One hundred and thirty-two male and female Triatoma sordida were marked with fluorescent paint and released at an experimental site on the salt flats of central Argentina, distant from any inhabited dwellings. Flight by these bugs commenced just after sunset, and the bugs were then systematically searched for using portable ultraviolet lights. There was no apparent tendency for the bugs to fly in any particular direction, but those whose flight could be observed directly all seemed to fly in approximately straight lines at a height of 0.5-1 m. Of the 86 bugs that flew from the release point, 16 made trivial flights of less than 5 m, 4 landed at distances of 60-90 m away, while the other bugs were not recovered and appear to have flown further than 100 m. As expected from similar studies with T. infestans, the proportion of bugs initiating flight declined with increasing weight-length ratio, but T. sordida showed a much higher propensity for flight under these conditions than did T. infestans.
132只雌雄混杂的污辱锥蝽用荧光漆做了标记，并被释放到阿根廷中部盐沼地的一个实验地点，该地点远离任何有人居住的住所。这些虫子在日落后不久开始飞行，然后使用便携式紫外线灯对它们进行系统搜索。这些虫子没有明显的朝任何特定方向飞行的趋势，但那些飞行能被直接观察到的虫子似乎都在大约0.5至1米的高度上近似直线飞行。从释放点起飞的86只虫子中，16只进行了不到5米的短途飞行，4只降落在60至90米远的地方，而其他虫子没有找到，似乎飞行超过了100米。正如对大劣按蚊进行的类似研究所预期的那样，开始飞行的虫子比例随着体重-体长比的增加而下降，但在这些条件下，污辱锥蝽比大劣按蚊表现出更高的飞行倾向。
