胡杨是我区盐碱地造林的优良树种,原为野生种,近十几年才进行人工栽培。随着人工林不断增加,害虫亦日趋增多,大青叶蝉就是其中为害严重的害虫之一。在石河子地区为害率高达96—100%。新定植林中因虫害后管理不善,造成幼林木死亡率最高的达64%,严重地影响了胡杨的发展。为此,我们对大青叶蝉进行了调查,初步掌握了它在石河子地区的生活习性及防治方法。
Populus euphratica is a good species of afforestation in saline land in our region, originally wild species, cultivated only for more than a decade. With the continuous increase of plantation and insect pests, the leafhopper is one of the most serious insect pests. Damage rate in the Shihezi region as high as 96-100%. Poor management of newly planted forests due to pests causes the highest mortality of young trees up to 64%, seriously affecting the development of Populus euphratica. To this end, we conducted a survey of the leafhopper, initially mastered its lifestyles in the Shihezi region and prevention methods.
