| dieldrin and diazinon resistance in populations of the australian sheep blowfly, lucilia cuprina, from sheep-grazing areas and rubbish tips. | populations of l. cuprina collected from adjacent sheep-grazing areas and rubbish tips in victoria (mansfield and warrnambool) and new south wales (lismore) were tested for resistance to the insecticides diazinon and dieldrin. populations from sheep-grazing areas had a significantly higher diazinon rop-1 allele frequency than those from adjacent tips with the victorian populations being more resistant than those from lismore. victorian sheep and tip populations had similar gene frequencies at th ... | 1984 | 6536262 |
