Abstract

The incidence and economic importance of maggot wound infestation was studied at the Pahangbif Farm Sdn. Bhd. Segarnat; for a period of· four weeks. Chrysomia bezziana was found to he the only species involved in 84.4% of 45 larval samples from myiasis cases observed in a 3200 head of·beef cattle during the study. Adults flies were trapped within little success. Observations were made on behavior of adult c. bezziana that were bred· out from third stage larvae collected from wounds and reared on papaya •. Males and -females reach sexual .maturity at 3 and 6 days· respectively; mating commenced at 6 days of age. Myiasis cases were related to season, valving period as well as treatment and control methods practiced by this farm. The most favoured site was in the perineal region among adult cattle and the navel for newborn calves. Attempts were made to quantify some of the economic tosses due to screw-worm fly on this farm.
