摘要
初步鉴定衡阳地区稻田飞虱有７属１０种．３种主要飞虱中，早稻乳熟期前以白背飞虱为主，乳熟期后以褐飞虱为主；晚稻孕穗、抽穗期前以白背飞虱为主，后以褐飞虱为主；灰飞虱无论早、晚稻上均居第三位，全年飞虱混合种群量以早、晚稻穗期发生量最大．一般褐飞虱迁入较晚，只有明显的５代，白背飞虱迁入稍早，可发生６代．
genus including 10 species of rice planthopper atlacking paddy in
district ofHengyang have been recorded preliminarily. Early rice which is before milking
ripening peri-od is mainly damaged by Sogatella furcifera,whereas after its milking ripening
period,ricemainly damaged by Nilaparvata lugens.Late rice which is before heading period is
mainlyattacked by Sogatellafurcifera that,rice mainly attacked by Nilaparvata
lugens.Laodelphax striatella is third importance planthopper pests to the rice.During rice
headingperiod,the mixed population of the rice planthopper is of most adundance occurrence
througha yaer.As a rule Sogatella furcifera migrates to paddy field earlier relatively than that
ofNilaparvata lugens which the former has 6 generations a year and the later has only 5
gener-ations a year clearly.
