关于羽虱从亲鸟传给幼鸟的自然历史信息有限。因此，本文调查了4种羽虱在英国种群中从亲代黑鸟传给雏鸟的情况，并回答了从虱子的角度提出的问题。散布在巢中几只幼鸟身上的虱子大多在较大的雏鸟身上发现，这些雏鸟的存活前景更高。传播给雏鸟的虱子绝大多数是若虫，这在形态上不能进行性别鉴定，因此，关于成年虱子传播的将不成比例地由雌性传播的预测，只有最多的物种才得到支持。麦鲁氏布鲁氏菌。没有证据表明虱子在雏鸟身上的传播依赖于密度，而且当父母感染较严重时更有可能。最后，我预测虱子可能会聚集在雌性黑鸟身上，因为雌性黑鸟会进行更多的孵化，从而增加它们传播给雏鸟的机会。在1个种斑潜蝇身上，雌性黑鸟的寄生率高于雄性黑鸟，而不是虱子强度。另外两种虱子--吐尔迪扁虱和大黑胸蚁，雌雄之间没有明显差异。
There is limited information about the natural history of the transmission of feather lice (Phthiraptera) from parent birds to their young. This article therefore examines the transmission of 4 species of feather lice from parent blackbirds to their nestlings in an English population, and addresses questions formulated from the perspective of the lice. The lice that disperse onto the several young in the nest were mostly found on the larger chicks, those with higher survival prospects. The lice dispersing to chicks were overwhelmingly nymphs, which cannot be sexed morphologically, and so the prediction that the adult lice dispersing would be disproportionately female, potential founders of a new population, was only supported for the most numerous species. Brueelia merulensis. There was no evidence that louse dispersal to chicks was density dependent and more likely when the parents were more heavily infested. Finally, I predicted that lice might aggregate on female blackbirds, which undertake more brooding, to increase their chance of transmission to nestlings. For 1 louse species, B. merulensis, prevalence, but not louse intensity, was higher on female than male blackbirds. For 2 other louse species, Philopierus turdi and Menacanthus eurysternus, no differences between male and female blackbirds were detected.
