ABSTRACT:
A sustained release pheromone-containing preparation is obtained by incorporating a sex pheromone having a heat of evaporation ranging from 21,000 to 27,000 cal/mole and a parameter, as a measure for the solubility, ranging from 8 to 9 cal.sup.1/2 cm.sup.-2/3 into powder of a synthetic resin, whose parameter, as a measure for the solubility, ranges from 8 to 9.5 cal.sup.1/2 cm.sup.-2/3, having an average particle size ranging from 0.2 to 2.5 mm. The sustained release pheromone-containing preparation can be sprayed using a widely used spraying machine and can release the sex pheromone at an almost constant concentration over a long period of time.
