白背飞虱(Sogatella furcifera Horvath)属远距离迁飞性害虫,河南省各稻区常年普遍发生,局部严重和猖獗年暴发成灾。为了摸清其发生规律,做到适时防治,控制危害,1977—1979年对其地方规律和有关的生物学和生态学进行了研究。兹将结果概述如下。
Sogatella furcifera Horvath is a long-term migratory pest. All the rice-growing areas in Henan Province are common throughout the year. Some of them are serious and rampant annual outbreaks. In order to find out the regularity of its occurrence and achieve timely prevention and control of hazards, its local laws and related biology and ecology were studied from 1977 to 1979. The results are summarized below.
