The response to intra- and interspecific faecal assembling signals was tested in Rhodnius prolixus. Papers impregnated with excrement of R. prolixus induced the aggregation of larvae of this species, but also of those of Triatoma infestans. However, faeces belonging to T. infestans were not able to assemble larvae of R. prolixus. On the other hand, there was no response of R. prolixus to putative chemical factors from their cuticle (footprints), in contrast to T. infestans. Results are discussed as related to the ecology of both species.
在南美锥蝽中测试了对种内和种间粪便聚集信号的反应。浸有南美锥蝽粪便的纸张不仅能诱导该物种幼虫的聚集，也能诱导骚扰锥蝽幼虫的聚集。然而，属于骚扰锥蝽的粪便无法使南美锥蝽幼虫聚集。另一方面，与骚扰锥蝽不同，南美锥蝽对来自其表皮的假定化学因子（足迹）没有反应。讨论了与这两个物种生态相关的结果。
