The major output from this trip was to disseminate my latest research results to peers by presenting a spoken paper entitled "Frequency and characteristics of alleles conferring resistance to the Bt toxin Cry2Ab

Monitoring for resistance to transgenic cotton

Downes, Sharon (CSIRO Entomology, )

In the 2004/05 season Bollgard II® replaced Ingard® as the transgenic variety of cotton available to Australian growers. It improves on Ingard® by incorporating an additional insecticide protein (Cry2Ab) to combat H.

Mortality of Helicoverpa in Bollgard II cotton fields and implications for Bt resistance management

Downes, Sharon (CSIRO Entomology, )

In the mid-1990's the Australian cotton industry adopted Ingard®, a transgenic variety that contains a Bt toxin (CrylAc) which is specific to the group of insects including the target Helicoverpa armigera, but ex
