Abstract:
Several genes on chromosomes IV and VI have a significant influence on high-level resistance to diflubenzuron in a strain of the Australian sheep blowfly from Tara, Queensland. Low-level resistance to cyromazine in the same strain is due to genes on these chromosomes with a gene (gene complex) in the sv marker region of chromosome IV being particularly important. For both insecticides, genetic background influences resistance status. If the results of the Tara strain prove typical for those of other populations, resistance to diflubenzuron in the Australian sheep blowfly has potentially significant consequences for woolgrowers.
