Preliminary Observations on Pathogenicity of Commercial Formulations of Metarhizium anisopliae(1) and Beauveria bassiana(1) Entomopathogenic Fungi for Control of Frankliniella invasor(2) Under Laboratory Conditions

摘要

At Chiapas, Mexico, Frankliniella invasor Sakimura (Thysanoptera: Thripidae) causes large economic loses to growers of mango (Mangifera indica L.), in addition to enormous ecological impact by insecticides used to control the thrips. We evaluated two commercial formulations Meta-TNK (R) [a.i. Metarhizium anisopliae (Metsch.) Sorokin sensu lato (s.l.)] and BotaniGard (R), [a.i. Beauveria bassiana (Bals.) Vuill.] as potential alternatives for control of female F. invasor adults. We found 91 +/- 2.0 and 95 +/- 1.1% of individuals exposed to Meta-TNK (R) and BotaniGard (R), respectively, dead by 48 hours after exposure. Both formulations have promising features to be used to control F. invasor.
