摘  要：
桃蛀螟Conogethes punctiferalis(Guenée)是我国黄淮海夏玉米区的主要玉米穗部害虫,幼虫取食玉米果穗不但直接影响玉米产量,而且严重降低玉米品质。为了更好地利用性诱剂监测玉米田桃蛀螟种群动态和有效防控桃蛀螟为害,比较了桃蛀螟性信息素成分顺-10-十六碳烯醛[(Z)-10-hexadecenal,Z-16:Ald]和反-10-十六碳烯醛[(E)-10-hexadecenal,E-16:Ald]在不同配比和不同剂量下的诱蛾效果;利用筛选出的诱集效果最佳的桃蛀螟性诱剂对黄淮海夏玉米田桃蛀螟的发生动态进行了监测。结果表明,桃蛀螟性信息素成分顺反比Z∶E为1∶9、剂量100μg的诱芯对桃蛀螟雄蛾的诱蛾效果最好,2017年和2018年的总诱蛾量分别为140头/诱芯和186.3头/诱芯。2018年和2019年在黄淮海夏玉米区不同地点的监测结果发现,黄淮海夏玉米穗期桃蛀螟在8月下旬-9月上旬出现发生高峰,但高峰出现的时间和发生量因地域不同而存在差异。该配方可在生产中用于黄淮海夏玉米田桃蛀螟种群监测,为桃蛀螟的绿色防控提供技术支撑。

摘  要：
Yellow peach moth, Conogethes punctiferalis(Guenée), is one of major insect pests infesting on corn ear in Huang-Huai-Hai summer corn region in China. Corn ear was fed by larvae which can directly affect the kernel quality as well as seriously reduce yield. In order to exploit the sex pheromone for monitoring and managing the C.punctiferalis, we compared the trapping efficiency of different formulations with various ratios and dosages of(Z)-10-hexadecenal(Z) and(E)-10-hexadecenal(E). Meanwhile, we monitored the population dynamic of C.punctiferalis in summer corn fields by using the selected best formulation of sex pheromone in Huang-Huai-Hai summer corn region. The results indicated that trapping efficiency of Z∶E=1∶9 at the dosage of 100 μg was highest with the number of 140 and 186.3 moth/trap in 2017 and 2018, respectively. The peak of C.punctiferalis adult population dynamics in Huang-Huai-Hai summer corn region was from late August to early September, but the specific frequency and amount differed depending on different locations and years. Briefly, this formulation of Z∶E=1∶9 at the dosage of 100 μg can be used to monitor and control of C.punctiferalis in Huang-Huai-Hai summer corn region by trapping the male moths.
