【摘要】 <正> 倍氏金蝇(Chrysomyia bezziana Villeneuve, 1914)隶丽蝇科(Calliphoridae),金蝇亚科(Chrysomyiinae),是危害人畜的一种重要蝇类,幼虫寄生于牲畜或人的创伤处而导致蝇蛆病。它在非洲为害的严重性仅次于采采蝇。我国的台湾在调查报告中指出,它是绵羊蝇蛆症的主要蝇种之一。据范滋德(1965)记载,在云南(西双版纳)和广西(南宁)幼虫可寄生于人的鼻腔,在广东(海南岛)幼虫可寄生于猪、牛牲畜体上。其它地区未见报道。此蝇以前在福建省多为散发性流行,没有引起卫生防疫工作者和兽医工作者的足够更多还原

【Abstract】 This paper reports the results of our studies on the myiasis on the body of cattle, pig and other ruminants by the fly Chrysomia bezziana Villeneuve. The results of our observations are summarized as follows: (1) The endemic areas occure in several districts in southeastern part of Fujian. Surveys were conducted to investigate the epidemiology of the disease area, and it was determined that the fly in question is its etiological agent. (2) The morphological characteristics of the fly were observed, described and figured. Laboratory experiments showed that the time required for the fly to complete its life cycle from egg to the adult is about 15—30 days under the room temperature of 25—30℃. (3) The ecology and habits of the adult were also studied. The flies begin to copulate 3 days after their emerging from pupae. Ovulation takes place 11 days afterward. During their lifetime they oviposite eggs three times The female fly lays about 201—398. eggs. The life span of adult is 16—51 days. Females live longer than males. There are 7—8 generations in a year. (4) The location of infection on the body of host, the pathological lesion produced by the maggot and the seasonal distribution of the parasite, together with other epidemiological factors were surveyed and analyzed.更多还原
