中文摘要：

为了解连续取食抗吡虫啉褐飞虱Nilaparvata lugens（Stl）对黑肩绿盲蝽Cyrtorhinus lividipennis（Reuter）生物学特性的影响,分别用对吡虫啉（Imidacloprid）敏感的褐飞虱种群（SN种群）和极高抗吡虫啉的褐飞虱种群（RN种群）连续饲养黑肩绿盲蝽15代,观察黑肩绿盲蝽SNCF15和RNCF15种群的生物学特性。结果表明：2种群的卵期、若虫期、成虫期以及整个世代的历期、各时段的羽化率差异均不显著,但SNCF15种群的产卵期比RNCF15种群长,产卵量比RNCF15种群大,且均差异显著;SNCF15种群的卵孵化率、若虫存活率也比RNCF15稍高,且卵历期稍短。

英文摘要：

To understand the effects of feeding on brown planthopper Nilaparvata lugens（Stl）populations resistant to Imidacloprid on biological characteristics of Cyrtorhinus lividipennis（Reuter）,was fed on N.lugens which was sensitive and highly resistant to Imidacloprid for 15 successive generations,respectively.Biological characteristics of C.lividipennis SNCF15 and RNCF15 were studied.The results showed that the percentage of emergence did not vary significantly between the two colonies during egg stage,nymphal stage and adult stage,as well as every period of the whole life.Compared with RNCF15 colony,SNCF15colony had a significantly longer egg laying phase and higher spawning rate,and a relatively higher egg hatching rate as well as the survival rate of nymphs,but a shorter egg period.
