The bioagents tested included Metarhizium anisopliae, Verticillium lecanii, Beauveria bassiana and Bacillus thuringinensis kurstaki. Three methods of testing the efficacy were tried which included strip method, spray method and feeding method. The bioagents were applied at 108 spores/colony using strip and spray method and 107 spores in the feeding method. The book will give a key for the management of ectoparasitic infesting honey bee colonies without using any harmful chemicals.
