Organophosphate insecticide with pirimiphos-methyl (no longer in production)

Pirimiphos-methyl is a phosphorothioate used as an insecticide. It was originally developed by Imperial Chemical Industries Ltd., now Syngenta, in 1967.[1]

This is one of several compounds used for vector control of Triatoma. These insects are implicated in the transmission of Chagas disease in the Americas.[2] Pirimiphos-methyl can be applied as an interior surface paint additive, in order to achieve a residual pesticide effect.

Pyrimiphos-ethyl is a related insecticide in which the methyl groups are replaced with ethyl groups.
