In three additional colonies assayed for mite biting behavior, the average frequency of grooming (anova: F = 0.7956, P = 0.4645) and the average biting events (anova: F = 0.7033, P = 0.5049) did not differ among nurses, guards, and foragers.
We tested defensive behavior and mite levels after colonies reached the standard size.
Among the mechanisms that may maintain a low Varroa destructor mite infestation are hygienic behavior (Boecking and Spivak 1999) and grooming (Mondragón et al. 2005).
On the basis of species- and sex-specific differences in adaptation to ephemeral spider mite prey and mating behavior of P. persimilis, N. californicus, and A. andersoni, we pursued three major hypotheses.
Honey bees reduce the impact of pathogenic bacteria, fungi and parasitic mites through hygienic behaviors, where workers identify and remove infected larvae from the healthy brood [ 25, 26].
Adults may sometimes appear to be normal morphologically, but there are mite effects on adult bee behavior.
The behaviors we scored were biting the mite, unsuccessful attempt to groom, and successful grooming.
We evaluated the extent of Africanization through three typical Africanized traits: wing size, defensive behavior, and resistance to Varroa destructor mites.
Nevertheless, selection experiments in the (sexual) spider mite Tetranychus urticae have revealed that plastic sex-allocation behavior can decay rapidly (within 54 generations) under situations of relaxed selection (Macke et al., 2011).
Grooming can remove ectoparasites, and hygienic behavior can reduce levels of brood diseases and depress Varroa mite populations (mites feed on developing pupae).
