Description

The present invention relates to a spider egg sap treating agent for controlling spiders.

In recent years, the spider spider, a poisonous spider, is out of Japan and is feared because it can lead to death if stabbed. In addition, spider webs are often plagued by indoors, warehouses, trees, etc., and the appearance of the spider webs may be damaged or unsanitary. Therefore, various proposals have been made to use an insecticide to control spiders. For example, Japanese Patent Application Laid-Open No. 9-169609 (Patent Document 1) discloses a spider control agent containing pyrethroid imiprothrin, which can quickly control adult spiders. Japanese Patent Application Laid-Open No. 2008-162951 (Patent Document 2) describes a stock solution containing a pest control agent and silicone, and a spider nesting prevention aerosol containing a propellant. Rather than increasing the efficacy, silicone has been used in combination with the purpose of improving spreadability and smoothness at the sprayed spot and making it easier to remove the spider web. Although the proposals of Patent Document 1 and Patent Document 2 show certain effects for controlling spider adults and preventing spider nesting, satisfactory results are not always obtained.

On the other hand, a control technique for preventing hatching at the stage of eggs is known instead of targeting adult insects and larvae. For example, Japanese Patent Application Laid-Open Publication No. 2004-26777 (Patent Document 3) discloses an ovalicide containing a paraffinic hydrocarbon as an active ingredient for cockroaches and fiber pests, but it is evaporated in a sealed space. This is an application method that is not suitable for outdoor use. JP-A-2007-45813 (Patent Document 4) discloses that a cockroach preparation containing a compound having an oviposition-inducing action is orally ingested by an incubating cockroach and releases the egg outside the body. Techniques for killing eggs are described. However, this egg-killing method is intended only for adults and indirectly trying to obtain an egg-killing effect, and it is difficult to say that the effect is stable.

By the way, spiders are different from other species of pests, and eggs laid are covered with eggs. Due to the ecology peculiar to spiders, for example, according to Non-Patent Document 1, pyrethroid pest control components such as phenothrin and permethrin show high control effects against spiders, Has been reported to be ineffective. Therefore, in general, it is difficult to kill spider eggs with ordinary insecticidal aerosols, and at present, no spider egg processing agent has been developed that can provide an efficient ovicidal effect.
However, the present inventors blended a paraffinic solvent having a specific kinematic viscosity with a chemical solution for a spider egg processing agent, and adopted an optimum viscosity as a chemical solution for a spider egg processing agent. It came to invent the useful eggplant processing agent for spiders.

An object of the present invention is to provide a spider egg mushroom treatment agent having a high ovicidal effect on spiders and having excellent usability.

The present invention has been found that the following constitution has an excellent effect for achieving the above-mentioned object.
(1) (a) one or more selected from pest control ingredients having activity against arthropods, and (b) paraffin having a kinematic viscosity of 1.0 to 30 mm ² / S (40 ° C.) A chemical solution containing an organic solvent, wherein the viscosity of the chemical solution is 3 to 100 mPa · S / 20 ° C.
(2) (a) The spider eggplant treatment agent according to (1), wherein the pest control component having activity against arthropods is cyfluthrin.
(3) Further, (c) for spiders according to (1) or (2), which further contains a higher fatty acid ester compound of a higher fatty acid having 14 to 18 carbon atoms and a branched saturated alcohol having 14 to 18 carbon atoms Egg processing agent.
(4) The spider egg processing agent according to any one of (1) to (3), wherein a propellant is added to the chemical solution and filled in a pressure-resistant container to form an aerosol form.

The spider egg slaughter agent of the present invention is extremely practical because it has a high ovicidal effect against spiders and is excellent in usability.

In the present invention, (a) as a pest control component having activity against arthropods, for example, cyfluthrin, phthalthrin, phenothrin, permethrin, ciphenothrin, cypermethrin, tralomethrin, fenpropatoline, resmethrin, allethrin, praretrin, Pyrethroid insecticides such as flamethrin, imiprothrin, empentrin, transfluthrin, metfluthrin, profluthrin, etofenprox, organosilicon insecticides such as silafluophene, organophosphorus insecticides such as fenitrothion, malathion, dichlorvos, propoxl, carbaryl, etc. Carbamate insecticide ingredients, dinotefuran, imidacloprid, acetamiprid, thiamethoxam, neonicotinoid insecticide ingredients such as nitenpyram, fipronil, etc. Phenylpyrazole insecticides component, oxadiazole insecticidal component such as metoxadiazone the like. Above all, cyfluthrin is preferred because of its excellent insecticidal efficacy and durability.
Among such pest control components, there are optical isomers and geometric isomers based on the asymmetric carbon and double bond, and it is a matter of course that the use of each of these or any mixture thereof is also included in the present invention. is there.
If necessary, other kinds of pest control components may be added.

