In this study, the larvae acceptance rate and royal jelly yield in honeybee (Apis mellifera L.) colonies supplemented with different industrial sugars at locations were determined. For purpose, feeding groups (1. Sucrose group, 2. Glucose 3. Bee feed syrup 4. Control group) Battalgazi, Doğanşehir) formed. queenless that produce jelly, order to sustain 5-15 day-old young feeder worker bees, two ...

In this study, it was investigated ejaculation ability and semen quality of drones, according to feeding with pollen in different periods.
 the first step 16 %, 32 47 63 79 100 % periods applied for investigating effect on ability, drones investigated.
 While investigation these period effects “0-1”, bonded, unbounded knapsack optimization problems used. After most effective determine...

The honey bee is among most important pollinators threatened by environmental pollution, pest control and potentially, by products of nanotechnologies. The aim of the current study was an analysis of the neurotoxic potential of ingested zinc oxide nanomaterials (ZnO NMs) or zinc ions (Zn(2+)) on honey bees. We analysed a variety of biomarkers, including metabolic impairment, feeding rate, and s...

Few areas of the world have western honey bee (Apis mellifera) colonies that are free of invasive parasites Nosema ceranae (fungi) and Varroa destructor (mites). Particularly detrimental is V. destructor; in addition to feeding on host haemolymph, these mites are important vectors of several viruses that are further implicated as contributors to honey bee mortality around the world. Thus, the b...

Stingless bees of the species Trigona spinipes (Fabricius 1793) use their saliva to lay scent trails communicating the location of profitable food sources. Extracts of the cephalic labial glands of the salivary system (not the mandibular glands, however) contain a large amount (approx. 74%) of octyl octanoate. This ester is also found on the scent-marked substrates at the feeding site. We demon...

Background: Due to its nutrient content, a variety of spoilage microorganisms can grow in bee pollen, especially when handling practices are not appropriate. So, this survey was designed to assess the physicochemical and microbiological properties of bee pollen collected from Bulgaria. Methods: In June 2014, 13 fresh and 19 dried bee pollen samples were collected from Bulgaria. Water activity ...

The potency of various bee antigens including bee venom, several whole bee body extracts and fractions of bee venom was studied using the RAST inhibition method. As compared to whole bee body extract, bee venom was a much more potent inhibitor of both bee venom and whole body RAST, suggesting that venom has a greater capacity to bind specific bee IgE antibodies. Whole body extracts also varied ...
