The effect of capped brood incubation temperature on the reproductive value of honey bee (Apis mellifera) drones was examined. Drones incubated at 32°C had larger reproductive organs and a higher percentage of live spermatozoa. On the other hand drones incubated at 35°C were more likely to have everted copulatory apparatus and they ejaculated a larger volume of semen. To collect a semen dose of 8 μl, on average 16.2 drones incubated at lower temperature were required, but 10.9 drones incubated at higher temperature produced the same amount.
