Description

Technical Field [0001] The present invention relates to a gel type composition for preventing cockroach,

The present invention relates to a composition for controlling cockroaches in a gel, and more particularly, to a composition for controlling cockroaches in a gel which can be utilized as a bait or the like by maximizing an attracting effect and an insecticidal effect of a cockroach.

Cockroach is a nocturnal insecticide with high vitality and fertility. It feeds food containing starchy ingredients such as rice or bread, but it also feeds on organic matter such as paper, leather, hair, spittle, hard blood, do.

Therefore, it moves around 40 kinds of pathogenic bacteria such as viruses, salmonella, protozoa, fungi, etc. To people in the place where people live, Pneumonia, tuberculosis, cerebrospinal meningitis, and the like.

In addition, cockroaches are incomplete pest insects, and they are hatched from the algae, and soon after they come out from the larva, they are taken off the wheel and become the wheels. The crust becomes powder and stimulates the nose and bronchial joint with the house dust paper to induce asthma.

Accordingly, in recent years, a number of medicines for eliminating the cockroach have been developed and used. However, as a result of indiscriminate use of inappropriate medicines, the insects have resistance to the medicines and are hardly eradicated.

In addition, in the composition used for the cockroach extermination, the insecticidal power of the insecticide contained in the composition is insufficient, so that the cockroach ingesting the insecticide obtains resistance and thus the insecticidal effect is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a composition for controlling cockroaches which can exhibit a powerful and rapid insecticidal effect against cockroaches.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Embodiments in accordance with the concepts of the present invention can make various changes and have various forms, so that specific embodiments are illustrated in the drawings and described in detail in this specification or application. It is to be understood, however, that it is not intended to limit the embodiments according to the concepts of the present invention to the particular forms of disclosure, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise.

The composition for controlling cockroaches in gel form according to the present invention is a composition for controlling cockroaches in a gel, which comprises an insecticide preparation comprising a fipronil, an attractant and an excipient, wherein the fipronil is a composition for controlling cockroaches 0.025% to 0.10% by weight of the content .

First, the insecticidal agent necessarily contains fipronil, and the content of fipronil is preferably 0.025 wt% to 0.10 wt% of fipronil based on the total amount of the composition for controlling cockroach according to the present invention By weight, more preferably 0.05% by weight or less.

When the insecticide is used in an amount less than 0.025% by weight, the insecticidal effect of the cockroach intended by the present invention is insufficient and it is not effective in controlling the cockroach. On the other hand, when the insecticide is used in an amount exceeding 0.10% by weight, There is a possibility that the composition remaining after wasting and use becomes more likely to act as a toxic substance to other animals.

Therefore, the composition for controlling cockroaches according to the present invention has a significantly higher content of fipronil compared with the composition used for cockroach extermination in the past, and the problem of existing insecticides such as degradation of insecticidal effect due to increase in tolerance of cockroaches Can be solved.

For reference, the fipronil is a mixture of (±) -5-amino-1- (2,6-dichloro-α, α, α-trifluoro-p- tolyl) -4-trifluoromethylsulfinylpyrazole- 3-carbonitrile, represented by the following formula (1).

≪ Formula 1 >

Fipronil is effective in the disinfection of cockroaches and has been shown to be effective in the treatment of many other insect pests such as crawling insect pests, such as termites, ants, beetles, fleas, ticks, geese, thrips, root worms and weevils have.

Next, the attractant is used as a food for cockroaches to attract cockroaches, and it can be used in an amount of 10 to 55 parts by weight.

Next, the attractants are used to induce cockroaches by acting as food for cockroaches, and they may be at least one selected from the group consisting of powdered milk, fructose, white sugar and syrup. For example, whole milk powder and fructose Or a mixture of sucrose and starch in a weight ratio of 1: 3 to 1: 5 may be used.

Here, the powdered milk powder is a powder obtained by sterilizing and concentrating milk and spray drying, and generally has a pale yellow fine powder form.

The above-mentioned starch syrup refers to a mollusk starch which is obtained by hydrolyzing a starch of corn starch or pure starch (100%) raw material with an enzyme or an acid, filtering and concentrating the enzyme.

Next, the excipient is used for imparting viscosity to the composition. As the excipient, a mixture of silk powder and flour or a mixture of peanut powder and soybean oil can be used.

