摘要
记述了杜鹃网蝽与梨网蝽各自危害的寄主植物及形态区别特征。研究结果表明,危害杜鹃的是杜鹃网蝽,而不是梨网蝽;杜鹃网蝽在寄主叶背危害,1年发生5代,6~7月虫口数量最多,危害最重;杜鹃网蝽的天敌有盲蝽、蓟马等;选择阿维菌素、啶虫脒和氟虫腈进行室内药效试验,效果显著。
This paper describes the different host plants damaged by Stephanitis pyriodes and Stephanitis nashi and their shape characteristics respectly.The result showed what harmed to Rhododendron simsii is Stephanitis pyriodes,not Stephanitis nashi.Stephanitis pyriodes does harm at the back of leaf blade and it produces 5 gengerations per year.Its most population quantity appears on June to Sptember and in this period the demolishment is most serious.Stephanitis pyriodes s natural enemies contain Miridae,thrips et...
