The insect specific fungus, Beauveria bassiana (Balsamo) Vuillemin, ATCC 74040, formulated as Naturalis–L®, was highly effective for control of cotton insects in an integrated pest management system (IPM) for cotton in the Lower Rio Grande Valley of Texas. Naturalis–L® effectively controlled  populations of the boll weevil Anthonomus grandis Boheman, cotton fleahopper Pseudatomoscelis seriatus (Reuter) and silverleaf whitefly Bemisia argentifolii. Naturalis–L® was effective as an ovicide and as a larvicide on the tobacco budworm Heliothis virescens (F.) and the bollworm Helicoverpa zea (Boddie).  Population of beneficials was significantly higher in cotton fields treated with Naturalis–L® than in fields treated with conventional insecticides.  Full season control of insects was obtained in fields treated with Naturalis–L® only and in Naturalis–L®/IPM programs. Lint yields were equal to or better than yields of cotton  fields treated with conventional insecticides.
