Beauveria Hassiana (Balsamo), a potential mycopesticide for efficient control of the honey bee Ectoparasitic mite, Varroa Destructor and erson and trueman [electronic resource].

Includes references.

The ectoparasitic mite Varroa destructoris Anderson and Trueman is considered a destructive pest of honey bee Apis mellifera. Potentiality of using the entomopathogenic fungi Beauveria bassiana (Balsamo) as mycoacaricide against V destructor was evaluated. Considerable effect of B. bassiana on Varroa mite numbers was recorded in treated colonies compared to the control. There were significant differences in mean numbers of mite mortality rates between treated and untreated colonies. Results indicated that conidial concentration of 5x 106 spores/g caused higher mortality rate compared to the other tested concentrations. Results showed that B. bassiana had a good potential on V destructor when was dusted more than one time (0, 6 and 1Oday). Scanning electronic microscopy examination of infected mite showed abundant hypha! growth and sporulation on treated mite cuticle.
