摘要：

The role of the louse Trinoton anserinum (F) as an intermediate host of Sarconema eurycerca (Wehr) was investigated in swans. 8.3% of healthy swans carried one to twelve lice per bird, dispersed contagiously. Injured and lead-poisoned swans were more heavily infected. The mouthparts appear designed to penetrate the hosts' skin; the mandibles are robust and asymmetric, and the maxillae have a serrated intercutting surface. 22% fed exclusively on blood and 33% on both blood and feather. All life-cycle stages fed upon blood and the barbs and barbules from down feathers; hooklets from contour feathers were only found in adults. 9% of lice were infected with developing nematode larvae in the head, thorax or abdomen. Lice labelled with Technetium 99 m moved towards the scapulas and the wings. Lice were found to be highly active and were mobile.
