Abstract

Abstract There are disclosed solid formulations containing, as an active substance, a sex pheromone; as main vehicles, a carrier having absorbing properties and another carrier having adsorbing properties, and, furthermore, a wetting agent, a dispersant, a sticker, an ultraviolet (U.V.) stabilizer, an antioxidant and, optionally, a film-forming resin. Such formulations are utilized to control insects. In particular, the disclosed formulations contain, as an active substance, a sex pheromone of insects and, as a main vehicle, a mixture composed of a carrier having absorbing properties, and of another carrier having adsorbing properties, and are utilized to prevent insects from mating (mating disruption).
