Інтродукція Рослин, 2003 Species of Amaranthus L. genus are anemophilous plants, but we observed active attendance of honeybee (Apis mellifera L.) to A. paniculatus L., A. caudatus L., A. hypochondriacus L., A. mantegazzianus Passer, introduced into Ukraine. We discovered pollen

Lipophorin of the larval honeybee, Apis mellifera L.
Journal of Lipid Research, 1985 Most insects have a major lipoprotein species in the blood (hemolymph) that serves to transport fat from the midgut to the storage depots in fat body cells and from the fat body to peripheral tissues. The generic name lipophorin is used for this lipoprotein.

The honeybees (Apis mellifera L) of Libya [PDF]
Egyptian Academic Journal of Biological Sciences. A, Entomology, 2013 We investigated honeybee populations of A. mellifera in Saharan and coastal locations in Libya to fill the North Africa gap of biogeography and distribution of honeybees, morphologically and using mtDNA analysis. It was found that Libyan honeybees are different, morphologically and genetically, from adjacent subspecies; and majority of Libyan bees (92%)

Forager bees (Apis mellifera) highly express immune and detoxification genes in tissues associated with nectar processing. [PDF]
, 2015 Pollinators, including honey bees, routinely encounter potentially harmful microorganisms and phytochemicals during foraging. However, the mechanisms by which honey bees manage these potential threats are poorly understood.

Enzymes in honey bee (Apis mellifera L.) hemolymph
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972 Abstract 1. 1. Esterase, malate dehydrogenase, lactate dehydrogenase and α-glycerophosphate dehydrogenase isozymes from the hemolymph of mature adult worker honey bees ( Apis mellifera L.) were electrophoretically separated on polyacrylamide gel. 2. 2.
