Both nectar and pollen are collected in portions of 20 to 30 mg. This requires four to five times more nectar foragers than pollen foragers in the hive.

New veterinary medicinal products developed as antiparasitic treatments controlling Varroa mite infestation in bees should satisfy the usual requirements for authorisation. Varroa control implies a number of integrated pest management measures,

Pollinator activity is required for the world’s quarter million angiosperm species to reproduce, and as a result for fruits and seeds to be produced. Honeybees (Apis mellifera L.) are amongst the most specialised, arguably the most dominant pollinators and are essential for certain agriculturally important crops.

There is growing recognition that the gut microbial community regulates a wide variety of important functions in its animal hosts, including host health. However, the complex interactions between gut microbes and environment are still unclear.

The association between the deformed wing virus and the parasitic mite Varroa destructor has been identified as a major cause of worldwide honeybee colony losses.

Next we tested the temperature range that causes damage to the mites. The mites did not survive 10°C over the normal brood nest temperature. Similar experiments with bee pupae confirmed their significantly lower heat sensitivity.

This booklet provides the beekeeper fundamental and important information about the management of small hive beetles. Topics covered include small hive beetle biology, economic importance, control recommendations, and current tools that are available for beetle control.

In the early 2000s, Italian beekeepers began to report bee mortality events linked to maize sowing. Evidence pointed to three neonicotinoids (imidacloprid, clothianidin, thiamethoxam) and a phenylpyrazole (fipronil) used for seed dressing that were dispersed in the environment during sowing.

Heritabilities and genetic correlations were estimated for honey yield and behavioural traits in Austrian honey bees using data on nearly 15,000 colonies of the bee breeders association Biene Österreich collected between 1995 and 2014.
