Triatomine species influenced volume of feces produced; Triatoma dimidiata produced the largest volume of feces followed by Panstrongylus megistus, Rhodnius prolixus, and Triatoma infestans. Moreover, stage and sex affected fecal production; 5th-stage female nymphs excreted the largest volume of feces. The amount of blood ingested was significantly correlated with the volume of feces produced in 10 out of 11 experimental groups. Triatome size and volume of feces produced were less closely correlated. Indeed, a "threshold" minimum amount of blood must be ingested before bugs are stimulated to defecate. The defecation habits of triatomines probably influence the vectorial capacity of a triatomine species to a lesser degree than do the density of domestic infestations, host affinity, and the degree of adaptation to the domestic habitat.
锥蝽种类会影响粪便产生量；二色锥蝽产生的粪便量最大，其次是大长红猎蝽、致倦库蚊和侵扰锥猎蝽。此外，发育阶段和性别会影响粪便产生；五龄雌性若虫排出的粪便量最大。在11个实验组中的10组中，摄取的血量与产生的粪便量显著相关。锥蝽大小与产生的粪便量相关性较小。实际上，在虫子受到刺激排便之前，必须摄取“阈值”最低量的血液。锥蝽的排便习性对锥蝽种类传播能力的影响可能比家庭侵扰密度、宿主亲和力和对家庭栖息地的适应程度的影响要小。
