日本弯翅虱Elenchus japonicus是褐飞虱Nilaparvata lugens、白背飞虱Sogatella furcifera和灰飞虱Laodelphax striatellus等稻飞虱的主要寄生蜂。Elenchus的另一种，E. yasangsui，这被认为是同义词E.在南亚也有描述。然而，有限的生物学和分子生物学数据，这一重要的寄生性稻飞虱。在本研究中，E. japonicas-stylopized稻飞虱从亚洲和日本的不同地区获得。对40份大肠杆菌的18 S核糖体RNA基因和线粒体细胞色素氧化酶I基因进行了序列分析。n：14从N. lugens，S. furcifera和20 fromL.纹状体。序列分析表明，E. - 是的三种类型的E。其中1株仅从mL中分离得到。产于日本北方的条纹虫。另外两种类型在亚洲大面积采集的三种稻飞虱中均有发现。这些结果表明，三种不同的基因型elenchus可以与特定的地理区域和/或稻飞虱物种。以前描述的两个Elenchus物种和目前的三个基因型之间的关系需要阐明。
The twisted-wing parasiteElenchus japonicusis a major parasitoid of rice planthoppers (Hemiptera: Delphacidae), including the brown planthopperNilaparvata lugens, the white-backed planthopperSogatella furcifera, and the small brown planthopperLaodelphax striatellus. AnotherElenchusspecies,E. yasumatsui, which is considered to be synonymous withE. japonicus, has also been described in southern Asia. However, limited biological and molecular data on this important parasitoid of rice planthoppers are available. In this study,E. japonicas-stylopized planthoppers were obtained from various regions in Asia and Japan. Sequences of the nuclear 18S ribosomal RNA gene and the mitochondrial cytochrome oxidase I gene of the strepsipterans were analyzed from 40 samples ofE. japonicus: 14 fromN. lugens, 6 fromS. furciferaand 20 fromL. striatellus. Sequence analysis of these samples revealed three genotypes ofE. japonicus. Of the three types ofE. japonicus, one was isolated only fromL. striatellusfrom northern Japan. The other two types were found in all three rice planthopper species collected from a wide area in Asia. These results suggest that the three different genotypes ofElenchuscan be associated with a particular geographical region and/or planthopper species. The relationship between two previously describedElenchusspecies and the present three genotypes needs to be elucidated.
