The responses of adult Lutzomyia longipalpis Lutz and Neiva to sticky traps baited with entrained volatiles from a hamster were assessed in the laboratory. In a two-choice test, significantly more females and males were caught on odour-baited sticky traps than on control traps, and only a few adults remained alive and untrapped at the end of the experiments. In contrast, significantly fewer flies of both sexes were caught in a series of tests where both traps were unbaited. Twice as many males as females were caught in the control traps in the tests with odour, an observation in accordance with known male lekking behaviour around hosts. The results show that sandflies of both sexes are attracted to traps by host odour alone, in the absence of any other host cues or pheromones from the male flies.
在实验室中评估了成年长须罗蛉（Lutzomyia longipalpis Lutz and Neiva）对用仓鼠夹带挥发物诱饵的粘性诱捕器的反应。在双选试验中，与对照诱捕器相比，气味诱饵粘性诱捕器捕获的雌性和雄性长须罗蛉明显更多，并且在实验结束时只有少数成虫存活且未被捕获。相比之下，在一系列两个诱捕器都未设诱饵的试验中，捕获的两性长须罗蛉明显更少。在有气味的试验中，对照诱捕器捕获的雄性长须罗蛉是雌性的两倍，这一观察结果与已知的雄性在宿主周围的求偶场行为一致。结果表明，在没有任何其他宿主线索或雄性苍蝇信息素的情况下，两性沙蝇仅被宿主气味吸引到诱捕器上。
