摘要
本文描述了海南山蛭的尺蠖式及蠕虫式爬行、快缩短和慢缩短、摆动、转动、清洗吸盘和亲吻运动。记述了在自然条件下海南山蛭觅食行为的程序，在买验条件下觅食行为的调节，表明影响觅食行为的因素是饥饿或动力、生长和温度。海南山蛭对环境刺激的反应的生态学意义是与取食有关的，一般饥饿的海南山蛭是负趋触、正趋光、负趋地、趋向暖温气流。这些反应使海南山蛭呈现出的状态构成觅食行为全部技能的起步，增加接近宿主动物的可能性。
Loocomotion, including crawling (vermiform crawling and inchworm crawling),shortening (slow shortening and fast shortening), oscillating, rotating, sucker cleaning,rubbing and kissing of Haemadipsa hainana has been described. A typical foraging behavioral sequence of a hungry worm has been described under natu-ral conditions. The observation of the modulation of the foraging behavior has been made un-der laboratory conditions. A number of factors influence on this behavior, such as: 1.hunger 2. growth 3. temperature. Ecological significance of behavioral responses to stimuli has concerned with feeding. Ingeneral, hungry H. hainana are negatively thigmotactic, positively photo tactic, negativelygeotactic, attracted to warm moist air currents cuch responsibilities increase the possibilitycoming into contact with an host animal. The strategic postures assumed by H. hainana con-stitutes the initial step of the repertoire of the foraging. In general, if the H. hainana re-sponses as thigmotactic, negatively photo tactic, positively geotactic and not attracted towarm moist air current. that is the character of a recently fed individual, which tends to re-tiring and to an inactive status.
