Journal of Hymenoptera Research 68: 85–101. https://doi.org/10.3897/jhr.68.29678 Abstract Honey production gains are needed to deal with high demand in Saudi Arabia. The honey bee races are facing stressful hot-arid weather conditions that can affect different aspects of physiology and behav- ior. The hypopharyngeal glands (HPGs) of honey bees have prominent roles in various social behav- iors through their secretions. -

A Saliva Protein of Varroa Mites Contributes to the Toxicity Toward Apis Cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A
www.nature.com/scientificreports OPEN A Saliva Protein of Varroa Mites Contributes to the Toxicity toward Apis cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A. mellifera Published: xx xx xxxx Yi Zhang & Richou Han Varroa destructor mites express strong avoidance of the Apis cerana worker brood in the feld. The molecular mechanism for this phenomenon remains unknown. We identifed a Varroa toxic protein (VTP), which exhibited toxic activity toward A. cerana worker larvae, in the saliva of these mites, and expressed VTP in an Escherichia coli system. We further demonstrated that recombinant VTP killed A. cerana worker larvae and pupae in the absence of deformed-wing virus (DWV) but was not toxic to A. cerana worker adults and drones. The recombinant VTP was safe for A. mellifera individuals, but resulted in elevated DWV titers and the subsequent development of deformed-wing adults. RNAi- mediated suppression of vtp gene expression in the mites partially protected A. cerana larvae. We propose a modifed mechanism for Varroa mite avoidance of worker brood, due to mutual destruction stress, including the worker larvae blocking Varroa mite reproduction and Varroa mites killing worker larvae by the saliva toxin. The discovery of VTP should provide a better understanding of Varroa pathogenesis, facilitate host-parasite mechanism research and allow the development of efective methods to control these harmful mites. Varroa destructor Anderson & Trueman (Acari: Varroidae) was originally identifed as an ectoparasite of the Asian honeybee Apis cerana. Before the year 2000, V. destructor was miscalled V. jacobsoni. In fact, these two species are diferent in body shape, cytochrome oxidase (CO-I) gene sequence, and virulence to honey bees1. -

But in the hours spent away from our hives, thousands of tiny miracles are happening everyday. Within the hexagonal wax cells little lives are hatching out and joining the hive family. The whole process from egg to adult worker bee takes around 18 days. During the laying season late spring to summer the Queen bee is capable of laying over eggs per day. Her worker bees help direct her to the best prepared comb and she lays a single egg in each hexagon shaped cell. The size of the cell prepared determines the type of egg she lays. If the worker bees have prepared a worker size cell, she Life Cycles: Egg to Bee lay a fertilized egg. This egg will produce a female worker bee. If the worker bees have prepared a slightly larger cell, the queen will recognize this as a drone cell and lay an unfertilized egg. This will produce a male drone bee. It is the workers and not the queen that determine the ratio of workers to drones within the hive. In three days the egg hatches and a larva emerges. It looks very similar to a small maggot. -
Queen Morphometric and Reproductive Characters of Apis Mellifera Jemenitica, a Native Honey Bee to Saudi Arabia
Bulletin of Insectology 66 (2): 239-244, 2013 ISSN 1721-8861 Queen morphometric and reproductive characters of Apis mellifera jemenitica, a native honey bee to Saudi Arabia Abdulaziz S. ALQARNI, Hassan M. BALHARETH, Ayman A. OWAYSS College of Food and Agriculture Sciences, King Saud University, Riyadh, Saudi Arabia Abstract Ten traits of morphological characters and reproductive organs of newly emerged virgin queens of native and imported honey bee races, Apis mellifera jemenitica Ruttner (AMJ) and Apis mellifera carnica Pollman (AMC), were measured. The results for the comparison between the AMC and AMJ queens showed significant differences in most cases. The virgin AMC queens showed significantly increased body weight (165.9 ± 9.8 mg) over that of AMJ (137.8 ± 7.9 mg) in the two seasons of the study. In addi- tion, the AMC queens had significantly higher values than those of AMJ for all tested morphological traits, including the head capsule (2.61 × 2.44 mm versus 2.45 × 2.23 mm), right mandible (1.29 × 0.38 mm versus 1.18 × 0.37 mm), forewing (9.39 × 3.10 mm versus 9.17 × 3.00 mm), and the length of the 3rd + 4th abdominal tergites (5.95 mm versus 5.57 mm), respectively. The num- ber of ovarioles of the right ovary in the AMC queens was significantly higher (157.0 ± 14.9) than that (146.6 ± 13.9) of AMJ. The diameters of the spermathecae were 1.253 and 1.230 for AMC and AMJ, respectively, with significant differences between the two races in the 2nd season of the study. -

