	Pesticides are a major cause of the reduction in the global amphibian population. In this study, the acute toxicity and chronic effects of metamifop on Xenopus laevis (X. laevis) tadpoles were investigated. The 96 h-LC50 value of metamifop on X. laevis tadpoles was 0.634 mg/L, which indicated that '''metamifop was highly toxic to tadpoles'''. In the chronic toxicity study, tadpoles were exposed to 0.063 mg/L of metamifop. After 14, 21 and 35 d of exposure, '''metamifop significantly inhibited the body weight and neurotransmitter synthesis of tadpoles''', '''caused abnormal behavior and interfered with fat metabolism'''. According to the results of antioxidant enzymes and malondialdehyde (MDA), tadpoles exposed to 0.063 mg/L metamifop suffered severe lipid oxidative damage. Compared with the control group, the '''thyroid hormone (TH) levels and related gene expression in tadpoles in the treatment group were affected, reflecting the endocrine interference effect of metamifop'''. The data of this study can enrich our knowledge of the effects of aryloxyphenoxy propionate pesticides on amphibians and highlight the role of metamifop and other pesticides play in global decline of amphibians.

			'''Abstract''':
			Pesticides are a major cause of the reduction in the global amphibian population. In this study, the acute toxicity and chronic effects of metamifop on Xenopus laevis (X. laevis) tadpoles were investigated. The 96 h-LC50 value of metamifop on X. laevis tadpoles was 0.634 mg/L, which indicated that '''metamifop was highly toxic to tadpoles'''. In the chronic toxicity study, tadpoles were exposed to 0.063 mg/L of metamifop. After 14, 21 and 35 d of exposure, '''metamifop significantly inhibited the body weight and neurotransmitter synthesis of tadpoles''', '''caused abnormal behavior and interfered with fat metabolism'''. According to the results of antioxidant enzymes and malondialdehyde (MDA), tadpoles exposed to 0.063 mg/L metamifop suffered severe lipid oxidative damage. Compared with the control group, the '''thyroid hormone (TH) levels and related gene expression in tadpoles in the treatment group were affected, reflecting the endocrine interference effect of metamifop'''. The data of this study can enrich our knowledge of the effects of aryloxyphenoxy propionate pesticides on amphibians and highlight the role of metamifop and other pesticides play in global decline of amphibians.

=='''[[metamifop]]'''==
Metamifop is a 2-{4-[(6-chloro-1,3-benzoxazol-2-yl)oxy]phenoxy}-N-(2-fluorophenyl)-N-methylpropanamide that has R-configuration.

It is an inhibitor of acetyl-coenzyme A carboxylase (ACCase) and a postemergence herbicide which exhibits high control efficacy against sensitive weeds, especially Echinochloa crus-galli in paddy fields.

It has a role as an EC 6.4.1.2 (acetyl-CoA carboxylase) inhibitor and a phenoxy herbicide. It is an enantiomer of a (S)-metamifop.
