Effect of Varroa destructor on different haemocyte count, total haemolymph protein on larvae, pupae and adults of Apis mellifera drones

ABSTRACT

The effect of infestation with Varroa destructor Oud. [Acarina Varroidae] on the heamolymph of the different stages in honey bee drons were studied. It decreased the total haemocyte count [THC] by 47.4%, 13.04% and 65% for infested larvae, pupae and adults, respectively. Differential haemocyte count [DHC], haemocyte surface area, corpora allata surface area [CA] and total haemolymph protein [THP] were decreased also due to infestation with varroa mite
