The sustained release pheromone formulation comprises a first sheet part and a second sheet part which are provided by bending a single polymer sheet so that they are arranged in a face-to-face manner, the sheet parts each having an engaging hole therethrough； a bend part located between the sheet parts； at least one sex pheromone substance that is carried on at least a part of the sheet parts； and slits each extending from the bend part to the engaging hole in each one of the sheet parts. This formulation can be secured to the rod-shaped support by guiding the rod-shaped support to the engaging holes via the slits and engaging with the holes. 20
