Description

Cockroaches and Ants Insecticides {THE INSECTICIDAL METHOD FOR COCKROACHES AND ANTS}

1 is an experimental apparatus for testing the repellency of plant essential oils.

Figure 2 is a graph showing the evasion force of the German wheel for 20 kinds of plant essential oils.

3 is a graph showing the avoidance of the antler ants for four citrus spp.

The present invention relates to a method of insecticide of cockroaches and ants.

Cockroaches are pests that cause allergic diseases such as bronchial asthma, rhinitis, atopic dermatitis, and microscopic particles such as excreta and molting components of roaches come into contact with the skin, bronchial or nasal mucosa of a person who is allergic to cause disease.

Indirect damages are mediated by many pathogens such as bacteria, viruses, and various parasites to cause infectious diseases, but above all, it is a representative hygiene pest that gives severe aversion to humans.

Cockroaches live in the colony using aggregated pheromones, and if one is found in a living space as a nocturnal pest, it can be said that 50 to 100 cockroaches are hidden in the invisible place.

These cockroaches are the most common habitats in areas near the moist, food-rich kitchens. The cockroaches that feed have a habit of distributing vomiting food to other wheels.

At this time, when it is excreted with the stool through the digestive tract propagates the pathogen.

In other words, cockroaches were not common in homes only 30 years ago, but their lifestyles have changed, and especially during winter heating, they have become a sanitary pest mainly living in hotels, inns, restaurants, apartments, etc. .

The most common cockroach in Korea is the German wheel ( Blattella). germanica ) widely distributed throughout the country, and other wheels periplanata fuliginosa ), Japanese wheels ( Blatta orientalis ), and the Periplanata americana ), etc.

Ants are social insects ants as a major problem in our country is hygiene pests pharaoh ant (Monomorium pharaonis ), Bear ant ( Formica japonica ), Japanese Royal ant ( Camponotus) Japonicus ), Fire Ant ( Formica) Yessensis ), and the ants that appear in residential spaces generally work as ants and use chemical pheromones and trail pheromones to chemically communicate between species.

These ants are omnivorous and find food waste or debris in their homes and invade through building cracks. They also mediate pathogens by contaminating food through contact with food that is not eaten by humans.

In particular, the bite of people and pets can cause pain. Ant poisons can cause serious rashes or allergies in sensitive or fragile baby skin.

In order to control cockroaches and ants, which are sanitary insects in residential spaces, aerosol insecticides, installed poisons, fumigant smokers, chalk contact insecticides, etc. are currently used.

However, aerosol insecticides only kill visible pests, and fuming smokes have the effect of killing pests in certain spaces at once, but invisible areas or cockroaches in crevices are difficult to kill, and deep in spaces sprayed through gaps or holes. Ants traveling from place to place through the guiding pheromone are more difficult to eradicate.

Chalk-type contact insecticides only prevent cockroaches or ants entering the space by drawing lines, and because of the nature of the formulation, they are not clean and likely to be touched by young babies.

Therefore, the most commonly used formulations for controlling cockroaches and ants are rodent poisons, and as insecticides, hydramethylnon, an amidinohydrazone insecticide, and organic phosphorus are commonly used. Chlorpyrifos, an organophosphate insecticide, propoxur, a carbamate insecticide, fipronil, a phenylpyrazole insecticide, and boric acid. These studies have been used, and various studies such as the following have been conducted.

Korean Laid-Open Patent Publication No. 2001-0089952 (cockroach insecticide composition), characterized in that the cockroach insecticide composition comprises 1-3 weight per weight total composition of hydramcinolone and propofsol in the ratio of 1: 1.5 to 1.5: 1. Increasing pesticidal and rapid pesticidal compositions are disclosed.

Korean Patent Publication No. 10-0461086 (composition of insecticide microcapsules for degradable cockroach attractant poisoning agent for hydrogen ion concentration), cockroach attractant poisoning agent is encapsulated with hydrophobic core material and wall material of microcapsules in the digestive organ of cockroach It is disclosed that a composition exhibiting an effect of expressing a chain insecticidal effect upon re-ingestion of vomiting foods by prolonging the toxic expression period by causing degradation according to environmental changes in hydrogen ion concentration.

