An object of the present invention is to provide a new insecticidal compound by paying attention to the insecticidal activity contained in the flower part of marigold, and to provide an insecticide containing the compound as an active ingredient. There are provided an insecticidal compound represented by the following chemical formula: [Formula 1], and an insecticide containing the insecticidal compound as an active ingredient or an insecticide containing, as active ingredients, the insecticidal compound and an insecticidal compound represented by the following chemical formula: [Formula 2], wherein the insecticide can exhibit extraordinary insecticidal efficacy compared with existing pyrethroid-based insecticidal compounds. 

Insecticidal compound

A cartridge for insecticide transpiration includes an annular hollow structure which has openings in the inner peripheral surface and an outer peripheral surface thereof; a core portion situated at the center of the hollow structure for connecting to the rotation support shaft; a plurality of spoke portions connecting the core portion and the hollow structure; and blade portions integrally formed with the hollow structure so as to extend from the inner peripheral surface toward the center thereof and adapted to promote passing of air from the inner peripheral surface to the outer peripheral surface of the hollow structure, and; an insecticide transpiration apparatus wherein a cartridge for insecticide transpiration accommodating granular chemical-impregnated materialin the hollow structure is connected to a motor through the rotation support shaft and the cartridge for insecticide transpiration. The insecticide transpiration apparatus make it possible to maintain a stable transpiration performance for a long period of time.

Insecticide transpiration apparatus

There is provided an insecticide transpiration apparatus capable of transpiring insecticide at room temperature. The apparatus includes an apparatus main body having a recipient recess capable of accommodating an insecticide cartridge, an insecticide cartridge rotatably supported in the recipient recess, a driving means which is composed of a motor connected to a rotation support shaft of the insecticide cartridge and an electric source and which is contained in the apparatus main body, and a cover pivoted to the apparatus main body so as to cover the insecticide cartridge in the recipient recess, wherein the insecticide cartridge includes an annular hollow structure which accommodates granular insecticide-impregnated bodies and which has openings in an inner peripheral surface and an outer peripheral surface thereof, a core portion situated at the center of the hollow structure and connected to the rotation support shaft, a plurality of spoke portions connecting the core portion and the hollow structure, and blade portions integrally formed with the hollow structure so as to extend from the inner peripheral surface toward the center thereof and adapted to promote passing of air from the inner peripheral surface to the outer peripheral surface of the hollow structure.
