Productive efficiency of the apicultural industry depends upon improvements in bee breed, bee management and bee forage. The behavioural traits such as pollen carrying capacity, pollen and honey stores and colony population were compared for black and yellow strains of Indian honey bee Apis. cerana indica F. Observations of honey bees showing maximum activity support the conjecture that pollen ...

@r~ose. The compound eye of the honey-bee, Apis mellifera (L.), possesses retinular cells maximally sensitive to UV, blue and green wavelengths. Behavioumlly, the honey-bee exhibits trichromatic colour vision when searching for food sources and hive location. We therefore set out to sequence the opsins present in the compound eye of the honey-bee and to relate the amino acid sequences to the ph...

Varroa destructor infestation of Apis mellifera colonies carries and/or promotes replication of honey bee viruses like the Deformed wing virus, the Varroa destructor virus-1, the Acute bee paralysis virus, the Israeli acute bee paralysis virus and the Kashmir bee virus that have been well described and characterized; but viruses exclusively associated with Varroa were not found. To look for vir...

b a ckground: the varroa destructor mite is considered as a major pest of honey bees apis mellifera . the rapid spread of varroa mites among bee colonies may be due to several factors, including drifting of infested bees, movement of bee swarms, and robbing of weakened colonies. disease spread and predisposing the infested bees to other diseases lead to high economic losses in beekeeping indust...

Little is known of the potential coevolution of flowers and bees in changing, biodiverse environments. Female solitary bees, megachilids and Centris, and their nest pollen provisions were monitored with trap nests over a 17-year period in a tropical Mexican biosphere reserve. Invasion by feral Apis (i.e. Africanized honey bees) occurred after the study began, and major droughts and hurricanes o...

Diabetes elicits an increase in the oxidative stress-mediated endothelial dysfunction. Fifty male rats were divided into two main groups, first group served as control group was considered as normal non-diabetic (n=10). Second group (n=40): rats were subcutaneously injected with alloxan (150 mg/kg. body weight) for induction of diabetes. Then the diabetic rats were divided into four equal subgr...

Agricultural producers apply numerous technological procedures, and enlarging efforts to produce the high-quality products. This initiative is present in the beekeeping, too. The quality of the honey produced by the honey bee colonies depends of various factors, but prevailing are the ecological conditions and the floristic composition of the honeyfull plants. The aim of our research was to dis...

Modern agriculture relies on domesticated pollinators such as the honey bee (Apis mellifera L.), and to a lesser extent on native pollinators, for the production of animal-pollinated crops. There is growing concern that pollinator availability may not keep pace with increasing agricultural production. However, whether crop production is in fact pollen-limited at the field scale has rarely been ...

The European honey bee, Apis mellifera, is the most economically valuable pollinator of agricultural crops worldwide. Bees are also crucial in maintaining biodiversity by pollinating numerous plant species whose fertilisation requires an obligatory pollinator. Apis mellifera is a species that has shown great adaptive potential, as it is found almost everywhere in the world and in highly diverse...
