天敌天敌的次生寄生蜂在日本未见报道。然而，它们可能在水稻生态系统中发挥重要作用，因为它们可以减少稻飞虱的天敌鳞甲科的数量。我们在稻田和周围环境中发现了两种线虫：Cheiloneurus exitiosus(Perkins，1906)和Helegonatopus diMorphus(Hoff.，1954)。Haplogonatopus oratorius(Westwood，1833)和Anteon sp.新被认为是他的东道主。狄莫莫斯。黄曲霉的寄生很少见，但他的寄生率很高。双形体在熊本县很常见。雌雄比例(雄比例)和窝卵大小。二异形目分别为0.19和4.95。
Encyrtid secondary parasitoids of Delphacidae have not been recorded in Japan. However, they may play an important role in the rice ecosystem because they can reduce the number of Dryinidae, the natural enemies of rice planthoppers. We found two encyrtid species, Cheiloneurus exitiosus (Perkins, 1906) and Helegonatopus dimorphus (Hoffer, 1954), from rice paddies and the surrounding environment. Haplogonatopus oratorius (Westwood, 1833) and Anteon sp. were newly recognized as hosts of He. dimorphus. Parasitism of C. exitiosus was rare, but He. dimorphus was common in Kumamoto Prefecture. The sex ratio (male proportion) and clutch size of He. dimorphus was estimated as 0.19 and 4.95, respectively.
