Frequency of Bt resistance alleles in H. armigera during 2006-2008 in Northern China.

Environmental entomology - 1 Aug 2009

Gao Yulin, Wu Kongming, Gould Fred

Abstract excerpt

Helicoverpa armigera is an important lepidopteran pest of cotton in China. From 2002, the frequency of Bt resistance alleles and quantitative shifts in larval Cry1Ac tolerance of field H. armigera population were monitored using bioassays of F(1) and F(2) offspring of isofemale lines from Xiajin...
