Abstract
Effects of the juvenile hormone analogue (S)-methoprene on the larval development and survival of the estuarine mud crab Rhithropanopeus harrisii were examined in the laboratory. Crab larvae continuously exposed to 1,000 micrograms (S)-methoprene/liter did not survive beyond zoeal stage I. With continuous exposure to 100 micrograms (S)-methoprene/liter, mortality significantly increased through all larval stages except for zoeal stage II, and developmental duration significantly increased through all zoeal stages and not the premetamorphic megalopa. No supernumerary larval stages occurred with exposure to (S)-methoprene.(Copyright (c) 1994 Elsevier Science Limited, England.)
