The hive of the honey bee is a suitable habitat for diverse mites (Acari), including nonparasitic, omnivorous, and pollen-feeding species, and parasites. The biology and damage of the three main pest species Acarapis woodi, Varroa jacobsoni, and Tropilaelaps clareae is reviewed, along with detection and control methods. The hypothesis that Acarapis woodi is a recently evolved species is rejecte...

  Among the viruses infecting honey bees, chronic bee paralysis virus (CBPV) is known to induce significant losses in honey bee colonies. CBPV is an unclassified polymorphic single stranded RNA virus. Using RT-PCR, the virus infections in honey bees can be detected in a rapid and accurate manner. Bee samples were collected from 23 provinces of Iran, between July-September 2011 and 2012. A tota...

A study was conducted to investigate honeybee colonies absconding from beehives and its financial implication among beekeepers in Tabora and Katavi regions, Western Tanzania. Four districts were selected on the basis of adoption of improved beehives. A total of 198 beekeepers were randomly selected for interviews. Data collected from beekeepers using a questionnaire were supplemented with data ...

Flower pollen is collected by honeybee foragers, adhered on their rear legs and transported into the hives in the form of pellets. Once in the hives, bee pollen is moisturised with nectar and bee mouth secretions and due to enzymatically modifications it becomes the so-called bee-bread, the protein reservoir of young bees. Bee pollen can be artificially removed from bee legs and collected by us...
