Abstract

The effects of Isaria farinosa (Holm.) and Beauveria bassiana (Balsamo) on adult stages of sunn pests Eurygaster integriceps Puton and Eurygaster austriaca (Schrk.) were investigated at 27±1°C, 95% r.h. and 16L:8D in the laboratory. Two concentrations, 1×106 and 1×108 conidia ml-1, were used. Mortality of inoculated and non-inoculated adults was counted at 6, 9 and 12 days after treatment. Beauveria bassiana caused higher mortality of both species than I. farinosa. Neither caused significantly high mortality at 1×106 conidia ml-1. Both were more pathogenic at 1×108 conidia ml-1 and caused more than 85% mortality 12 days post treatment. Both were more pathogenic to E. austriaca. © 2013 Springer Science+Business Media Dordrecht.
