摘要
楚雄腮扁叶蜂Cephalica chuxiongnica是云南省危害松树较严重的食叶害虫之一。为探明该虫羽化及生殖行为的发生规律,进行室内饲养观察和野外调查。结果表明：楚雄腮扁叶蜂集中在化蛹后6、7 d羽化,主要发生于11：00—17：00,雄蜂羽化高峰较雌蜂早1h;当日羽化雌蜂即可求偶,主要发生于11：00—16：00,在13：00达到高峰;1、2日龄雌蜂求偶活性强,求偶率分别为56.1%和65.9%;11：00—17：00为楚雄腮扁叶蜂交配活跃期,1-4日龄雌蜂交配率分别为48.9%,55.6%,42.2%和28.9%,5日龄则很少交配;雌蜂林间产卵量41-68粒,平均（54.93±7.34）粒。
The pine sawfly,Cephalica chuxiongnica Xiao,is one of serious pine defoliators in Yunnan Province. The adult behavior of emergence,courtship,mating and oviposition were studied to find its circadian rhythms of emergence and reproduction. The results showed that the eclosion of C. chuxiongnica occurred 6 or 7 days after the pupation,adults emerged from 11： 00 to 17： 00,and male adults emerged earlier than the females. The virgin females showed courtship behavior on the same day of the eclosion. The courtship occurred from 11： 00 to 16： 00,and the peak of courtship was 56. 1% and65. 9% respectively for 1-day-old and 2-day-old females at 13： 00. M ating behavior mainly took place from 11： 00 to 17： 00,when the mating rates of 1,2,3,4 day-old females were 48. 9%,55. 6%,42. 2%and 28. 9% respectively. The oviposition quantity of female C. chuxiongnica in the field was 41-68 eggs,and mean value was 54. 93 ± 7. 34 eggs.
