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.
