Resumo
O objetivo deste trabalho foi avaliar os efeitos do fungo Beauveria bassiana sobre ovos e larvas de Chrysoperla externa. Ovos com até 24 horas de idade e insetos no 1º, 2º e 3º ínstares foram imersos em suspensões fúngicas de 1,0x10(4) a 1,0x10(8) conídios mL-1. Não houve efeito do fungo sobre a viabilidade dos ovos. Larvas de terceiro ínstar foram afetadas por B. bassiana, e as suspensões de 1,0x10(7) e 1,0x10(8) conídios mL-1 interferiram nos parâmetros avaliados.

Third instar larvae were affected by B. bassiana, and the suspensions with 1,0x10(7) and 1,0x10(8) conidia mL-1 interfered in the evaluated parameters.
