Efficacy of Beauveria bassiana strain ATCC 74040 against whiteflieson protected tomato and compatibility with Nesidiocoris tenuis and Orius laevigatus
Abstract: The efficacy of Beauveria bassiana strain ATCC 74040 (Naturalis®) against whiteflies(Trialeurodes vaporariorum and Bemisia tabaci) on tomato was tested in two greenhouse trials.Furthermore, the compatibility of the formulated product with two beneficial insects,Nesidiocoris tenuis and Orius laevigatus, commonly used in Mediterranean greenhouses, wasevaluated in semi-field trials. The microbial control agent confirmed its efficacy againstwhiteflies on greenhouse tomato, already evidenced in previous studies, and affected survival ofnone of the two species of beneficials. These studies suggest that B. bassiana strain ATCC 74040can be used for the control of whiteflies in greenhouses in combination with N. tenuis andO. laevigatus.
