Abstract: The aim of this study was to evaluate the effects of commercially available bioinsecticides based on Metarhizium anisopliae (Metschnikoff) Sorokin and Beauveria bassiana (Balsamo) Vuillemin, i.e., Biometha WP Plus^® (M. anisopliae), Biovéria G^® (B bassiana), Boverril WP^® (B. bassiana), Metarril WP^® (M. anisopliae), and Metiê WP^® (M. anisopliae) on the pupae and adults of Cotesia flavipes (Cameron) (Hymenoptera: Braconidae) at concentrations of 1 × 10⁹, 5 × 10⁹, and 10 × 10⁹ conidia mL^-1. This braconid is released to control the sugarcane borer, Diatraea saccharalis. In the completely randomized first experiment with each commercial product, 10 C. flavipes female adults were held individually in disposable cups, which contained a 9-cm² sugarcane leaf that had been treated with the one of the entomopathogenic fungal products. The mortality of C. flavipes females was assessed at 24, 48, 72, 96, and 120 h after treatment. In the second experiment, the same treatments were applied to C. flavipes pupae, because the latter can be exposed when the fungal products are applied to sugarcane to control various pests. In the second experiment we assessed the emergence of adults from treated pupae, the capacity of these adults to parasitize Diatraea saccharalis caterpillars, numbers of progeny of these C. flavipes, longevity of C. flavipes males and females, total adults emerged, and the percent emergence and longevity of males and females of the F1 generation. The mortality levels of C. flavipes pupae and adults were not affected by the 2 Entomopathogenic fungi. Therefore the use of Beauveria bassiana and M. anisopliae to protect sugarcane is compatible with the use of C. flavipes to suppress D. saccharalis.
