Potential of anamorphic entomopathogenic fungi and biological products on their base for the control of greenhouse whitefly Trialeurodes vaporariorum West. (Homoptera: Aleyrodidae) in Belarus


Abstract: Among the phytophages of the family Aleyrodidae greenhouse whitefly Trialeurodes vaporariorum West. is one of the most dangerous pests of greenhouse agrobiocenoses. The results of long-term laboratory, vegetative and field research of entomocidal activity of the mycopathogens against T. vaporariorum conducted on the base of the collection of anamorphic entomopathogenic fungi indicate their availability for application in biological control of Aleyrodidae family phytophages. Depending on the pest population number the biological efficiency of entomopathogenic fungi has made 22.6-100%. Using these entomopathogens at the initial stage of greenhouse whitefly population development allows a long-term limit of the population number. The application of the studied mycopathogens during the population number increase is also highly effective.On the basis of high-active and technological strains of entomopathogens the biological preparations Pecilomycin-B (based on Isaria fumosorosea Wize), Boverin-BL (based on Beauveria bassiana (Bals.) Vuill), Entolek (based on Lecanicillium lecanii (Zimm.) Zare & W. Gams) have been developed. These products have passed through the state registration procedure and have been approved for use in agriculture.
