title: Observations on the New World screwworm fly in Libya and the risk of its entrance into Egypt.
abstract: Data on traumatic myiasis caused by Cochliomyia hominivorax in Libya were reported from August 1988 until February 1989. A total of 468 cases of screwworm myiasis were recorded in seven species of livestock and 229 humans, mainly children, were also found to be infested. Cattle and sheep were the most common hosts in livestock. In cattle, the principal infestation site was the umbilicus of neonates; in sheep, it was mainly the fatty tail. Animal myiasis reached its peak in October and November, but disappeared abruptly in winter on the onset of cold weather. Screwworm distribution was confined to the northwest of Libya. The potential dispersion of the fly from this area and the possibility of infestation of other countries, particularly Egypt, are discussed. Food and Agriculture Organization (FAO) efforts to confront the New World screwworm problem in Africa are mentioned.
