Description

The present invention relates to a termite control container, a device, and a termite control method characterized by burying the device in the ground.

In order to control termites, a method of spraying insecticides on the soil under the floor of the building or directly treating the xylem that is damaged by termites is common. On the other hand, bait preparations have been favored in recent years due to the trend toward less chemicals and the ease of processing. A conventional bait preparation is generally a method in which termite baits such as wood are first stored in a plastic container and buried in the ground, and when termites are attached to the baits, they are replaced with bait preparations. (For example, Non-Patent Document 1)
However, in such a method, if the size of the hole on the surface of the container is large, not the target termites, but unpleasant pests such as gum worms, centipedes, slugs invade, and these pests prevent the entry of termites. There was a problem that. For these reasons, a termite control container, a termite control device, and a termite control method that can prevent the entry of unpleasant pests and allow only the target termites to invade are desired.

Journal of Economic Entomology, Vol.93, No.5, p1498-1507, Response of Reticulitermes spp. (Isoptera: Rhinotermitidae) in Northern California to Baiting with Hexaflumuron with Sentricon Termite Colony Elimination System, GALL M. GETTY, MICHAEL I. , KIRSTEN A. COPREN, and VERNARD R. LEWIS).

  It is an object of the present invention to provide a termite-controlling container, a termite-controlling device, and a termite-controlling method that can prevent invasion of unpleasant pests and allow only target termites to enter.

As a result of earnestly examining the termite control container, the termite control device and the termite control method that can prevent the entry of unpleasant pests and allow only the target termites to enter, the inventor has found that the longest diagonal line or the longest diameter of the hole Is a termite-controlling container characterized in that it has one or more holes with a surface area of 25 mm2 or less and a part or all of the container is transparent or translucent. By embedding a termite control device in the ground that contains a mixture of one or more insecticides that slowly kill termites by orally ingesting wood and termites, It was found that a high termite control effect is exhibited by blocking the entry of unpleasant pests and only the target termites enter.

As a specific shape of the termite control container having at least one hole having a longest diagonal line or a longest diameter of 5 mm or less and a surface area of 25 mm2 or less, a base containing a cellulose component A container that has a space that can contain one or a mixture of two or more insecticides (hereinafter referred to as food poisoning agents) that kill termites slowly by ingesting orally to wood and termites. There is no particular limitation as long as it is present, and examples thereof include a cube, a rectangular parallelepiped, a sphere, a cylinder, a rod, a cone, an egg, and a plastic bottle. It may be any shape as long as it has one or more holes whose longest diagonal line or longest diameter is 5 mm or less and whose surface area is 25 mm2 or less. , Semicircular, fan-shaped, egg-shaped, bowl-shaped, triangular, square, rectangular, trapezoidal, diamond-shaped, pentagonal, hexagonal, octagonal, star-shaped, etc. In addition, the shape of the hole is preferably a circle, an ellipse, a square, a rectangle, or a regular hexagon in terms of ease of manufacture and appearance.

Additives such as stabilizers, UV absorbers, colorants, antistatic agents, antioxidants can be added. Other than resin, glass or the like can also be used. In addition, as a material of a portion that does not need to be transparent or translucent, any material such as plastic, wood, paper, metal, ceramic, etc. may be used.

Examples of food poisons used in the present invention include insect growth regulators (pyriproxyfen, phenoxycarb, hydramethylnon, diflubenzuron, chlorfluazuron, hexaflumuron, triflumuron, bistrifluron, etc.), sulphuramide, boron compounds Etc. can be used singly or in combination of two or more. The base material containing the cellulose component is not particularly limited as long as it contains cellulose, and various pieces of wood, wood powder, paper, pulp, cellulose powder, and the like can be used as the base material. It can also be used by mixing. The concentration of the toxic agent impregnated in these substrates is 0.01% by weight or more and 20% by weight or less, and preferably 0.1% by weight or more and 5% by weight or less.

As a method of burying the termite control device of the present invention in the ground, a building, tree, timber, etc. to be protected from termites are specified, and 15 cm or more and 10 m or less, preferably 30 cm or more and 5 m or less around it. The termite control device of the present invention is embedded at an arbitrary depth from the ground surface to a depth of 100 cm.

  By burying the termite control container and the termite control device of the present invention underground, it was possible to show a high termite control effect.

Next, although it demonstrates still in detail according to a formulation example and an Example, this invention is not limited by these.
