“…Statistical analysis indicated that there is a correlation between brood and pollen grains by 48.6% with LSD = 37.42 and P = 0.000**. There was a direct relationship between pollen grains production and brood production in the Airland region (Masry and Abdelaal, 2016).…”

“…There is a correlation between sealed brood and stored honey 55% agreed with (Tahmasbi et al, 2015) showed a significant correlation between bee population and honey production. In addition, (Masry and Abdelaal, 2016)showed that; there was a significant correlation between stored bee honey, pollen grains, brood, and the weather under the new Borg El-Arab region and the bee population increased from spring to winter then beekeepers can save their colonies in winter to manage the next season by easy way. (Bouga et al 2007) stated that honey yield affected the bee population size, and the colonies had many workers store a big amount of honey.…”

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 healthy and activity of honeybees became a worldwide concern, as presented over the last decades by decline its populations ( Lee et al, 2015 , Traynor et al, 2016 ). Factors caused this decline include a combination of environmental conditions, infectious diseases, pesticides and lack of flowering plants and habitat as well ( Le Conte and Navajas, 2008 , Pârvu et al, 2013 , Goulson et al, 2015 , Masry and Abdelaal, 2016 ). This insect is menaced by numerous pathogens, including bacteria, fungi, viruses, and protozoa.…”

American foulbrood (AFB) and European foulbrood (EFB) are the two major bacterial diseases affecting honeybees, leading to a decrease in viability of the hive, decreasing honey production, and resulting in significant economic losses to beekeepers. Due to the inefficiency and/or low efficacy of some antibiotics, researches with nanotechnology represent, possibly, new therapeutic strategies. Nanostructure drugs have presented some advantagesover the conventional medicines, such as slow, gradual and controlled release, increased bioavailability, and reduced side-effects. In this study, different infected larvae were collected from two apiaries; the combs that had symptoms of American and European foulbrood were isolated. In vitro antimicrobial activity of camphor tree silver nano-particles against foulbrood diseases were characterized using UV–Vis spectrophotometry and scanning electron microscope (SEM) that proves the formation of silver nanoparticles with size range 160–660 nm. The antimicrobial activity of the silver nanoparticles was tested using agar diffusion assay and proved their ability to effectively cease the pathogenic bacterial growth in both AFB and EFB. DGGE-PCR technique has been applied for the identification of un-common bacterial infections honeybees depending on 16S rRNA amplification from their total extracted DNA and has been identified as Serratia marcescens (TES), deposited in GenBank with a new accession number (MT240613). The results were confirmed strain has been detected by DGGE-PCR analysis causing uniquely infected brood that was attacked by the American Foulbrood It could be concluded that greenly synthesized silver nanoparticles is projected to be used as effective treatment for honeybee bacterial diseases. These material need more investigations under field conditions and study the possibility of its residues in honeybee products such as honey, and beeswax.
