A larval ascaridoid nematode from Queensland scallops

Cannon L. R. G. 1978. A larval ascaridoid nematode from Queensland scallops. International Journal for Parasitology8: 75–80. The morphology of a fourth stage larval ascaridoid found in Amusium balloti is given with observations on the double nature of the excretory system. The infection rate was 5.6% with rarely more than one worm per scallop. No seasonal change in incidence was detected and no change in incidence with host size. The systematic position, possible life cycle and economic importance of the worm are discussed.
