Description

Insecticides and with its control insect method
Technical field
The present invention relates to for preventing and treating the composition of insect, relate in particular to and kill epizoa activating agent (as insect growth regulator, IGR (Insect Growth Regulator, and the formula that pours (pour-on) composition of insecticide, and relate to the method for using described compositions-treated or control insect and parasite (especially preventing and treating insect or parasite on animal) IGR)).Particularly, the present invention relates to the pour formula composition of water-fast IGR in one or more of nonaqueous solvents.
Background technology
For animal doctor and poultry raiser, infecting of parasite on domestic animal (as flea) still representing not yet by the satisfied problem solving.
In the past, by multiple different measure, process animal, to prevent and treat insect and interior and epizoa.Also known the composition for the treatment of being infected animal is mixed with and is applied to zoodermic powder.Use this dusting conventionally not can by animal passivity accept because need a few minutes to process equably whole skin surface, and dust can inevitably arrive mouthful, nose and eye, causes animal discomfort or pain.Even in the process of using carefully, can not get rid of the possibility of animal and poultry raiser's inhalation of dust.Conventionally, the people who processes animal also can touch described composition in large quantities, and this is inevitably actually, and this contact can only be got rid of or be eliminated by time-consuming and difficult measure.
Also known the reagent for the treatment of being infected animal is mixed with to fluid composition.Can in many ways these fluid compositions be used for to animal.For example, by being immersed in, whole animal contains in the described fluid composition bath of (comprising effective parasiticidal medicament), or by the whole body surface with the spouted thing of described composition.In some cases, can not successfully use suitable fluid composition (shampoo as active in flea), because many animals (especially cat and many dogs) allow its poultry raiser have a bath to them or can only force, not carry out.In addition, the effect that this bathing is processed only continues limited a period of time (for example at most approximately one week), and the process of this whole trouble of having to repeat with time interval frequently.When using dipping or rinsing, there is same or similar problem.
For many people, use spray to have offending accident, because hearing the sound of spray, most animals (especially cat) will make fight or aggressive reactions.In addition, spray also has all shortcomings of mentioning in solid composite (especially powder).In addition, the fluid composition of using as spray more fine disperses than powder conventionally in atmosphere, and is therefore more easily applied their people and the suction of handled animal.
Also usually use the necklace or the band (for example so-called flea necklace) that with suitable parasitocidal activity agent, soak into prevent and treat multiple parasite (for example flea).This has guaranteed the good validity of short-term.Certain weakness of this processing method is especially that local application is very restricted.Conventionally, necklace or band neck and chest to kill activity very high, even may reach 100%.Yet farther body part is more difficult to process, and almost can not be affected in some cases.In addition, the activity of these necklaces limits if having time.In addition, in these necklaces, there are many attractions that do not have, and can disturb animal when wearing.
As other alternative, also can obtain and hang on conventional necklace and the disk that comprises active component.These have attractive outward appearance conventionally, but conventionally it is active and unsatisfactory, because contacting between disk and animal skin is inadequate.
Recently, found to use multiple antiparasitic active principle by local application (so-called " pouring formula " uses).Although antiparasitic active principle provides by local application, the whole outer surface that activating agent can move to watch for animals." local application " means active component to be only applied to the sub-fraction of animal outer surface, is generally line or point on animal back.
By pouring the epizoon that the local surfaces (topical) of the location of formula preparation uses to prevent and treat on sheep, cat, dog, ox and other animal (comprising goat, pig and horse), become conventional way for a long time.At the great majority known to the inventor, pour formula preparation and all existing water-insoluble IGR pour in formula preparation, activating agent is dissolved in non-aqueous solvent systems to produce the suitable formula that pours preparation.Preparation is present in these and pours solvent in formula preparation to realize in fine dispersion around of animal skin and/or the infiltration of epidermis.So far, the commercially available formula that pours preparation is suspension, missible oil (emulsificable concentrate) or solution, and usually comprises at least one organic solvent.Conventionally at these, pour the solvent that is used as carrier in formula preparation and comprise propane diols, paraffin, isoparaffin, aromatic compound (aromatic), isopropyl myristate (isopropyl myristate, IPM), glycol ether and alcohol (as normal propyl alcohol).US 4,672, and 072 discloses the preferred solvent systems that comprises 30% to 70% dimethylbenzene, 20% to 40% cyclohexanone and 5% to 25% vegetable oil.
Regrettably, when by commercially available when pouring the solvent system that is used as carrier/supporting agent in formula preparation and being applied to animal skin, it can cause the tissue reaction of some forms, this so cause animal uncomfortable, and in many cases, cause the infringement of animal skin, sheepskin or wool, thereby produce economic loss.Especially, some animal has highstrung skin, and it reacts with some commercially available solvent systems that pour in formula preparation.For example, aromatic compound (for example dimethylbenzene and paraffin) produces tissue reaction as dry in skin, rubescent and that chap.
European patent No.0137627B1 discloses a kind of formula preparation that pours, wherein active component is interior insecticide, and that carrier comprises is single-or at least one polyunsaturated fatty acid ester of the monoalky lether of poly--aklylene glycol, as acetic acid 1-ethoxy-c-2-base ester and butyric acid 2-(n-butoxy) ethyl ester.Although this specification is claimed this preparation, in the sheep of processing or ox, there is no disadvantageous skin reaction, should be noted that (especially to have in sensitive-skinned sheep) in some animals still to can be observed disadvantageous epidermis reaction.
In addition, while using the conventional formula that pours preparation, 95% to 98% the active component of using is stayed site of administration and is combined with fur or the hair of animal.This so cause lacking effect.Therefore, must use more substantial active component to animal, effectively to prevent and treat and to infect.
In addition,, when multiple known formulations is contacted with water, find that active component can be precipitated out from solvent formulation.Therefore, if be applied to wet animal, if or after using soon and animal is exposed in water (as heavy rain) processing before dry, to pour formula preparation so ineffective for solvent IGR.Multiple when pouring formula preparation and contacting with water when making, active component is precipitated out rapidly from described preparation.If said preparation is applied to wet animal, if or the processing on animal this animal is exposed in the rain before dry, active component is precipitated out from solution, and along the back deposition of this animal, solvent is also washed away by rain.This obstruction or stoped active component in the distribution around of whole animal.This phenomenon is even more important for those regions of animal downside.This phenomenon has reduced under these conditions the only validity of the preparation based on solvent.
Therefore, the current safety barrier that needs searching to be used for pouring formula preparation, it is not only to animal nonirritant, and permission end-product becomes effective, stable, water-fast preparation to mammal low toxicity.Preferably, described carrier has gratifying freezing point, suitable denseness and cost-effective advantage.In addition, preferably, described carrier can easily be prepared with active component, for example, can easily dissolve any activating agent, is easy to use and provide superior processing safety.
In the present invention, have been found that by being used as C2-C4 bis-alkylene glycol mono/bis--C1-C4 alkyl ether of solvent or carrier can reduce or overcome above-mentioned some or all shortcoming of the formula that the pours preparation of prior art in pouring formula preparation.End-product based on new support is effective, stable, the water-fast preparation to mammal low toxicity, and it is to animal nonirritant.
