模拟稻飞虱迁入和田间系统调查结果表明：褐飞虱增殖倍数与迁入基数关系不显著，而与水稻生育期有密切关系，最高虫量在孕穗至齐穗期。白背飞虱最高虫量在分蘖末期，其数量和结构变化与水稻生育期无明显关系。若虫是为害水稻的主要虫态。药剂防治试验结果表明：选用虱纹灵防治稻飞虱可兼治纹枯病，优于叶蝉散和甲胺磷。防治１次以水稻孕穗初期施药（均在低龄若虫高峰时）为好。防治２次以始穗期为适期。
The results showed that there was no significant relationship between the multiplication factor of BPH and the number of immigrant base, but closely related to the growth period of rice. The maximum amount of insect pest was in the booting stage to the heading stage. The highest amount of whitebacked planthopper in the late tillering stage, its quantity and structure changes and rice growth period no significant relationship. Nymphs are the main insect states that damage rice. Pharmacological control test results show that: the use of lizards Ling control planthoppers can control sheath blight, better than the leafhopper powder and methamidophos. Prevention and treatment of rice booting an initial application (both at the peak of young nymphs) as well. Control 2 times to start the ear period is suitable.
