苯醚甲环唑（Difenoconazole）是一种三唑类农药，广泛用于水稻、蔬菜等农作物用于防治真菌类感染。苯醚甲环唑对海洋鱼类的毒性报道很少。采用环境浓度的苯醚甲环唑（0、1、10、100和1000ng/L）暴露黑点青鳉180天。探究苯醚甲环唑对黑点青鳉（Oryziasmelastigma）生殖和脂类代谢的影响。 苯醚甲环唑暴露导致雄性黑点青鳉性体比下降，并在1000ng/L组出现差异。苯醚甲环唑处理组的精子数目减少以及精原细胞和精母细胞数量增加。脑中促性腺素释放激素（sGnRH）、促黄体激素（LHβ）和促卵泡激素（FSHβ）mRNA的表达量在所有的处理组都呈现显著下降。精巢中的雄激素受体（...Difenoconazole is one of the most widely used triazole fungicides in the aquaticenvironment. However, effects of difenoconazole on marine fish of reproductive and lipid metabolism have not been adequately researched. In the present work, marine medaka were exposed to difenoconazole at environmental concentrations (0, 1, 10, 100 and 1000 ng/L) for 180 days. The effects on reproductive and lipid met...学位：理学硕士院系专业：生命科学学院_动物学学号：2162012115229
