SUMMARY Some insecticides to control and prevent screw‐worm fly strike by Chrysomya bezziana in calves and adult cattle were tested in field trials on cattle in Sabah, East Malaysia. Ivermectin injected subcutaneously in newborn calves at 200 μ/kq provided 10 days protection from screw‐worm fly strike, which allowed navels to dry. Ivermectin, 1% dichlofenthion plus gentian violet and 3% lindane plus pine oil smear were all effective in preventing re‐strike of treated wounds in adult cattle. A single subcutaneous injection of ivermectin at 200 μ/kg was effective, whereas it was necessary to re‐apply the dichlofenthion and lindane smear preparations every 48h.
