In a study of the phlebotomine sandflies (Diptera: Psychodidae) in a forest reserve in Recife, Pernambuco state, north-eastern Brazil, the sandflies landing on human bait between 1.00 and 1.42 h after sunset were collected weekly for 2 years. Although 10,287 sandflies of 10 Lutzomyia species were collected, almost all (96.5%) of the sandflies caught were Lu. umbratilis. This species and several others caught are potential vectors of some of the Leishmania parasites that cause human disease. The recorded landing rate for Lu. umbratilis peaked, at the high level of 333.3 flies/person-hour, during the collections made in May 2003.The relative rarity in the collections of males of some of the species caught probably indicates that these species do not lek on their bloodmeal sources. It is likely that the sizes of the local populations of species that are not very anthrophilic, such as Lu. flaviscutellata, are much larger than indicated by the collections made on human bait.
在巴西东北部伯南布哥州累西腓的一个森林保护区对吸血白蛉(双翅目:毛蠓科)进行的一项研究中,日落1.00至1.42小时后落在人体诱饵上的白蛉每周采集一次,持续了2年。尽管采集到了10种罗蛉属的10287只白蛉,但几乎所有(96.5%)捕获的白蛉都是荫罗蛉。该物种以及捕获的其他几种白蛉是一些导致人类疾病的利什曼原虫寄生虫的潜在传播媒介。荫罗蛉的记录着陆率在2003年5月的采集期间达到峰值,高达333.3只/人·小时。捕获的某些物种雄性在采集样本中相对稀少,这可能表明这些物种不会在其血源处求偶炫耀。像黄盾罗蛉这样不太嗜人的物种,其当地种群规模可能比在人体诱饵上采集到的数量所显示的要大得多。
