本研究评估可能的寄生阉割引起的bopyrid等足类属Parabopyella，寄生的鳃室的同时雌雄同体的虾Lysmata amboinensis。寄生虾携带胚胎，产生的幼虫显著减少（平均值+/- SD：363 +/- 102; p = 0.002）比以前寄生虾（FPS）（1297 +/-143）和与其它US（1409 +/-102）、与PS（1362 +/-234）或与FPS（1384 +/-157）配对的未寄生虾（US）。饥饿试验表明，PS，FPS和US与其他US，PS和FPS配对生产的幼虫质量没有显着差异。宿主胚胎生产仅在数量上而非质量上受到影响，可能是由于寄生虫引起的营养流失和/或内分泌干扰。宿主雄性的性系统保持完全功能，不会发生“生殖死亡”。腹足类的雌性化阻止了被寄生的雄虫成功交配，但这似乎对L。有尾动物：在从雄性向同时雌雄同体阶段过渡的过程中，腹足动物总是雌性化的，成年动物能够成功地使幼仔受精。副红球藻对寄主的雌性生殖系统有显著影响，但不引起去势。寄生于腹部的寄生虫。
This study evaluates possible parasitic castration induced by a bopyrid isopod of the genus Parabopyrella, which parasitizes the branchial chamber of the simultaneously hermaphroditic shrimp Lysmata amboinensis. Parasitized shrimp (PS) carried embryos and produced significantly fewer larvae (mean +/- SD: 363 +/- 102; p = 0.002) than formerly parasitized shrimp (FPS) (1297 +/- 143) and unparasitized shrimp (US) paired with other US (1409 +/- 102), with PS (1362 +/- 234) or with FPS (1384 +/- 157). Starvation trials revealed no significant differences in the quality of larvae produced by PS, FPS and US paired with other US, PS and FPS. Host embryo production is only quantitatively, not qualitatively, affected, probably due to nutritional drain and/or endocrine disruption caused by the parasite. The host male sexual system remains fully functional and 'reproductive death' does not occur. The feminization of pleopods that prevents parasitized males of gonochoric species from successfully copulating seems to have no effect on L. seticaudata: pleopods are always feminized during their transition from male to simultaneous hermaphrodite phase, with adults being able to successfully fertilize broods. Parabopyrella sp. significantly affects the female sexual system of its host, but does not cause castration, as recorded for L. seticaudata parasitized by the bopyrid isopod Eophryxus lysmatae (an abdominal parasite).
