褐飞虱生物型研究中几个问题的商榷

目前在褐飞虱生物型监测中 ,由于鉴定品种及监测方法的不统一 ,使结果有出入 ,作者建议在对生物型 1进行监测时 ,鉴定品种应选用Mudgo[5] 。飞虱种群生物型的监测 ,宜以苗鉴定法为主 ,生存率测定法作参考。飞虱个体生物型测定以生存率法为主 ,苗鉴法为辅

Discussions on the experimental technique on biotype of the brown planthopper(Nilapavata lugens)

Bioassay method and rice strains used in the monitoring biotype of the brown planthopper ( Nilapavata lugens) were so different for different scientists that different conclusions on the biotype occurred frequently.The authors suggested that the Mudgo should be selected as a screening strains if biotype 1 was determined. The bulk test of seedlings should be the first chief in the mass|screening experiment ,the survivability test as reference ,while in the individual identification experiment, the biotype should be determined mainly on the results of survivability test.
