Provided is a water dispersion type sex pheromone sustained release preparation which makes it possible to suppress excess release at the initial stage of spraying and release a sex pheromone substance at a constant amount for a predetermined period, and which can be sprayed by using a common sprayer. Specifically provided is a water dispersion type sex pheromone sustained release preparation, comprising an insect sex pheromone substance which is enclosed in a ring of a cyclodextrin, an inclusion cyclodextrin which encloses the insect sex pheromone substance, a non-inclusion cyclodextrin which does not enclose the insect sex pheromone substance, a water-soluble polymer, and water. Furthermore, provided is a method for producing a water dispersion type sex pheromone sustained release preparation, comprising at least a step of mixing an aqueous suspension of an insect sex pheromone substance which is enclosed by a cyclodextrin, with a non-inclusion cyclodextrin which does not enclose the insect sex pheromone substance, and a water-soluble polymer.
