Refuge crops are used in the cotton industry to dampen the expression of resistance in Helicoverpa moths, and are an integral part in the use of transgenic cotton varieties; as such it is important to confirm refuge a

The purpose of my visit was to attend the conference in Auckland New Zealand.

H. armigera is one of the major pests faced by the Australian cotton industry.

The use of transgenic (Bt) cotton (Ingard® and more recently Bollgard II®) has greatly reduced the use of insecticides in Australian cotton production and the status of key lepidopteran pests such as Helicoverpa spp.

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
