2011~2013年在黑龙江省牡丹江市通过建立昆虫吸虫塔对蚜虫迁飞的种群动态及其与气象因子的关系进行观察分析。结果表明:蚜虫迁飞期一般在5月中下旬至10月中下旬,迁飞历期为150~160 d,每周的迁飞量变化很大,每年约有6~7周为大量迁飞期;吸虫塔的监测结果对田间蚜虫的发生可以起到预警的作用;蚜虫的迁飞与气象因子密切相关,前期温度是影响蚜虫羽化迁飞的重要因子,而强降水的天气可以造成迁飞蚜数量的大幅度减少。
2011 to 2013 in Mudanjiang City, Heilongjiang Province, through the establishment of insect trichodal moth migration of aphids population dynamics and its relationship with the meteorological factors were observed and analyzed. The results showed that aphids migrated normally from mid-late May to mid-late October, with a migration period of 150-160 days. The weekly fleet movements varied greatly, with a large number of migrations occurring every 6-7 weeks The monitoring results of the trematode tower can play an early warning role in the occurrence of aphids in the field. The migration of aphids is closely related to the meteorological factors. The temperature in the early stage is an important factor that affects the emergence and spread of aphids, while the heavy precipitation can cause the migration Aphid significantly reduce the number.