The content of the pest control component blended in the chemical solution used in the present invention may be appropriately determined in consideration of the purpose of use, the period of use, etc., but about 0.01 to 5.0 w / v% in the chemical solution is appropriate. It is. If it is less than 0.01 w / v%, the desired effect cannot be obtained. On the other hand, even if it exceeds 5.0 w / v%, there is no particular merit.

The present invention is characterized by combining the above-mentioned pest control component and a specific eggplant processing aid in achieving a useful spider egg processing agent.
Such egg yolk processing aids enhance the egg yolk permeability of the above-mentioned pest control ingredients and are required to have an appropriate viscosity. As a result of intensive studies, the present inventors have used a paraffinic solvent having a kinematic viscosity of 1.0 to 30 mm ² / S (40 ° C.), preferably 2.0 to 15 mm ² / S (40 ° C.). However, it is found that it is useful as a spider egg processing agent if the viscosity of the chemical solution combined with the pest control component is in the range of 3 to 100 mPa · S / 20 ° C. Is.
Examples of such paraffinic solvents include IP Solvent 1620, IP Solvent 2028 and IP Solvent 2835 manufactured by Idemitsu Petrochemical Co., Ltd., Isopar H, Isopar L and Isopar M manufactured by Exxon Chemical Co., Ltd., and Isosol manufactured by Nippon Oil Corporation. Isoparaffins such as 300 and Isosol 400, neothiozole manufactured by Chuo Kasei Co., Ltd.,
Normal paraffins such as Solvent H manufactured by Nippon Oil Co., Ltd. are exemplified, but not limited thereto.
In the present invention, isoparaffin is preferable to normal paraffin. Usually, the use of a normal paraffin solvent is more general, but as a result of the study, in terms of egg yolk permeability and compatibility with higher fatty acid ester compounds described later, the carbon number is particularly 10 to 10. A 16-based isoparaffinic solvent has been found to be optimal for the purposes of the present invention.

The blending amount of the paraffinic solvent to be blended in the chemical solution is suitably 40 w / v% or more in order to maintain the egg sac permeability of the pest control component. If it is less than 40 w / v%, the egg sac permeability is inferior and a sufficient ovicidal effect cannot be achieved.

In the present invention, (c) a higher fatty acid ester compound may be used as a further eggplant processing aid.
(C) As a higher fatty acid ester compound, an ester compound of a higher fatty acid having 14 to 18 carbon atoms and a branched saturated alcohol having 14 to 18 carbon atoms is preferable, and specifically, isocetyl stearate, isocetyl isostearate , Isostearyl palmitate, isocetyl myristate, and the like, but are not limited thereto. While these compounds are well compatible with paraffinic solvents, they have low volatility and maintain a liquid state at room temperature, thus contributing to an increase in sustainability of pest control components. Above all, isocetyl stearate is suitable for performance and easy to use.
The compounding amount of the higher fatty acid ester compound is suitably about 1.0 to 10 times the pest control component.

In addition, other organic solvents such as lower alcohols such as ethanol and isopropanol, propylene glycol, 1,3-butylene glycol, 1,4-butylene glycol, and diethylene glycol are used as long as the effects of the present invention are not hindered. , Glycols having 3 to 6 carbon atoms such as dipropylene glycol and hexylene glycol, these glycol ethers, ketone solvents, ester solvents and the like can be appropriately blended.

The spider egg processing agent of the present invention may be further mixed with water to form an aqueous aerosol agent. In this case, a surfactant or solubilizer is appropriately added as necessary. Examples of such surfactants include ethers such as polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, polyoxyethylene alkylamino ethers, polyethylene glycol Nonionic surfactants such as fatty acid esters, polyoxyethylene sorbitan fatty acid esters, fatty acid esters such as polyoxyethylene glycerin fatty acid esters, polyoxyethylene styrenated phenol, fatty acid polyalkalol amide, Anionic surfactants such as polyoxyethylene (POE) styryl phenyl ether sulfate, polyoxyethylene (POE) alkyl ether sulfate, and dodecylbenzene sulfate It is.
However, the compounding quantity of surfactant must be prescribed | regulated so that the viscosity of a chemical | medical solution may not exceed 100 mPa * S / 20 degreeC.

In addition to acaricides, fungicides, antibacterial agents and fungicides for fungi, fungi, etc., stabilizers, deodorants, antistatic agents, antifoaming agents, fragrances, excipients, etc. Of course, it does not matter even if it mix | blends suitably. Examples of acaricides include methyl 5-chloro-2-trifluoromethanesulfonamide benzoate, phenyl salicylate, 3-iodo-2-propynyl butyl carbamate, and the like. Examples include 2-mercaptobenzothiazole, 2- (4-thiazolyl) benzimidazole, 5-chloro-2-methyl-4-isothiazolin-3-one, trifolin, 3-methyl-4-isopropylphenol, ortho-phenylphenol, etc. it can.

