The main aim of this trip was to report to the international scientific community on the progress of the Insecticide Resistance Management Strategy that has been implemented in Australia to contain pyrethroid and endosulfan resistance. With this aim in mind, a paper was delivered on the "Field Selection for Pyrethroid Resistance Genes in Heliothis armigera in Australia". This paper discussed the importance of the mixed function oxidase gene for field resistance to pyrethroids in Australia.
