Effects of the juvenile hormone analogue (S)-methoprene on the larval development and survival of the estuarine mud crab Rhitrhopanopeus harrisii were examined in the laboratory. Crab leave continuously exposed to 1000 microg (S)-methoprene litre(-1) did not survive beyond zoeal stage I. With continuous exposure to 100 microg (S)-methoprene litre(-1), mortality significantly increased through all larval stages except for zoeal stage II, and developmental duration significantly increased through all zoeal stages but not the premetamorphic megalopa. No supernumerary larval stages occurred with exposure (S)-methoprene. Rhithropanopeus harrisii larvae appear to be more sensitive to the single isomer formulation, (S)-methophrene, than to the double isomer formulation, (S)-methoprene, used in previously documented studies.
在实验室中研究了保幼激素类似物(S)-烯虫酯对河口泥蟹哈氏仿相手蟹幼体发育和存活的影响。持续暴露于1000微克/升(S)-烯虫酯的蟹幼体在第一期蚤状幼体阶段之后无法存活。持续暴露于100微克/升(S)-烯虫酯时,除了第二期蚤状幼体阶段外,所有幼体阶段的死亡率均显著增加,并且所有蚤状幼体阶段的发育持续时间均显著增加,但变态前的大眼幼体阶段除外。暴露于(S)-烯虫酯时未出现额外的幼体阶段。哈氏仿相手蟹幼体似乎对单一异构体制剂(S)-烯虫酯比先前文献研究中使用的双异构体制剂(S)-烯虫酯更敏感。
