Description

  The present invention relates to a flying insect control agent and a flying insect control method using the same.

Conventionally, a method of applying a repellent containing diet (N, N-diethyl-toluamide) to the skin surface against flying pests such as mosquitoes, moths, chironomids and flies has been widely used. Since the volatility is somewhat lower than that of the fragrance component, a spatial repellent effect cannot be expected.
Therefore, there are some proposals to use volatile natural essential oils and their components as repellent components. For example, it is well known that citronella oil and its main component citronellal have a repellent effect on mosquitoes, and candles containing citronella oil as an active ingredient are commercially available in the United States. However, the method of dissipating citronellal using the heat of the candle has poor volatilization efficiency of citronellal and cannot provide a practical repellent effect.
Japanese Patent Application Laid-Open No. 2002-173407 (Patent Document 1) describes a flying pest repellent containing, as an active ingredient, a natural essential oil selected from orange oil, cassia oil and the like in addition to citronella oil. Kai 2003-201303 (Patent Document 2) includes, as pest repellent component (A), citronellal and one or more selected from terpineol, menthol, limonene, geraniol, citronellol, camphene and the like, A pest repellent volatilization composition in which the content of citronellal in the pest repellent component (A) is 2 to 10% by mass is disclosed. Although these repellents urge the attention to natural products and safety, their repellent effects are not always satisfactory.

On the other hand, a method of controlling flying insects by volatilizing an insecticidal component exhibiting insecticidal efficacy at room temperature naturally or by a wind power such as a fan has been conventionally performed. For example, JP 2005-314439 A (Patent Document) 3) discloses metfurthrin and profluthrin as useful room temperature volatile pyrethroid insecticides.
In addition, for example, Patent Document 1 discloses that the insecticide component and the repellent component are used in combination, "By using a natural essential oil and a pyrethroid insecticide together, the repellent effect against flying insects can be further enhanced." Is described. However, the insecticidal components exemplified in the examples are only pinamine forte and etoc that do not have room temperature volatility and require heating, and do not provide an efficient flying pest control system. Absent.

Demonstrate.
The flying insect pest control agent may be composed only of the insecticidal component and the flying insect repellent component, but it is practical to use it in a holding body together with various components, and a container containing such a holding body. Is preferably used in a small space, for example, a space of about 10L to 500L. In addition, when each active ingredient is contained in the same holding body, one component may suppress the volatility of the other, so that the form to be contained in separate holding bodies matches the purpose of the present invention.

Examples of the support include solid, sheet, and gel. Among them, cellulose-based carriers such as paper, pulp, linter, and viscose, ethylene-vinyl acetate resin (EVA), polyester, olefin polymer, and the like.

In the present invention, the content of the insecticidal component and the flying insect repellent component per flying insect pest control agent varies depending on the form of the holding body. For example, in the case of a solid or sheet, the insecticidal component is 10 to 200 mg and the flying insect repellent. The component is preferably set to about 50 mg to 2 g. According to such a dose, it is possible to exert an excellent control effect against flying pests over a period of 1 to 2 months in a space up to about 500 L.

The flying pest control agent of the present invention further includes at least one selected from the group of Gramineae, Camellia, Ginkgo, Moleaceae, Mulberry, Citrus, Kintranoaceae, and Oysteraceae as components for enhancing the flying insect repellent efficacy. It preferably contains a plant extract.
Such plant extracts, such as polyphenols, are known as deodorizing components, but the knowledge that they act as efficacy enhancing components for flying insect repellent components used in the present invention is completely new. Although the details are unknown, it is presumed that some interaction is exerted when the repellent component evaporates.

And nonionic surfactants such as higher alkylamine oxide surfactants such as laurylamine oxide, stearylamine oxide, and laurylamidopropyldimethylamine oxide.

As for the flying insect pest control agent of the present invention, it is practical to use the holding body containing the above-mentioned various components in a plastic container having an opening. You may make it attach a double-sided adhesive tape to the back surface of a container, and fix to the wall etc. of an application space.
The flying pest control agent of the present invention obtained in this way is a relatively small space such as a living room, a Japanese-style room, a front door, a warehouse, preferably a trash can, a garbage collection box, etc. 1 to 2 months depending on the interaction of insecticidal components and flying insect repellent components against flying insects such as moths, chironomids, flies, fruit flies (Drosophila, fleas, etc.), butterflies and moths It has a practical control effect over a long period of time. In particular, when it is applied to fly fly control in a trash can, a waste collection box or the like, it can repel fly fly, but it can also kill insect fly close to the waste or generated from the waste, thereby enabling complete and efficient control. This association of repellent action and insecticidal action is not only complementary but extremely synergistic, and the control method of the present invention using such a flying pest control agent provides a remarkable control effect that can hardly be predicted from conventional knowledge. To do.