Korean Patent Publication No. 10-0478139 (Insecticidal composition against mosquitoes, ants, ticks, cockroaches and stock pests), pesticide composition showing the insecticidal effect against mosquitoes, ants, ticks, cockroaches using various plant oils Is open to the public.

Korean Patent Publication No. 10-0308582 (Insecticide composition for cockroaches and ants and a method for preparing the insecticide) discloses a pesticide using boric acid as a pesticide component and potato and lacquer components.

However, poisonous insecticides prepared from the above pesticidal components contain most of the attractant components, and the insecticidal effect depends on the use of the attractant component having a high attraction force.

In particular, these insecticides are divided into fast-acting and slow-acting insecticides. In the case of fast-acting insecticides, cockroaches and ants have a fast insecticidal effect when ingested poisonous insects, but they have a disadvantage in that the feeding rate is lowered by sending a signal to the same species. In the case of ant, a social insect, the effect is negligible when a poison is made using a fast-acting insecticide.

In addition, even when a poisonous insecticide and an attractant are mixed to make a poison, there is a disadvantage in that the attractant of the attractant is exerted when a large number of poisons are processed in a specific space. There is a problem that touches the hands of young children with aesthetically unfavorable point.

In order to solve the above problems, an object of the present invention is to provide a pesticidal method exhibiting high insecticidal properties against cockroaches and ants by using a attractant poisoning agent and aroma repellent.

In other words, excellent insecticides are simultaneously used by attracting poisonous agents that exhibit slow insecticidal action by using slow-acting insecticides that inhibit the action of the electron transfer system and aromatic repellents that have the function of disturbing the signaling material possessed by insects due to the repellent ingredient that insects do not like. The aim is to provide pesticides that work.

In addition, there is a purpose to provide a pesticidal method to increase the user's preference to use aesthetically and at the same time aesthetics.

The present invention relates to a method of insecticide of cockroaches and ants.

Insecticidal method of the cockroach and ant of the present invention, the first process for preparing a attractant poisoning agent by mixing the slow-release insecticide component, excipients, attractant flavor, grapefruit oil (lemon oil), lemon oil (lemon oil), lime oil the second step of preparing aroma repellent by selecting one or four types of lime oil and orange oil, one or two selected from insect cockroaches or ants, And a third step of disposing the attractant poisoning agent prepared in the first step, and placing the aromatic repellent agent prepared in the second step on the other side and simultaneously treating the same.

Attractant poison used in the present invention is a substance that attracts the wheels or ants to feed the insects, it means that the insects are contained in the food is naturally insecticides due to the intake of the wheels or ants.

These insecticides are divided into fast-acting and slow-acting insecticides. In the case of fast-acting insecticides, cockroaches and ants have a fast insecticidal effect when ingested poisons. In the case of ants that are insects, there is a problem that the effect is very insignificant when a poison is made using fast-acting insecticide.

But. Even if the poisonous insecticide and the attractant are mixed to make the poison, there is a disadvantage that the attraction of the attractant is exerted when a large number of poisons are processed in a specific space. Thus, the installed poison is treated at appropriate intervals in the residential space. There is also a problem with the touch of a child, with a poor taste.

Therefore, the inventors of the present invention to solve the above problems, to find a pesticidal method with a high insecticidal effect, a number of studies, as a result of mixing the slow-acting pesticides, excipients, attractant fragrance to prepare a attractant poisoning agent, aroma As a repellent, one to four of grapefruit oil, lemon oil, lime oil, and orange oil are selected. It is to find a pesticide method to increase the user's preference to use aesthetically and at the same time, while showing a high pesticidal effect on the wheels or ants when disposed at the same time and placed aroma repellent on the other side.

Here, the aroma repellent agent exhibits the action of the repellent component disliked by pests, and at the same time, it is a substance that disturbs the signaling material possessed by the insect, and thus shows a higher insecticidal effect on wheels and ants.

Hereinafter, described in detail the insecticidal method of cockroaches and ants of the present invention.

How to kill insects and cockroaches

1. Step 1: Manufacture of attractant poison

Attractable pesticides, excipients, and attracted flavors are mixed to prepare attractant poisoning agents.

