    • An improved insect-combatting device (e.g., for use against houseflies, gnats and mosquitoes) is disclosed. The device comprises a shaped solid body having a porous surface capable of gradually and continually releasing naled insecticide in an amount sufficient to provide an insecticidally active concentration of said naled over a prolonged period of time and comprises a synthetic resinous matrix material, from about 15 to about 35 weight percent of naled and a minor amount effective to retard spewing of the insecticide of finely divided silica particles and at least one C.sub.14 to C.sub.20 saturated aliphatic carboxylic acid or a salt or ester thereof. The device is formed from a mixture of the said synthetic resin, naled, finely divided silica particles, C.sub.14 to C.sub.20 to aliphatic saturated carboxylic acid or salt or ester thereof and a surface porosity control component that is non-reactive in the mixture and has a boiling point at or below the curing temperature to produce surface openings in communication with pores in said body by vaporization of said porosity control component to provide the release of naled gas at a rate effective to control insects in the vicinity of said body, but insufficient to form as spew on the body.
    • 公开了一种改进的防虫装置(例如,用于家蝇,g蚊和蚊子)。 该装置包括具有多孔表面的成形固体,该多孔表面能够以足以在长时间内提供所述定向的杀昆虫活性浓度的量逐渐且持续释放定向杀虫剂,并且包括合成树脂基质材料,约15至 约35重量%的有效量的微量二氧化硅颗粒和至少一种C14至C20饱和脂族羧酸或其盐或酯的杀虫剂的喷雾有效。 该装置由所述合成树脂,定形,细碎的二氧化硅颗粒,C14至C20与脂族饱和羧酸或其盐或酯的混合物和在该混合物中不起反应性的表面孔隙率控制组分的混合物形成, 沸点等于或低于固化温度,以通过所述孔隙率控制组分的蒸发产生与所述主体中的孔连通的表面开口,以提供有效地控制昆虫在所述身体附近的速率释放定向气体,但不足以 形成为身体上的喷雾。
