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...

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...

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...

The aim of the study was to estimate the impact of antibiotic doxycycline on the spring development of the bee colonies, worker bees’ bodies chemical composition, development of hypopharyngeal glands and some physicochemical parameters of honey. The experiment was conducted during the spring stimulating feeding at apiary of Research Center of Stockbreeding and Agriculture, Smolyan, Bulgaria. Tw...

Artificial Bee Colony algorithm is an optimization algorithm based on the intelligent behavior of honey bee swarm. This paper presents Bee Swarm Optimization intended to introduce chaotic sequences and psychology factor of emotion into the algorithm. We define two emotions Bees could have, positive and negative, and correspond to two reaction to perception respectively. For avoiding premature c...

abstract: mostly honey bee consumes pollen as fermented and fermentation improves foods biological value in some cases.  in this study we evaluate the nutritional effects of fermented diets on honey bee body protein and brood rearing in colonies. this experiment conducted on honey bee colonies with different diets in a completely randomized design with 6 treatments and 7 replicates for 50 days....

Bees, as the main pollinators of food crops, represent a critical natural resource which needs to be carefully exploited and managed. In recent years, however, destruction of bee's native habitats, infestations, and displacements of native bees by alien bee species have reduced and disturbed bee populations and this is already having considerable impact on global agriculture. A further concurre...

Bee product mugwort is identified as being at the origin of allergic accidents but the biological potency of Artemisia contained in bee pollen is not well known. In this experiment, Artemisia mass was identified in bee pollen mass and after having calculated the proportion of Artemisia using the bee pollen melissopalynology spectrum. Skin reactivity to Artemisia was assessed by measuring wheal ...