At this time, the sustained insecticidal ingredients are 1 to 5% by weight based on the total weight of the attractant poisoning agent, excipients are 90 to 97% by weight relative to the total weight of the attractant poisoning agent, and attractant is attracted by mixing 1 to 4% by weight relative to the total weight of the attractant poisoning agent. It is desirable to prepare poisons.

Sustained-release insecticides include chlorfenapyr, fenpyroximate, pyridaben, pyridaben, rotenone, tebufenpyrad, hydramethylnon and lufenuron Use one of the selected.

Excipients are added to make the food easier to eat or to form a certain form, the foods consumed by cockroaches and ants such as starch syrup, corn flour, barley flour can be used.

2. 2nd Step: Selection of aroma repellent

As the fragrance repellent, one to four of grapefruit oil, lemon oil, lime oil and orange oil are selected.

At this time, when selecting two paper forms as an aromatic repellent, it is preferable to mix and use in the same ratio.

In addition, the formulation of the fragrance repellent is prepared and used in the gel or electric fragrance type.

In the gel form, 120 g of purified water is added per 4 g of beads made of Carboxymethyl cellulose, and the beads absorb all of the purified water, and grapefruit oil is added to the kerosene-based solvent. After treating 1 to 4 selected from grapefruit oil, lemon oil, lime oil and orange oil with 10% by weight of the solvent, the solvent in which the plant essential oil is dissolved is treated. The gel-flavored repellent is prepared by mixing in the vessel containing the beads prepared previously.

At this time, the use range of the plant essential oil is 0.5 to 80.0% by weight, 0.5% by weight or less is not effective, and 80.0% by weight or more because it is difficult to formulate a gel.

In the manufacture of an electric fragrance type, a general electric fragrance fragrance is used, wherein the contents of the liquid bottle are likewise selected from grapefruit, lemon, lime and orange. Species to four species are treated with kerosene-based solvents 10% by weight relative to the solvent to prepare an electric fragrance-type aroma repellent.

At this time, in order to control the rate of volatilization of oil having a repelling effect, it is possible to adjust the temperature of the fragrance or to select a solvent having a different initial boiling point, and to change the mixing ratio. Do.

The content of plant essential oils can be 0.5 to 100% by weight, less than 0.5% by weight has no repelling effect, 100% by weight can be volatilized using an electric fragrance with only plant essential oils without other components.

3. Step 3: How to kill cockroaches and ants

One or two species of cockroaches or ants to be killed are placed on one side of the room, and the attractant poisoning agent prepared in the first step is placed on one side of the room, and the aroma repellent prepared in the second step is placed on the other side and treated simultaneously. And pesticides ants.

Hereinafter, the method for killing cockroaches and ants of the present invention will be described in detail with reference to Examples and Experimental Examples.

The cockroach used in this experiment was the most common German wheel ( Blattella) in domestic households. germanica) were used for adult cancers may, as a general pharaoh ant ants in the country (Monomorium ants of pharaonis ) were used.

2. Experimental method

10 μl of each of the plant essential oils shown in Table 1 was pipetted onto the filter paper (peppeted) to select which of the treated side (Treated side) and the untreated side (Untreated side) to select and move 40 times. It was.

At this time, in order to measure the repellent force for the plant essential oil of cockroaches or ants, T-tube olfactometer (olfactometer) was used.

The t-tube olfactometer measures 9 cm in diameter, the length of the T-type arms is 22 centimeters, and the length of the stem is 10 cm, and the angle of both arms and arms is 180 ° between the columns. (FIG. 1).

In addition, the air was moved at a rate of 100 ml / min using an air pump to prevent oil components from saturating in the plant essential oil and circulate to the stem, and the injected air was silica gel and activated carbon. The layer was passed through and purified.

For the cockroach, the cockroach was run for 5 minutes in the dark and the Pharaoh ant for 10 minutes in the fluorescent light.

3. Experimental Results

1) Evaluation of German Wheels

As a result of the experiment, the repellent effect of the cockroach on 20 kinds of plant essential oils as shown in FIG.

That is, grapefruit oil, lemon oil, lime oil, orange oil, clove leaf oil, respectively, from the 20 plant essential oils. In order of 96.7%, 92.9%, 86.7%, 71.4%, and 70.0%, the avoidance effect on German wheels was shown.

