After being left to stand for 24 hours to be exposed to the drug, the glass plate together with the ring containing the test insect was moved to another room and fed, and after 24 hours, the mortality rate of the test insect was determined.
• Mite repellent rate (%) [(number of invading mites in untreated area-number of invading mites in treated area) / number of invading mites in untreated area] x 100
• Adhesion rate of control components to the floor A 20 x 20 cm glass plate is evenly installed in the entire room at 6 to 8 locations on the floor of a room (area 10 m 2 ) with a closed volume of 25 m 3 and the test aerosol is used. Was fired in the center of the room a little diagonally upward and one shot. One hour after the spraying treatment, all the glass plates were taken out, the attached control component was washed out with acetone, and analyzed by gas chromatography. Based on the obtained analysis values, the ratio (floor surface adhesion rate) of the control component settled and adhered to the floor surface to the theoretical total amount of the control component injection within one hour after the injection treatment was determined. In addition, regarding the control component attached to the glass plate, the dispersion between the glass plates was analyzed to evaluate the diffusion uniformity of the spray particles. The results are shown in four stages of A, B, C, and D in order from the one with good diffusion uniformity.
• the sprayed particles spread almost uniformly over the entire floor surface, and up to 1 hour after spraying. It was confirmed that 60% or more of the control components settle and adhere to the floor surface. Further, when the pests of Examples 1 to 16 and 20 to 24 containing the compound for controlling crawling pests and the aerosol for controlling ticks are used as the less volatile control component, the crawling pests and indoor dust mites are used. It was confirmed that an excellent control effect was exerted on any of the above. When the pests of Examples 17 to 19 and the aerosols for controlling ticks, which are mixed with a compound for controlling ticks, are used as the hardly volatile control component, an excellent controlling effect for indoor dust mites can be obtained. confirmed.
• Comparative Examples 1 to 4 a sufficient control effect was not obtained against both the crawling pests and indoor dust mites.
• Comparative Example 1 since the aerosol containing only the room temperature volatile pyrethroid compound such as empentrin was used as the control component, the floor adhesion rate was reduced, and as a result, the control effect is considered to be low.
• Comparative Example 2 since the fixed amount injection valve having an injection capacity of 0.4 mL was used, the control component to be injected did not reach the required amount with one push, and as a result, the control effect was considered to be low.
• the pest and mite control method and the pest and mite control aerosol of the present invention can be used not only indoors but also for a wide range of pest and mite control.
