[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for controlling pests using an amphoteric attractant and an insecticide in combination.
[0002]
[Prior art]
Fruit stink bugs are one of the pests that fruit trees want to control. These fruit stink bugs prefer to absorb fruit and cause fruit malformation and fruit dropping. The main source is forests, which infiltrate farms in the process of migration. Currently, control using chemical synthetic pesticides is carried out on the farm, but the control effect is insufficient in the year when the amount of outbreak is large, and it is necessary to take measures against stink bugs before invasion . However, application of chemically synthesized pesticides to forests is problematic from the viewpoint of environmental pollution. Therefore, it is conceivable to collect and kill fruit stink bugs before invading the farm with an attractant such as a sex pheromone agent.
[0003]
However, sex pheromone agents attract only male adults and cannot directly remove female adults that lay eggs of the next generation.
In this regard, research on aggregate pheromones exhibiting an attractive effect on males and females has been advanced, and 2,4,6- as attractants having an attractive effect on males and females of fruit tree stink bugs such as the stink bug Methyl decatrienoate and (E, E, Z) -methyl 2,2,4,6-decatrienoate and an attractant containing them as an active ingredient have been developed (see Patent Document 1). This attractant can be produced, for example, by the method described in Patent Document 2.
[0004]
By utilizing such amphoteric attractants, fruit tree stink bugs are attracted, and the attracted pests are killed by spraying the insecticide, forcibly dropping the surfactant-added water, using an adhesive plate, etc. Can be controlled. Needless to say, the amphoteric attractant can be used not only for insect killing but also for catching outbreaks and the like (for example, see Patent Document 3).
[0005]
On the other hand, there is a method in which an insecticide having systemic transferability is made to penetrate into a cultivated plant, and the insecticide is sucked by a pest to perform insecticide. For example, a method has been proposed in which a nitroimino-based insecticide that has systemic transfer properties and exhibits a sucking-inhibiting effect on stink bugs is applied to the water surface of a paddy field to suppress the production of spotted rice by stink bugs (Patent Reference 4). Patent Document 4 describes imidacloprid and others as the nitroimino insecticide. This imidacloprid is described in Patent Document 5, for example.

[Problems to be solved by the invention]
By the way, in order to kill pests attracted by using the amphoteric attractant, conventionally, spraying of the insecticide, forced drop into water containing a surfactant, use of an adhesive plate, and the like have been performed. However, in the case of spraying the insecticide, there is a problem that the spraying agent has to be repeatedly sprayed frequently to carry out long-term continuous attraction, because the effective period of the spraying drug is short. In addition, in the case of other methods, cost and labor burdens such as frequent water supply, replacement of the adhesive plate, and periodic removal of the induced pests are large, which is an obstacle to implementation.
[0008]
The problem to be solved by the present invention is to establish an effective pest control method in controlling pests that are harmful to cultivated plants, by combining the attraction of pests with an amphoteric attractant and the insect pests with a systemic insecticide. It is in.
[0009]
[Means for Solving the Problems]
The pest control method of the present invention is a method for attracting pests using an amphoteric attractant that attracts male and female individuals of pests that are harmful to cultivated plants, and the components of the insecticide from plants impregnated with a systemic insecticide that is osmotic. It is characterized in that the attracted pest is sucked and the insect is killed by the components of the insecticide.
[0010]
In the pest control method of the present invention, firstly, the use of the amphoteric attractant makes it possible to control pests including adult females that lay eggs for the next generation. Can be effectively reduced. Secondly, by eliminating insect pests that are sucked from the plant impregnated with the systemic insecticide and penetrating the plant, maintenance work for equipment for insecticide is not required, and especially, the permeation by irrigation to the plant is eliminated. Since the effect of the migratory insecticide lasts for a long period of time, continuous pest control can be performed for a long period of time.
[0011]
Third, by combining the use of an amphoteric attractant and the use of a systemic insecticide, pests can be attracted and killed at the plant cultivation site, which is extremely efficient. Specific methods include, for example, irrigating a wettable powder of an osmotic insecticide during cultivation of a plant in soil, and attaching an amphoteric attractant to a branch of the plant with a wire or the like, so that A pest attracted and attracted by the attractant sucks water from the plant and is killed by the insecticide component. Furthermore, by inviting and killing pests around the farm, it is possible to prevent the pests from entering the farm.
