[Industrial applications]
TECHNICAL FIELD The present invention relates to an insecticide for insects such as cockroaches, ants, termites, flies, mosquitoes, flies, flies, mites, and fleas.
[0002]
[Prior art]
Insect juvenile hormone (hereinafter abbreviated as JH) works together with molting hormones to control insect metamorphosis. Insects are most sensitive to JH during the last instar larva stage, when larvae undergo dramatic metamorphosis from larvae to pupae or larvae to adults, and when excessive JH is given during this period, pupal death and abnormal metamorphosis are inhibited. Cause death. Accordingly, a concept has been created to apply the method to pest control using a synthetic compound having the same action as JH (hereinafter abbreviated as JHM), 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 an action that inhibits the synthesis of new cuticles during insect molting and causes death, and has an action completely different from that of JHM. Both have a completely new action different from conventional insecticides and are relatively safe for mammals and exert their specific effects on insects. Often done.
[0003]
The main effect of these two insect growth regulators on insect pests is the larvicidal effect by inhibiting molting and metamorphosis as described above, but also has an infertility effect that reduces the reproductive ability of adults It is known.
[0004]
However, the method of treating these insect growth regulators currently being carried out is exactly the same as the conventional method of treating insecticides (for example, spraying on livestock dung in fly control, and aerosol in cockroaches and flea control). The use of such conventional insect growth regulators in accordance with the conventional methods could not be expected to exert an infertile effect on adult pests. The reason for this is that it was necessary to incorporate a large amount of the drug into the pest in order to provide a sterile effect to the adult pest by the conventional insect growth regulator, and furthermore, the conventional treatment method resulted in the sterility effect It was not possible to make the necessary amount of drug taken into the pest. See also Masner et al. As reported in (1968), the infertility effect of insect growth control is high for females, but lower for males. Could not be expected to have any effect on adult males.
[0005]
[Problems to be solved by the invention]
As described above, in the conventional technique, it is possible to effectively sterilize adult pests, further exert an effect not only on female adults but also on male adults, and bring the female adults mated with this into an infertile state. There has been no task to provide a pesticidal agent which does not have an agent capable of causing insects, and is capable of incorporating an insect juvenile hormone in an amount sufficient for sterilization of an adult.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, in a pest control agent containing the following insect juvenile hormone-like compound as an active ingredient, an adhesive is added to the pest control agent to adhere to the body surface of the pest Was given.
[0007]
Isopropyl (2E-4E) -11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate, 2- [1-methyl-2- (4-phenoxyphenoxy) ethoxy] pyridine, propionaldehyde Oxime 0-2- (4-phenoxyphenoxy) ethyl ether, propionaldehyde Oxime 0-2- (4-phenoxyphenoxy) propyl ether, 0-ethyl N- [2- (4-phenoxyphenoxy) ethyl] carbamate and 1- One or more insect juvenile hormone-like compounds selected from the group consisting of (4-ethylphenoxy) -6,7-epoxy-3,7-dimethyl-2-octene.
[0008]
The insecticide is composed of an insect juvenile hormone-like compound 0.1 to 5% by weight, an adhesive 0.1 to 20% by weight, a sugar 0 to 20% by weight, a protein 0 to 20% by weight, and a pheromone 0 to 0.1%. % By weight and the remaining component as water to form a liquid composition, or a gelling agent by further adding 0.5 to 10% by weight of a gelling agent, or the remaining amount in place of the water content. The composition as an adhesive (54.9 to 99.9% by weight) may be used as a pesticidal agent applied to a sheet or tape-shaped substrate.
[0009]
[Action]
When the insecticide according to the present invention comes into contact with an adult insect such as cockroaches, ants, termites, flies, mosquitoes, and fleas, the insecticide immediately adheres to the insect body surface in an amount sufficient to prevent the insect's behavior due to its adhesive force. The female adult sterilizes it by penetrating into the body or being taken in as a diet, and the male adult sterilizes it by transmitting the compound to the female adult mated with the female adult, thereby having a reproductive ability. In addition to increasing the number of individuals that have lost the insects, the present invention has the epoch-making effect of causing male adults themselves to die or shortening their lifespan, eventually resulting in a decrease in the pest population.
[0010]
In other words, by contacting or feeding with insect juvenile hormone-like compounds, the adult female pest is sterilized and loses its reproductive ability, but further males breed because they attempt to mate with this female. It has two effects: a decline in ability. 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. In addition, adult males incorporating the compound may die due to the properties of the compound or undergo a new, previously unreported effect of shortening their lifespan compared to normal males.