In the spider egg processing agent of the present invention, a propellant may be added to the chemical solution and filled in a pressure-resistant container to form an aerosol form. As the propellant, dimethyl ether, liquefied petroleum gas (LPG), compressed gas (nitrogen gas, carbon dioxide gas, nitrous oxide, compressed air, etc.), or a mixed gas thereof is used. What is necessary is just to select shapes, such as a valve | bulb, a nozzle, and a nozzle, according to the objective etc. suitably. If an aerosol is used, it is very convenient because it can be used easily even in places that are hard to reach such as around fences and drains.
In the case of an aerosol agent, the viscosity of the aerosol content liquid can be lowered by blending dimethyl ether or LPG, but the propellant evaporates immediately after spraying. Therefore, it is the chemical solution that actually adheres to the spider eggs, and the viscosity used in the present invention is of course defined by the chemical solution before blending the propellant even if it is an aerosol.

The resulting spider egg processing agent of the present invention is treated outdoors around fences, drains, graveyards, eaves, air conditioner outdoor units, indoors, near the ceiling, near refrigerators, under the floor, etc. As a guide, about ² to 50 mL / m ² is appropriate. And according to this invention, the outstanding egg-killing effect can be acquired by processing directly on the spider egg. Even when treated with adult spiders, this agent has a high effect of killing insects and residual effect, and eventually leads to hatching prevention, which is extremely practical.

Examples of spiders that are the subject of the present invention include, but are not limited to, the red spider spider, joro spider, long-tailed spider, black spider spider, giant spider spider, and the spider spider. In addition, this agent has an excellent insecticidal effect against various insect species such as mosquitoes, chironomids, house flies, butterflies, fruit flies such as Drosophila, flying insects such as bees, cockroaches and ants. A wide range of applications is possible.

Next, based on a specific Example, the spider eggplant processing agent of this invention is demonstrated in detail.

Cyfluthrin 0.5 w / v% as a pest control component and isocetyl stearate 4.0 w / v% as an eggplant processing aid are isoparaffin [Product name: IP solvent 2028, kinematic viscosity: 2.6 mm ² / S ( 40 ° C.)] to prepare a chemical solution made up to 100 mL. The chemical solution had a viscosity of 17 mPa · S / 20 ° C. Thereafter, 90 mL of this chemical solution was put in a pressure vessel, and 210 mL of liquefied petroleum gas was charged under pressure as a propellant to obtain an eggplant treatment agent for spider eggs of the present invention in the form of an aerosol.
When we sprayed about 20 mL of this aerosol agent aiming at the red spider spider near the floor of a detached house and its surrounding area of about 2 m ² , the red spider spider quickly killed, and as a result of subsequent follow-up observations, spider eggs that existed nearby No larvae hatched from the end.

According to the chemical solution used in Example 1, various spider egg processing agents shown in Table 1 were prepared, and the tests shown below were conducted.
[Ovulation test]
A filter paper was laid on a glass petri dish with a diameter of 9 cm, and 10 eggplants on which the giant spider spawned were placed. 1 mL of the reagent solution was uniformly dropped on the eggplant and the hatching condition was observed until 6 weeks later. A result is shown by the hatching number in ten pieces.

As a result of the test, it contains a paraffinic solvent having a kinematic viscosity of 1.0 to 30 mm ² / S (40 ° C.) as an eggplant processing aid, and the viscosity of the chemical solution is 3 to 100 mPa · S / 20 ° C. The spider egg slaughter agent of the present invention showed a high ovicidal effect on spider egg sac. As the paraffinic solvent, isoparaffin is preferable to normal paraffin, and the compound of the ester compound of a higher fatty acid having 14 to 18 carbon atoms and a branched saturated alcohol having 14 to 18 carbon atoms is used as a pest control component. Since it contributes to the improvement of sustainability, it was more suitable. As a pest control component, it was also recognized that a pyrethroid compound such as cyfluthrin having higher residual effect was more advantageous than allesulin.
On the other hand, as shown in Comparative Example 1, the kinematic viscosity is 1.0 to 30 mm ² / S (40 ° C.) even in the case of solvents other than paraffinic solvents and paraffinic solvents as in Comparative Examples 2 and 3. Anything outside the scope of) was unsuitable. Further, Comparative Example 4 in which the viscosity of the chemical solution exceeded 100 mPa · S / 20 ° C. was also inferior in the ovicidal effect.
From these facts, by combining a pest control component and a paraffinic solvent having a kinematic viscosity of 1.0 to 30 mm ² / S (40 ° C.), and setting the viscosity of the chemical solution to 3 to 100 mPa · S / 20 ° C. It is clear that an extremely practical spider egg processing agent can be provided.

The spider eggplant treatment agent of the present invention can be used for the purpose of controlling a wide range of pests, both indoors and outdoors.
