DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest trap containing a poison bait.

[0002]

2. Description of the Related Art Generally, as a pest trap for indoor use, there is a box-shaped container made of paper or a plastic material containing a poison bait, a trapping adhesive, an attractant, and the like, and these are trapped indoors. Pests can be discarded together with the container without touching the user.

[0003] However, when the above-mentioned insect pest is used outdoors in a garden or a field for agriculture or horticulture, the paper-made one absorbs rainwater or condensed water and breaks or breaks.
Recovery became difficult, and even if it could be recovered, it was not uncomfortable and the entire container could not be disposed of. Further, there is a problem that the active ingredient of the poison bait exposed to direct sunlight or rainwater is easily denatured or lost outdoors, and the capturing effect is not maintained. On the other hand, a container molded from a weather-resistant plastic material, when used in large quantities for agriculture and horticulture, becomes a large amount of industrial waste after use, and there is a problem that its disposal is not easy.

[0004]

SUMMARY OF THE INVENTION As described above, when the pest catcher is used outdoors as described above, the paper trap is deformed and cannot withstand use because it is not made of paper because it has no weather resistance.
Resolves the problem that weather-resistant plastics do not decompose even after many months and are not easy to handle artificially.The pest catchers used outdoors have weather resistance for the required period and are housed. It is an object of the present invention to suppress the denaturation of the active ingredient of the prepared poison bait, to dispose of the entire container without discomfort after use, and to prevent the container itself from becoming a problem as industrial waste.

[0005]

In order to solve the above-mentioned problems, the present invention employs a structure in which a microbiologically decomposable plastic top-opening container contains an edible edible bait.

Further, a plastic cover of the same quality as the container may be attached above the opening of the container. The container may be provided with a cylinder penetrating the bottom surface and protruding upward, and a configuration in which a fixing pin is inserted into the cylinder may be adopted, and the poison bait may contain a slug-killing slug component. It may be an active ingredient.

[0007]

The pest trap of the present invention has a high trapping efficiency because the pests gathered on the attracting poisonous bait easily penetrate through the opening on the upper surface, and rainwater penetrates until the container is decomposed by microorganisms. Without drying, it is resistant to drying and retains the required shape. The container after capturing the pest can be discarded without discomfort, but it is assimilated by microorganisms and disappears even when left outdoors. Further, the cover above the container opening prevents direct sunlight and rainwater from entering the container, so that the poison bait can work effectively for a long period of time and the trapping efficiency is good. If the fixing pin is inserted through the cylinder attached to the bottom surface of the container, the container is fixed to the ground or the like, and does not fall down due to the wind.

[0008]

Table 3 to Table 6 show the results of comparison with the case where the poison bait was placed in any one of the containers or only the poison bait of each experimental example was sprayed.

Experimental Example 1: 5% by weight of yeast powder, 10% by weight of flour, 0.5% by weight of sodium dehydroacetate, 0.01% by weight of Blue No. 1, 4% by weight of carrageenan and 74.49% by weight of water at 60 ° C. After mixing 6% by weight of methaldehyde, the mixture was poured into the container 1 shown in FIG. 1 to obtain a pest trap containing a slug-killing agent.

Experimental Example 2: Skin milk 5% by weight, cane sugar 10% by weight, sodium dehydroacetate 0.5% by weight, carrageenan 4% by weight, sorbitan monooleate 1% by weight
27.5% by weight of fenitrothion was added to a mixture of 77.5% by weight of water and 77.5% by weight of water while heating at 60 ° C.

EXPERIMENTAL EXAMPLE 3 A mixture of 5% by weight of skin milk, 10% by weight of cane sugar, 0.5% by weight of sodium dehydroacetate, 4% by weight of carrageenan and 75.5% by weight of water at a temperature of 60 ° C. After mixing 5% by weight of fenitrothion microcapsules, 10 g of this mixture was poured into a container 10 shown in FIG. 3 to obtain a pest trap containing a pesticide.

Experimental Example 4: Water was kneaded with 6% by weight of methaldehyde, 5% by weight of yeast powder, 0.5% by weight of sodium dehydroacetate and 88.5% by weight of flour and kneaded. × A granular slug killer having a length of 10 mm was obtained and stored in the container 1 shown in FIG. 1 to obtain a pest trap.

Experimental Example 5: Water was added to 5% by weight of skin milk, 10% by weight of cane sugar, 0.5% by weight of sodium dehydroacetate, 2% by weight of fenitrothion and 82.5% by weight of flour, kneaded, and extruded. A granular insecticide having a diameter of 1 mm and a length of 2 mm was obtained by a granulator, and this was placed in a container 1 shown in FIG.
0 and used as a pest trap.

With respect to Experimental Examples 1 to 5 and Comparative Examples 1 to 5 in which the bait was applied in the same amount without being put in a container, the trapping efficiency against slugs or German cockroaches was examined by the following method.

(1) Evaluation for slugs A pest catcher (containing 50 g of poison bait) was placed in a mushroom field of 9 m ^2.
Per day, or the same amount of poison bait was sprayed, and after one day, the number of slugs evicted was 51 or more (++++).
Mark), 31 to 50 (++ mark), 11 to 30 (+ mark)
And a four-point scale of 0 to 10 animals (-).

(2) Evaluation of German cockroaches A 50-year-old adult German cockroach (same male and female) was placed in a container having a bottom area of 0.12 m ² , and a pest catcher containing a poison bait or a poison bait without a container was placed in the container. 90% or more of mortality rate after 24 hours (++ mark), 80-90%
(+ Mark) and less than 70% (-mark) were evaluated on a three-point scale.

Capture results for slugs:

[Table 6]

As is clear from the results of Tables 3 to 6,
In the case where only the poison bait was used without the container, the capturing effect of the poison bait such as German cockroaches was significantly reduced after 3 days with the slug killer and after 2 weeks. With the pest traps of Examples 1 to 5, efficient trapping was possible for a long time, and there was no unclean feeling when discarded.

[0045]

According to the present invention, as described above, the poison bait contained in a biodegradable plastic container is not washed away or deteriorated during a period appropriate for capture, and the container is protected from rainwater or sunlight. With the cover and the pin for fixing, these effects are remarkable and installed outdoors and the capture efficiency is high.
Also, after its use, it can be easily collected and treated without discomfort or left as it is, so it will not be a problem as industrial waste even if used in large quantities for agricultural and horticultural purposes.
It can be said that it is of high use value.
