Data on the distribution and abundance of Lutzomyia spp. (Diptera: Psychodidae) in Bolivia is scarce. Sand flies from an area of Leishmania (Viannia) braziliensis endemicity in the Isiboro-Secure National Park in the Department of Cochabamba were captured and identified to species. In total, 945 sand flies (789 females and 156 males) belonging to 15 species were collected from the four collection points in two study villages in 2007. With 549 (58.1%) specimens, Lutzomyia shawi was the most abundant species, followed by Lutzomyia (Trichophoromyia) sp. (22.2%), Lutzomyia llanosmartinsi (8.3%), Lutzomyia antunesi (4.3%), and Lutzomyia olmeca (2.1%). Abundance and species composition varied between rainy and dry seasons, with 99.3% of all sand flies being collected outdoors. Because of species abundance and confirmed Leishmania infection in previous entomological collections, we believe Lu. shawi is the vector of L. (Viannia) braziliensis in Isiboro-Secure National Park.
玻利维亚有关 Lutzomyia spp.（双翅目：Psychodidae）分布和丰度的数据很少。从科恰班巴省伊西博罗-安全国家公园内存在利什曼原虫（Viannia）巴西利ensis 流行区的一个地区捕获并鉴定了沙蝇。2007 年，在两个研究村庄的四个采集点共采集到 945 只沙蝇（789 只雌性和 156 只雄性），属于 15 个种。Lutzomyia shawi 是最丰富的物种，有 549 只（58.1%）标本，其次是 Lutzomyia (Trichophoromyia) sp.（22.2%）、Lutzomyia llanosmartinsi（8.3%）、Lutzomyia antunesi（4.3%）和 Lutzomyia olmeca（2.1%）。丰度和物种组成在雨季和旱季之间有所不同，所有沙蝇中有 99.3%是在户外采集的。由于物种丰度和之前昆虫学采集证实的利什曼原虫感染，我们认为 Lu. shawi 是伊西博罗-安全国家公园内 L.（Viannia）巴西利ensis 的传播媒介。
