an important insecticidal target from the cotton bollworm Haihao Ma1,Yuemin Ma1, Xuehui Liu2, David H. Dyer3, Pingyong Xu2, Kaiyu Liu1, Que Lan3, Huazhu Hong4, Jianxin Peng1 & Rong Peng1 The cotton bollworm, Helicoverpa armigera, has developed strong resistance to...
Here we used laboratory experiments to evaluate cross-resistance and antagonism between Cry1Ac and Cry2Ab in cotton bollworm, Helicoverpa armigera, a major pest of cotton and other crops in Asia, Africa and Australia8. Although Bt cotton producing Cry1Ac has remained effective against this pest in...
They identified a cytochrome P450 gene (CYP6AE14) from cotton bollworm and silencing CYP6AE14 by plant-mediated RNAi can impair larval tolerance of gossypol. It is reasonable to expect that, in the future, plant-mediated RNAi will be useful in producing transgenic cottons that are resistance ...
In cotton, resistance to American bollworm was achieved by using marker‐assisted recurrent selection; they revealed highly significant differences in individuals studied by MARS for this insect resistance [214]. Advertisement 6. Gene pyramiding for MAS Gene pyramiding has been widely used for ...

Rather than assume the risks of the entire supply chain, which might run the gamut from bollworm attacks to factory strikes to sudden demand for different styles, textile and apparel corporations have focused more narrowly on buying and selling clothes on the global market. By outsourcing clothing...
Asian cotton (Gossypium arboreum L.), as a precious germplasm resource of cotton with insect resistance and stress tolerance, possesses a broad spectrum of phenotypic variation related to pigmentation. Flower color affects insect pollination and the orna

Table 1 Responses to Cry1Ac of pink bollworm larvae from a resistant strain (JL46), a susceptible strain (APHIS-S), and their hybrid F1progeny. Full size table Little or no cross-resistance to Cry2Ab The LC50of Cry2Ab was 30% higher for JL46 than APHIS-S, but this difference between...
in, for example, India,Egypt,China, andBrazil. Controls and quarantines of affected areas have helped limit the spread of the insect, and eradication has been possible in a few relatively small areas with sufficiently strict controls. The bollworm (Heliothis zea, also known as thecorn earworm)...
