Lutzomyia pessoai has been named as a probable vector of Leishmania braziliensis in southern Brazil. Males of this species have recently been shown to have pheromone-disseminating structures on their abdomen. Chemical analysis of extracts from the glands associated with these structures has revealed the presence of a possible sex pheromone. Although this compound has been partially characterized as a monocyclic diterpene with the same molecular weight as the Lu. longipalpis diterpene sex pheromone, mass spectral evidence indicates that it is different compound. This, the first evidence for a possible sex pheromone in any phlebotomine species other than Lu. longipalpis, indicates that such semiochemicals may be widely distributed in this group.
佩索伊白蛉已被认定为巴西南部巴西利什曼原虫的可能传播媒介。最近研究表明，该物种的雄性腹部具有释放信息素的结构。对与这些结构相关腺体提取物的化学分析显示，可能存在一种性信息素。尽管这种化合物已被部分鉴定为一种单环二萜，其分子量与长须白蛉的二萜性信息素相同，但质谱证据表明它是一种不同的化合物。这是在长须白蛉之外的任何白蛉物种中发现可能存在性信息素的首个证据，表明此类化学信号物质可能在该类群中广泛分布。
