Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external parasite such as fleas parasitic on the body surface of pets such as dogs and cats or cattle, pigs, chickens and other livestock and poultry, and external parasites such as mosquitoes and mites. Parasite control agent.

[0002]

2. Description of the Related Art In general, the skin of animals is often infested with fleas, mites and other arthropods which are parasitic insects, and especially of pet animals such as dogs and cats and other mammals. The presence of hair and sebaceous glands, sweat glands, or both on animal skin makes such skin surfaces a habitable environment for fleas and mites. Animals such as mammals and birds in which a large number of parasites propagate on the skin have a weakened immune system and other weakened physical strength, and are more likely to be infected with various pathogenic bacteria and die of illness. In addition, when fleas and mites parasitize pet small animals that live in the same living environment as humans, there is no sense of cleanliness and it is also a hygienic problem.Therefore, external parasite control agents such as flea / tick control agents should be used. Used as appropriate.

A liquid preparation for ectoparasite control of animals, which is used by locally dripping on the body surface of an animal,
Fention preparations (trade name; Chiguhonspot) and the like are known.

[0004]

As a method for exterminating ectoparasites of animals, sprays, powders, shampoos, etc. are known, but they are applied to the whole body surface of an animal by treating them with the active ingredient. In order to spread the animals, the processing work is very burdensome because the animals dislike or escape.

A treatment method expected to reduce the burden of treatment work is the use of a topical application agent on the surface of an animal body, and the above-mentioned fenthion preparations and the like are known. However, the existing drip-type parasite control agents have insecticidal components that are transdermally taken into the animal's body, which causes the animal's movements to be inactive due to its side effects, and in extreme cases, the foot is flaky and difficult to walk. There was a problem that became.

An object of the present invention is to create an ectoparasite control agent for animals which is easy to use and has few side effects on animals.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted earnest researches on the idea that an insecticidal ingredient derived from a natural product or an ingredient having pest repellent activity is effective for an animal as an active ingredient capable of easily controlling ectoparasites. The inventors have found that a mixture of pyrethrum extract extracted from pyrethrum and plant essential oil is effective and completed the present invention.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The animal to which the ectoparasite control agent for animals of the present invention is applied is a non-human land animal that may parasitize the skin with parasites such as fleas and mites, Including mammals and birds, humans are animals that can be raised as livestock, poultry or pets, such as dogs, cats,
Examples include cows, horses, pigs, and chickens.

Oil, eucalyptus oil and the like, preferably columnus oil, cinnamon leaf oil, cinnamon oil, oregano oil, pimenta oil, thyme oil and the like, and the plant essential oil is alone May be mixed with pyrethrum extract, it may be used in admixture with pyrethrum extract two or more of the purified oil.

In order to enhance the effect of exterminating ectoparasites in animals, other pesticides or insect growth regulators may be added to the pesticide of the present invention.

Other insecticides that can be added to the ectoparasite control agent of the present invention include pyrethroid compounds, neonicotinoid compounds, phenylpyrazole compounds,
Examples thereof include phenylpyrrole compounds.

Examples of pyrethroid compounds include:
Examples thereof include allethrin, phenothrin, permethrin, transfluthrin, bifenthrin, etofenprops, silafluofen, cyfluthrin, cyhalothrin, pralethrin and the like.

Examples of neonicotinoid compounds include acetamiprid and nitenpyram.

Examples of insect growth control compounds that can be added to the ectoparasite control agent of the present invention include juvenile hormone-like compounds such as pyriproxyfen and methoprene,
Examples include chitin formation-inhibiting compounds such as dimylin, hexaflumuron, chlorfluazuron, rufenuron, diflubenzuron, teflubenzuron, triflumuron, flufenoxuron, and flucycloxuron, antijuvenile hormone-like compounds, molting hormone-like compounds, etc. In particular, the use of pyriproxyfen is preferred.

The ectoparasite control agent of the present invention applied to the surface of an animal body may be prepared by diluting a pyrethrum extract and a plant essential oil in a solvent, or a mixture of the pyrethrum extract and a plant essential oil may be used. can do.

Examples of the solvent include glycol ethers such as diethylene glycol monoethyl ether and diethylene glycol monomethyl ether, glycols such as ethylene glycol and propylene glycol, alcohols such as benzyl alcohol and ethyl alcohol, kerosene and propylene carbonate. Is mentioned.

Further, the ectoparasite control agent of the present invention may contain a fragrance, a spreading agent, a stabilizer, a synergist and the like. Examples of the stabilizer include dibutylhydroxytoluene (abbreviated as BHT), butylhydroxyanisole (abbreviated as BHA), and 4,4′-thiobis (3.
