''Trichilogaster'' is a small genus of chalcid wasps in the family Pteromalidae, subfamily Ormocerinae. With one described exception, they all are Australian species that are gall-formers on Australian species of'' Acacia''. The exception is an Arabian species. Apart from its ecological interest, the genus is of practical importance because some of its members are successful biocontrol agents in South Africa at least, where ''T. acaciaelongifoliae'' and ''T. signiventris'' have been established successfully to control invasive Australian ''Acacia'' species, notably ''Acacia longifolia'' and ''Acacia pycnantha''. ==Species== The species most recently recognised in a revision of the genus are: *''Trichilogaster acaciaelongifoliae'' (Froggatt, 1892) *''Trichilogaster arabica'' Ferrière, 1947 *''Trichilogaster channingi'' (Girault, 1913) *''Trichilogaster esculenta'' Ferrière, 1947 *''Trichilogaster flavivena'' (Girault, 1931) *''Trichilogaster maideni'' (Froggatt, 1892) *''Trichilogaster olgae'' Prinsloo & Neser, 2007 *''Trichilogaster pendulae'' Mayr, 1905 *''Trichilogaster signiventris'' (Girault, 1931) *''Trichilogaster stefani'' Prinsloo & Neser, 2007 "''Epiperilampus atra''", "''Epiperilampus atricorpus''" and "''Epiperilampus significatus''" are now regarded as synonyms of ''Trichilogaster maideni''. In the review, 13 species of documented host plants were listed, comprising one ''Paraserianthes'' and 12 ''Acacia'' species. 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「Trichilogaster」の詳細全文を読む スポンサード リンク
