Aspects of phlebotomine behavior were investigated in the city of Campo Grande, Mato Grosso do Sul state. The insects were captured weekly during December 2003 to November 2005, with Centers for Disease Control light traps at seven different sites including forests and residential areas. In total, 11,024 specimens (7,805 males and 3,219 females) were collected, from which 9,963 (90.38%) were identified as Lutzomyia longipalpis, the proven vector of American visceral leishmaniasis agent. The remaining 9.62% comprised 21 species. L. longipalpis was the most frequent species in all sampled sites, and the first in the ranking of standardized species abundance index. In residential areas this species clearly predominated in the peridomicile (90.96%), in contrast to the intradomicile (9.04%); in animal shelters, it was more numerous in hen houses and prevailed at ground level, inside, and at forest edge around the residences; this aspect is worrying because this insect may remain sheltered in forested environments during the use of insecticides in homes. In the forest environment, other probable or proven vector of cutaneous leishmaniasis agents were also captured such as Lutzomyia whitmani (=Nyssomyia whitmani, sensu Galati), Lutzomyia antunesi (=Nyssomyia antunesi, sensu Galati), and Lutzomyia flaviscutellata (=Bichromomyia flaviscutellata, sensu Galati).
在巴西马托格罗索州坎波格兰德市调查了白蛉的行为特征。2003 年 12 月至 2005 年 11 月期间,每周使用疾病控制中心的诱蚊灯在七个不同地点(包括森林和居民区)捕获白蛉。共收集到 11024 只标本(7805 只雄性和 3219 只雌性),其中 9963 只(90.38%)鉴定为美洲内脏利什曼原虫的传播媒介——长角血蜱。其余 9.62%包括 21 个种。长角血蜱在所有采样地点都是最常见的物种,也是标准化物种丰度指数排名第一的物种。在居民区,这种物种在半户区(90.96%)明显占优势,而在户内(9.04%)则较少;在动物庇护所,它在鸡舍中数量更多,并且在地面、内部和住所周围的森林边缘占优势;这一方面令人担忧,因为在家庭使用杀虫剂期间,这种昆虫可能会在森林环境中得到保护。在森林环境中,还捕获了其他可能或已证明的皮肤利什曼原虫媒介,如白蛉属(Nyssomyia whitmani,Galati 意义)、白蛉属(Lutzomyia antunesi,Galati 意义)和黄足白蛉属(Lutzomyia flaviscutellata,Galati 意义)。
