Abstract
The present investigation was carried out to evaluate the effects of different miticides, fluvalinate, Amitraz, oxalic acid, formic acid and thymol on honeybee drones. Drones were measured for body weight, length, width of fore wing and number of sperms in one seminal vesicle. Drones treated with fluvalinate, Amitraz, Oxalic acid and thymol had significantly less weight and less wing length than the control group. The least values of body weight and wing length observed in colonies treated with fluvalinate recorded 0.186gm and 10.615mm respectively, while the highest values of body weight was 0.205gm and wing length was 10.957mm observed with formic acid. Wing width in drones exposed to fluvalinate, Amitraz and oxalic acid were significantly lower than control. Drones exposed to fluvalinate and Ammitraz had significantly lower sperm count than drones of control recorded 4.33×106, 3.55×106 and 5.39×106 respectively. A positive correlation between sperm number and wing size was recorded
