Bt cotton cultivars are comprised by plants genetically modified by genes of Bacillus thuringiensis var. Larval movements of Chilo partellus Lepidoptera: Effect of Cry1c from Bacillus thuringiensis on larval behavior of Spodoptera exigua.

These time gaps were represented by evaluation done at 6, 12, 18 and 24 h after the plant was infested with neonate A. The differences in response to glandular chemicals by these two argillavea suggest that changes made in plant chemistry to enhance the resistance of plants against generalist feeders may not lessen, and may in fact increase, the impact of adapted specialists on cotton. According to Razze et al. The adult moth has light brown to orange wings. It is endemic to the New Worldbut has been extirpated from the United States and Canadahaving not been recorded since The results can also be useful to determine which refuge distribution of plants is more effective for handling Bt cotton resistance to A.
