Mortality of Isaria farinosa and Beauveria bassiana on sunn pests Eurygaster integriceps and Eurygaster austriaca

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, 1×10 6 and 1×10 8 conidia ml -1 , were used. Mo...

Description
Summary: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, 1×10 6 and 1×10 8 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 1×10 6 conidia ml -1 . Both were more pathogenic at 1×10 8 conidia ml -1 and caused more than 85% mortality 12 days post treatment. Both were more pathogenic to E . austriaca .
