摘要
本研究选择湖北孝感地区为试验基地,采用人工饲养及田间调查的方法,对长绿飞虱的生物学特性进行了较系统的观察,并在防治技术上作了初步探讨。长绿飞虱是危害茭白的重要害虫,在湖北孝感地区一年发生4代,以卵在茭白叶鞘里越冬,每年7~8月间的2、3代危害最重;成、若虫栖息于茭白叶片上,用口器刺吸汁液和产卵器产卵为害,有趋嫩绿性和群集性,卵主要产在叶背中肋组织内;农业防治是减轻危害的重要措施;药剂防治以2%叶蝉散粉杀虫效果最好;天敌对其有一定的抑制作用。
The research was carried out in Xiaogan,Hubei Province.The biological characteristics of green slender planthopper S.Procenus(Matsumura)were systematicall observed and the control techniques of the pest were also investigated,with artificial raising and field examining methods.The green selender planthopper is a key pest which damages fewflower wildrice Ziaunia caduciflora.In Xiaogan,the pest has four generations annually,of which the second and third do the most harm.The insect passes winter in the form of diapaused egg on the dead leaves of the crop.Adults and nymths preched on the leaves,with the taxis of aggregating and sticking to greens.They are prercing-sucking and ovipositing by their mouth parts and ovipositor.The agricutural prevention is an important measure to lessen the harm.As regards insecticides,the Yechansan(2%)powder has been proved to be the most effective.Its natural enemies can also restrain the pest to a certain degree.
