DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pesticide for insects such as cockroaches, ants, termites, flies, mosquitoes, flies, mites, and fleas.

[0002]

2. Description of the Related Art Insect juvenile hormone (hereinafter abbreviated as JH) has a function of controlling insect metamorphosis together with molting hormone. Insects are most sensitive to JH during the last instar larva stage, when larvae are transformed from larvae to pupae or from larvae to adults, and when excessive JH is given during this period, emergence disorders such as pupal death and abnormal metamorphosis occur. Cause death. Therefore, a synthetic compound having the same action as JH (hereinafter referred to as JHM)
(Just abbreviated as "."), And some JHMs are currently in practical use. On the other hand, as a group of compounds included in the category of insect growth regulators along with JHM, there is a chitin formation inhibitor.
Chitin formation inhibitors are characterized by their ability to inhibit the synthesis of new cuticles during the molting of insects, resulting in death.
It has a completely different action from HM. Both have completely new properties different from conventional insecticides,
In addition, since they are relatively safe for mammals and exert their specific effects on insects, they are often referred to as representatives of insect growth regulators.

[0003] is a larvicidal effect by inhibiting molting and metamorphosis as main effects mentioned earlier against pests of both the insect growth regulator, fertility effect of reducing the adult fertile In addition Is also known to have

[0004] However, the method of treating these insect growth regulators currently used is exactly the same as the conventional method of treating insecticides (for example, in the case of fly control, application to the surface of livestock dung,
In the control of cockroaches and fleas, the use of aerosols and smokers and the spraying of residual liquids, etc.). It could not be expected. The reason for this is that it was necessary to incorporate a large amount of drug into the pest in order to have a sterile effect on adult pests by a conventional insect growth regulator, and furthermore, a conventional treatment method resulted in a sterile effect It was not possible to incorporate the necessary amount of drug into the pest. Also, M
asner et al. As reported in (1968), the infertility effect of insect growth control is higher for females, but lower for males. Could not be expected to have any effect on adult males.

[0005]

As described above, in the above-mentioned prior art, the adult pests are effectively sterilized, and furthermore, an effect is exerted not only on female adults but also on male adults, and mating with this is achieved. There was no agent that could bring female adults to infertility, and there was a problem to be a pest control agent that could take up insect juvenile hormone in an amount sufficient for sterilization of adults. .

[0006]

In order to solve the above problems, the present invention provides 2- [1-methyl-2- (4
-Phenoxyphenoxy) ethoxy] pyridine as an active ingredient, a predetermined adhesive was added to the pesticide to impart adhesion to the body surface of the pest.

[0007] The above pesticide comprises 0.1 to 5% by weight of an insect juvenile hormone-like compound, 0.1 to 20% by weight of an adhesive, and 0 to 5% of sugar.
20% by weight, 0-20% by weight of protein, 0 pheromone
Either 0.1% by weight and the remaining component as water to obtain a liquid composition, or a gelling agent by adding 0.5 to 10% by weight of a gelling agent, or a residual composition in place of the water content. A composition in which the total amount is a pressure-sensitive adhesive (54.9 to 99.9% by weight) may be used as a pesticide applied to a sheet-like or tape-like substrate.

[0008]

The insecticide according to the present invention, when it comes into contact with adult pests such as cockroaches, ants, termites, flies, mosquitoes, and fleas, does not hinder the behavior of the insects on the insect body surface due to its adhesive force immediately. By adhering enough and penetrating into the body or being taken in as a diet, female adults sterilize it, and male adults sterilize it by transmitting the compound to female adults mated with it. In addition to increasing the number of individuals that have lost their reproductive ability, by causing male adults to die or shortening their lifespan,
Eventually, it exhibits an epoch-making effect of reducing the pest population.

[0009] That is, by contacting the insect juvenile hormone-like compound or ingesting it as a diet, the adult female pest is sterilized and loses its reproductive ability. However, since other males attempt to mate with this female, they become males. It has two effects: a reduction in the reproductive capacity of the side. The adult male pest is not sterilized by incorporating the compound, but the female adult mated with the compound becomes infertile, so that it is possible to transmit sterility to a plurality of females. further,
Male adults that have taken up the compound will die due to the properties of the compound or undergo a new, previously unreported effect of shorter lifespan than normal males.
