摘要
1987年在福建省永安市系统解剖26只麻鸭,检出寄生蠕虫17种,平均感染率为88.5％,其中以台湾次睾吸虫和卷棘口吸虫最高;平均感染强度为46.83条,该群落中的寄生蠕虫分布型均为聚集分布,优势种为台湾次睾吸虫,卷棘口吸虫,宫川棘口吸虫,似椎低颈吸虫,分歧单睾绦虫,鸭双睾绦虫,裂刺四棱线虫,优势度和感染指数亦以台湾次睾吸虫为最高,群落中,两两种对间的亲和系数和关联系数均未达显著水平,x^2检验则表明,在透明前殖吸虫和厚尾束首线虫间关联显著(p<0.05)。
Seventeen species of helminths were collected from 26 domestic ducks in Yongan County, Fujian Province,in 1987.The average infection rate was 88.5%,in which,the rates of Metorchis taiwanensis and Echinostoma revolutum were highest.The average infection intensity was 46.83.The patterns of distri- bution of helminth populations were all aggragation patterns.There were 7 dominant species in the commu- nity:M.taiwanensis,E.revolutum,E.miyagawei,Hypoderaewn conoideum,A pioparaksis furcigera,Dforchis anatina,Tetramers ftssispina.Interspecific association of species pairs were not significiant with analysis of coefficients of affinity and association.But there was significiant association between Prosthogonimus peilucidus and Streptocara crassicauda with X^2 test(P<0.05).
