Description

[Detailed description of the invention]

(Industrial Application Field) The present invention deals with damage caused by arthropods, molluscs, and reptiles (for example, damages caused by arthropods include cockroaches as vectors of pathogens, and termites causing damage to wooden main houses). Damage caused by molluscs includes bites and vectors of pathogenic bacteria caused by fleas, lice, ticks, etc., and damage to silk products caused by molluscs such as slugs and snails. There is damage to sprouts and vegetables.
This article relates to repellents for arthropods, molluscs, and reptiles to prevent damage caused by reptiles (including snakes shooting high-voltage cables). (Prior Art) Conventionally, as repellents for arthropods, there have been repellents containing diethyltoluamide, di-n-propyl isocincomeronate, dibutyl succinate, etc. as active ingredients. These repellents lacked long-lasting efficacy and were not suitable for long-term use. Therefore, these repellents are currently used as temporary repellents and have no repellent effect against molluscs and reptiles. As a repellent for molluscs, the only ones used are Shiunetsukenkorun and Nekoiru, which have paraformaldehyde as their main ingredient, but they lack a long-lasting repellent effect and are effective at repelling arthropods and reptiles. You can't get it. At present, it must be said that there are no reptile repellents available. As mentioned above, various repellents for arthropods and molluscs have been studied to date, but they lack long-lasting repellent efficacy and are common to arthropods, molluscs, and reptiles. There was no repellent that could be used against them. (Problems to be Solved by the Invention) In view of these circumstances, the present invention is capable of completely repelling all types of arthropods, molluscs, and reptiles, and exhibits its effectiveness for a long period of time. In addition, it is an object of the present invention to provide a repellent for arthropods, molluscs, and reptiles that is easy to use and inexpensive. (Means for Solving the Problems) In order to achieve the above object, the repellent for arthropods, molluscs, and reptiles of the present invention has the following formula: (R in the formula is an alkyl group or a phenyl group,
R' is H , R '' is H, and n is an integer of 1 or 2. As seen in No. 280723 "Animal repellent and its assembly" and 1985 patent application No. 035031 "Animal repellent", mammals such as dogs, cats, rats (excluding humans), pigeons, crows It was invented as a repellent for birds such as. However, this repellent for mammals and birds is effective against cockroaches, mites, termites, arthropods such as stains, slugs,
It was accidentally discovered that it exhibits excellent repellency against molluscs such as snails and reptiles such as snakes and lizards. Therefore, the chemical composition is completely different from conventionally known repellents for arthropods, molluscs, and reptiles. In addition, arthropods, molluscs, and reptiles are simply abbreviated as animals below. Specific examples of these glycol ethers include the following. CH3 _- O- _{CH2CH2 -} OH, _CH3-
( _{OCH2CH2 ) 2- OH} , C3H7 _-O -CH2CH2 _- OH _{, C3H7-} ( _OCH2CH2 ) _{2- OH} , _{C4H9 - O-}
CH ₂ CH ₂ −OH, C ₄ H ₉ − (OCH ₂ CH ₂ ) ₂ −OH, C ₆ H ₁₃ −
_{OCH2CH2 −} OH, _C6H13− ( _{OCH2CH2 ) 2} −OH _{, C2H5 -} O- _{C2H4 -} OH, _{C2H5 ( OCH2CH2 ) 2-} OH. These glycol ethers have a unique odor, and animals exhibit a significant repellent reaction to this unique odor. Please note that when selecting glycol ethers for use, the boiling point is 160℃.
The above is desirable. This is because glycol ethers with high boiling points do not cause discomfort to humans and have a long-lasting effect.
When water resistance is required, glycol ethers that are sparingly soluble or insoluble in water may be used. In actual use, a repellent containing glycol ethers as an active ingredient may be applied or sprayed. Incidentally, assemblies using glycol ethers are easy to use and have superior durability. This assembly product is one in which a porous carrier, an oil-absorbing material, and/or a resin contain a glycol ether represented by the general formula (). Specific examples of products containing glycol ethers include the following. Inorganic porous carriers include vermiculite, perlite, shirasu balloon, zeolite,
These include sepiolite, pumice, activated clay, kaolin, hydrotalcite, talc, snotex, bentonite, or diatomaceous earth. Examples of the organic porous carrier include activated carbon, pulp, fibrous materials, and synthetic resins. Examples of oil-absorbing materials include gelol (product of Shin Nippon Chemical Co., Ltd.), coaguillan (product of Ajinomoto Co., Ltd.), and 12-hydroxystearic acid. Natural resins include starch, casein, pine resin, dextrin, gum arabic, gelatin,
Examples include sodium alginate, gluten, agar, locust bean gum, guar gum alginate, gum tragacanth, or natural rubber latex. Synthetic resins include styrene butadiene rubber, polyvinyl chloride, polyvinyl acetate, ethylene vinyl acetate copolymer, fluoro rubber, polyimide, polyethylene,
Polystyrene, polyamide, polyester, polypropylene, phenolic resin, polyurethane,
Examples include melamine resin, urea resin, epoxy resin, polyvinyl alcohol, carboxymethyl cellulose, oligoester acrylate, cellulose acetate, or acrylic resin. The advantages of assembled products are ease of use, long-term durability, and the ability to select the form depending on the location of use. Assemblies contained in porous carriers can be prevented from scattering by spraying.
It can also be used in confined spaces. A material contained in a fiber material sheet, such as a viscose rayon sheet, can be used in places where coating or spraying is not possible.
Furthermore, in places where it cannot be sprayed but can be coated, it can be used as a paint containing resin. (Effects of the Invention) Since the animal repellent of the present invention has the above-mentioned structure, it has low toxicity and low volatility, and is safe during use and has great long-term efficacy.
The unique odor emitted by glycol ethers causes a significant repellent reaction in animals. Example 1 _C4H9- ( _OCH2CH2 ) _{2 -} OH _and

