currence of two genotypes of Varroa jacobsoni Oud. The Varroa mite is originally native to Asia, where it was first discovered on the island of Java in Indonesia over 100 years ago. The mite initially preyed on the Asian honey bee (Apis cerana). The Life Cycle of Varroa. Having coevolved with these parasites, A. cerana exhibits more careful grooming than A. mellifera, and thus has an effective defense mechanism against Varroa that keeps the mite from devastating colonies. It has eight legs, belongs to the same class of arthropods as the spider and it feeds on the blood of honey bees.
(Apis cerana)(Figure 3), to exploit a naïve host with inadequate innate defenses. Apis cerana demonstrates a high level of hygienic behavior that efficiently removes mites, along with uncapping, removing, and entombing of infested brood during mite reproduction . Apidologie 30(2-3), 970–11 The Genus Varroa is currently represented by at least four species of obligate ectoparasitic mites ():. In some ways, this characterization is the opposite of the truth.

The varroa mite (Varroa destructor) is the most serious pest of honey bee colonies worldwide. in North America.
