摘要: Geographic variation in the sensitivity of cotton bollworm to U. thuringiensis insecticide protein CryIA(c) was studied to establish a geographic baseline for comparing the future population responses to the increased use of B. thuringiensis products in agriculture in China. The bollworm populations were collected from 5 ecological cotton areas of China, and the dose responses to CryIA(c) protein of mortality and growth inhibition were evaluated. The ranges of LC(50)s (50% lethal concentration) resulting in larval mortality and IC(50)s (50% inhibition concentration) of larvae grown into 3rd instars among different populations were 0.09-9.073 mu g/ml and 0.011-0.057 mu g/ml, respectively.
