The inheritance of resistance to phosphine was studied in two strains of the lesser grain borer, Rhyzopertha dominica (F.), labeled 'Weak-R' and 'Strong-R'. These strains were purified versions of field-selected populations collected in Queensland, A

The genetics of phosphine resistance was studied in a resistant strain of the red flour beetle, Tribolium castaneum (Herbst), developed from field collections in Queensland, Australia. A program of inbreeding and selection was maintained for 5 genera

Duplicate field trials were carried out on bulk wheat in commercial silos in Queensland and New South Wales. Laboratory bioassays on samples of treated grain at intervals over 8 or 9 months storage using malathion-resistant strains of insects establi

Residues of deltamethrin on wheat grain of 12% moisture content, stored in the laboratory at 25°C, remained constant within experimental error over a 15-month interval. However, the biological activity of the residues against Sitophilus oryzae (L.)

The biological activity of freshly-applied fenitrothion on maize at a range of moisture contents was measured using adults of several species of Coleoptera. Activity declined by about ×15 as grain moisture increased from 10 to 24%, the greatest chan

Each of the combinations, bioresmethrin (1 mg kg−1) plus pirimiphos-methyl(6 mg kg−1) or fenitrothion (12 mg kg−1), was applied in 1976 to grain in 21 commercial storages. Grain condition and protectant residues were regularly monitored. Three

A field experiment was carried out on bulk sorghum stored for 26 weeks in concrete silos in South Queensland. No natural infestation occurred. Laboratory bioassays of treated grain, in which malathion-resistant strains of insects were added to grain

The accuracy and reproducibility of analytical methods for the assay of five organophosphorus grain protectants have been investigated by a coordinated test programme. Results were assessed using data from field applications of chlorpyrifos-methyl, f
