稻绿蝽(Neara viridula Linaeus)又称打屁虫、屁巴虫等。食性广,除为害水稻外,还为害小麦、玉米、高粱、芝麻、柑桔、豆类及十字花科等多种农作物。近年来,在我地区对水稻为害较严重,已从次要害虫上升为主要害虫。特别是中稻晚熟品种受害尤为严重,损失达5～15％。为了摸清发生规律及防治方法,在1983—1984两年,分别在我所、谢桥乡及江口县和石阡县进行了室内观察和田间药剂防治试验。现将两年观察结果整理如下: 一、材料和方法 (一)室内观察:当越冬成虫出现时,从田间采集成虫配对试养。用直径30cm、高25cm的盆钵,每钵栽4～5株水稻。用尼 Neara viridula Linaeus (also known as the pest insects, fart worms and so on. Broad diet, in addition to damaging rice, but also for wheat, corn, sorghum, sesame, orange, beans and cruciferous and other crops. In recent years, rice has been harmed more seriously in our region and has risen from a major pest to a major pest. In particular, late-maturing varieties of mid-bearing damage is particularly serious, the loss of up to 5 to 15%. In order to find out the law of occurrence and prevention methods, in the two years of 1983-1984, respectively, in our institute, Xieqiao Township and Jiangkou County and Shiqian County conducted indoor observation and field chemical control experiments. The results of two years are now collated as follows: First, materials and methods (A) indoor observation: When the overwintering adult appears, collected from the field adult mating test. With a diameter of 30cm, 25cm high bowl, each pot planted 4 to 5 strains of rice. With Ni
