摘要
2009至2011年,分别在新疆、甘肃和宁夏的3个实验点进行了苹果蠹蛾Cydia pomonella(L.)国产迷向剂的释放效果研究。结果发现,在进行了迷向处理之后,果园中雄虫平均净诱捕量下降28.6%至100%,平均下降程度为74.1%;迷向处理区中成虫平均诱捕量明显减少,对照区域则存在诱集高峰。蛀果率及树干结茧量的调查发现,2010年和2011年,与对照区相比较,迷向处理区域的蛀果率下降程度分别为32.7%和91.0%;2009年,迷向处理区的树干结茧(蛹)数量比对照区平均降低60.5%。本研究初步证实了国产迷向制剂对苹果蠹蛾具有防治效果。
The effectiveness of domestic sex-pheromone dispensers at disrupting the mating behavior of codling moths was assessed at different experimental sites between 2009 and 2011. The rate of decline of trapped male moths ranged from 28.6% to 100%, with an average of 74.1%. After mating disruption, the average number of males trapped was much higher than at the control sites, which had obvious trapping peaks. The proportion of fruit damaged in treatment and control areas in 2010 and 2011, was 32.7% and 91.0%, respectively. In 2009 there was, on average, 60.5% fewer cocoons and pupae in the trunks of fruit trees in treatment areas than in the control areas. These results suggest that domestic sex pheromone dispensers are effective in the control of codling moth in orchards.
