The objective of the present invention is to provide a new antifeedant. The other objective of the present invention is to provide a NMU derivative showing a high antifeedant activity even in common administration forms such as peripheral administration. A neuromedin U derivative wherein a methoxypolyethylene glycol is bound via a linker having a specific structure to a polypeptide which contains at least 8 amino acids of the C-terminus of an amino acid sequence of neuromedin U and which consists of the same or substantially the same amino acid sequence as the amino acid sequence of neuromedin U.
