Efficiency of different strains of Metarhizium anisopliae for the control of Deois flavopicta

Abstract

This study was conducted through two field experiments using Brachiaria decumbens as the forage crop to evaluate the efficiency of eight strains of the fungus Metarhizium anisopliae (Metsch.) Sorokin, 1883, on the nymphs of Deois flavopicta (Stal., 1854) (Homoptera-Cercopidae), an insect pest of forage crops in Goiás state. The results obtained with both experiments show that strains of M. anisopliae were not efficient for the control of D. flavopicta at the nymph stage, inducing infection of levels below 5%.
