摘要
通过对3种苹果蠹蛾性诱捕器诱捕效果的比较,发现板式性诱捕器的诱捕效果最好,盆式与瓶式之间无差异;对苹果蠹蛾成虫综合防治果园和未防治果园中的时序变化以及防治措施对成虫动态变化的研究发现,在综合防治果园中苹果蠹蛾成虫的数量明显降低,第1代和第2代成虫每单位诱捕器3 d内诱捕虫头数在2头以下,盛发期前后的2次化学防治为越冬代成虫防治的关健时期.
There are obvious different efficiency among three types of pheromone traps in capturing adult codling month, Laspeyresia pornoneHa. Through a field experiment, it was indicated that the Delta sticky trap had the most efficiency among the three types, however, the water basin trap had the same efficiency as the plastic bottle trap. In addition, the development dynamics of the adult codling moth in harnessed field and unharnessed field was observed and analyzed. The result shows that the number of the adult codling month had been controlled at low level in harnessed field, about 2 adults per the Delta sticky trap for three days.
