resistance frequency

Catalogue: GRDC Final Reports
Insecticide resistance monitoring within this farming system complex was successfully completed for 2006/07 and 2007/08 and the results used to assess and formulate resistance management strategies... The finding is important, as the presence of resistance through a resistance mechanism already established in the field can result in unsatisfactory control and worsen the situation for the insecticides involved... The aim of the research is to continue to increase what is known about resistance frequencies and mechanisms to allow for accurate resistance detection and effective management strategies within the mixed grains/pulse/cotton farming system...

Insecticide resistance in Helicoverpa species poses one of the greatest limitations to successful pest control and economic crop production in Australia... The objective of the project was to continue investigations into the incidence of insecticide resistance in H. armigera and its subsequent management for mitigating future resistance risk in this species... Results demonstrated very low frequencies of resistance to endosulfan, pyrethroids and abamectin # in H. punctigera , despite use of the former two insecticides for over 30 years...
