Description

A kind of agent for preventing and controlling ectoparasite of animals
One, affiliated field
The invention belongs to a kind of desinsection, insect-proof agent in the livestock breeding animal, relate to a kind of control agent, particularly a kind of animal body agent for preventing and controlling ectoparasite.
Two, background technology
Ecotozoa mainly comprises monoids such as mite, tick and lice.Mite, tick and lice of a great variety, widely distributed, very serious to animal is very big to the animal husbandry economy influence.
Mite can endanger ox, sheep, pig, horse, dog, rabbit, fowl and many wildlifes, the positions such as skin, feather and air bag that it parasitizes animal can cause that the animal play itches, illnesss such as depilation and pachyderma, by the animal of mite parasitism, show as and become thin, dysphoria, can not normally take food and rest.Mite also secretes a large amount of toxin in parasitic processes, the digestion and absorption function of animal and the defence capability of body are reduced, and animal skin be full of cracks, hemorrhage secondary infection finally cause death when serious.The mite class can cause multiple infectious disease, and as propagating Richettsia, virus and bacteriosis, mite still is the intermediate host of Anoplocephalidae tapeworm.
Tick claims flat lice or ox louse again, is the epizoa that most of terrestrial vertebrates can both obligate be sucked blood.Comprise three sections: hard tick section, soft ticks section and receive tick section, wherein the most common, harm is hard tick section to the maximum.Tick is sucked host's blood, can cause animal uneasiness, anaemia when a large amount of parasitic, become thin, depauperation, the fur quality reduces and milk production under degradation.And also secrete a kind of neurotoxin in the process of sucking blood, the secondary bacterial infection is the disseminate media and the reservoir host of many pathogene.Can cause multiple piroplasmosis and some infectious disease of domestic animal.Lice to the harm of livestock and poultry not as mite, tick is big but volume also can have a strong impact on growing of livestock and poultry when parasitic, reduces its productivity.
Another kind of epizoa lice, though the harm of livestock and poultry is not had tick, mite is serious, and volume also can have a strong impact on growing of livestock and poultry when parasitic, and when livestock and poultry entered age campaign, a large amount of parasitic of lice can reduce its production capacity.
Because ecotozoa produces influence greatly to livestock breeding, harm is serious.So, be important process during livestock breeding is produced to the verminal control of livestock and poultry.At present, ectoparasiticide thing commonly used both at home and abroad mostly is chemicals, wherein a lot of kinds are big to animal toxicity, use the back that feed, the activity of animal are all had considerable influence, and big to the pollution of environment, the livestock products quality there is harmful effect, and long-term the use, epizoa has produced resistance to various medicaments wherein, suddenly waits to develop the agent for preventing and controlling ectoparasite of efficient, low toxicity, low-residual, solves the ectozoic difficult problem of preventing and treating in the livestock breeding.
Three, summary of the invention
The objective of the invention is to, provide a kind of height is imitated in insect protected, little to animal toxicity, the agent for preventing and controlling ectoparasite of animals of environmentally safe.
The present invention to the epizoa activity research, filters out plant resource material rotenone by multiple biogenic active substance, these two kinds of reactive compounds of microbial source material Avermectin, studies show that, these two kinds of materials are to epizoa preventive effect height, and are little to animal toxicity, environmentally safe.
Rotenone is a contained active component in trifoliate jewelvine, the Baptisia plant, is used for the control of plant insect and mite more, and the report of application is not also arranged in preventing and controlling ectoparasite of animals.Avermectin is to be got by microbial fermentation, and they are many in preventing and controlling ectoparasite of animals to use with the hypodermic injection method, because hypodermic injection is big to the animal influence, after the injection Avermectin, just can slaughter after 3 months, so its application is subjected to certain restriction.
Rotenone, the Avermectin compound formulation of this research invention are used the be mixed principle of synergy of Pesticidal products, adopt the preparation processing means, make this compound formulation formulation reasonable, easy to use, use the back that feed, the activity of animal are not all had influence.On conceived sheep body, carry out body surface spray, wipe deeply, conceived sheep has no adverse reaction.Show epizoa is killed efficiently, animal is not had influence, the characteristics that environmental pollution is little.
The technical scheme that the present invention takes is: this agent for preventing and controlling ectoparasite of animals, be characterized in, and be effective ingredient with rotenone, Avermectin, add solvent, materials such as surfactant are mixed and form, and the percentage by weight of each component is:
Rotenone 0.1%~99.0%
Avermectin 0.0~2.0%
Solvent 50.0%~80.0%
Surfactant 5.0%~20.0%
This agent can be made into missible oil or aqueous emulsion, and converting water during use becomes emulsion, and spray quinoline or wipe deeply in the infected animal body surface parasitizes the various parasites such as tick, mite, lice of animal body surfaces such as pig, ox, sheep, rabbit with control.
Solvent for use can be water or deionized water or methyl alcohol in the preparation processing, or ethanol, or propyl alcohol, or one or more mixtures in the material known altogether of ethyl acetate or this area staff; Surfactant is a polyoxyethylene nonylphenol ether, or detergent alkylate sulphur phenol calcium, or the alkyl polyoxyethylene ether phosphate, or alkyl polyoxypropylene ether phosphate, or one or more mixtures in the speciality known altogether of polyoxyethylene nonylphenol ether phosphate or this area staff.
