Honey bees are critical for agricultural crops pollination. However, many countries have reported high annual colony losses caused by multiple possible factors. Diseases, including those caused by viruses of honey bees, are a significant cause of colony losses. However, nothing is known about the occurrence of viruses of honey bees in Palestinian honey bees. Therefore, eighty colonies from eight apiaries in Bethlehem and Hebron governorates were randomly selected and screened for the presence of 15 viruses of honey bees via quantitative PCR technique. Ten viruses were detected among which the Black Queen Cell virus (BQCV) was the most prevalent (96 % of all colonies) followed by Deformed Wing viruses (DWV) A (77%) and B (72%) and a new emerging virus, the Big Sioux River virus (BSRV, 70%). Other viruses ( Apis mellifera filamentous virus (AmFV), Lake Sinai virus 1 (LSV-1), Acute Bee Paralysis virus (ABPV), Sacbrood virus (SBV), Israeli Acute Paralysis virus (IAPV), and Chronic Bee Paralysis virus (CBPV) had lower colony prevalences ranging between 9 - 29%. The study showed that most of the viruses were present in all apiaries, and multiple virus infections per colony were common in all colonies. Our findings fill a knowledge gap about the prevalence of viruses of honey bees in Palestine, which could assist in protecting the Palestinian beekeeping industry.

This research aims to perform outcrossing mating on 60 beehives with virgin queens, followed by an investigation into the impact of hybrid vigor on both spring brood rearing activity and honey production. This outcrossing experiment was conducted with two beekeepers hailing from Tukra and Jirdinah in Lybia. The 60 beehives were divided into four groups to facilitate the investigation, with measurements taken on spring building and honey production. It was observed that bee colonies with outcrossing mating had significant increase in brood rearing activity compared to colonies that did not receive the outcrossing treatment. The results showed that colonies with outcrossing mating increased in hybrid vigor of 32.78% in spring brood rearing activity and 23.61% in honey production. The outcomes of this investigation have bestowed upon male honey bees a heightened level of power during the mating periods, allowing for the manipulation of mating through the alteration of the distance between colonies. This research ultimately provides profound insights into the complex mechanisms of honey bee mating and carries significant implications for beekeeping. It furthers our understanding of male honey bees' vital role in reproducing honey bees. It highlights the importance of manipulating the distance between colonies to optimize the mating process. This study also underscores the need for beekeepers to prioritize the selection of honey bees with desirable traits, as this will produce high quality offspring with improved characteristics.

This research was conducted to evaluate the biological effect (bees hybrids), environmental (collection season) and technical method (location of collecting plate within the hive) on the amounts of harvested dry venom using electrical chock method in Giza, Egypt. Ninety-six honeybee colonies in homogenous strength were selected from Carniolan and Italian hybrids (48 colonies each). Each hybrid group was equally divided into six subgroups, which were distributed from March to August. The venom was collected only once from each subgroup. The results showed that the upper frame position of collecting plate was the best with significant amounts of venom (29.4 mg/col.), higher than putting the plate beneath the frames (14.6 mg/col.). The colonies of Carniolan hybrid produced significant quantity of dry venom (26.5 mg /col.) compared with Italian hybrids (17.6 mg /col.). Also, the mean amount of harvested venom during spring season was significantly higher (23.1 mg/col.) than that produced during summer season (20.8 mg/col.). A pronounced quantity of dry venom could be monthly produce throughout the period from March to August, ranging from 21.4 to 34.1 mg/col., with the upper frames collecting plate.

Honey bee diseases and pests caused dramatic losses of Tunisian honey bee colonies during the past years. This research aimed to evaluate of beekeepers’ perceptions on bee diseases and pests, and current management practices via interview method of 80 beekeepers in the North of Tunisia. The data were analyzed using descriptive analysis. Most of the beekeepers reported that Varroosis was the most dangerous pest (97.5%), followed by Foulbrood (19%). Moreover, "moth" butterfly (heteroecious) was the most cited pest (15.2%). Diseases and pest reports were significantly correlated with the educational level of the beekeepers, their training, route to beekeeping (heritage) and number of bee hives. The treatment of diseases was carried out twice a year by most beekeepers (70.7%), once (25.3%) or three times (4%) per year, mainly in winter (62.1%) and autumn (37.9%). The used sanitary products by the respondents were Apivar ® (63.9%), Apistan ® (35.1%), Apiguard ® (35.1%), a mixture of garlic and petrolatum (6.5%), or a mixture of garlic and thyme essential oil (1.3%), accordingly to the disease nature (p<0.05). The treatment type was significantly related to beekeepers' age and education, number of bee hives and the disease nature (p<0.05), whereas significant correlations of numbers and season of treatment applications were found with beekeepers’ age, honey laboratory analysis and disease nature (p<0.05). Finally, 98% of beekeepers have implemented preventive prophylactic measures before honey harvesting based on apiary hygiene control, which confirms that the beekeepers are aware of the importance of sanitation.

This study was conducted to evaluate the response of common bean ( Phaseolus vulgaris L.), Paulista cv., to silver nanoparticles (Ag + NPs) levels i.e., 0, 50, 100, and 150 ppm as foliar spray or soil drenching. The results showed that superiority values of plant vegetative growth characteristics (plant length, number of branches/plants, and plant fresh weight) as well as leaf chlorophyll content, total green pods yield and pod traits (pod length, pod diameter, and pod fresh weight) were pronounced at 50 ppm foliar spray treatment followed by 100 ppm concentrates as soil drenching. However, silver nanoparticles at the high dose of 150 pp, particularly foliar spray, obviously causes decreases in plant vegetative characteristics, total green pods yield (ton/fed) and pod chemical contents of protein and carbohydrates. It can be concluded that silver nanoparticles can be used in low concentrations to improve the growth, productivity, and pod chemical contents of Phaseolus vulgaris plants.
