Abstract

Two nematode species, one acanthocephalan species, and unidentified cestodes were recovered from a total of 481 northern bobwhites (Colinus virginianus) collected from January 1982 to December 1983 in southern Texas. The nematodes Aulonocephalus lindquisti and Trichostrongylus tenuis varied in prevalence with month and locality. Mediorhynchus papillosis was recovered from only two birds. Monthly and yearly rainfall patterns were not correlated with endoparasite intensity and prevalence, which indicates that fluctuations of populations of northern bobwhites in Texas may be caused by factors other than changes in prevalence and intensity of endoparasites.

摘要

1982年1月至1983年12月在得克萨斯州南部采集的481只北部 bobwhites（Colinus virginianus）中，共发现了两种线虫、一种棘头虫和一些未鉴定的绦虫。线虫Aulonocephalus lindquisti和Trichostrongylus tenuis的感染率随月份和地点而变化。仅从两只鸟体内发现了乳头中殖孔绦虫。月降雨量和年降雨量模式与体内寄生虫的感染强度和感染率无关，这表明得克萨斯州北部bobwhites种群的波动可能是由体内寄生虫感染率和感染强度变化以外的因素引起的。
