Nearly 230 species of biting midges have been recorded or described from Argentina; 38 of them are known from the Buenos Aires province and only one is cited from Martín García Island. This paper presents the results raised from six collecting trips which took place on the island during spring 2005, summer 2006 and autumn 2009. Diverse sampling sites including permanent and temporary aquatic environments were chosen, most of the ten sampling sites were ponds of diverse origin, some of these environments were covered with floating vegetation as Lemna gibba, Lemna minuscule, Salvinia biloba, Salvinia minima, Azolla filiculoides, Limnobium laevigatum, Pistia stratiotes, Spirodela intermedia, Wolffiella oblonga and Wolffia columbiana. Other sites were placed in urban and suburban areas. Adults were collected with sweep nets at sunrise and sunset and with light traps at intervals of four to five hours at night, depending on electricity availability on the island. Larvae and pupae were collected with different implements depending on characteristics of each surveyed aquatic habitat. In free standing water, they were captured with small sieves or hand pipettes and micropipettes, flotation techniques were utilized for sampling vegetated areas, free and rooted floating hydrophytes were extracted for removing insects among them. Thirteen species of Ceratopogonidae were collected, three of Atrichopogon Kieffer, three of Forcipomyia Meigen, two of Dasyhelea Kieffer, four of Culicoides Latreille, and one of Bezzia Kieffer, all representing new records from the island.
阿根廷已记录或描述了近230种蠓；其中38种来自布宜诺斯艾利斯省，只有1种来自马丁加西亚岛。本文介绍了2005年春季、2006年夏季和2009年秋季在该岛进行的六次采集之旅的结果。选择了包括永久性和临时性水生环境在内的不同采样地点，十个采样地点中的大多数是不同来源的池塘，其中一些环境覆盖着漂浮植被，如细叶浮萍、微小小浮萍、双穗槐叶萍、小槐叶萍、细叶满江红、光叶水蕴草、大薸、中间品脐草、椭圆短颈藓和哥伦比亚无根萍。其他地点位于城市和郊区。成虫在日出和日落时用扫网采集，夜间每隔四到五小时用诱虫灯采集，具体取决于岛上的电力供应情况。幼虫和蛹根据每个被调查水生栖息地的特点用不同工具采集。在独立的水体中，用小筛子或手动移液管和微量移液管捕捉，采用浮选技术对植被覆盖区域进行采样，提取自由漂浮和扎根的漂浮水生植物以去除其中的昆虫。共采集到13种蠓科昆虫，其中3种属于无鬃蠓属，3种属于铗蠓属，2种属于毛蠓属，4种属于库蠓属，1种属于贝蠓属，均为该岛新记录。
