It is especially common when spider mites occur in colonies. It requires a high spider mite density and high humidities to become established. == Mode of action== Adult gall-midges search for spider mite colonies actively and deposit eggs next to the spider mites. The larvae that hatch feed on spider mite eggs and suck them empty. It takes one week for the eggs to develop to mature larvae. The pupal stage takes approximately one week. Spider mites that are killed by the gall-midge shrivel up and become brown or black. Dozens of larvae can be found per spider mite infested leaf. White cocoons can be visible along the veins of the leaf. 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「Feltiella acarisuga」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.
