Compatibility between Beauveria bassiana and the predator Chrysoperla externa in laboratory

Abstract

 The objective of this work was to evaluate the effect of the fungus Beauveria bassiana on eggs and larvae of Chrysoperla externa. Eggs with 24 hours and insects on 1^st, 2^nd and 3^rd instar were immersed in fungal suspensions at 1.0x10⁴ to 1.0x10⁸ conidia mL^-1. There was no fungal effect on the eggs viability. Third instar larvae were affected by B. bassiana, and the suspensions with 1.0x10⁷ and 1.0x10⁸ conidia mL^-1 interfered in the evaluated parameters.
