We observed the histopathological effects of several doses of cyphenothrin. Adult guppies (Lebistes reticulatus) were placed in water containing 34.8, 46.5, 53.5 or 60 micrograms cyphenothrin/L for 96-h and their gills examined. The most common changes at all cyphenothrin doses were the lifting of the epithelial layer from gill lamellae and some necrosis. Degeneration of secondary lamellae due to edema, the shortening of secondary lamellae, and club-shaped lamellae were also observed. The 96-h LC50 for cyphenothrin to Lebistes reticulatus was 48.7 micrograms/L.
我们观察了几种剂量的苯醚氰菊酯的组织病理学效应。将成年孔雀鱼（孔雀鱼）置于含有34.8、46.5、53.5或60微克苯醚氰菊酯/升的水中96小时，并检查它们的鳃。在所有苯醚氰菊酯剂量下最常见的变化是鳃小片上皮层的抬起和一些坏死。还观察到由于水肿导致的次生鳃小片退化、次生鳃小片缩短以及棒状鳃小片。苯醚氰菊酯对孔雀鱼的96小时半数致死浓度为48.7微克/升。
