Resseliella
Resseliella is a genus of gall midges in the family Cecidomyiidae containing at least 50 described species. The genus includes economically significant agricultural pests, notably R. maxima (soybean gall midge) which threatens soybean production in the north-central United States, as well as R. citrifrugis, a major citrus pest in China, and R. theobaldi (raspberry cane midge), an important pest of cultivated red raspberry in Europe. Some species exhibit mutualistic relationships with plants, such as R. kadsurae which pollinates Kadsura longipedunculata in China.
