Effects of a Juvenile Hormone Mimic on Male and Female Gametogenesis of the Mud Crab, 'Rhithropanopeus harrisii' (Gould) (Brachyura: Xanthidae).

摘要

Juvenile hormone (JH) analogs are substances of natural and synthetic origin which act in the same way as endogenous JH, the endocrine secretion of the insect corpora allata. The wide range of their biological effects is now well established and has led to their study as a possible means of pest control. In consequence, nontarget organisms may also be contaminated through the food-chain or by residues of the exogenous hormone degradation; likewise, JH analogs may enter the aquatic surroundings with land-drainage or erosion from the adjacent pesticide-treated agricultural lands and tidal marshes. Considering the potential role played by JH analogs as insecticides, it seems of particular interest to determine whether these compounds may affect crustaceans, generally accepted to be closely related to insects.
