Effects of Bt Transgenic Cotton on Occurrence of Cotton Spider Mites in Relation to the Secondary Metabolites in Cotton
摘要
Abstract
We sought to determine the effects of Sf transgenic cotton on occurrence of cotton spider mites, and the relationship with the secondary metabolites in cotton plants. Using four Bt cotton varieties and a non-Bf cotton, CCRI 12, as the control, the abundance and developmental duration of cotton spider mites, and also the activity of their carboxylesterase(CarE) were determined, as well as the gossypol and tannin levels in cotton leaves, both in the field and in the greenhouse. Cotton spider mites were more abundant on four Bt cotton varieties than on the common cotton variety CCRI 12. The development period of cotton spider mites fed on four Bt cotton varieties was shorter than on CCRI 12. The gossypol and tannin levels in four Bt cotton varieties were significantly lower than in CCRI 12, although these also varied greatly among the Bt cotton varieties. The activity of CarE in mites fed on CCRI 12 was significantly lower than in those fed on the four Bt varieties. In general it appears that changes in secondary metabolite levels affect the occurrence of cotton spider mites in Bt cotton.关键词
