大青叶蝉又名大绿浮尘子、青叶跳蝉、青头虫等。该虫在我国分布很广,食性杂,为害苹果、梨、桃、杏、樱桃、枣等多种果树和林木、农作物、蔬菜。由于先期为害农作物和蔬菜,10月才迁移聚集于果树,产卵于树皮内,往往引不起果农的重视,导致枝干表面遍体鳞伤,危害十分严重。特别是幼树受害后,枝干表面的伤口经冬春低温、干旱、大风,使枝条、树干大量失水,生长衰弱,甚至枯萎,严重时可全株死亡。为此,我们进行了该虫的生活习性观察和防治试验,取得了较好的效果。 Green leafhopper, also known as the big green floating dust, green leafhoppers, blue-headed bugs and so on. The worm is widely distributed in our country, miscellaneous foods, damage apple, pear, peach, apricot, cherry, dates and other fruit trees and trees, crops, vegetables. Due to the premature damage to crops and vegetables, they moved to gather in the fruit trees in October and spawn in the bark, which often can not attract the attention of the fruit farmer. As a result, the surface of the branches and stems are covered with bruises and the harm is very serious. Especially after the saplings have been harmed, the wounds on the branches and stems have been subjected to low temperature and drought in winter and spring, strong winds, causing a large amount of water loss of branches and tree trunks, weakening of growth and even wilting. In severe cases, the whole plant can die. To this end, we carried out the observation of the pest habits and prevention and control experiments, and achieved good results.
