| 摘 要： | 采用二化螟Chilo suppressalis(Walker)卵田间诱集的方法获得赤眼蜂Trichogramma寄生卵,室内培养羽化后,解剖并观察其雄性外生殖器特征,同时进行rDNA-ITS2序列分析,确定其为稻螟赤眼蜂T.japonicum Ashmead.BLAST分析结果表明,当地采集的供试赤眼蜂ITS2与广东的稻螟赤眼蜂相似性高达99.3%～100%.本研究首次确证吉林省存在寄生水稻二化螟的稻螟赤眼蜂自然种群. |

| Abstract: | Trichogramma wasps were collected using sentinel eggs of Chilo suppressalis(Walker) in rice fields.Through morphological identification of male genitalia and analysis of rDNA-ITS2 sequences,a Trichogramma species collected was identified as T.japonicum Ashmead.The results of sequence alignment of ITS2 region showed that Trichogramma sp.collected in Jilin had 99.3%-100% similarity with T.japonicum originated from Guangdong.The present work demonstrated for the first time that there are natural populations of... |
