The effect of DEET on chemosensing of the honey bee and its parasite Varroa destructor

Mortality of untreated VSB (Varroa Sur- viving honey Bee) colonies compared to treated control colonies over a 7-year period. Percentage of swarming in the VSB colony

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

Colony strength and survival analysis We found significant within-treatment dif- ferences based on mite donor colony for adult bee population in apiaries inoculated with mites

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

Worker honey bees exposed to acaricide presented significantly less time spent performing grooming behavior after a Varroa mite was introduced onto its thorax.. Both the dose of

Also, I checked each frame of worker comb in the lower two hive bodies of each colony’s hive to see if the bees had added a patch of drone comb, either within the wooden frame

To investigate the changes in infestation level of mites on adult bees during periods with little or no brood rearing, we equipped 10 colonies with net screen bottoms for col-

The main aim of this study was to deter- mine if the incorporation of the SMR trait into the “MN Hygienic” line of bees would decrease the mite level in the HYG/SMR colonies relative
