Honey Bee Photoresponse as Influenced by Age. Part II: Drones and Queens

Abstract
Drone and queen honey bees, Apis mellifera L., were tested to ascertain their photoresponse at different ages. Drones, in groups of 40, were each tested 10 times in succession for their photoresponse. Drones ranging in ago from 1 to 2 days postemergence and flight age responded photopositively in highly significant numbers. Newly emerged drones were immobile, and therefore it was not possible to test their response to light. Queens up to 2 days after emergence were photonegative. During the day(s) approximating their mating flight, they became photopositive. After they had mated and started to lay eggs, they again became photonegative. All of these results were found to be highly significant.
