摘  要：
观察了小木蠹蛾Holcocerusinsularis的性行为反应 ,并采用腺体提取、空气收集、触角电位和田间试验等方法对雌蛾产生和释放性信息素的时辰节律进行了研究。结果表明 :(1)该虫羽化2 4h后性成熟 ,婚飞和交配活动主要在 1:0 0～ 4 :0 0 ,交配历时 15～ 4 5min ;(2 )大部分雌蛾一生交配 1～ 3次 ,雄蛾多数一生只交配 1次 ,雌雄比为 1∶0 89;(3)雌蛾腺体提取物中性信息素含量同蛾龄有关 ,2日龄雌蛾腺体性信息素含量最高 ;(4)雌蛾腺体中性信息素含量在 1:0 0时最高 ,而性信息素释放高峰在 2 :30。

摘  要：
The sexual behavior and the circadian rhythms of sex pheromone production and release in Holcocerus insularias were investigated in both laboratory and the field. Extraction of the sex pheromone from its glands and its collection from air, electroantennogram of the male in response to the sex pheromone and trap of moths with it in the field were performed. The results indicated that most of the moths became sexually mature after one day of emergence. Their nuptial flight and mating took place from 1:00 to 4:00 and the longest mating lasted for 45 minutes. The ratio of the females to the males was 1∶0 89. The maximum of the sex pheromone in glands appeared about 1:00 on the second day after emergence, and the peak of its release occurred about 2:30. The female mated 1～3 times, while most of the males did only one time during their life spans.
