Genetic diversity of the honeybee in Africa: microsatellite and mitochondrial data
The use of both nuclear and mitochondrial DNA often display discordant patterns of differentiation in the honeybee is preferable when assessing the phylogeography of Apis mellifera and to determine the taxonomic status of the subspecies. Expand
Behavioural basis for social parasitism of Cape honeybees
Cape honeybee workers show important pre-adaptations for social parasitism and can cause the dwindling colony syndrome of host colonies, which is unknown why and how the host queen is lost. Expand
Heat-balling wasps by honeybees
Both species of honeybees have a thermal safety factor in heat-killing such wasp predators, and the results show remarkable thermal fine-tuning in a co-evolving predator–prey relationship. Expand
Multivariate morphometric analysis of honeybees (Apis mellifera) in the Ethiopian region
The multivariate analysis established five statistically separable morphoclusters occupying ecologically different areas, suggesting introgression among these defined honeybee populations. Expand
Effects of propolis on blood glucose, blood lipid and free radicals in rats with diabetes mellitus.
It is suggested that propolis can control blood glucose and modulate the metabolism of glucose and blood lipid, leading to decreased outputs of lipid peroxidation and scavenge the free radicals in rats with diabetes mellitus. Expand
Honeybees of Asia
Honeybees of Asia highlights phylogeny, classification, mitochondrial and nuclear DNA, biogeography, genetics, physiology, pheromones, nesting, self-assembly processes, swarming, migration and absconding, reproduction, ecology, foraging and flight, dance languages, pollination, diseases/pests, colony defensiveness and natural enemies.

On the structure and mechanical properties of beetle shells
Rose chafer beetle shells are composites of chitin fibres and proteinaceous matrix in an orthogonal plywood-like laminate. Fibre layers are connected by unique inter and intra-ply cross-links thatExpand
Material properties of arthropod cuticles: The arthrodial membranes
Summary1.On the basis of tensile mechanical properties fibre-reinforced arthropod cuticles can be classified into two main types: one in which the stiffness is provided mainly by the matrix and theExpand
Synthesis and secretion of beeswax in honeybees
The cyclical changes of organelles and chemical composition of the wax gland complex closely coincide with measured, age-related rates of wax secretion in honeybees and with biosynthetic data from other insects. Expand
Portrait of the Cape honeybee, Apis mellifera capensis
mdash; The honeybees of southern Africa were assessed for expression of the trait, diploid eggs laid by workers, worker ovariole number, spermatheca size, worker size and allozymes of malateExpand
