Beta cypermethrin is widely used in agricultural production and pest control in daily life. However, it is highly toxic to aquatic organisms. To explore the acute toxic effects of beta cypermethrin to zebrafish, the activity of total superoxide dismutase (total SOD), catalase (CAT), acetylcholin esterase (AChE), and related gene expression were measured after the exposure of beta cypermethrin. The results of acute tocixity test showed that beta cypermethrin is highly toxic to zebrafish, the symptoms of poisoning include curling, tic, faster flapping of operculum, weaker swimming ability, inter...
