摘要在日本，对来自鳃的异尾异刺线虫和来自日本黄尾五斑Seriola quinqueradiata皮肤的贝尼登虫的产卵模式和产卵量进行了体内研究。从性成熟的H. heterocerca和B. seriolae感染3个S.在23.8 ± 0.1 °C和35 ppt盐度条件下，连续3d单独饲养，光照与黑暗交替（LD 12：12;光照06.00，光照18.00）。H. heterocerca，而B. seriolae连续产卵。共114 000 H。在18.00 h黑暗后的前3 h内收集到45.4（42.5 - 49.9）%的卵。共计662 857 B。收集seriolae卵，这些卵分布在每3小时的时间段内，范围为每日卵产量的11.1%至14.1%。从每只H. heterocerca连接在一起形成一个“蛋串”。不同的产卵模式下，H。heterocerca和B. seriolae表明，不同种利用不同的感染策略感染相同的宿主种，S. quinqueradiata。
SUMMARY Egg-laying patterns and egg production in Heteraxine heterocerca from the gills and Benedenia seriolae from the skin of Japanese yellowtail Seriola quinqueradiata in Japan were investigated in vivo. Eggs were collected every 3 h from sexually mature H. heterocerca and B. seriolae infecting 3 S. quinqueradiata kept individually over 3 consecutive days and exposed to alternating periods of illumination and darkness (LD 12:12; light on 06.00, light off 18.00) and maintained at 23·8±0·1°C and 35 ppt salinity. A well-defined egg-laying rhythm was demonstrated for H. heterocerca while B. seriolae was shown to release eggs continuously. A total of 114 000 H. heterocerca eggs was collected and of these, 45·4 (42·5–49·9)% were collected during the first 3 h period following dark at 18.00 h. A total of 662 857 B. seriolae eggs was collected and these were distributed over each 3 h period ranging from 11·1 to 14·1% of the daily egg output. All eggs extracted from the uterus of each H. heterocerca were joined together forming an ‘egg-string’. The contrasting egg-laying patterns of H. heterocerca and B. seriolae suggest that each species makes use of a different infection strategy to infect the same host species, S. quinqueradiata.
