Description

Chicken mite acaricidal composition comprising slaked lime{Red mite acaricidal composition comprising calcium hydroxide}

The present invention relates to a chicken mite acaricide composition comprising slaked lime, and more particularly, to a chicken mite acaricide composition comprising slaked lime and ethanol and a method for controlling chicken mite using the composition.

Recently, with the introduction of an automated device for mass production, the commercialized cage system maintains the temperature and humidity inside the cage at a constant level to control the quality of the reared chicken. However, by maintaining such a constant level of environment, damage caused by parasites adapted to such environments is spread among various parasites parasitic on chickens. For example, in the case of chicken mites (Dermanyssus gallinae), such as anemia or mortality due to vampire, decreased spawning rate due to stress, contamination of eggs by mite excretion or mite mortality, as well as reduced immune response due to disturbance of the immune system. It causes damage to various spawning systems, and maintaining a constant environment can dramatically increase the growth of chicken mites. Nevertheless, since the main breeding purpose of chickens is edible, the means for controlling the chicken mites are extremely limited, and the damage caused by chicken mites is increasing day by day.

Currently, the control of chicken mite is mainly a pyrethroid (pyrethroid)-based compound, a carbamate (carbamate)-based compound, an organophosphorus-based compound, and in order to overcome disadvantages such as increased resistance by the compound, plants Although it is a situation in which a method such as a fumigation method using an oil component is used in combination, inevitably, the compound remains in the chicken, and thus secondary damage caused by the compound remaining when ingesting the chicken is concerned.

Accordingly, research has been actively conducted to develop a formulation that mainly uses natural ingredients and contains a minimum amount of synthetic compounds to develop a method that can more effectively and economically control parasites such as chicken mites. For example, Korean Patent Publication No. 10-2017-0141409 discloses a chicken mite acaricide composition comprising a mixture of nim, oil and ginkgo biloba cold water extract as an active ingredient, and Korean Registered Patent No. 10-1400713 has anise oil , A pesticide composition for chicken mites comprising a plant essential oil composed of basil oil, etc. and a compound having a phenylethyl group composed of ethyl cinnamate, isobutyl phenethyl alcohol, etc., Korean Patent No. 10-1904406 discloses a spot hole, The chicken mite control composition comprising Baek Doo-Hong, Ginkgo Berry and Pork Potato Mixed Extract, Nim Oil, Sulfur and Colloidal Silver is disclosed.

However, the chicken mite acaricide developed as described above is environmentally friendly, but has a disadvantage in that the control effect due to natural ingredients is somewhat lowered and the production cost is significantly increased as the natural ingredients are contained in a large amount, so as to find a solution to this. Needs to be.

Under these backgrounds, the present inventors tried to develop a formulation that is eco-friendly and economical and has excellent control effect against parasites such as chicken mites, and as a result, compositions containing slaked lime and ethanol that have not been used so far are excellent control for chicken mites. It confirmed that it showed an effect, and completed this invention.

The main object of the present invention is to provide a chicken mite acaricide composition comprising slaked lime and ethanol.

Another object of the present invention is to provide a method for controlling chicken mite using the chicken mite acaricide composition.

The present inventors have conducted various studies to develop an eco-friendly and economical agent with excellent control effect against parasites such as chicken mites, while focusing on the mineral material as an eco-friendly material to satisfy economic efficiency.

In general, in the case of eco-friendly preparations, components derived from plants are mainly considered, but these vegetable components are generally manufactured through extraction, concentration, and drying processes, and thus have a disadvantage that a high cost and time are required in the manufacturing process. It is not satisfying the economic feasibility.

