摘　　要：载有反口橡皮塞诱芯的三角式诱捕器是我国目前进行苹果蠹蛾Cydia pomonella(L.)监测的主要工具。在室内理论条件下悬挂自制的橡皮塞信息素诱芯,苹果蠹蛾性信息素释放持续时间为20周,最后1周的信息素剩余含量仍在500μg左右。在室外自然条件下,2个处理能够检测到信息素剩余含量的最后时间分别为第9周和第5周,剩余含量分别为33.3μg和37.7μg;装有该信息素诱芯的诱捕器能够诱集到苹果蠹蛾成虫的时间可达15周。综合室内和室外结果,得到该自制苹果蠹蛾诱芯的最长有效时间为15周,高效时间为4周。Delta traps equipped with rubber septa loaded with sex pheromone are currently major tools for codling moth monitoring Cydia pomonella （L.）. Under theoretical indoor conditions, the effective duration of sex pheromone in Delta traps was 20 weeks, with approximately 500 μg of pheromone remaining after that time. In outdoor natural conditions, two experiments indicated that the effective duration of sex pheromone in traps was 9 and 5 weeks, with 33.3 μg and 37.7 μg of pheromone remaining after these periods respectively. The effective trapping time of these traps was 15 weeks. Comparing the indoor and outdoor results, the longest duration of pheromone on rubber septa was 15 weeks, and the most effective trapping time was 4 weeks.