Next, based on a specific Example, the flying insect control agent of this invention is demonstrated in detail.

A pulp base paper (A) having a size of 60 mm × 60 mm and a thickness of 1.0 mm was made to contain 150 mg of kerosene solution containing 40 mg of profluthrin as a room temperature volatile insecticidal component. On the other hand, 800 mg of flying insect repellents containing terpineol, citronellyl acetate, citral, nonyl alcohol, and eucalyptus oil as the main components on a pulp base paper (B) having a size of 25 mm × 47 mm and a thickness of 2.8 mm. 100 mg of ginkgo biloba extract was contained as a pest repellent efficacy enhancing component. Pulp base papers (A) and (B) were stored side by side in a polyester container (opening: 27 cm ² , with double-sided adhesive tape on the back) to obtain the flying insect control agent of the present invention.
The flying insect pest control agent was fixed to the back of the lid of a 50 L garbage storage container with double-sided adhesive tape, and the garbage storage container was placed on a veranda and used as usual. Over two months, no fly fly and other flying pests were found in the garbage storage container as well as around the lid, and an excellent control effect was confirmed.

According to Example 1, various flying insect control agents shown in Table 1 were prepared, and the following control efficacy test was conducted.
[Control efficacy test]
Two semi-sealed plastic cases (about 30 L) provided with small holes on the upper surface through which Drosophila can pass are provided in the test chamber (about 6 m ³ ). In one plastic case, the flying pest control agent and the Drosophila attracting source shown in Table 1 were placed (treatment section), and only the Drosophila attracting source was placed in the other plastic case (control section). About 100 Drosophila adults were released indoors, and after 2 hours, the number of invading insects in the plastic cases was counted, and the control rate was calculated according to the following formula.
Control rate = [(number of invasive insects in control group−number of invasive insects in treatment group) / number of invasive insects in control group] × 100

As a result of the test, the flying pest control agent of the present invention containing an insecticidal component exhibiting insecticidal efficacy at room temperature and a flying pest repellent component as an active component is synergistic compared to Comparative Examples 1 to 3 containing only any active component. The control effect was further enhanced by adding a plant extract as a component for enhancing the flying insect repellent efficacy.
As the flying insect repellent component, as can be understood with reference to the present invention 9 to 13, jasmine oil, neroli oil, peppermint oil, bergamot oil, orange oil, geranium oil, petitgren oil, lemon oil, citronella oil, lemon Essential oils consisting of glass oil, cinnamon oil, eucalyptus oil, thyme oil, and its constituent components citral, l-menthol, citronellyl acetate, cinnamic aldehyde, terpineol, nonyl alcohol, cis-jasmon, thymol, limonene, linalool, Two or more kinds selected from 1,8-cineole, geraniol and α-pinene were preferred.
Moreover, from the comparison with the present inventions 1 and 14, it is more effective to contain the insecticidal component and the flying insect repellent component in separate holders, but as in Comparative Example 4, the volatility is poor as the insecticidal component. It has also been clarified that the use of phenothrin affects the volatility of the flying insect repellent component and causes a reduction in the control effect.

According to Example 1, various flying pest control agents shown in Table 2 were prepared, and the following reproduction inhibition efficacy test was conducted.
[Reproduction suppression test]
Two semi-enclosed boxes (about 200 L) with small holes on the upper surface through which Drosophila can pass are provided in the room (about 41 m ³ ) where adult Drosophila were released. In one semi-enclosed box, the flying insect control agent listed in Table 2 [containing the drug holder in a polyester container (opening: 30 cm ² )] and the Drosophila egg-laying medium (treatment area), Only the Drosophila egg-laying reproduction medium was placed in the semi-sealed box (control group). After 5 days, the egg-laying propagation media in both sections were collected, and the breeding larvae were counted, and the reproduction inhibition rate was calculated according to the following formula.
Reproduction suppression rate = [(number of breeding larvae in control group−number of breeding larvae in treatment group) / number of breeding larvae in control group] × 100

As a result of the test, the flying pest control agent of the present invention containing an insecticidal component exhibiting insecticidal efficacy at room temperature and a flying pest repellent component as an active component is synergistic compared to Comparative Examples 1 to 3 containing only any active component. The reproductive inhibition effect was further enhanced by adding a plant extract as a component for enhancing the flying insect repellent efficacy.
It is very important to suppress the occurrence of flies from the beginning together with prevention of invasion, and the flying pest control agent of the present invention, which is excellent in both effects, can provide an extremely efficient method for controlling flying pests. is there.

The flying pest control agent and the flying pest control method using the same of the present invention can be used not only for flying pests but also for the purpose of controlling a wide range of pests.
