Population and damage projection ofSpodoptera litura(F.) on peanuts (Arachis hypogaeaL.) under different conditions using the age-stage, two-sex life table

Abstract

The common cutworm, Spodoptera litura (Fabricus), is the most serious pest of peanuts in Taiwan. In order to devise an ecology-based and cost-effective control program, we collected life table data and consumption rates from larvae reared indoors at a constant temperature of 25°C, or outdoors at ambient temperatures during the spring and fall of 2010. A computer simulation was then used to project the population growth and damage potential of S. litura on peanuts
