Ascocphaera apis is a fungus which causes a disease known as chalkbrood in the honey bee (Apis mellifera) larvae. The diseases has a widespread incidence in Israel and other countries causing economic damage to the beekeeping industry, so the development of a method for treatment is a matter of highly practical importance. No efficacious chemical treatment for chalkbrood exists in beekeeping practice. Even if such methods were developed, problems with chemical residues in bee products might preclude the use of such substances in the commercial sector. Therefore we focused on developing a practical biological control preparation using Bacillus sp., such as are found naturally in beehives. The Biological treatment of chalkbrood in honey bees scientific project was carried out in Israel, Thailand and Germany. The principal objective of the research work was to attempt the biological control of chalkbrood. Additional objectives were the study of the epidemiology of bee diseases and to examine various aspects of the host-parasite interaction between A. apis and the honey bee.