[Formula] is mixed in a weight ratio of 4:1, and then this mixed glycol ether is added to the coarse zeolite particles in an amount of 20% by weight.
Contain. Using this glycol ether-containing zeolite coarse particles, we attempted a cockroach repellent test. Place a paper box 20 cm long, 25 cm wide, and 5 cm high with open ends at both ends of the bottom of a glass aquarium measuring 40 cm long, 75 cm wide, and 30 cm high. A 5 cm x 5 cm piece of fried tofu was placed as bait in the center of both paper boxes, and 5 g of coarse zeolite particles containing glycol ethers were sprinkled around the bait in only one paper box. The glass aquarium was covered with netting to prevent the cockroaches from escaping and placed in dim darkness, and observations were made every 2 hours. The cockroaches used were 10 Yamato cockroaches and 10 black cockroaches, and the repellent effect was determined using the following formula. Repellency rate (%) = (Number of paper boxes with no repellent mixed in - Number of paper boxes with repellent mixed in) × 100 ÷ Number of paper boxes with no repellent mixed in. The repellency rate is 100% in the first observation, 100% in the second observation,
Third observation: 94.7%, fourth observation: 88.9%, fifth observation: 100%, average repellency rate = 96.72%.A repellent rate of 70% or higher is considered effective. Example 2 (CH ₃ ) ₂ CHCH ₂ −OCH ₂ CH ₂ −OH and C ₆ H ₁₃ −
After mixing with O--CH ₂ CH ₂ --OH at a weight ratio of 5:1, 0.1 cc of the mixed glycol ethers is collected with a pipette and dripped onto 1/4 of the filter paper to impregnate it. A filter paper impregnated with this mixed glycol ether is spread on the bottom of the chalet, 20 termites are placed inside, and the lid is placed so that the chaire is not completely sealed. Observation was conducted 24 hours later, and 20 of the animals died. Therefore, the test was repeated five times, and each time 20 termites died. Example 3 _C6H13- ( _OCH2CH2 ) _{2- OH and CH3-}
(OCH ₂ CH ₂ ) ₂ -OH in a weight ratio of 1:1, and then the polyester nonwoven fabric is impregnated with this mixed glycol ether in an amount of 5% by weight. This polyether nonwoven fabric containing mixed glycol ethers is designated as insect repellent specimen A. Next, a polyester nonwoven fabric impregnated with 5% by weight of C ₆ H ₁₃ -(OCH ₂ CH ₂ ) ₂ -OH is designated as insect repellent specimen B. Spread 150g of powdered feed for breeding mites (CE-2, Japan CLEA) for breeding mites on the bottom of a poly pad measuring 11cm high, 40cm wide, and 30cm long, and spread it as evenly as possible on top of this. Two sliced specimens (nonwoven fabric) were placed on each side. One of the left and right specimens is an insect control specimen, and the other is an untreated control specimen. On this specimen,
Place a container with a height of 1.4 cm and a diameter of 2.8 cm in the center containing 2.5 g of powdered feed (moisture 15%) containing no mites, and after one day count the number of mites that have crawled into the feed. Calculated using the saline flotation method. In the saline suspension method, after stirring the mite-infested feed well, take out 0.5 g of it, place it in a Wildman flask, suspend the mites using 20% saline, and suck out the upper layer of water. The mixture was transferred onto a filter paper equipped with a device, filtered, and the filter paper was stained with a 0.1% methylene blue aqueous solution. As a result of this operation, only the filter paper was stained blue, and the mites were not stained and appeared yellowish-white, so all the mites were counted under a stereomicroscope. Regarding the repellent effect, the repellent rate (%) was calculated using the following formula from the number of mites observed in the insect repellent specimen and the control specimen within the same polypad. A repellent rate of 70% or higher is considered effective. Repellent rate (%) = (Number of mites in control area - Number of mites in insect repellent area) ÷ Number of mites in control area x 100 The test was conducted at a room temperature of 25°C ± 2°C and a relative humidity of 70-80%.
