摘　　要：本试验对茶尺蠖的生活习性作了进一步的研究。结果表明，茶尺蠖成虫羽化后，大多于次日晚20：00～凌晨01：00交尾，交尾高峰集中在22：00～23：00，翌日黄昏开始产卵，20：00～00：00产卵最多。不同叶位饲养幼虫对其生长发育影响很大。咀食嫩叶的幼虫生长最快，化蛹率较高；食成老叶的生长较快，化蛹率最高；而食芽头的生长最慢，化蛹率最低。The biological habits of tea geometrid （Ectropis obliqua Prout） were studied in this paper. The results showed that the adults mated during 20：00-01：00, and the mating peak arrived between 22：00-23：00. The time for egg-laying was20：00-00：00. The tests also indicated that the growth and development of larvae were greatly influenced by their foods, the tealeaves of different position. Their growth rate was the fastest when they fed on tender leaves, but the rate decreased to the lowest when they ate buds. At the same time, the pupation rate of larvae was the highest when they were reared on older leaves, while their rate declined to the lowest when they were supplied with buds.
