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.1 aRózsa, Lajos  uhttp://www.phthiraptera.info/Publications/0317.pdf