In particular, all of the four plant essential oils except Clove Leaf were citrus ( Citrus). spp .) is an essential oil of the genus Citrus In spp .) , Pettigrain had a low repelling effect.

Therefore, its cause and each citrus species ( Citrus spp .) Gas chromatography (GC) and mass spectrometer (MS) analysis to identify the main components of plant essential oils of the genus, as shown in Table 2 below grapefruit oil, lemon oil, lime oil, orange oil The main component of limonene was limonene, and the content of limonene was only 2.50% for pettigrain.

<Table 2> Citrus species (Citrus spp .) Main components of the genus Plant Essential Oil

Citrus oil α- pinene β-pinene β-myrcene limonene γ-terpinene benzene linalol linalyl acetate grapefruit oil 0.69 0.27 2.32 92.35 0.19 0.22 - - lemon oil 2.11 13.52 1.41 61.30 4.23 8.47 - - lime oil 2.40 11.66 1.11 47.68 3.40 18.29 - - orange oil 0.75 - 2.53 93.79 - - - - pettigrain oil 0.20 2.50 - 2.50 2.00 - 23.00 50.00

In other words, the plant essential oils that can be used as an ingredient of the fragrance repellent for wheels were grapefruit oil, lemon oil, lime oil, orange oil. .

2) Evaluation of Love Ants

Citrus species such as the German cockroach (Citrus spp .) was tested using the T-tube olfactometer method to determine whether the repellent effect on the four plant essential oils in the antler ant, as shown in FIG. The same ant was found to have a repelling effect.

Experimental Example 2 Experiment in Mini-field

1. Experimental Materials

The attractant poisoning agents and gel-type aroma repellents of Examples 1 and 2 were prepared.

The attractant poisoning agents of Comparative Example 1 and Comparative Example 2 were prepared, and the attracting agent of Comparative Examples 3 and 4 and the gel-type aroma repellent were prepared.

2. Experimental method

Prepare a 20 cm (length) × 100 cm (width) × 30 cm (height) pictograph for mini-field experiments, and then cover the top with a 5 cm width to prevent the testworm (cockroach or ant) from escaping. I went to petroleum jelly to prepare.

The attractant poisoning agent and gel type anti-repellent agent of Example 1 and Example 2 prepared inside each experiment, the attractant poisoning agent of Comparative Example 1 and Comparative Example 2, the attractant poisoning agent of the comparative example 3 and Comparative Example 4 I put them each.

Test insects were used as 1-year-old nymphs for the German wheel, and worker ants for the antler ants, and 1, 2, 4, 8, 16, 30, and 60 after 50 animals were treated. Pesticides were evaluated over time.

3. Experimental Results

As a result of the experiment, shown in Table 3 below.

Table 3 Insecticidal Test

process Pesticide pests after treatment 1 day 2 days 4 days 8 days 16 days 30 days 60 days German Wheel Example 1 6 14 21 42 50 50 50 Example 2 3 12 24 38 50 50 50 Comparative Example 1 0 One 3 4 14 43 47 Comparative Example 2 0 2 4 11 19 27 32 Comparative Example 3 2 6 14 21 37 47 50 Comparative Example 4 One 3 9 15 30 48 50 Love Ant Example 1 One 3 7 16 32 47 50 Example 2 One 3 4 12 29 37 48 Comparative Example 1 0 One One 3 7 11 19 Comparative Example 2 0 0 2 9 19 26 32 Comparative Example 3 One One 4 11 17 26 33 Comparative Example 4 One 2 4 9 14 23 37

As shown in Table 3, the German wheel is confirmed that the insecticidal effect of 100% on the 16 days of treatment in Example 1 and Example 2 treated with a gel-type aroma repellent with the attractant poisoning agent containing the sustained-release insecticide component of the present invention However, Comparative Example 2, which was treated with an attractant poisoning agent containing a sustained-release insecticide alone, exhibited low insecticidal activity even at an initial stage, and was only 54% insecticidal even after 30 days of treatment.

In Comparative Example 1, in which the attractant poisoning agent containing the fast-acting insecticide alone was treated, the insecticide rate of 94% was shown after 60 days.

