摘　　要：2009年9月26日—10月6日对人工养殖环境棘腹蛙(Paa boulengeri)非繁殖期摄食行为进行了观察。结果显示:非繁殖期,棘腹蛙幼蛙早于成蛙出来觅食,雄蛙早于雌蛙出来觅食;棘腹蛙摄食高峰期出现在19:00—20:00。在整个摄食过程中,棘腹蛙的行为可划分为静止、跳跃、转向、捕食、侵占、驱赶、打斗、爬行。棘腹蛙幼蛙与成蛙、雌性成蛙与雄性成蛙之间在摄食行为上存在差异,其中幼蛙与成蛙之间在跳跃、转动、捕食、侵占、驱赶、打斗行为上存在显著差异(P<0.05);成年雌蛙与雄蛙之间在侵占、驱赶、打斗行为上存在显著的差异(P<0.05)。Feeding behaviors of spiny-bellied frog（Paa boulengeri） were observed.It is found out that,during non-breeding season,froglet went out earlier than adult frog to find food;and male was earlier than female.the rush hours of feeding is between 7：00pm to 8：00pm.During the process of feeding,spiny-bellied frog′s behaviors can be classified as stillness,jumping,turning,preying,aggression,expelling,fighting and crawling.Froglet and adult frog acted differently on the behaviors such as jumping,turning,preying,aggression,expelling and fighting（P0.05）;and there were major differences between male frogs and female frogs on behaviors like aggression,expelling and fighting（P0.05）.
