脊椎动物的寄生蠕虫通常在宿主体内选择非常特异的寄生部位,且此前往往需经过宿主多个器官的移行过程。然而,其机制至今未明。本文提出一种研究蠕虫此种行为的思路,即从寄生虫自身的角度及其对环境察识的观点出发来考虑,寄生虫的环境特征及其对环境的应答活动构成了行为的基本因素。结果提示,蠕虫对宿主体内固定环境的应答通常是以定型的方式进行,假设宿主体内生理与生化的平衡给寄生虫提供了一可预测的环境,寄生虫只需感知环境信息中的少量信息即可诱发合宜的应答。然而对寄生虫的感觉及神经系统的研究存在技术困难,因此,须考虑应用多学科方法(寄生虫学、生态学、进化生物学和神经行为学等)来研究寄生虫的行为策略,预期未来的研究方向应是寄生虫感觉生理学和行为生态学的综合。
Vertebrate parasitic worms usually select a very specific parasitic sites in the host, and often have to go through the process of host multiple organs. However, the mechanism is still unknown. This paper presents a way to study the behavior of worms, that is, from the viewpoint of parasite itself and its point of view on the environment, the environmental characteristics of parasites and their responses to the environment constitute the basic factors of behavior. The results suggest that the response of worms to the host environment is usually done in a stereotypical manner. Assuming that the balance of physiology and biochemistry in the host provides a predictable environment for parasites, parasites need only sense a small amount of information in the environment Can induce the appropriate response. However, there are technical difficulties in the study of parasite sensation and nervous system. Therefore, it is necessary to consider the behavioral strategies of studying parasites using multidisciplinary approaches (parasitology, ecology, evolutionary biology and neurobehavioral) The research direction should be the combination of parasitic sensory physiology and behavioral ecology.