Therefore, the present experiment confirmed that the insecticidal effect including the sustained insecticide and the repellent fragrance appeared faster in the insecticidal effect of the German wheel, especially in the treatment of hydramcinolone attractant poisoning agent. It was found that the effect was higher when treated with repellent fragrance.

Compared to cockroaches, the antler showed lower insecticidal rate and insecticidal activity, which is a social insect.

In addition, the insecticidal effect of the antler ant showed a higher insecticidal effect than that of Comparative Example 1, in which only the attractant poisoning agent containing the sustained insecticidal ingredient was treated, which had a hydramethanone component compared to the fast-acting insecticide. I could confirm that I received less.

In Example 1, in which the attractant poisoning agent and the aromatic repellent containing the slow-release insecticidal ingredient of the present invention were simultaneously treated, 94% of insecticidal activity after 30 days and 100% of insecticidal activity after 60 days were shown.

This suggests that odor pheromone and trail pheromone in the forage activity of the antler are more than simple repellents in the insecticidal use of attractant toxins containing susceptible insecticides. It can be seen that it represents an additional function that disturbs the action of).

This is because such a pheromone component is a component of terpenes, and the component which acts as a repellent is similarly a terpene.

This phenomenon appears to be similar in the case of cockroaches.

Lufennuron, which was used as a sustained insecticide with hydramethanone, had higher insecticidal properties than cockroaches using the first insect larvae, but the ant insecticidal activity was slightly lower than that of hydramethinone. .

Experimental Example 3 Field Experiment

1. Experimental Materials

The attractant poisoning agent of Example 3 and the electric fragrance-type aroma repellent were prepared.

The attractant poisoning agents of Comparative Example 1 and Comparative Example 2, the attractant poisoning agent of Comparative Example 5 and the electric fragrance fragrance repellent were prepared.

2. Experimental method

In order to evaluate the insecticidal properties of cockroaches and ants living in actual residential space, the following procedure was conducted.

The attractant poisoning agent and electric fragrance fragrance repellent of Example 3 prepared above, focusing on the consumer home where cockroaches and ants are generated, the attractant poisoning agent of Comparative Example 1 and Comparative Example 2, and the attractant poisoning agent and electric fragrance type of Comparative Example 5 Aroma repellents were each distributed.

At this time, 10 families were selected for cockroaches and 10 families for ants, and insecticidal effects were conducted in field conditions for 90 days as follows.

Use satisfaction was surveyed based on the following criteria.

* Customer Satisfaction Standard

3. Experimental Results

As a result, it is shown in Table 4 below.

<Table 4> Insecticidal Survey and Satisfaction Survey

process Number of households with pests after product disposal satisfaction 10 days 30 days 60 days 90 days incense product cockroach Example 3 3 One 0 0 4.8 4.8 Comparative Example 1 9 5 7 13 - 2.2 Comparative Example 2 18 5 3 4 - 3.2 Comparative Example 5 4 3 2 5 4.2 3.8 ant Example 3 2 2 One 0 4.8 5.0 Comparative Example 1 14 11 15 16 - 1.6 Comparative Example 2 15 8 2 2 - 3.4 Comparative Example 5 3 2 4 4 4.4 3.6

As shown in Table 4, as a result of evaluating long-term insecticidal and use satisfaction of 90 days for the assumption that the problem is due to cockroaches and ants, it can be seen that the high insecticidal effect when the present Example 3 is treated there was.

In addition to the repellent effect on cockroaches and ants, the electric fragrance-type fragrance repellent has a high effect as a fragrance that enhances the user's satisfaction because the main components such as limonene emit a fresh fragrance.

In addition, since the repellent component diffuses into a wider space than the gel type repellent, the electric fragrance-type aroma repellent was found to have characteristics that can further increase the repellency efficiency with the gel type repellent when applied to a large space of a general household.

In consumer evaluation, it was found that it prevents the emergence of cockroaches and ants from the living space, and enhances the insecticidal effect by disturbing and dissipating the semi-chemical pesticides between pests in the opposite direction where the poison is installed.

The present invention provides a pesticidal method that exhibits high insecticidal properties against cockroaches and ants by using a attractant poison and an aroma repellent.

In addition, it provides a powerful insecticidal effect and at the same time provides a pesticidal method that enhances the user's use preference.
