Final Report: CSE00027 - Insecticide resistance and sustainable management of aphids

Plain text source: 
No aphids were collected with MACE resistance to carbamate insecticides, including pirimicarb # - the insecticide widely recommended for GPA control in Australia... There was also no evidence of imidacloprid # resistance in Australian GPA. Border treatments were effective in reducing aphid immigration and virus transmission into canola paddocks from nearby sources, but further study is necessary to determine the effects on aphids arriving from longer distances... The results indicate that an 18 m buffer of Gaucho-treated plants has a significant effect on the immigration of aphids and the introduction of virus into canola paddocks when the aphids are arriving from adjacent areas...
