A bioessay was carried out, under laboratory conditions, to evaluate the effect of B. bassiana alone, in mixture with insecticide fipronil and oil agrol on mortality of pepper weevil adults (A. eugenii). Regent (fipronil) alone or in combination with B. bassiana, and B. bassiana in formulation with agricultural oil Agrol, were efficient in controlling pepper weevil adults. The mean lethal time varied of 6.48 hours, for the insecticide Regent in mixed with Beauveria bassiana, to 50.64 hours, for fungus alone. The treatments with the insecticide alone produced 100 percent mortality on the same day of application.
