title: Evaluation of insecticide smears for the control of screw-worm fly, Chrysomya bezziana, in Papua New Guinea.
abstract: Three new insecticide smear preparations for the control of Chrysomya bezziana larvae infesting wounds of cattle have been tested under field and laboratory conditions and compared with an established preparation EQ 335 which is based on 3% lindane. Two preparations based on 3% coumaphos proved comparable to EQ 335 in the field trials and exhibited more prolonged residual effectiveness in laboratory tests. A smear preparation based on 2.5% methoxychlor was only effective in controlling 1 and 2 day-old larvae in wounds and was generally inferior to other smears tested in the laboratory.
