项目摘要

To investigate the predation avoidance behavior of chironomid larvae to the smell of exotic fish and to make sure the larval behavior whether taken over to the next generation、 some experiments were conducted in laboratory. As a result、 In case of Chironomus kiiensis larvae grew up in an environment that was exposed to the exotic fish smell water only、 the larvae showed no predation avoidance response to the fish smell water. On the other hand、 in case of C. kiiensis larvae were fed with blood water of same species larvae and the fish smell water、 when the larvae were expused to the fish smell water、 the larvae showed a predator avoidance behavior clearly which the search feeding time was shortened. However、 it was unknown that the reaction is either carried over to the next generations.

为了研究摇蚊幼虫对外来鱼类气味的捕食回避行为，并确定幼虫行为是否能遗传给下一代，在实验室进行了一些实验。结果，如果摇蚊幼虫在仅暴露于外来鱼腥味水的环境中生长，幼虫对鱼腥味水没有表现出捕食回避反应。另一方面，如果用同种幼虫的血水和鱼腥味水喂养金线虫幼虫，当幼虫暴露于鱼腥味水时，幼虫明显表现出捕食回避行为，从而缩短了搜索取食时间。然而，目前尚不清楚该反应是否会遗传给下一代。
