| الوصف: | The resistance ratio ofHelicoverpa armigera to Cry1 Ac insecticidal protein fromBacillus thuringiensis (Bt) is 13.1- and 3.02-fold after 18 generations of selection by transgenic tobacco expressing Bt or two (Bt and CpTI) insecticidal protein genes, in which the average corrected mortality for each selection treatments is about 60%. The mortality of selected population by transgenic Bt gene tobacco is significantly lower than the control strain when fed on transgenic tobacco plants. The mortaltty of the selected population by transgenic two genes tobacco was not significantly different from the control strain. This is the first experiment under laboratory condition which has proved that transgenic two genes tobacco could significantly delay resistance development ofH. armigera compared with one gene. |
