The sex-ratio pattern of an exceptional population of human head lice (collected in the Colombo Prison, Ceylon, in 1934 to 1936) was found to be consistent with a current hypothesis on adaptive sex-ratio manipulation. Data suggest that the louse burdens were isolated and, therefore, small burdens were inbred. Thus, local mate competition favored females that produced offspring with a female bias. This is the first report to suggest that anopluran lice are capable of adaptive sex-ratio manipulation.
1934年至1936年在锡兰科伦坡监狱收集的一群特殊人头虱的性别比例模式，被发现与当前关于适应性性别比例操纵的假设一致。数据表明，虱子群体是孤立的，因此小群体是近亲繁殖的。因此，本地配偶竞争有利于产生偏雌性后代的雌性。这是第一份表明无尾类虱子能够进行适应性性别比例操纵的报告。
