Suppression of pecan weevil (Coleoptera: Curculionidae) populations with entomopathogenic fungi
Environmental Entomology 12 (2), 471-474
Abstract: Field and greenhouse trials using entomogenous fungi to control pecan weevil populations demonstrated 72 and 49.8% mortality of adults after exposure to Beauveria bassiana and Metarhizium anisopliae inoculum, respectively. In addition 44.4 and 27.8%, respectively, of untreated adult weevils developed the disease when caged with a single adult contaminated with either pathogen. Larval mortality of 29.6% for B. bassiana and 6.0% for M. anisopliae was achieved with soil-applied inoculum.
