摘要:为明确不同烟草品种对烟粉虱的抗性,本研究对烟粉虱在不同烟草品种上的发生数量和危害情况进行田间调查。2016年对13个烟草品种抗烟粉虱的调查结果显示,高感品种有中烟100、LY2829、Y7478、LJ0520,感品种有QY201、LY30605、CF232、Y056、CT141,中抗品种有 NC89、贵烟6号,抗性品种有NC55、Y8123。2017年对11个烟草品种抗烟粉虱的调查结果显示,高感品种有中烟100、延安1号、云烟87,感品种有LY937、CF228、Y077,中抗品種有CF234、K326、LJ982,抗性品种有NC89、NC55。综合2016、2017年的调查结果可知,NC55对烟粉虱的抗性最高,NC89次之,中烟100抗性最低。

Abstract In order to clear the resistance of different tobacco varieties against Bemisia tabaci, we investigated the occurrence number and harm status of Bemisia tabaci on tobacco varieties in the field. Thirteen tobacco varieties were surveyed in 2016.The corresponding results showed that Zhongyan 100, LY2829, Y7478 and LJ0520 were the high susceptible varieties. QY201, LY30605, CF232, Y056 and CT141 were the susceptible varieties. NC89 and Guiyan 6 were the medium resistant varieties. NC55 and Y8123 were the resistant varieties. Eleven tobacco varieties were investigated in 2017. The corresponding results showed that Zhongyan 100, Yanan 1 and Yunyan 87 were the high susceptible varieties. LY937,CF228 and Y077 were the susceptible varieties. CF234,K326 and LJ982 were the medium resistant varieties. NC89 and NC55 were the resistant varieties. By comprehensive analyses of the results in 2016 and 2017, it was indicated that NC55 had the highest resistance against Bemisia tabaci,followed by NC89,and Zhongyan 100 had the lowest resistance.

烟草属于茄科,烟属,目前已经有66个种。当前烟属主要栽培品种有普通烟草和黄花烟草。在植物分类上,烟草大多数是草本植物,少量灌木或乔木状植物[1,2]。烟粉虱(Bemisia tabaci Gennadius),属半翅目,粉虱科,小粉虱属,由Gennadius在希腊的烟草上发现,后命名为烟粉虱(tobacco whitefly),其寄主植物多达 74 科 500 多种,主要为害茄科、葫芦科、菊科、大戟科、十字花科等作物[3]。烟粉虱为害烟草除直接以刺吸式口器吸取烟草叶片的汁液影响正常生长外,还能够产生大量蜜露,诱发煤污病,直接影响烤烟质量[4,5]。此外,烟粉虱还传播病毒,引起烟草曲叶病毒病(简称TLCV)[1,6]。
烟粉虱是世界性的重大外来入侵性害虫[7],自2000年之后,烟粉虱在山东省、河南省等主要烟草种植区广泛发生、为害较为严重,对烟叶质量产生巨大影响[8,9]。根据诸城烟区烟粉虱动态调查结果,临近温室大棚栽烟区,烟粉虱发生频繁,并且和白粉虱混合发生,给防治工作造成一定难度[10]。……
