Mortality of and on sunn pests and

The effects of (Holm.) and (Balsamo) on adult stages of sunn pests Puton and (Schrk.) were investigated at 27±1°C, 95% r.h. and 16L:8D in the laboratory. Two concentrations, 1×10 and 1×10 conidia ml, were used. Mortality of inoculated and non-inoculated adults was counted at 6, 9 and 12 days after treatment. caused higher mortality of both species than . . Neither caused significantly high mortality at 1×10 conidia ml. Both were more pathogenic at 1×10 conidia ml and caused more than 85% mortality 12 days post treatment. Both were more pathogenic to . .
