翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Entomophthora muscae ： ウィキペディア英語版 Entomophthora muscae ''Entomophthora muscae'' is a species of pathogenic fungus in the order Entomophthorales which causes a fatal disease in flies. It can cause epizootic outbreaks of disease in houseflies and has been investigated as a potential biological control agent. ==Life cycle== Soon after a fly dies from infection with this pathogenic fungus, large primary conidia are produced at the apex of a conidiophore which emerge from the intersegmental membranes. When the spores are mature they are forcibly ejected and may fall onto flies resting nearby. If no hosts are available for infection, a smaller secondary conidium may develop. The conidia germinate within a few hours and a germ tube begins to penetrate the insect's cuticle. Once this reaches the haemocoel, the protoplast flows through the tube and into the fly's haemolymph. The mycelium of the fungus may grow into an area of the brain that controls the behaviour of the fly, forcing it to land on a surface and crawl upwards. The hyphae gradually grow through the whole of the body, digesting the guts, and the fly dies in about five to seven days. When it is critically ill, it tends to crawl to a high point, straighten its hind legs and open its wings, a behaviour that ensures that the fungal spores are dispersed as widely as possible. Some three hours later, conidiophores start to develop and a new shower of conidia is initiated.〔 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「Entomophthora muscae」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.
