Abstract

The association of natural enemies is an alternative for the management of pests. The aim of the study to evaluate the effect of entomopathogenic fungi on the females of Iphiseiodes zuluagai. For this, we used the isolates 645 of Beauveria bassiana and CG 321 Metarhizium anisopliae, in the concentration of 108 conidia/mL. The treatments consisted of leaf disks of Canavalia ensiformes immersed in their suspensions. To feed the predators were used eggs of Tetranychus urticae and pollen of castor bean. The results demonstrate the viability of the association of natural enemies, since the isolates caused mortality of less than 36% of I. zuluagai

Key words
- Entomopathogenic fungus, mite, Phytoseiidae, selectivity.
