Abstract

The species diversity and seasonal abundance of biting midges of the genus Culicoides (Diptera: Ceratopogonidae) were studied in northwestern Argentina during the period 2003-2005. A total of 5437 Culicoides specimens were collected using CDC light traps in three areas of the mountainous rainforest area. The most common species were Culicoides paraensis (Goeldi) and C. insignis Lutz, Culicoides lahillei (Iches), C. venezuelensis Ortiz & Mirsa, C. debilipalpis Lutz and C. crescentis Wirth & Blanton were also collected. Culicoides paraensis was abundant during the summer, and C. insignis and C. lahillei during late summer and early fall. Accumulated rainfall was the climatic variable most related to fluctuation in abundance of C. paraensis.

摘要

2003年至2005年期间，在阿根廷西北部对蠛蠓属（双翅目：蠓科）蠓的物种多样性和季节丰度进行了研究。在山区雨林地区的三个区域使用疾控中心诱虫灯共采集到5437只蠛蠓标本。最常见的物种是巴拉那蠛蠓（戈尔迪）和伊氏蠛蠓、拉氏蠛蠓（伊切斯）、委内瑞拉蠛蠓（奥尔蒂斯和米尔萨）、弱须蠛蠓（卢茨），还采集到新月蠛蠓（沃思和布兰顿）。巴拉那蠛蠓在夏季数量众多，伊氏蠛蠓和拉氏蠛蠓在夏末和初秋数量较多。累积降雨量是与巴拉那蠛蠓数量波动最相关的气候变量。
