Field and laboratory assessment to hygienic behavior of Carniolan Honey Bees with studying impacts of oxalic acid on grooming behavior
Abstract :In this study, the hygienic behavior of Tatranka
and Hontianka Carniolan honey bees of Slovakia and Carniolan bee hybrids of
Egypt was studied under field conditions. Also, a new laboratory method to
evaluate the hygienic behavior was done. Moreover, the influence of oxalic acid
treatments on the grooming behavior of the Carniolan bees was investigated. The
results showed that the studied colonies exhibited hygienic trend against dead
brood with percent more than 80%, and the best of them was Hontianka. The
laboratory method showed that the caged bees were able to exhibit their hygienic
trend by uncapping and removing dead brood from the cells. The results suggest
that hygienic bees should clean at least 50% of the cells in the laboratory
test. Oxalic acid treatments showed
efficacy against Varroa mites and caused increase in the percents of the fallen
mites. However, oxalic treatments did not enhance the grooming behavior or even
change the attitude of bees against Varroa mites during grooming. The results
of this study are essential towards developing naturally resistance Carniolan
bees to Varroa mites. The new laboratory method can be considered as a keystone
towards easier method to evaluate the hygienic behavior
