摘    要:】江淮稻区白背飞虱呈迁入代至主害代的爆发型相,发生程度为基数决定型。根据白背飞虱历年田间系统调查资料和灯下虫量的逐步回归分析,证明江淮稻区主害代(2代)发生程度与迁入峰后7月15日白背飞虱总虫量显著相关(R2=0.7107),并分别建立白背飞虱预警指标。以为害损失5%以下为标准,主害代高峰期虫量为15头/穴,比原防治指标稍宽。由此提出病虫兼治的防治对策和技术规范,比原传统方法少用药1次。

关 键 词:白背飞虱;发生规律;研究;防治-对策

Abstract:The outbreak regularity and control strategy of whitebacked planthopper (WBPH) was studied in the paper. Research showed that outbreak type of WBPH is from immigrant generation to major injurious generation. Its development is on the basis of insect amount in the field. Regression analysis based on the systematical investigation and light induced insect amount showed that significant relation between major injurous generation and WBPH amounts in the field on july 15 th was set up at the same time according to injurous loss. Control standard shall be 15 insect/per. It is larger than that in the past. Therefore, a new control strategy and technological mode was pointed out in Jiang hai Rice areas. It was expanded in 1997.
Keywords:Sogatella furciferu (Horvath)  pests occurrence rule  research  preventive treatment counter measures
