“…In addition, in the second experimental year 2016 the highest mean of all brood for natural swarming colonies was 302.24 inch 2 / colony in the summer season and the same for dividing colonies the highest mean area of all brood was 212.47 inch 2 / colony in the summer season. That means that the highest brood areas were in summer in both types of colonies (natural swarm and artificial swarm) also in both of the study years (2015 and 2016), and that was normal for all colonies due to the summer season is the activation season for the honey bee colonies, and the rate of colonies individuals increased always in summer season as illustrated by (El-Hosainy et al, 2017) that the highest rate of brood activity was in May and the highest number of bees was investigated in June and July. That was recorded by that the highest brood production was in summer followed by spring, autumn, and winter seasons.…”

Honey bee swarming is a crucial behavior for the population reproduction of honey bee colonies in early spring and autumn. It is well known that the honey bee reproductive swarming always shows a genetic diversity among the swarmed individuals of specific genes. This type of genetic diversity always occurs for the individuals that naturally swarmed. Twelve honey bee nuclei were used; six from natural and the other six from artificial swarming. For studying the biological activity parameters including; honey, pollen, and brood. Moreover, the hygienic behavior test, queen weight, queen rearing, and ovarioles number were recorded for two years. Moreover, two different molecular techniques were used such as specific PCR and RAPD PCR. The molecular part helps in understanding the genetic diversity developed between swarm's individuals and those artificial ones. Concerning the biological activities; the results illustrated that the swarm nuclei had a highly significant difference compared with the artificial one in the first year, whenever, non-significant differences were observed between the two examined swarms in the second year. Furthermore, molecular differences were obtained assuming these differences back to the corresponding swarming related genes which mostly control some of the defense genes of hygienic and grooming behavior. These results revealed the presence of a tide-relationship between the bees' immune system and their genetic profiles. Thus, recommend leaving the colonies to prepare for a swarming to enhance their production ability and hygienic behavior after distributing the hunting hives in the apiaries to avoid missing colonies.

“…The best seasons to divide, the best colonies to divide, types of queens, and how queens are introduced to new divisions have been studied by El-Hosainy et al (2017); Sheikh (2019). Hygiene behavior testing for honey bees Apis mellifera L. includes inspecting, opening caps, and removing sick or dead bees from the colony.…”
