2012~2014年利用昆虫吸虫塔及田间调查结合的方法对黑龙江省黑河地区大豆田间蚜虫种群的迁飞扩散动态和田间发生情况进行观测分析。结果表明:蚜虫迁飞期在5月下旬~10月下旬,迁飞期历时140~154 d,迁飞期集中在每年的9月。田间蚜虫始见于6月中下旬,结束于8月末~9月初,田间蚜虫高峰期出现在8月。吸虫塔的监测数据对田间蚜虫的发生具有预警作用,可以监测到蚜虫的迁入式迁飞和迁出式迁飞的两个过程。
From 2012 to 2014, the dynamics of migratory and spread of aphids in the soybean field in Heihe, Heilongjiang Province and the field occurrence were observed and analyzed by using the insect trichomonas tower and field investigation. The results showed that aphids migrated from late May to late October, migration period lasted 140-154 days, and migration period concentrated in September each year. Field aphids first seen in late June, ending in late August ~ early September, the peak of aphids in the field in August. The monitoring data of trematode tower has an early warning effect on the occurrence of aphids in the field, and can monitor the two processes of moving in and out of aphids.
