The nocturnal activity of the phlebotomine sandfly Lutzomyia pseudolongipalpis and two populations of L. longipalpis s.l. from different American visceral leishmaniasis foci in Venezuela was studied using collection bottle rotator traps. The activity of L. pseudolongipalpis from Lara State was continuous throughout the night, while that of L. longipalpis s.l. from El Layero, Guárico State and from Santa Ana del Valle, Margarita Island, was greatest before 23:00 h. The activity of sandflies of both populations and sexes steadily decreased thereafter. These different patterns seem to correlate with genetic data that indicate the presence in Venezuela of at least two sibling species in the L. longipalpis complex. The advantages of the bottle rotator trap for this type of study are discussed.
使用收集瓶旋转诱捕器，对委内瑞拉不同美洲内脏利什曼病疫源地的伪长须罗蛉（Lutzomyia pseudolongipalpis）以及长须罗蛉复合种（L. longipalpis s.l.）的两个种群的夜间活动进行了研究。来自拉腊州的伪长须罗蛉的活动在整个夜间持续进行，而来自瓜里科州的埃尔拉耶罗以及玛格丽塔岛圣安娜德尔瓦莱的长须罗蛉复合种的活动在23:00之前最为活跃。此后，两个种群和性别的白蛉活动均稳步下降。这些不同模式似乎与遗传数据相关，这些数据表明在委内瑞拉的长须罗蛉复合种中至少存在两个姊妹种。讨论了瓶旋转诱捕器用于此类研究的优点。