The mixture of the silk powder and the wheat flour and the mixture of the peanut powder and the soybean oil are characterized in that the physical properties can be widely controlled by using the viscosity. It also serves to prevent the effect of the attractant from sharply decreasing in a gel form that does not contain a volatile flavor such as unpleasant odor or strong irritation.

In addition to this, it maintains the sterilizing effect of the composition for a long period of time, and makes it easy and easy to attach to an object in an environmentally friendly and neat form.

The excipient is preferably used in an amount of 15 to 45 parts by weight because if the excipient is used in an amount of less than 15 parts by weight, the physical properties thereof become poor or they can not be prepared in a gel form. Therefore, The adhesive effect to the cockroach may be reduced. If it is used in excess of 45 parts by weight, the physical properties may become too strong, which may result in hardness or inconvenience of use because it is not well applied to the product.

Meanwhile, conventional auxiliary agents and additives may be further added to the composition for controlling cockroaches, and preferably include an agitator containing carbomer, carrageenan and soybean seed powder, a pH adjusting agent including sodium hydroxide, and glycerin A preservative comprising methyl parahydroxybenzoate, a colorant, and a solvent may be used as the coloring agent.

In another aspect, the auxiliary agent and the additive may include a binder containing polyethylene glycol, a preservative containing methyl paraoxybenzoate, and a solubilizing agent comprising isopropanol.

The composition for controlling cockroaches in the gel is preferably used in an amount of 0.5 g / m ² to 2.0 g / m ² , but is not limited thereto.

<Test Example>

(1) Test method

The compositions prepared in Examples 1, 3, 4 and Comparative Example were used as samples to test the insecticidal effect of cockroaches.

The cockroach used in the test was a German wheel (Blattella germanica), and the eggs, caterpillars and adults of the wheel were collected directly from the restaurant in Jeonju city and transferred to the laboratory.

The selected German wheels were placed in a kennel (32 × 8 × 22 cm) and reared in an insectivariate room (temperature 25 ± 2 ° C, humidity 50 ± 5%, day 12L: 12D). When the female produced the pouch, the pouch hatched from the pouch. The hatchlings migrated 5 to 7 times and became adults in 30 to 60 days. Inside the kennel, a paper box of hard material was laid. Feeds were biscuits, artificial feeds (rats feed superfeed) and water. I did not distinguish between male and female when I used it as a diploma. In this test, only the 4th generation adults raised in the laboratory were used.

The test for the insecticidal effect of insecticides against German wheels was carried out in accordance with the "Guidelines for the efficacy testing of insecticides for the prevention of infectious diseases (FDA, December 2008)". Fifty German adult cockroaches were placed in a rectangular glass container (63 cm in length, 63 cm in height, 6 cm in height), and the dock fed with the composition prepared in each of Examples 1, 3, 4 and Comparative Example 1.0 g petri dishes were placed in glass containers.

The control group (untreated group) provided only water and food under the same conditions as the test group. At the end of the experiment, the German wheel was moved to the insect feeding room, and the entrance side was leveled by putting the cotton wool into the Erlenmeyer flask containing 10% sugar water.

The insecticidal rate was examined every 24 hours for 7 days after the test, and the average insecticidal rate was calculated for each concentration. Insects which were lightly stabbed by sinking, etc., or which had no movement at all or which were almost impossible to move due to slight movement or flipping, were regarded as dead.

 All tests were repeated 5 times (50 rats × 5 rats = 250 rats per treatment group).

(2) Test results

Table 2 shows the mortality rates of German wheels obtained by treating the dock fed with the compositions prepared in Examples 1, 3, 4 and Comparative Examples.

[Table 2]

As shown in Table 2, when the compositions prepared in Examples 1, 3, and 4 and Comparative Examples were respectively prepared with bait, mortality by concentration of fipronil on the German wheel by the dock feeding method The cumulative mortality after 7 days of treatment at 0.025 wt% of fipronil was 77.6%, that of fipronil was 0.05 to 92.8%, and that of fipronil was 0.10 to 96.0%, which was higher than that of the composition prepared in the comparative example Compared with the composition prepared in the comparative example, it showed a high insecticidal effect of at least 32%.
