Wild bee conservation is regarded as essential for sustainable production of pollinator-dependent crops, yet little is known about the effects on wild bee communities of typical insect pest management programs used postbloom. We developed an insecticide program risk (IPR) index to quantify the relative risk to wild bees of insecticide programs applied to blueberry fields. This was used to deter...

In the present study, the effects of low (10 ng/bee) and high (100 ng/bee) doses of acetamiprid and deltamethrin insecticides on multi-trial learning and retrieval were evaluated in the honey bee Apis mellifera. After oral application, acetamiprid and deltamethrin at the concentrations used were not able to impair learning sessions. When the retention tests were performed 1 h, 6 h, and 24 h aft...

Bee sting in most situations is life threatening. Spectrum of bee sting ranges from mild local reaction to death. The literature regarding the bee sting disease from India is sparse. The rare manifestations of the disease include encephalitis, polyneuritis, myocardial infarction, pulmonary edema, bleeding manifestations, and renal failure. Bee sting infections are rare and no field studies have...

Pathogens and pollutants, such as pesticides, are potential stressors to all living organisms, including honey bees. Herbicides fungicides among the most prevalent pesticides in beehive matrices, their interaction with Nosema ceranae is not well understood. In this study, interactions between N. ceranae, herbicide glyphosate fungicide difenoconazole were studied under combined sequential overla...

The artificial bee colony (ABC) algorithm is a swarm-based metaheuristic optimization technique, developed by inspiring foraging and dance behaviors of honey bee colonies. ABC consists of four phases named as initialization, employed bee, onlooker bee and scout bee. The employed bees try to improve their solution in employed bees phase. If an employed bee cannot improve self-solution in a certa...

Honey bees collect nectar and pollen to fulfill their nutritional demands. In particular, can influence longevity, the development of hypopharyngeal glands, immune-competence bees. Pollen also mitigate deleterious effects caused by parasitic mite Varroa destructor related deformed wing virus (DWV) infections. It has been shown that V. accelerates physiological behavioral maturation honey influe...

Biodiversity is important for many ecosystem processes. Global declines in pollinator diversity and abundance have been recognized, raising concerns about a pollination crisis of crops and wild plants. However, experimental evidence for effects of pollinator species diversity on plant reproduction is extremely scarce. We established communities with 1-5 bee species to test how seed production o...

  Honey bee sting is used in some societies as a treatment of inflammation in joint diseases such as arthritis. To investigate the effect of honey bee venom in reducing inflammation, we selected 30 male Wister rats which were divided in to 6 groups. Except group 1, all remaining groups received 0.5 ml of complete Freund’s adjuvant to induce arthritis. After 9 days, all animals that received adj...