In order to overcome the disadvantages of such eco-friendly formulations, the present inventors have confirmed that mineral ingredients can be used as eco-friendly ingredients that do not require a special processing process, and have considered the most widely used lime ingredients among these mineral ingredients. However, since quicklime (calcium oxide, CaO) shows high reactivity to water, it is difficult to use it as an active ingredient in preparations for controlling chicken mites, so slaked lime with low reactivity to water (calcium hydroxide Ca(OH)^2) It has been noted that, the slaked lime itself, as well as the lime water dissolved in water, is known to exhibit no toxicity and side effects in vivo.

As a result of treating the slaked lime aqueous solution (lime water, calcium hydroxide aqueous solution) obtained by adding the slaked lime to water, as a result of the concentration of slaked lime contained in the aqueous solution, the percentage of chicken mite was increased, but it was confirmed that complete salvation was impossible. . Accordingly, as a result of conducting various studies in order to discover supplementary components that can improve the chicken mite killing ratio, it was found that ethanol can further kill the chicken mite by further increasing the chicken mite killing ratio represented by the slaked lime aqueous solution. Could.

As such, a technique using slaked lime and ethanol for controlling chicken mites has not been developed at all, and was first developed by the present inventor.

In one embodiment for achieving the above object, the present invention provides a chicken mite acaricide composition comprising slaked lime and ethanol.

The term "calcium hydroxide" of the present invention means calcium hydroxide (Ca(OH)^2), which is a white powdery substance produced by reacting quicklime (calcium oxide, CaO) with water. The slaked lime has a low solubility in water, but dissolves in water at a low concentration to produce an aqueous solution of slaked lime (lime water) that exhibits strong alkalinity. The slaked lime has the advantage of low reactivity to water compared to quicklime, and is used in various fields, for example, it is used for bleaching powder, raw material of mortar, disinfectant, neutralization of acidic soil, and coagulation aid.

In the present invention, the slaked lime may be used in the form of a powder, or may be used in the form of an aqueous slaked lime solution (lime water), for example, it can be used in the form of an aqueous slaked lime solution that is easily mixed with ethanol.

As such, when using the slaked lime aqueous solution, the concentration of the slaked lime aqueous solution that can be used in the chicken mite acaricide composition of the present invention is not particularly limited, but as an example, 1 to 30% (w/v) of the slaked lime aqueous solution may be used, , As another example, an aqueous solution of slaked lime of 5 to 25% (w/v) may be used, and as another example, an aqueous solution of slaked lime of 10 to 20% (w/v) may be used.

In addition, the concentration of ethanol contained in the chicken mite acaricide composition of the present invention is not particularly limited, but as an example, the final volume of the composition may be 1 to 50%, and as another example, 10 to 50% As another example, it may be 30 to 50%.

The term "chicken mite (Red mite)" of the present invention, • is also referred to as a mite, a kind of parasite that parasitizes and vampires in birds, and refers to an ectoparasite belonging to the mite family of the mite, mid-sized, subfamily. Chicken mites parasitic on chickens and vampires are mainly found at night, and during the daytime, they are hidden in shaded areas or crevices, making them difficult to detect, and when noticed, they often occur in large quantities. After hatching, the young mite is about 0.5mm long and has 3 legs. The adult mite is 4 mm long and has 4 legs. Adult mites show a black-red appearance due to blood, sometimes exceeding 1 mm in the aspiration stage immediately after blood-sucking. Although the amount of blood per head is very small, chickens may die of anemia in large farms.

The chicken mite becomes the larval mite after hatching from the egg and becomes the first young mite without a vampire process. The first young mite becomes the second young mite within 24 hours after the vampire, and then becomes more vampire and becomes a mature mite. It is known that the eggs become mature mites in about 9 days and repeat vampire and spawning.

In one embodiment of the present invention, as a result of measuring the acaricidal effect of chicken mite exhibited by 10% and 20% slaked lime aqueous solution, 10% and 20% slaked lime aqueous solution showed the acaricidal effect for chicken mites of 72.0& and 92.3%, respectively. It was confirmed (Table 1), 10% and 20% of ethanol 30%, 40% and 50% of ethanol in an aqueous solution to obtain the respective formulations, as a result of measuring the acaricidal effect of these formulations, all formulations of 100% It was confirmed that the acaricidal effect on chicken mites was shown (FIG. 1).

