几种小动物活动规律的实验比较

Comparison Experimentlly Between Several Kinds of Small Animal With Regard to the Pattern of Activities

7—8月,对壁虎、螽斯、油葫芦、飞蝗、螳螂的运动性活动做了若干昼夜的连续记录。根据活动高潮出现的时间,分三种类型:(1)晚间活动:壁虎,天黑前开始,持续4小时左右,有明显的间歇。(2)白天活动:油葫芦、飞蝗、螳郎;后两者都从10时后开始,飞蝗活动到19时,螳螂活动到16时;油葫芦从早活动到晚。(3)早晚活动:螽斯,主要在6-10时。在实验条件下,这些动物无论是饱食还是饥饿,活动规律大致相同。

Patterns of motor activities of the lizard Gekko swinhonise , katydid Gampsocleis buergeri, field cricket Gryllus testaceus , locust Locusta migratoria manilensis and mantis Paratenodera sinensis were studied in laboratory by means of a 'seesaw chamber', which has been illustrated elsewhere, in July and August .According to the emergent durations of high tide of motor activites in day and night , the animal' s activites were divided into three categories : (1) in the eveving-lizard, (2) during the day-field cricket, locust and mantis , (3) in the morning and afternoon-katydid .Under the experemental condition, the same patterns were observed regardless the animals were either hunger or well-fed.
