Considerable attention has been given to delaying the evolution of insect resistance to toxins produced by transgenic crops. The major pests of cotton in Australia are the Lepidoptera Helicoverpa armigera (Hubner, 1805) and Helicoverpa punctigera (Wa

Prior to the widespread adoption of two-gene Bt cotton (Bollgard II®) in Australia, the frequency of resistance alleles to one of the deployed proteins (Cry2Ab) was at least 0.001 in the pests targeted namely, Helicoverpa armigera and Helicoverpa pu

In 1996, the Australian cotton industry adopted Ingard that expresses the Bacillus thuringiensis (Bt) toxin gene cry1Ac and was planted at a cap of 30%. In 2004-2005, Bollgard II, which expresses cry1Ac and cry2Ab, replaced Ingard in Australia, and s

Population cage experiments were employed to detect variability in fitness among Cry2Ab resistant and Cry2Ab susceptible genotypes of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae). In two experiments, reciprocal crosses between a Cry2Ab resi

F2 and F1 tests to detect resistance to Cry2Ab in Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) were performed during the 2007–2008 summer. F2 tests indicated a resistance frequency of 0.006, which is similar to the published resistance fr

Bollgard II cotton (which expresses two Bt insecticidal genes cry1Ac/cry2Ab) and conventional cotton, grown in the laboratory or field and sampled at different stages, was exposed to Helicoverpa armigera (Hubner) larvae of three genotypes: homozygous

Alleles conferring resistance to Cry2Ab toxin occur at a frequency of 0.0033 in Australian populations of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae), and it is evident that detectable levels of resistance predated the introduction of tran

Transgenic cotton, Gossypium hirsutum L., expressing the crylAc and cry2Ab genes from Bacillus thuringiensis (Bt) Berliner variety kurstaki in a pyramid (Bollgard II) was widely planted for the first time in Australia during the 2004-2005 growing sea

The use of conventional chemical insecticides and bacterial toxins to control lepidopteran pests of global agriculture has imposed significant selection pressure leading to the rapid evolution of insecticide resistance. Transgenic crops (e.g., cotton