Therefore, it was found that the preparation containing slaked lime and ethanol showed effective acaricidal activity against chicken mites.

In another embodiment, the present invention provides a method for controlling chicken mite comprising treating the chicken mite acaricide composition.

Specifically, the method for controlling the chicken mite includes spraying the chicken mite acaricide composition on the bio-appearance of a chicken that is or is likely to be infected with the chicken mite.

The term "control" of the present invention, as a series of actions to reduce the damage caused by pests, can be distinguished from "pesticides" that necessarily involve killing and eliminating pests. Therefore, using the chicken mite acaricide composition of the present invention may have little or no effect to disturb the ecosystem. In addition, since the "control" may include "repelling", the chicken mite acaricide composition of the present invention can also be used as a composition for avoiding chicken mites.

When using the chicken mite acaricide composition provided in the present invention, it is possible to effectively control the chicken mite while using economical and eco-friendly materials, which will greatly contribute to the increase in income of the farm house.

Hereinafter, the present invention will be described in more detail through examples. However, these examples are for illustrative purposes only, and the scope of the present invention is not limited to these examples.

Example 1: Control effect of chicken mite in slaked lime

First, 1 g of slaked lime powder was dissolved in 9 ml of distilled water to prepare a 10% slaked lime aqueous solution, and 2 g of slaked lime powder was dissolved in 8 ml of distilled water to prepare a 20% slaked lime aqueous solution.

Next, 600 µl of each prepared slaked lime aqueous solution was dispensed into a 50×15 mm insect breeding dish.

20 chicken mites were dispensed into each insect breeding dish in which each aqueous solution of slaked lime was dispensed, and an experiment for measuring the percentage of chicken mites after 24 hours was repeated 3 times (Table 1). In this case, an insect breeding dish that was not dispensed with a solution of slaked lime was used as a control.

As shown in Table 1, it was confirmed that the 10% slaked lime aqueous solution showed an average killing rate of 74% for chicken mites, and the 20% slaked lime aqueous solution showed an average killing rate of 92.3% for chicken mites.

Therefore, it was found that the percentage of chicken mite was increased depending on the concentration of slaked lime contained in the aqueous slaked lime solution.

Example 2: Chicken mite control effect of a formulation containing an aqueous solution of slaked lime and ethanol

As shown in Example 1, depending on the concentration of slaked lime contained in the slaked lime aqueous solution, the percentage of chicken mite was increased, but since it was impossible to completely control the chicken mite, it was possible to assist the chicken mite killing effect of the slaked lime aqueous solution. Ethanol was excavated as a component, and the control effect of chicken mite control of a formulation containing a solution of slaked lime and ethanol was compared.

Roughly, each chicken mite acaricide composition was prepared by variously combining slaked lime powder, distilled water and 100% ethanol (Table 2).

Next, using the method of Example 1, except for using each of the chicken mite acaricide composition prepared in Table 2 instead of the aqueous solution of slaked lime, the meat for chicken mite represented by each of the chicken mite acaricide compositions Ratios were compared (Figure 1). In this case, an insect breeding dish that was not dispensed with an aqueous solution of slaked lime was used as a positive control, and an insect breeding dish with only 10% or 20% aqueous solution of a slaked lime was used as a negative control.

1 is a graph showing the results of comparing the chicken mite kill ratio of the chicken mite acaricide composition of various compositions provided by the present invention.

As shown in FIG. 1, when only the aqueous solution of slaked lime was used, some chicken mites survived, but when the composition containing the aqueous solution of slaked lime and ethanol was used, it was confirmed that chicken mites were all killed regardless of the concentration of the aqueous solution of slaked lime and the concentration of ethanol. .
