Larval development in Camallanus lacustris (Zoega, 1776): a - first-stage larva 17 hours after infection of Cyclops, lateral; b - first-stage larva 3 days after infection of Cyclops, lateral; ? — second-stage larva soon after the first molt; d — second- stage larva 5 days after infection of Cyclops; e - second-stage larva after 6 days; f - second- stage larva after 8 days; g — second-stage larva after 11 days; h — third-stage larva; i — larva during the third molt; j — fourth-stage larva (after Moravec, 1969). Third-stage larvae taken from the pyloric caeca and from the intestine of perch 4 and 5 days after they had fed on infected Cyclops are prac- tically indistinguishable from infective larvae obtained from Cyclops. The only difference is that the buccal capsule and the body are slightly wider; 13—15 days later the third larval molt begins, and the buccal capsule changes from the Paracamallanus type to the ? a m a 11 a n u s type. The fourth-stage larva is mm long and mm wide. The buccal capsule differs from that of the adult only in the smaller number of striae and in the absence of tridents; the striae become vertical and occupy the entire height of the capsule; a compact ring, like that of the adult, is present. The genital primordium, which was represented by a single cell, becomes longer, as long as the intestine. Buccal capsule mm. Length of anterior part of esophagus mm, of posterior part mm. Nerve ring situated mm from cephalic end. Length of tail mm. 36.
