三年共标记释放粘蛾六批,回收7次。经全国粘虫科研协作会议肯定我省回收到粘蛾17头,表明粘虫具有远距离迁飞习性。其迁飞特点:蛾龄小的种群为迁出群,蛾龄大的种群为迁入群;蛾峰多,但一代不一定是主要蛾蜂,二三代不一定出现蛾峰;蛾龄变化大,且有规律;粘蛾成批迁飞,引起大范围内蛾量同期突增;蛾卵同期,有时蛾量大,卵量少。粘蛾的迁飞,对粘虫测报具有重要意义。
Three years mark a total of six groups of release moths, recycling 7 times. The national armyworm research collaboration meeting affirmed the province recovered moth moth 17, indicating that armyworms with long-distance migration habit. The characteristics of its migration: the moth age groups are out of the group, moth age groups are immigrants; moths and more, but the generation is not necessarily the main moths, two or three generations do not appear moth peak; moth age changes Large and regular; moth migrated in batches, causing a large range of moths sudden increase over the same period; moth eggs at the same period, sometimes a large amount of moths, less eggs. The migration of moth moths is of great significance to armyworms.
