【 摘 要 】

Colombian farmers use pesticides with toxicological category I, II and III to control the whitefly Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) in cotton and eggplant crops;although, its indiscriminate use offers a risk for the environment and the people. The use of biological control with entomopathogenic fungi can be an alternative to replace this is the use of biological control as the entomopathogenic fungi. However, the successful use of a biopesticide in an integrated pest management (IPM) would depend largely on the effect of pesticides on the entomopathogenic microorganism. The aim of this study was to determine the in vitro compatibility of a biopesticide based on the fungi Isaria fumosorosea formulated as a wettable powder (WP) to control the whitefly Bemisia tabaci with four fungicides and five insecticides currently used in cotton and eggplant crops. For this, the effect of the pesticides was evaluated at three concentrations (FR = Field recommendation; 0.5 x FR and 0.25 x FR). Effects of these products on conidia germination and the number of colony forming units (UFC)/g were compared. The four fungicides (Benlate, Carboxin Captan, Metalaxyl Mancozeb and Mancozeb) at the three doses evaluated were incompatible with the biopesticide, while one insecticide (Thiamethoxam) was compatible with the biopesticide when 0.25 x FR of its dose was tested.
