| Outline of Final Research Achievements |
Among the cecidomyiidae species that induce galls on various plants, many species utilize specific plants as host. On the other hand, species belong to the genus Asphondylia utilize multiple plants. Therefore, we attempted to clarify the reason of its wide host range and life history. In particular, we focused on the existence of symbiotic fungi, and attempted to isolate and identify them. As a result, one of the Asphondylia undescribed species, the Japanese grape berry midge that infests fruits of cultivated grapes, was supposed to be widely distributed north of Kanto District. In addition, the symbiotic fungi obtained from the fruit galls of Aucuba fruit gall midge, Asphondylia aucubae, was isolated and identified. It was compared with Japanese congeners and considered to be a new species.

| Academic Significance and Societal Importance of the Research Achievements |
ハリオタマバエ属タマバエ類には、ブドウミタマバエのように栽培植物に寄生する害虫種も含まれる。これらの生活史を明らかにすることで、防除につながる情報を得ることができる。また、植物に虫こぶを形成するという寄主特異的な特性を持ちつつ、寄生する植物が幅広いという特性も持つことから、植食性昆虫の寄主植物の利用様式を解明するには格好の研究材料でもあり学術的にも研究する意義は大きい。
