天目山蛭PAE行为谱的初步研究

A Preliminary Investigation into the PAE Ethogram of Haemadipsa tianmushana

天目山蛭(Haemadipsa tianmushana)是中国的特有蛭种,在我国南方的一些山林中较为常见,其吸血习性对当地群众的生产与生活造成了不同程度的危害。近年,我们在湖南西北部的4个国家级自然保护区对其行为发生状态、程式和环境进行观察,共分辨和记录到7种姿势、32种动作、32种环境和27种行为,将这些行为归为休息、运动、觅食、防御、调温、生殖和排遗7类,进而构建了基于PAE编码系统的行为谱,为蛭类的行为生态学提供了新的资料,有助于蛭类行为比较及行为发育方面的深入研究,对于山蛭危害的防治也有理论意义。

Haemadipsa tianmushana is an endemic leech species in China, which is common in some mountain forests in southern China, and its blood-sucking habit has caused varying degrees of harm to the production and life of local people. In recent years, we have investigated the behavioral occurrence status, program and environment of Haemadipsa tianmushana in the four national nature reserves in northwestern Hunan province, and discriminated and recorded a total of 7 postures, 32 movements, 32 environments and 27 behaviors, and classified these behaviors into 7 categories including resting, locomotion, foraging, defense, thermoregulation, reproduction and excretion, and then constructed an ethogram of this leech species based on the PAE coding system. This paper provided some basic information on the behavioral ecology of leeches and contributed to in-depth research on behavioral comparison and development of leeches, as well as had theoretic significance for the prevention and control of land leeches.
