Abstract
Effect of Metarhizium anisopliae (Metsch.) Sorok. and Beauveria bassiana (Bals.) Vuill. on adults of Oomyzus sokolowskii (Kurdjumov) (Hymenoptera: Eulophidae). The selectivity of the fungi Metarhizium anisopliae (Metsch.) Sorok. and Beauveria bassiana (Bals.) Vuill. to adults of the parasitoid Oomyzus sokolowskii (Kurdjumov) was evaluated. The isolates E9 of M. anisopliae and Esalq 447 of B. bassiana were used at the concentration of 10 7 conidia mL -1 . The results showed that B. bassiana and M. anisopliae reduced significantly the mean longevity of the adults about 6.7 and 4.7 days respectively. B. bassiana induced 26% and 21% of total and confirmed mortalities, respectively, while M. anisopliae caused 15% and 9% of total and confirmed mortalities, showing that the isolate of M. anisopliae was less aggressive. Therefore, in function of the presented results the combination of M. anisopliae , B. bassiana, and O. sokolowskii in the integrated management of P. xylostella may be an excellent alternative for optimizing the cabbage growing system.
