The occurrence of the tachinid parasitoid Billaea rhynchophorae (Blanchard) on larvae of the palm weevil Rhynchophorus palmarum (L.) was evaluated in plantations of piassava palm (Attalea funifera Mart.) and African oil palm (Elaeis guineensis Jacquin), in southeastern Bahia, Brazil. The monthly percentages of parasitism were evaluated during 13 months, from November 2000 to November 2001, based on the comparison between the number of parasitized and non-parasitized cocoons of R. palmarum. Mean parasitism was 40% and ranged from 50% in November 2000 to 18% in July 2001. While there is no method of mass reproduction of the parasitoid, a simple management practice is recommended, in order to preserve its beneficial effects in palm plantations.
在巴西巴伊亚州东南部的瓜拉那棕榈（Attalea funifera Mart.）和非洲油棕（Elaeis guineensis Jacquin）种植园中，对寄生蝇类寄生物Rhynchophorus palm weevil（Blanchard）在棕榈象甲（Rhynchophorus palmarum (L.)）幼虫上的寄生情况进行了评估。从2000年11月到2001年11月的13个月里，根据棕榈象甲被寄生和未被寄生茧的数量对比，对每月的寄生率进行了评估。平均寄生率为40%，范围从2000年11月的50%到2001年7月的18%。虽然目前没有该寄生生物的大规模繁殖方法，但建议采取一种简单的管理措施，以保持其在棕榈种植园中的有益作用。
