Bionomics Of A Subterranean Gall Midge (Diptera : Cecidomyiidae) From Artemisia Ludoviciana, Ranasinghe

Theses and Dissertations

Bionomics of a gall midge that emerged from nodulelike structures of herbaceous sage, Artemisia ludoviciana Nutt., was studied as a part of a larger investigation on possible nitrogen fixation by this plant. Infested plants collected from the field were regularly examined in the laboratory where some of them were grown in a liquid nutrient medium. In the laboratory, adult midges were reared from the pupae and induction of infestation was attempted. Apparent nodulation on these plants is caused by the subterranean bud galls of a previously unknown gall midge species, Rhopalomyia subhumilis Gagne. The life history of this midge is …
