摘  要：
本文采用单个活雌蛾腺体的性信息素气体收集技术,对不同世代及实验室人工饲养的CZ品系棉红铃虫Pectinophora gossypiella(Saunders)性信息素释放速率作定量分析。结果表明,各类虫源的性信息素释放速率具有明显差异;而棉红铃虫性信息素中两种组分顺,顺-7,11-十六碳二烯醇醋酸酯和顺,反-7,11-十六碳二烯醇醋酸酯的比例保持在54.8±1.2:45.2±1.2的范围;取食相同的同一代棉红铃虫的雌蛹重与其成虫的性信息素释放速率具有正相关性。

摘  要：
The release rate and ratio of the two isomers of sex pheromone of pink bollworm, Pectino-phora gossypiella, in different seasonal generations and fed with either host plant or artificial diet were quantitatively determined by utilizing a technique to quantifying the emission of the pheromone from the secretory glands of individual female moth. The results showed that there was significant difference in the release rates of sex pheromone in the individuals of different seasonal generations, with the highest in the overwintering generation and lowest in the first generation. The ratio of the two components, Z,Z-7, 11-16:AC and Z.E.-7, 11-16:AC, were maintained within the range of 54,8 + 1.2:45.2+1.2. The release rate of sex pheromone were highly comelated with the body weights of the female reared on she same food.
