The life table and intrinsic rate of increase of Acanthaspis pedestris Stal (Heteroptera: Reduviidae) a predator of lepidopteran insect pests viz., Spodoptera litura (Fabricius), Earias vittella (Fabricius) and Corcyra cephalonica (Stainton) are discussed. The intrinsic rates of increase were 0.039, 0.032 and 0.028 per female per day on S. litura, E. vittella and C. cephalonica, respectively. The population multiplied 44.44, 24.79 and 19.36 times in the cohort generation time of 115.19,121.82 and 133.19 days on S. litura, E. vittella and C. cephalonica, respectively.

Abstract


The life table and intrinsic rate of increase of Acanthaspis pedestris Stal (Heteroptera: Reduviidae) a predator of lepidopteran insect pests viz., Spodoptera litura (Fabricius), Earias vittella (Fabricius) and Corcyra cephalonica (Stainton) are discussed. The intrinsic rates of increase were 0.039, 0.032 and 0.028 per female per day on S. litura, E. vittella and C. cephalonica, respectively. The population multiplied 44.44, 24.79 and 19.36 times in the cohort generation time of 115.19,121.82 and 133.19 days on S. litura, E. vittella and C. cephalonica, respectively.
