Abstract (sommario):

ABSTRACTThe effect sublethal concentrations (¼ and ½ of LC50 at 96 hrs.) of biopesticide neem oil – 25 EC was studied on the forager bees (25 days old worker bees) of Italian honeybee Apis mellifera L. The results indicated that there were no significant alteration in total amino acid contents in forager bees at either sublethal concentration level-1(¼ of LC50 at 96 hrs) or concentration-2 (½ of LC50 at 96 hrs.) of neem oil treated bees over control bees. Although field experiments are inevitable for further confirmations of lethality of neem oil on honeybees.

Abstract (sommario):

Pollen is essential to the development of honey bees. The nutrients in bee pollen vary greatly among plant species. Here, we analyzed the differences in the amino acid compositions of pear (Pyrus bretschneideri), rape (Brassica napus), and apricot (Armeniaca sibirica) pollens and investigated the variation in hemolymph metabolites and metabolic pathways through untargeted metabolomics in caged adult bees at days 7 and 14. The results showed that the levels of five essential amino acids (isoleucine, phenylalanine, lysine, methionine, and histidine) were the highest in pear pollen, and the level

Abstract (sommario):

Honey bee broods (larvae and pupae) can be consumed as human food, offering a rich nutritional value. Therefore, the objective of this work was to present an overview of the nutritional value of the honey bee brood and its gastronomic potential. The results indicated that honey bee broods are rich in protein (including essential amino acids), fat (essentially saturated and monounsaturated fatty acids), carbohydrates, vitamin C and those of the B complex, and minerals such as potassium, magnesium, calcium, and phosphorous. The results further highlight some variability according to the stage of

Abstract (sommario):

Summary. A trial was conducted to measure the impact of honeybees (Apis mellifera L.) on faba bean (Vicia faba L.) yields and to determine the value of the crop to honeybees. The seed yield in cages with bees was 25% higher than in those without bees. The pollen harvested by honey bees from the faba beans met their nutritional requirements for protein and amino acids but there was no detectable nectar crop gathered from the faba beans. Thus, there seems to be a strong case for using managed honey bees to improve pollination and hence yields of Australian faba beans where feral bee populations

The queen bee is a central and pivotal figure within the colony, serving as the sole fertile female responsible for its reproduction. The queen possesses an open circulatory system, with her ovaries immersed in hemolymph. A continuous and intricate transportation and interchange of substances exist between the ovaries and hemolymph of queen bees. To determine the characteristic metabolites in the hemolymph and ovary, as well as understand how their rapid metabolism contributes to the process of egg-laying by queens, we reared Apis mellifera queens from three different age groups: newly emerged

Honey bee colonies have a yearly cycle that is supported nutritionally by the seasonal progression of flowering plants. In the spring, colonies grow by rearing brood, but in the fall, brood rearing declines in preparation for overwintering. Depending on where colonies are located, the yearly cycle can differ especially in overwintering activities. In temperate climates of Europe and North America, colonies reduce or end brood rearing in the fall while in warmer climates bees can rear brood and forage throughout the year.

Abstract (sommario):

Worldwide, honey bees are increasingly faced with periods of pollen scarcity, which can lead to nutritional deficiencies, especially of proteins and amino acids. These are essential for the proper functioning of the single organism and the colony. To understand how bees react to protein deficiency, under controlled conditions, we studied the effect of pollen deficiency on the main physiological parameters in two subspecies endemic of Algeria, Apis mellifera intermissa and Apismellifera sahariensis. Emerging workers of both subspecies were reared with two diets: one was pollen-fed, whereas the

Abstract (sommario):

Tropilaelaps infestation of Apis mellifera pupa caused reduction in total protein concentration of the infested pupa. This may be due to protein feeding by mite. The additional protein fractions observed by SDS-PAGE and the difference in the nature of free amino acids suggested synthesis of newer proteins perhaps related to the stress response of the host. This opinion is strengthened by the increase in concentration of RNA ( 184.580±36.987 in non-infested pupa and 293.402±50.329 in infested pups) observed in the present study which was responsible for increased transcription of genes encoding

Abstract (sommario):

An important area of physiology of the honeybee (Apis mellifera) is chemical communication between individuals and castes in the swarm, which maintains its integrity and function. The highly complex social organization of honeybees is mediated through pheromones. Releaser pheromones cause rapid changes in the behaviour of the recipient, while primer pheromones have relatively slow and long-term effects on the physiology and behaviour of the recipient. Queen retinue pheromone (QRP) is a blend of the nine compounds (9-oxo-(E)-2-decenoic acid, (R)- and (S)-9-hydroxy-(E)-2-decenoic acid, methyl p-

Abstract The European honey bee (Apis mellifera L.) is known to be affected by such stress factors as pathogen load, poor nutrition and depressed immunity. Nosema ceranae is one of the main parasites that affect colony populations. The relationship between the stress factors and honey bee-bacteria symbiosis appears as an alternative to enhance bee health. The aim of this study was to evaluate the effect of the oral administration of bacterial metabolites produced by Lactobacillus johnsonii AJ5 on nutritional parameters, the N. ceranae development and the performance of A. mellifera colonies.

Moreover, the E. coli-expressed and -purified cystatin was injected into the white-eyed honeybee pupae, and its effects on the survival, the weight of the new
