稻虱(Laodelphax striatellus, Sogatella, furcifera, Nilaparvata lugens等)和叶蝉(Cicadella, ferruginea, Deltocephalus strialus等)是水稻的主要害虫。为了解稻田天敌对他们的控制效果及其在综合防治中的利用价值,笔者自1973年开始对浙江双季稻区(1973～1976年,温岭)、海南三季稻区(1976～1978年,崖县)和安徽单、双季稻区(1979～1981年,肥东、芜湖等)的天敌进行了较系统的调查与试验研究。下面就稻田天敌对稻虱、叶蝉的控制效果与利用等有关问题报道如下。
Laodelphax striatellus (Sogatella, furcifera, Nilaparvata lugens, etc.) and leafhoppers (Cicadella, ferruginea, Deltocephalus strialus, etc.) are the major pests of rice. In order to understand the control effect of natural enemies of paddy field and their value in the integrated control, the author started the research on double-cropping rice area (1973 ~ 1976, Wenling), Hainan three-season rice growing area (1976 ~ 1978, County) and single and double cropping area of Anhui (from 1979 to 1981, Feidong, Wuhu, etc.) were systematically investigated and tested. The following on rice paddy natural enemies of rice lice, leafhopper control effects and utilization and other related issues are reported below.
