One potential method to increase honey bee, Apis mellifera L., pollination in alfalfa, Medicago sativa L., seed fields is to develop populations that emanate greater quantities of honey bee attractive floral volatiles. Our study was designed to deter

Seven staining techniques were modified and tested for differentially staining the live and the dead sperm cells for the honey bee (Apis mellifera L.). The eosin Y staining method was found to be a simple technique by which the live cells stain bluis

A new supravital staining technique is described for honey bee, Apis mellifera L., spermatozoa using the fluorochromes, propidium iodide and Hoechst 33342 (H342), a bis-benzimidazole derivative. Propidium iodide binds to the DNA of sperm which lack m

The structure, distribution, and type of sensory hairs on the palptarsus of female Varroa jacobsoni Oudemans were examined by scanning electron and phase contrast microscopy. The two large, peg-like setae with apical pores are chemoreceptor sensilla

Within 7 d, small honey bee ( Apis mellifera L.) colonies that consumed low levels of methamidophos in sugar syrup lost more eggs and larvae than control colonies, without conspicuous loss of adult worker bees. Youngest brood and brood at the transit

In an attempt to determine the effect of feeding on Apis mellifera L. populations and the economic value of feeding colonies for spring production of package-bees, a feeding experiment was conducted to evaluate the effect of feeding time and feeding

SummaryLactase (β-galactosidase) was found in the midguts of normal adult worker honeybees and in those fed with lactose. Sephadex G-200 chromatograms of midguts of both groups showed two enzyme activity peaks, molecular weights of lactase being det
