Ethiofencarb, classified as a phenyl methylcarbamate, is an organic compound characterized by the presence of a phenyl group esterified with a methylcarbamic acid. Its primary cellular localization is within the cytoplasm. The effectiveness of ethiofencarb as an insecticide stems from its capacity to impede acetylcholinesterase (AChE) activity. Additionally, it demonstrates inhibitory effects on other esterases. Notably, the carbamylation process, which occurs when ethiofencarb interacts with AChE, is transient and less stable compared to the phosphorylation observed with some other insecticides. As a result, the recovery of AChE functionality is relatively rapid.
