Description

  TECHNICAL FIELD The present invention relates to mosquitoes and other pests, etc., which are prevented by the occurrence of water starch such as moths and grooves, and to prevent mosquitoes and other pests, etc. It is.

In recent years, mosquitoes, etc. have been mass-produced in newly developed residential areas, especially in the drainage channels and sewers of housing estates, and this has been a major problem for residents.
In addition, mosquitoes survive regardless of the water pollution, and harm the people who live there during this period.Further, the complete removal of pests that adversely affect mosquitoes and other human bodies may be adversely affected by the ingredients used. This is a semi-permanent solution.
Prevention of harm to residents by pests, particularly mosquitoes, is certainly a permanent problem, and a wide variety of solutions, methods, and structures are known.
For example, in Patent Document 1 below, a “mosquito net installation structure for rainwater traps” that prohibits the entry and exit of mosquitoes by placing a net between the lid of the rainwater trap and the main body is disclosed in Patent Document 2 above. "Rainwater basket" with a screen that allows rainwater to pass through and a discharge electrode at the bottom reservoir, Patent Document 3, "Mosquito rainwater tank" with a copper material at the required location where water stays, Patent Document 4 discloses a “drainage basin” in which an inner lid configured to dam up rainwater flowing in from the drain hole of the culm lid and be releasable by a gravitational force of a certain level or more is disclosed in Patent Document 5 as “insect repellent plate”. Each has been proposed.

Japanese Patent No. 3410082 Japanese Patent No. 4116906 JP 2000-154589 A Japanese Patent No. 3377515 JP 2006-22630 A JP 2006-129820 A

  However, the above-mentioned “Mosquito net installation structure for rainwater traps” has a risk of deterioration of the mosquito net due to the weight of the lid at the edge of the lid and the stepping pressure, and in addition, the size adjustment of the mosquito net is involved. In terms of the service life and installation work efficiency, “Rainwater dredge” is the amount of electricity used, fear of electric leakage, etc. “Mosquito rainwater dredge” is a large number of parts and the cost required for installation work. This is because a bulky device is installed inside to reduce the amount of saturated water inherent in the cocoon, and this device, screen, etc. are damaged by water pressure during heavy rain. The amount of water drainage during heavy rain in a small drainage hole that makes it impossible to enter and exit, and the `` Sanitary Pest Control Method '' does not take into account the level difference that occurs in the groove, such as net wear and tear, or the accumulation of water due to sludge , Each has left a problem.

  The present invention has been made in view of the above-mentioned problems of the prior art, and extinguishes bow flares, mosquitoes and other pests in a pool of water, such as a spear and a ditch, and drastically reduces the harm to the human body in the vicinity. With the goal.

Therefore, it is preferable to provide except for the fitting portions 51 and 61 between the lid 1 and the flange 5 and the groove 6, and suitable for the coating film 4. Strength and durability are required.
Furthermore, the volume of the coating film 4 and the amount of the insecticidal component 2 may be adjusted according to the period during which the coating film 4 gradually releases the insecticidal component 2, and at the same time, the insecticidal component 2 is prepared so as to be gradually released downward. By designing in this way, mosquitoes 9 and other adults that invade through the inflow hole 12 such as the larvae of the insect pests such as the bowfra 91 and the eggs 90 that flowed between the interiors of the drainage facility are disposed inside the drainage facility. It will kill you for a long time.

  In addition, when a greater killing power is desired, it is possible to increase the rate of continuous firing and increase the amount of insecticidal component 2 sustained release. Such insecticidal component 2 is a variety of varieties. It is optimal to use a pyrethroid component that has almost no adverse effects on the human body and has a large insecticidal effect.

FIGS. 2A and 2B show a second embodiment of the lid 1 such as a ridge or groove according to the present invention.
2 (a) and 2 (b) have a synthetic resin lid 1 provided with a coating film 40 continuously foamed on the inner surface 10 of the lid 1 of the synthetic resin cage 5 having no inflow hole portion 12, and FIG. 2 (a) is a plan view and FIG. 2 (b) is a cross-sectional view showing a drainage channel connecting a synthetic resin drainage gutter 5 and a synthetic resin non-porous pipe as a groove 6. is there.

  In such a water channel, the plastic non-porous tube is ruptured or the lid 1 is pushed up by the amount of water exceeding the clogging or saturation of the downstream part, and a water reservoir 80 is generated around the mosquito for easy spawning of the mosquito. There is a risk of gaps that allow access to mosquitoes 5 and mosquitoes, etc. Also, in large public sewers, when explosive water volume is created, a large new puddle is created in the vicinity, eggs of pests flowing from the upstream, It will provide an environment for the growth of the bow flares 91 and the spawning of the mosquitoes 9, and even under such circumstances, the lid 5 of the present invention, the lid 1 of the groove, etc. will allow the mosquitoes 9 to enter and exit and the spawning and growth of the bow flares 91 to occur. Prevent in advance.

  Also, the insecticidal component 2 may be already widely used, for example, an organic phosphorus compound, a carbamate compound, or the like, or an insect for reducing the next-generation pest density by sterilizing the attracted pests such as the mosquito 9 Growth control active ingredients such as juvenile hormone active compounds and chitin synthesis inhibiting compounds can be suitably used, and pyrethroid compounds can be optimally used.
