Integrated pest management (IPM) strategies have been suggested for the control of various insect pests. Entomopathogenic fungi and botanical insecticides such as derris extract have considerable potential to become significant components in sustainable IPM. However, the compatibility of entomopathogenic fungi with derris extracts is still unknown. Therefore, the present study was evaluated the compatibility of Beauveria sp., Metarhizium spp., and Paecilomyces spp. with derris extracts under in vitro conditions. The derris extract was used at 1% and 0.1% incorporated to a culture medium (malt extract peptone agar) and distributed into petri dishes for their effects on vegetative growth and conidia viability. The vegetative growth of all fungi tested was inhibited by 1% and 0.1% of derris extracts, but they did not affect the viability of conidia.
