Baseline sensitivity of lepidopteran corn pests in India to Cry1Ab insecticidal, protein of Bacillus thuringiensis.

The article examines the sensitivity of lepidopteran corn pests in India to Cry1Ab insecticidal protein of Bacillus thuringiensis. The sensitivity of corn pests including Chilo partellus, Sesamia inferens, and Helicoverpa armigera is considered essential for resistance management practice. It was found that the multiple populations of these corn pests are susceptible to Cry1Ab. Dose-response concentrations for lethality and growth inhibition are also determined to mark baseline sensitivity.
