JPH0227933A - Method for capturing and controlling land mollusk animal - Google Patents

Abstract

PURPOSE:To readily capture and control a land mollusk animal without giving damage to plants and scattering dead body of the animal by attracting the animal into a vessel by an attractant and simultaneously bringing the animal into contact with agent for killing the mollusk animal and/or preservatives. CONSTITUTION:An attractant for a land mollusk animal such as dried yeast, oil cake or sugar is arranged on the bottom surface of a vessel having ceiling face, wall face, bottom face and opening, e.g., a square or circular house type vessel, composed of foamed styrol, waterproofing paper, synthetic paper, etc., and an agent for killing the land mollusk animal such as metaldehyde and/or preservatives such as benzalkonium chloride are applied to the ceiling face and wall face.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for trapping and controlling terrestrial molluscs.

[Conventional technology]

Terrestrial molluscs such as slugs and snails have traditionally been problematic as animals that transmit parasites, damage agricultural crops, and cause discomfort.

Methods for controlling these terrestrial molluscs include (a) a method of directly spraying salt onto the animal body;

(b) A method of placing food poison scrapers containing metaldehyde, and (c) a method of spraying liquid shampoo or highly concentrated detergent on the molluscs.

[Problem that the invention seeks to solve]

However, method (a) requires spraying a large amount of salt to kill the plants by dehydration due to changes in osmotic pressure of the salt, and there is also the problem that plants may wither if they get on them. In method (b), carcasses were scattered around the area, making it dirty and unpleasant. Method (c), like method (b), involves the use of high concentrations, which can cause plants to wither, and both methods have problems such as restrictions on where they can be used.

[Means for solving problems]

Therefore, the present inventors have conducted extensive research on a method that allows anyone to easily capture and control terrestrial molluscs, and that can also be used to capture and dispose of molluscs without causing discomfort after treatment or treatment. Using a container containing an animal agent and/or preservative, attract terrestrial molluscs into the container with an attractant, and prevent them from escaping from the container by bringing them into contact with the molluscicide and/or preservative. We have discovered that this can be prevented and completed the present invention.

That is, the present invention is a method for trapping and controlling terrestrial molluscs by attracting and trapping them in a container consisting of a ceiling surface, a wall surface having an opening, and a bottom surface, wherein an attractant is placed on the bottom surface of the container and other surfaces are The present invention provides a method for trapping and controlling terrestrial molluscs, which comprises disposing a molluscicide and/or a preservative in the molluscicide.

The present invention will be explained in detail below.

The shape and structure of the container used in the present invention are not particularly limited as long as it is surrounded by a ceiling surface, a wall surface having an opening, and a bottom surface, but a rectangular or circular house-shaped container is preferable, for example.

The openings provided in the wall are entrances through which terrestrial animals are attracted to enter the container, and their number, shape, structure, etc. are not particularly limited.

Further, a roof portion may be provided to cover the device from light and wind and rain from above, or a transparent portion may be provided to allow viewing of the interior.

The material for the container may be appropriately selected from plastics, paper, wood, metal, etc., but styrofoam, urethane foam, waterproof paper, synthetic paper, etc. are particularly preferred.

In the present invention, an attractant is placed on the bottom surface of the container.

Such attractants are for attracting terrestrial molluscs into the container, and one or more of dry yeast, oil lees, rice bran, etc. are used as they are or mixed with grain flour or the like. The dry yeast is not particularly limited, and may be commercially available e.g. Ebios (manufactured by Epios Yakuhin Kogyo ■) or commercially available food for small animals mixed with grain, e.g. for laboratory animals.Although not particularly limited, dry yeast may be used for breeding insects (I: Made by Oriental Yeast)
, for mice (MF: manufactured by Oriental Yeast ■, CE-2: manufactured by Nippon Flare ■), etc. can be used.

As the oil cake, commercially available rapeseed oil cake, soybean oil cake, etc. can be used.

As for the bran, you can use raw bran, defatted bran, or roasted bran.

Each of the attracting substances can be used alone or in a mixed form in the form of a solid or paste, which can be sprayed on the inner bottom of the container as it is, or fixed with resin, glue, or the like.

Furthermore, in the present invention, a molluscicide and/or preservative is placed on the ceiling and wall surfaces of the container. Such molluscicides and preservatives are used to prevent terrestrial molluscs that have been attracted into the container from escaping out of the container by coming into contact with them. Examples of such preservatives include cationic active agents. Examples of disinfectants include benzalkonium chloride, benzethonium chloride, etc., and amphoteric active agents include lauryl aminoethylglycine, polyoctylaminoethylluglycine, alkyldimethylammonium betaine, and the like. In addition, tetrachloro inphthalonitrile,
2-(4-thiazolyl)-benzimidazole, N-nitroso-cyclohexyl-hydroxylamine metal, etc. alone or in combination, dissolved or suspended in water or a solvent, and used by applying to the ceiling and bottom of a container. be able to.

An example of a terrestrial molluscicidal agent is metaldehyde. This can also be applied and used in the same way as preservatives.

In the present invention, by placing an attractant on the bottom and applying a terrestrial molluscicide and/or preservative on the ceiling and walls, there is no need to sprinkle salt or highly concentrated detergent that can harm plants. In addition, it is possible to capture and control the carcasses of terrestrial molluscs without scattering them.

In other words, by simply placing a container, terrestrial molluscs can be guided into the container using an attractant without affecting surrounding plants or scattering dead individuals, and the attracted individuals can be placed inside the container to prevent them from escaping. By keeping the insects in place, anyone can easily and comfortably control them and dispose of them.

〔Example〕

Example 1 A truncated cone-shaped Styrofoam container with a bottom diameter of 15C1+, a height of 4.5cm, a ceiling diameter of 10CII, and four circular openings with a diameter of 31 on the wall was made, and the bottom surface of the container had the following surface. Place 1 g of each attractant shown in the table below with starch glue so that it does not fly off, and then grind each preservative and terrestrial molluscicide shown in the table below in a mortar on the other surfaces of the container, and add a small amount of water. In addition, it was applied in the form of a strip, dried, prepared, and placed in areas where terrestrial molluscs live. The results were checked after 24 hours.

As shown below, they were successfully captured and controlled.

Example 2 Bottom surface 160I square, height 4.5CIl, ceiling surface 13
Apply 1 part of roasted bran, 2 parts of Epios powder, and a small amount of starch paste as an attractant to the bottom of a resin-treated paper container with 4 cm square openings on the wall and 4 3C11 square openings on the wall. were coated with metal aldehyde and amphoteric surfactant W (laurylaminoethylglycine), and left for 48 hours in a 1 square meter rearing box in which 25 wild slugs were released. As a result, all 25 animals were trapped inside the container, and no unpleasant carcasses appeared outside.

〔Effect of the invention〕

The method of the present invention does not harm plants, does not scatter carcasses, can be easily and comfortably controlled by anyone, and can be disposed of, so it can be used to capture and control terrestrial molluscs. It is suitable as a method.
