This study examined the effects of strain Beauveria bassiana (LPSC 1067) on nymphal development time, fecundity, and adult survival in Dichroplus maculipennis and development time, fecundity, and adult survival in Dichroplus maculipennis and development time, fecundity, and adult survival in Dichroplus maculipennis and development time, fecundity, and adult survival in Dichroplus maculipennis and development time, fecundity, and adult survival in Dichroplus maculipennis and Beauveria bassiana (LPSC 1067) on nymphal development time, fecundity, and adult survival in Dichroplus maculipennis andDichroplus maculipennis and Ronderosia bergi under laboratory conditions. It was observed that infection with 1x103under laboratory conditions. It was observed that infection with 1x103 conidia/ml altered nymphal development time, fecundity, and adult survival in both species. Mortality of D. maculipennis during third through the last instar (sixth) was significantly higher among treated nymphs (66 + 3.8 %) than in controls (15 + 1.7 %). Similarly, mortality in R. bergi during third through the last instar (fifth) was higher in treated nymphs (71 + 2.8 %) than in controls (19 + 1.5 %). Nymphal development times of both infected D. maculipennis and R. bergi were longer than controls.
