The purpose of this research was to find indeginous insect associated fungi and their virulence against Bemisia tabaci. In present study, Trichoderma longibrachiatum was isolated from cotton mealybug and its pathogenicity test was conducted against Bemisia tabaci under controlled conditions. Entomopathogenic potential of T. longibrachiatum was accessed on nymphal and adult stages of B. tabaci. Entomopathogenic activity of T. longibrachiatum was severe on nymphal stage as compared to adult B. tabaci. Germination of conidia on outer surface of nymphal and adult stage of whitefly was also observed. The Results revealed that T. longibrachiatum is an entomopathogenic fungi against B. tabaci. Trichoderma is previously known as antagonistic organism against broad spectrum fungal as well as bacterial plant pathogens but it is not commonly found as insect pathogen.
