摘要
在苹果蚜虫的防治关键期,间作冬油菜的苹果园中,冬油菜植株上瓢虫数量常远高于苹果树冠。本文通过研究发现,使用助迁技术能有效促使瓢虫从冬油菜向苹果树转移,能大量提高树冠上的瓢虫数量,增加对苹果蚜虫的自然控制力。
During the critical period of apple aphid control,the quantities of ladybugs in rapes are usually much higher than those in the crowns of apple trees in the inter-planting apple orchards.Our results showed that using assisted migration technologies could effectively drive the ladybugs shift from the rapes to the apple trees.And then,ladybug quantities were greatly increased,and subsequently the apple aphids were effectively controlled by the immigrants.
