Two experiments were carried out to investigate if Lutzomyia longipalpis would be attracted and stimulated to lay eggs in crevices. In the first experiment, females were introduced into a chamber and offered the choice of oviposition in a test site consisting of artificial crevices, and an open control site. Significantly more eggs were laid in the crevices of the test site than in the control site. In the second experiment, females were individually isolated in vials containing vertically placed filter papers, either folded to provide artificial crevices or arranged to offer two flat surfaces. The females isolated with the folded papers laid significantly more eggs than those isolated with the flat papers. The post-oviposition survival rates of both groups of females were, however, similar. It is suggested that the oviposition preference of the fly for the surface crevices was due to thigmotropic behaviour.
进行了两项实验，以研究长须罗蛉是否会被吸引并被刺激在缝隙中产卵。在第一个实验中，将雌性引入一个腔室，并让其在由人工缝隙组成的测试地点和开放的对照地点中选择产卵。测试地点缝隙中的产卵量显著多于对照地点。在第二个实验中，将雌性个体隔离在装有垂直放置滤纸的小瓶中，滤纸要么折叠以提供人工缝隙，要么排列成提供两个平面。与折叠滤纸隔离的雌性产卵量显著多于与平面滤纸隔离的雌性。然而，两组雌性产卵后的存活率相似。有人认为，这种苍蝇对表面缝隙的产卵偏好是由于趋触行为。
