PROBLEM TO BE SOLVED: To provide a method for creating a bacterial strain having a wide host range showing its pathogenicity in a microbial pesticide containing insect-pathogenic filamentous fungi, Verticillium lecanii, as an active ingredient, and a microbial pesticide using the bacterial strain. SOLUTION: The present invention provides a method for creating a bacterial strain simultaneously having high pathogenicity against aphides, whiteflies and thrips by fusing filamentous fungi Verticillium lecanii B-2 strain (MAFF238429) (Japanese Laid-open N0. 2003-335612) having fixing ability on the surface of plants such as phylloplane with Verticillium lecanii IMI 179172 strain or Verticillium lecanii IMI 268317 strain. Therefore it is possible to provide a microbial pesticide having fixing ability to plant surface and wide insecticidal activity by using a microbial pesticide containing one useful insect-pathogenic filamentous fungi as an active ingredient for controlling the aphides, the whiteflies and the like in vegetables such as tomatoes and green peppers.