[0012]
The pests to be controlled here are mainly fruit tree stink bugs, but also stink bugs that damage soybeans and rice. Examples of the amphoteric attractants of fruit tree stink bugs and stink bugs that damage soybeans and rice include attractants including collective pheromone of Pseudococcidae, collective pheromone of Pseudococcidae, and collective pheromone of southern stink bug. Examples of the systemic insecticide for stink bugs that damage fruit trees, soybeans, rice, and the like include insecticides including imidactprid, thiamethoxam, aceatamipride, dinotefuran, and the like.
By using a combination of the amphoteric attractant and the osmotic insecticide, stink bugs that damage fruit trees, soybeans, and rice can be controlled very effectively.
[0013]
Fruit tree stink bugs include, for example, chabanean stink bugs, wolverine stink bugs, and sting bug stink bugs. These stink bugs prefer to suck fruits such as oranges, pears, loquats, oysters, grapes, plums, and kiwi fruits. In addition, it is said to be the first insect pest to be controlled on the farm, because the beetles and the stink bugs suck soybeans and the like, and the southern stink bugs and blue stink bugs suck the rice ears, soybean seeds, and vegetable fruits. . And the sexes of the German green stink bug are attracted to the collective pheromone of the green stink bug, and the males and females of the beetle and the green stink bug are attracted to the collective pheromone of the green stink bug, and the male and female stink bugs, the male stink bug Has the property of being attracted to the collective pheromone.
[0014]
For example, an attractant containing a collective pheromone of the puppet stink bug, besides the stink bug, can also attract fruit stink bugs such as the stink bug and the stink bug (see Patent Document 3). If the attractant is attached to a plant, fruit stink bugs can be efficiently controlled.
As the usage form of the attractant, a formulation formulated so that a constant amount of the attractant is stably released over a long period of time is suitable.
As the form of use of the systemic insecticide, any of a wettable powder, an emulsion, a water solvent, and a granule can be used as long as the preparation can be sprayed on the soil.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
In the following, a combination of a plant cultivated in soil irrigated with imidacloprid granule wettable powder as an osmotic insecticide and a collective pheromone preparation of Chabanea stink bug as an amphoteric attractant is implemented to control fruit stink bugs Embodiments of the present invention will be described based on examples.
[0016]
[Example 1]
One eggplant (variety name: Chikuyo) was planted in a container (57 × 43 × 32 cm), and when the height reached about 1 m, 7 liters of 2000-fold imidacloprid granule water dispersible solution was irrigated. One day later, Onto the upper branch of the eggplant, a single sticky bug stink bug pheromone preparation (a thin tubular preparation having a length of about 10 cm, manufactured by Shin-Etsu Chemical Co., Ltd.) was attached. On the night of the day, it was observed that the adult C. versicolor stink bug came down after sucking the eggplant. The next morning, 64 adult adult stink bugs were found dead at the eggplant stock plant.
[0017]
[Example 2]
16 days and 47 days after the chemical treatment, the adult planted eggplants were inoculated to adult container-planted eggplants irrigated with 7 liters of 2000-fold imidacloprid granule water dispersible powder, and collected 24 hours later to examine the state of death. As a result, a mortality rate of about 87% was obtained 16 days after drug treatment, and a mortality rate of about 43% was obtained after 47 days, confirming that the effect of the irrigated drug was maintained for a long time.
[0018]
[Example 3]
Under the conditions of Example 1 and the conditions of using a koganecol yellow-type trapping trap (manufactured by Sankei Chemical Co., Ltd.), which is said to have the highest trapping ability of the existing insect traps, it was found that the chabane for 6 days. As a result of investigating the number of deaths of the green stink bug, the average number of deaths per day was about 110 under the conditions of Example 1 and about 90 per day in the yellow trap type trap, and the attracting ability of the method of the present invention. Was confirmed to be high.
[0019]
【The invention's effect】
According to the pest control method of the present invention, by using an amphoteric attractant, it is possible to control pests, including adult females that lay eggs of the next generation, so that by repeating this control, pests can be effectively reduced. Can be done. In addition, since insect pests that are sucked from a plant body impregnated with an osmotic insecticide and sucked are killed, maintenance work for equipment for insect elimination becomes unnecessary, and in particular, osmotic insecticide irrigated with plants is used. Since the effect of the agent lasts for a long time, continuous pest control can be carried out for a long time. Furthermore, by combining the use of the amphoteric attractant and the use of the systemic insecticide, the pests can be simultaneously attracted and killed at the plant cultivation site, and the pests can be controlled very efficiently. Further, by inviting and killing the pests around the farm, it is possible to prevent the pests from entering the farm.
