Contarinia sp. ( Diptera : Cecidomyiidae )

This gall midge causes a dead-heart symptom similar to that produced by Acrapex species. The midge was collected from the Ito campus of Kyushu University and several other locations in Fukuoka and Saga prefectures on Kyushu Island in late Jul to early Aug 2013. Dissection of plants revealed a spiralinG deformity of the central tiller 4 to 15 cm above Ground level. In several stems, a small pinkish larva was found near the deformity. No adults were reared, but larvae were identified as a Contarinia sp. Plant deformity in response to feedinG by members of the Genus Contarinia has been reported ( Bardner et al. 1971; Brewer et al. 1994), and in sunflowers is thouGht to be associated with elevated levels of auxin ( Brewer et al. 1994). As many cecidomyiid midGes have narrow host ranGes ( GaGné 1989; Yukawa 2000; GaGné 2004), the midGe found in coGonGrass may warrant further investiGa- tion as a potential bioloGical control aGent.
