Abstract: Provided is a chemical agent vaporizing/discharging device which can efficiently vaporize and discharge a chemical agent from a chemical agent retainer, and sufficiently diffuse the chemical agent, even when the device is used in a relatively large space or outdoors. A chemical agent vaporizing/discharging device 100 comprises: a chemical agent retainer 50 having a chemical agent retention layer 10 including interstices 11 for allowing retention of a volatile chemical agent, and a gas permeable layer 20 including voids 21 having a size larger than a size of the interstices 11; and a rotational drive part 60 for driving the chemical agent retainer 50. A shape and a size of the chemical agent retainer 50, and a rotational speed of the rotational drive part 60, are set so that a centrifugal effect of 10 to 150 (G) is obtained during rotation of the chemical agent retainer 50.

Abstract: Provided is an insect pest control product capable of effectively controlling flying insect pests. An insect pest control product comprising a thermal vaporization/diffusion absorbent wick for vaporizing and diffusing a water-based insecticidal composition containing a pyrethroid insecticidal component having a vapor pressure of 2×10?4 to 1×10?2 mmHg at 30° C., a glycol ether compound and/or glycol compound having a boiling point of 150-300° C., and water, wherein a concentration of the pyrethroid insecticidal component in diffused vapor particles one hour after the start of vaporization and diffusion is 1.5-18 times as high as a concentration of the pyrethroid insecticidal component in diffused vapor particles immediately after the start of vaporization and diffusion.

Abstract: A three-dimensional structure is provided which is obtained by molding a volatile chemical-containing resin composition into a plate form, wherein the three-dimensional structure includes through-holes penetrating therethrough from the front to the back thereof, the through-holes have peripheries having a shape selected from polygonal, circular, circular arc and spiral shapes when the three-dimensional structure is viewed from the front, and the peripheries of the through-holes are formed on a single plane or on a smoothly curved imaginary surface.

Abstract: Provided is an insect pest control product that is applicable to a water-based insecticidal composition and can continue to exert stable performance over a long period of time. The insect pest control product comprises a thermal vaporization/diffusion absorbent wick for vaporizing and diffusing a water-based insecticidal composition containing a pyrethroid insecticidal component having a vapor pressure of 2×10?4 to 1×10?2 mmHg at 30° C., a glycol ether compound and/or glycol compound having a boiling point of 150-300° C., and water. The thermal vaporization/diffusion absorbent wick has an insecticidal component/compound condensation ratio (P1/P2) within the range of 1.2-6.
