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 1st, 2nd and 3rd instar were immersed in fungal suspensions at 1,0×104 to 1,0×10 8 conidia mL-1. There was no fungal effect on the eggs viability. Third instar larvae were affected by B. bassiana, and the suspensions with 1,0×107 and 1,0×108 conidia mL -1 interfered in the evaluated parameters.