Laboratory tests were carried out at the Department of Apiculture at UWM Olsztyn, using gas sensors installed in two twin prototype multi-sensor detectors. The study aimed to compare the responses of sensors to the odor of old worker bees (3–6 weeks old), young ones (0–1 days old), and those from long-term queenless colonies. From the experimental colonies, 10 samples of 100 workers were taken for each group and placed successively in the research chambers for the duration of the study. Old workers came from outer nest combs, young workers from hatching out brood in an incubator, and laying worker bees from long-term queenless colonies from brood combs (with laying worker bee’s eggs, humped brood, and drones). Each probe was measured for 10 min, and then immediately for another 10 min ambient air was given to regenerate sensors. -
Colony Collapse Disorder in Relation to Human-Produced Toxins: What's
Colony Collapse Disorder in relation to human-produced toxins: What’s the buzz all about? Available at: http://www.sawyoo.com/postpic/2013/09/honey-bee-hives_77452.jpg Last accessed: 17/04/2017 Abstract: p2 Introduction: p3 Insecticides: p5 Herbicides & fungicides: p7 Miticides & other preventative measures: p9 “Inactive” ingredients: p10 Synergies between pesticides: p11 Conclusions: p12 Discussion: p12 References: p14 1 Abstract In recent years, the global population of pollinating animals has been in decline. The honey bee in particular is one of the most important and well known pollinators and is no exception.The Western honey bee Apis mellifera, the most globally spread honey bee species suffers from one problem in particular. Colony Collapse Disorder (CCD), which causes the almost all the worker bees to abandon a seemingly healthy and food rich hive during the winter. One possible explanation for this disorder is that it is because of the several human produced toxins, such as insecticides, herbicides, fungicides and miticides. So the main question is: Are human-produced toxins the primary cause of CCD? It seems that insecticides and, in particular, neonicotinoid insecticides caused increased mortality and even recreated CCD-like symptoms by feeding the bees with neonicotinoids. Herbicides seem relatively safe for bees, though they do indirectly reduce the pollen diversity, which can cause the hive to suffer from malnutrition. Fungicides are more dangerous, causing several sublethal effects, including a reduced immune response and changing the bacterial gut community. The levels of one fungicide in particular, chlorothalonil, tends to be high in hives. Miticides levels tend to be high in treated hives and can cause result in bees having a reduced lifespan. -

The best known honey bee is the Western honey bee which has been domesticated for honey production and crop pollination. Honey bees represent only a small fraction of the roughly 20,000 known species of bees.[2] Some other types of related bees produce and store honey, including the stingless honey bees, but only members of the genus Apis are true honey bees.

In the current study we assessed the natural nest volume, workers brood cell dimensions and bee space of the race through measuring their dimensions from naturally built combs in log hives. The optimum box hive volume and surface area requirement were assessed by keeping colonies at different volumes of frame hives with four replications each and monitored for a period of one year. The average occupied nest volume and comb surface area of the race in log hives were 12.28 ± 5.98 l and 8017.2 ± 3110.60 cm2 respectively which are significantly smaller than other A. mellifera races. The worker brood cells width and depth of the race were 4.07 ± 0.17 mm and 9.39 ± 0.42 mm respectively and the race builds an average of 262.5 more worker brood cells/dm2 than is built on embossed foundation sheets. -
