Seasonal changes in body weight and water content of female Varroa jacobsoni






Doklady Akademii Nauk Ukrainskoi SSR, B (8): 58-60

Seasonal changes in body weight and water content of female Varroa jacobsoni

Studies of body mass and water content in female V. jacobsoni on overwintering honeybees showed that in autumn there was a large decrease in water content, an increase in dry matter and a practically unchanged fresh body weight. When honeybee brood rearing started after wintering, the total body weight and water content of the mites started to increase, with a corresponding reduction in dry matter.
