Transmission studies carried out in the laboratory incriminated Phlebotomus vexator occidentis as a vector of a species of trypanosome that infects Bufo boreas halophilus. Toads free of parasites contracted the trypanosome after eating infected flies and after intraperitoneal inoculation of flagellates cultured from the hindgut of flies that had fed on infected toads. Discovery of this vectorhost-parasite system in the Americas, and the localization of promastigote flagellates (leptomonads) in the hindgut of the vector, should assist in clarifying interpretative problems associated with infection of wild-caught flies in studies on leishmaniasis in the Americas and elsewhere.
在实验室进行的传播研究表明，西方骚扰白蛉是一种锥虫的传播媒介，这种锥虫会感染加利福尼亚林蛙。未感染寄生虫的蟾蜍在食用感染的苍蝇后，以及在腹腔接种从以感染蟾蜍为食的苍蝇后肠培养的鞭毛虫后，感染了这种锥虫。在美洲发现这种媒介-宿主-寄生虫系统，以及前鞭毛体鞭毛虫（细滴虫）在媒介后肠中的定位，应有助于澄清美洲和其他地区利什曼病研究中与野生捕获苍蝇感染相关的解释性问题。
