Reproductive success of the parasitic mite (Varroa destructor) is lower in honeybee colonies that target infested cells with recapping

In our study, coumaphos residues ranged from 36 to 159 mg/kg in central brood combs seven months after a single CheckMite® application.. These residue levels were close to 100

Significantly more infested pupae (P < 0.001) were removed than non-infested ones: on the whole, 17% of artificially infested cells were uncapped and emptied by bees after ten

The European honeybee, Apis mellifera , is the only Apis species that does not have a natural parasitic brood mite but is nevertheless highly susceptible to at least two mites that

Bee extracts for virus detection In order to determine which bee viruses were present in these colonies when sampled, and in what amounts, a composite virus purification pro-

The lack of sig- nificant variation in the infestation levels in the brood could have resulted from the lack of differences between groups for hygienic behavior, brood attractiveness

The fact that (i) the proportion of colonies that died over winter decreased significantly (Fig. 2), and (iii) the mite infestation rate of adult bees in the fall

In general, in- sect frass and its volatile components provide cues in habitat location (Weiss 2006 ). In this study, avoidance of an infested cell may be one of the reasons for such
