摘要
杜鹃冠网蝽是杜鹃花的重要害虫,影响杜鹃花的正常生产和观赏,严重的甚至造成死亡。调查表明:在上海地区,杜鹃冠网蝽可以成虫越冬,但是以卵越冬为主;越冬卵产于杜鹃花枝梢第3叶位之后的叶片组织内,平均每叶2.5粒,第7—12叶位越冬卵量最高。
Stephanitis pyrioides is an important pest of Rhododendron.Based on the investigation in Shanghai,overwintering of Stephanitis pyrioides was dominated by the stage of eggs,supplemented by adults.Overwintering eggs were laid in the leaf tissue after the third leaf position of the branch tip of Rhododendron,with an average of 2.5 eggs per leaf,and the highest number of overwintering eggs at the 7th to 12th leaf position.
