The main aim of this trip was to accept the invitation of the Organiser of the Symposium on "The Realities of Insecticide Resistance Management" (Dr George Georghiou) to present a paper on "Nine Years of organised pyretbroid resistance management in Heliothis armigera in Australia: what has been learned?" at the :xr~ International Congress of Entomology in Beijing. While in China the opportunity was taken to visit the cotton growing areas of central-eastern China and to review the extent and severity of the field resistance problem in cotton insects.
