ABSTRACT:
The invention provides a dispenser form for substainedly releasing vapor of a sex pheromone compound of pest insects with an object to control the population of the insects. The invention dispenser is characterized by the features that: the capacity thereof is sufficiently large to contain at least 100 mg of the pheromone; the barrier wall thereof through which the pheromone permeates to be released from the outer surface is made of a polymeric material swellable with the pheromone in an equilibrium swelling of 2-6% by weight at 20.degree. C.; and the outer surface area S thereof given in mm.sup.2 is sufficient to give a ratio S/W, W being the amount of the pheromone contained therein given in mg, in the range from 4 to 11. The rate of pheromone emission from the dispenser is relatively constant at 0.6 mg/day or larger over a long period of time of, for example, 3 months or longer.
