Fatalities among avian species due to multiple bee stings are rare. Sixteen pigeons on a farm in Bangladesh each suffered multiple bee stings. Ten of the pigeons died before treatment, 5 (4–11 stings) died within 12 hr after treatment, and 1 pigeon (only 3 stings) survived. Body temperature, heart rate, respiratory rate, hematocrit, hemoglobin, erythrocytes, thrombocytes, MCV, MCH and MCHC decr...

The reasons for the decline are currently not clear. However, some studies have linked the reduction in bee numbers to a widely-used class of pesticides, neonicotinoids, that have been broadly administered in large-scale crop production since the mid 1990’s – the same time that mass bee disappearances started to be reported 2. These nicotine-like chemicals, which include three key neonicotinoid...

Pollinators are essential to Pacific Northwest agriculture Commercially managed honey bees pol-­ linate a variety of crops in the Pacific North-­ west, including tree fruits, berries, cucurbits, and crops grown for seed. This activity is economically significant. In 2004, the value of bee-­pollinated crops in the region was approxi-­ mately $1.7 billion (Burgett, 2004). Nation-­ ally, the value...

Investigation of the single plant source bee glue type originating from Southern Australia resulted in the isolation and structure elucidation of major serrulatane diterpenes, novel 7,8,18-trihydroxyserrulat-14-ene (1), along with its oxidized product, 5,18-epoxyserrulat-14-en-7,8-dione (3) and known (18RS)-5,18-epoxyserrulat-14-en-8,18-diol (2). Exploration into the botanical origin revealed M...

Basal energy expenditure (BEE) was determined in 291 pregnant women, age 20-35 years, using Benedict Roth Metabolism Apparatus. A control study was undertaken in 38 non pregnant women during both follicular and luteal phases of menstrual cycle respectively. The mean +/- SD of BEE were found to be 34.04 +/- 3.05, 35.85 +/- 2.60 and 39.69 +/- 2.75 Kcal/m2/hr during first, second and third trimest...

For two consecutive years in Abbi, Delta State of Niger-Delta of Nigeria one, two and three beehives were integrated in oil palm plantation to determine optimum productivity of the oil-palm honey bee farming system. The fresh fruit bunch (economic yield) of the oil palm was statistically similar at 0, 1, 2 and 3 bee hive(s) per hectare. The honey yield were statistically similar for each bee hi...

In the United States, policy initiatives aimed at increasing sources of renewable energy are advancing bioenergy production, especially in the Midwest region, where agricultural landscapes dominate. While policy directives are focused on renewable fuel production, biodiversity and ecosystem services will be impacted by the land-use changes required to meet production targets. Using data from fi...

This study investigated possible growth-inhibiting effects of bee venom applied alone or in combination with a cytotoxic drug bleomycin on HeLa and V79 cells in vitro based on clone formation, cell counting, and apoptosis. Melittin, the key component of bee venom, is a potent inhibitor of calmodulin activity, and also a potent inhibitor cell growth and clonogenicity. Intracellular accumulation ...
