| 摘 要： | 为摸清北京地区甘薯麦蛾的发生情况,同时筛选出有效的防治药剂,2019年对密云地区甘薯麦蛾发生动态进行调查,并在幼虫发生期选用5%阿维菌素乳油等6种药剂开展防治效果试验。结果表明:7月中下旬、9月上中旬为甘薯麦蛾幼虫发生的高峰期,从发生数量上看高峰期明显,9月峰值更高;从龄期分析,第l代幼虫发生于7月,第2代发生在8月,第3代发生在9月,与黑光灯诱到的成虫发生趋势相符。在防治药剂方面,生物药剂5%阿维菌素乳油对甘薯麦蛾幼虫的防治效果良好,化学药剂3%高氯·甲维盐微乳剂、20%氰戊·马拉松乳油、10%氟苯虫酰胺悬浮剂的速效性和持效性良好,生产中建议优先选用生物农药,交替使用化学农药。

| Abstract: | Abstract: In order to find out the occurrence situation of Brachmia macroscopa Megrick in Beijing and screen out effective pesticides, the dynamics of Brachmia macroscopa Megrick in Miyun area was investigated in 2019, and the control effect of 6 pesticides including 5% avermectin EC was tested in the larval stage. The results showed that the larval peak period of Brachmia macroscopa Megrick in mid to late July and early to mid September, the peak in September was higher. From the instar analysis the first generation occurred in July, the second occurred in August and the third occurred in September, the trend was consistent with the occurrence of adult attracted by black light. Biological pesticides 5% avermectin EC could control Brachmia macroscopa Megrick effectively. The fast-acting property and persistence of chemical pesticides (3% alpha-cypermethrin EC, 20% fenvalerate-malathion EC, 10% chlorantraniliprole SC) were excellent. It was suggested that biological pesticides should be preferred for use and chemical pesticides should be used alternately. |
