Herein disclosed is an annular sustained release pheromone-dispenser which has a shape favorable for packaging and transportation, can easily be installed, can maintain its installed condition over a long time period and can easily be handled even after use without any trouble. Also provided is a tool for easily and rapidly installing a pheromone-dispenser at elevated spots of, for instance, fruit trees.The sustained release pheromone-dispenser comprises a plurality of plastic tubes2aand2barranged in parallel and capable of being semi-resiliently deformed, whose ends3are connected together by fusion and whose central portions are independent and can form a annular space therebetween by pulling them apart from one another; and a liquid synthetic sex pheromone1enclosed in these plurality of plastic tubes2a, 2bwithout impairing the pheromone-release capacity. The tool37for installing an annular sustained release pheromone-dispenser has hooks32for attaching or detaching the annular sustained release pheromone-dispenser which are pulled apart from each other. The hooks32are positioned on both upper ends of the wire and the lower end38of the wire is secured to the top end of a rod33.
