Abstract
Commercial formulations of two entomopathogenic fungi (Metarhizium anisopliae Metschnikoff and Beauveria bassiana Balsamo) and two strains of Bacillus thuringiensis (B. thuringiensis var. kurstaki and B. thuringiensis var. aizawai) were evaluated against S. frugiperda and H. zea in two fields in the Yucatan Peninsula. In both locations, M. anisopliae and B. bassiana had similar efficacy (Davis and Williams scale for final damage of 1.2–1.3 at Becal and 1.7–2.6 at Muna) to that of emamectin benzoate (damage level 1.4 in Becal and 2.0 in Muna) on suppressing leaf damage by S. frugiperda. These fungal-based insecticides also caused a decrease in the ear damage by H. zea. Grain yield of plots treated with these fungal-based insecticides (5900–7500 kg ha−1) was similar to that treated with emamectin benzoate (7400–7500 kg ha−1).
