The genus ''Helopeltis'', also known as mosquito bugs, is a group of Heteropterans in the family Miridae (capsid bugs). They include important pests of various crops, including cacao, cashew, cotton and tea. Now in a different subgenus, a number of similar ''Afropeltis'' species are pests in Africa. Mosquito bugs have a characteristic spine on the scutellum, which is a diagnostic feature.〔Stonedahl GM (1991) Oriental species of Helopeltis (Heteroptera: Miridae): a review of economic literature and guide to identification. ''Bulletin of Entomological Research'' 81: 465–490〕 Classification in the field is based on morphological characteristics, with considerable variations in colouration between insects of the same species (although for example, ''H. theivora'' is characteristically green and ''H. antonii'' red-brown). ==Damage and distribution== With typical Hemipteran sucking mouthparts, they pierce plant tissues and cause damage ranging from leaf tattering and fruit blemishes, to complete death of shoots, branches or whole plants. There has been evident speciation along the islands of the Malay archipelago and there may be cryptic species in this genus. ''Helopeltis'' spp. sensu stricto are important 'new encounter' pests of SE Asian cocoa 〔Entwistle PF (1972) Pests of Cocoa, Longmans, London, 779 pp〕 including: * ''H. antonii'': India through to West Irian * ''H. bakeri'': Malay peninsula and Philippines * ''H. bradyi'': Sri Lanka, Malaysia, Indonesia * ''H. clavifer'': Sabah and Papua New Guinea * ''H. collaris'': Philippines * ''H. sulawesi'': Sulawesi * ''H. sumatranus'': Sumatra * ''(H. theivora )'' (with ''H. theobromae'' as a sub-species): India through to Java 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「Helopeltis」の詳細全文を読む スポンサード リンク
