翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Wheat fly ： ウィキペディア英語版 Wheat fly Wheat fly ((ドイツ語:Weizengallmücke)) the name given in Europe to the ''Contarina'' (''Contarinia''?; formerly ''Cecidomyia'') ''tritici'' (Kirby), a small dipterous insect of the family of gall gnats, from its depredations on wheat, to which it is nearly as destructive as the famous and closely allied species, the Hessian fly. ==Description== The typical insect is 1/30 of an inch long, orange red, with whitish wings hairy on the edges, and black eyes. They deposit their eggs in the centre of the corolla of the wheat flower, coming out in great numbers between 7 and 9 p.m. early in June, several laying on the same ear. The eggs are hatched in eight to ten days. The larvae, footless grubs nearly an eighth of an inch long when fully grown, feed upon the flower, rendering it abortive, and not upon the stem like the Hessian fly. They are yellowish, with sharp head and truncated tail, and have a quick wriggling motion. By the first of August they descend ahout half an inch into the earth, and remain there through the winter. The pupa is narrower, rufous, and sharp at both ends. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wheat fly」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
