Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pet animal such as a dog and a cat, or an external parasite such as cattle, pigs, chickens and other livestock and poultry, which controls ectoparasites such as fleas, mosquitoes and mites. It relates to a parasite control agent.

[0002]

2. Description of the Related Art In general, parasite insects such as fleas, ticks and other arthropods are often infested on the skin of animals, especially for pets such as dogs and cats and other mammals. Since animal skin contains hair and sebaceous glands or sweat glands, or both, such skin surfaces provide a habitat for fleas and mites. Animals, such as mammals and birds, on which a large number of parasites have propagated on the skin, have a severe decrease in immunity and other physical weaknesses, and have a high probability of being infected with various pathogenic bacteria and dying of disease.

[0003] In addition, if fleas and mites parasitize small pets that live in the same living environment as humans, they will not be clean and hygienic, so ectoparasites such as fleas and mites pesticides. Pesticides are used as appropriate.

[0004] Japanese Patent Application Laid-Open No. 3-41010 discloses an example in which an essential oil extracted from a plant is used for controlling ectoparasites in animals by kneading any one of cinnamon oil, pimenta oil, anise oil and cinnamon leaf oil into the resin. It is disclosed that pests are controlled by mounting the molded product on an animal or spraying the animal as an aerosol. Belgian patent 902977 discloses that a shampoo formulation containing linalool can be used as an ectoparasiticide for animals. Further, U.S. Pat.
No. 93986 discloses that a mixture of peni royal, eucalyptus, cedar oil, citronella and roux can be applied as a dust or spray to control fleas parasitic on animals. JP-A-11-322506 discloses controlling fleas with a sheet preparation, a spray, a powder, or the like in which cedarwood oil is mixed with an insecticide.

[0005] A liquid preparation which is an ectoparasiticide for animals and which is used by dripping locally on the surface of the animal body includes:
Fipronil preparations (trade name; front line), fenthion preparations (trade name; Tighorn Spot), imidacloprid preparations (trade name; advantage), and the like are known.

[0006]

As methods for controlling ectoparasites of animals, sprays, powders,
Although shampoos and the like are known, in order to treat the animal body and spread the active ingredient over the entire body surface of the animal, the treatment work is very burdensome because the animal dislikes or escapes. .

[0007] A treatment method which is expected to reduce the burden of the treatment operation is the use of a topical application agent to the surface of the animal body, and the above-mentioned fipronil preparations and the like are known. However, since these insecticide components are transdermally taken into the body of animals, these drop-type parasite control agents make the animals inactive due to their side effects. There was a problem of becoming.

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

[0009]

The inventors of the present invention have studied a method for controlling ectoparasites in animals which is easy to operate and has few side effects on animals. The present invention was completed by finding a simple method of topical application in which is applied dropwise or linearly to the body surface of an animal.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The animals to which the ectoparasiticide for animals of the present invention is applied are terrestrial animals other than humans that have the potential to parasitize parasites such as fleas and mites on the skin. Animals, including mammals and birds, that can be bred by humans as livestock, poultry or companion animals, such as dogs, cats,
Cattle, horses, pigs, chickens and the like.

The ectoparasites to be controlled include, for example,
Cat flea ( Ctenocephalidesfelis ), dog flea ( Ctenoce )
phalides canis ), human flea ( Pulex irritans ), keops rat flea ( Xenopsylla cheopis ) and other insect pests, Haemaphysalis longicorni
s), Yamatochimadani (Haemaphysalis flava), Taiwan Kaku ticks (Dermacentor taiwanicus), Ixodes ovatus (Ixodesovatus), Schulz ticks (Ixodes persulcatu
s ), ticks such as ox tick ( Boophilus microplus ), house dust mites ( Ornithonyssus bacoti ), mites ( Dermany
ssus gallinae ) and mites ( Trombic
ula sp. ), bovine lice ( Haematopinus e)
urysternus ) and lice such as sheep lice ( Dalmalinia ovis ).

Examples of the essential oils of plant extract used in the present invention include Yarrow oil, bay leaf oil, column oil, cardamomdakin oil, cedar leaf oil, cinnamon leaf oil, cinnamon oil, citronella oil, clove oil, lemon Glass oil, geranium oil, hyssop oil, lavender oil, basil oil, oregano oil, perilla oil, pimenta oil, rosemary oil, spearmint oil, styrax oil, thyme oil, vetiver oil, peni royal oil, eucalyptus oil, etc. And preferably column oil, cinnamon leaf oil, cinnamon oil, oregano oil, pimenta oil, thyme oil, etc., and a kind of plant essential oil can be used alone. Or it may be used by mixing two or more kinds.

The external preparation in the form of a solution to be applied to the surface of an animal body can be used alone or diluted with a solvent for a plant-extracted essential oil.

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

The amount of the essential oil extracted from the plant in the external preparation in the form of a solution for controlling ectoparasites of animals of the present invention is 1 to 100% by weight, preferably 5 to 100% by weight.

The solution of the present invention for external use in the form of a solution may contain a stabilizer such as an antioxidant.

Culex pipiens pallens ,
Culex mosquitoes such as Culex tritaeniorhynchus and Culex quinquefasciatus ,
( Aedes aegypti ), Aedes albopictus and other Ades genus, Anopheles sinensis and other Anopheles genus, Diptera, Ascidians, Flies, Diptera pests such as flies,
Since it is a flying insect, it does not always parasitize the animal's body surface, but comes into contact with the animal's body surface for blood feeding. Mosquito contact is greatly reduced in animals treated with the pesticide according to the invention, and even with contact, blood sucking is inhibited.

Formulation Examples and Examples are described below.
The present invention is not limited to these examples.

[0019]

Formulation Example 1 An external preparation of Formulation Example 1 was prepared by mixing 70 parts of thyme oil and 30 parts of dimethylene glycol monoethyl ether.

[0020]

[Formulation Example 2] Using cinnamon leaf oil as it is,
This was used as an external preparation of Formulation Example 2.

[0021]

Formulation Example 3 50 parts of Pimenta oil, 1 part of BHT and 49 parts of kerosene were mixed to prepare an external preparation of Preparation Example 3.

[0022]

Example 1 Three cats (female, weighing 3 kg) were used as test animals, and 3 mL of the external preparation of Formulation Example 1 was applied to each cat.
Was directly dropped on the skin by scraping the coat on the back of the cat.
Dropping was carried out using a dropper at six locations at 0.5 mL per head. Next, these cats were infested with 20 adult cat fleas per cat, and 24 hours later, the state of the infestation of the cat flea was observed. As a result, the number of infested cat fleas was reduced for all cats, and a high effect was recognized. No abnormalities were observed in these test cats. <Criteria for test results> Twenty-four hours after the infestation of the cat fleas, the hair was combed with a flea comb and the number of fleas removed was counted, and the results were classified as follows. Highly effective 0 to 8 Somewhat effective 9 to 16 No effect 17 to 20

[0023]

When an ectoparasite control agent of the present invention is applied to an animal, the ectoparasite can be efficiently eliminated without side effects on the animal.
