Industry relies heavily on the organophosphorus insecticide dichlorvos # to disinfest grain in unsealed silos... Candidates were evaluated in the laboratory against a range of pests... None of the newer compounds or combinations evaluated in the project was capable of broad-spectrum control at reasonable application rates...

Industry relies heavily on insecticides to protect stored grain, but this is under threat from resistance... Subsequently an experiment was undertaken to determine the long-term efficacy of spinosad and residue levels during storage of treated wheat at 30 C. Spinosad efficacy was relatively stable during nine months' storage, with initial doses of 0.5 and 1 mg/kg giving 100% control of adults and progeny in all bioassays of wheat taken at intervals during storage... The results from this project and DAQ00009 reinforce how difficult it is to find protectants or protectant combinations to control all of the target species or resistant strains...

Rusty grain beetle tests storage defences.. Overall, the picture of genetic resistance that has surfaced from the program - run through the Queensland Department of Agriculture, Fisheries and Forestry (DAFF), the New South Wales Department of Primary Industries (DPI) and the Department of Agriculture and Food, Western Australia (DAFWA) - is a sobering one... Overall, strong phosphine resistance is still relatively rare in Australia's stored grain pests...

In the current project, control protocols were developed for a Chinese rice weevil strain which is more resistant to phosphine than any Australian strains... Results from fumigation at different concentrations of phosphine confirmed the presence of a very high level of resistance in Chinese rice weevils... Results confirmed the presence of a very high level of resistance in this Chinese strain, even after five years without exposure to phosphine...

Mortality and reproduction of adult beetles and psocids exposed for two weeks to wheat treated with spinosad #or imidacloprid #... Mortality and reproduction of adult beetles exposed for two weeks to wheat treated with combinations of spinosad, s-methoprene# and chlorpyrifos-methyl#. The species tested were Sitophilus oryzae strain QSO393 (So), Tribolium castaneum strain QTC279 (Tc).. Mortality and reproduction of adult psocids exposed for two weeks to wheat treated with combinations of spinosad and chlorpyrifos-methyl...
