Description

  The present invention relates to a member for capturing pests (harmful insects). More specifically, it is necessary to capture pests (for example, southern whiteflies, white spotted whiteflies, silver leaf whiteflies that damage tomatoes, eggplants, melons, etc.). The present invention relates to providing a pest-capturing member that is excellent in property and usability and does not attract a wide range of pests.

  The use of pesticides and insecticides is indispensable for pest control in houses, greenhouses, etc., but so-called pesticide-reducing cultivation in which the use of pesticides and insecticides is reduced due to environmental measures and market demands has been studied. On the other hand, the use of so-called biological pesticides that use living organisms for pest control has begun to become widespread, but it must be costly and careful consideration of the environment of use, such as ecosystem conservation, is necessary. However, the current situation is that it still takes time to expand the spread.

As a pest capturing member for capturing pests, an adhesive sheet colored yellow, blue or pink, which is a pest attracting color (a color having a property of attracting pests), is widely used. In addition, a combination of a pest attractant and a pheromone, and a combination of the above-mentioned adhesive sheet and an ultraviolet lamp are also widely used (see Patent Document 1).
JP 2003-306401 A

  However, in the case of an adhesive sheet colored yellow, blue or pink, which is an attracting color, there is a problem that the trapping ability of pests is affected by the weather during use and the variation in hue in coloring. It was. In addition, when actually capturing pests in a house or greenhouse, an adhesive sheet colored in yellow, blue or pink, which is an attracting color, is used to increase the capture capability. It is necessary to install at intervals, and due to the fact that the installation density of the adhesive sheet has to be set high in this way, the operator is uncomfortable due to work complexity and contact with the adhesive sheet. In addition to this, there is a problem of causing problems due to sticking of the adhesive sheet to plants. In addition, recently, the attracting effect of attracting colors has decreased due to the accustomed use of yellow, blue, or pink colors, which are the colors of whiteflies and thrips. Therefore, the adhesive sheet must be installed for a long period of time. There is a problem that the adhesive effect is easily lost due to adhesion of dust and dust to the adhesive part.

  In addition, in the case of using the attractant described in Patent Document 1, since a general insect is targeted as the attractant, a large effect cannot be expected in terms of catchability, and such attracting is also possible. In the case of using the agent, there is a problem that the attracting agent is volatilized and the usable lifetime is short. In addition, the effective range is limited to the range where the attractant is volatilized and can be perceived by pests, so if you use it in an open place or use a material with a narrow volatilization range (low efficacy), the capture ability will be reduced. On the other hand, there was a trade-off between using a wide range of volatility (high efficacy) as an attractant, which would also attract pests from a wide range. In addition, in the case of using pheromone agent, the range of use is limited to specific pests, and there is a problem that they are not suitable for a wide range of pests, there are restrictions on the installation place and pests are attracted from a wide range . In addition, attractants and pheromone agents are legally treated as pesticides, requiring application for specific pesticides, and there are restrictions on their use. In addition, the use of UV lamps has the effect of attracting UV rays, but when used in a house or greenhouse, it attracts and attracts external pests, so it is rarely used. .

  The present invention has been made to solve the above-mentioned problems, and it is necessary to capture pests. For example, in a house or a greenhouse, it is excellent in pest capture performance (capability) and usability, An object is to provide a member for capturing pests which is not attracted from a wide range.

  In order to achieve the above object, the present inventors have made various studies on insect pattern recognition based on the sensory (visual) physiology of insects, by using a predetermined shape of an ultraviolet reflection layer and / or an ultraviolet absorption layer.

(Ultraviolet reflecting layer and / or ultraviolet absorbing layer)
According to the sensory physiology of insects, insects view the outside with the three primary colors of ultraviolet, blue and green yellow, similar to the three primary colors of visible light in human vision. For this reason, many flowers of plants have a pattern that reflects ultraviolet rays to attract insects. These patterns (recognition patterns) are visible to insects but not to humans. Chrysanthemum and lily flowers are only visible to humans as uniform yellow or white, but there are spots and streaks (recognition patterns) that appear dark around the nectaries, and the spots are ultraviolet rays. As it absorbs, it is conspicuously visible to insect eyes. These spots and muscles are called nectar signs that act as a signpost to teach insects where nectar is. Insects are presumed to capture this dense sign as a figure. When a plant is photographed with an ultraviolet photo, the sprout part, stem hair part, leaf conduit part, active part of the assimilation, etc. are reflected and brightened. It is presumed that insects visually recognize these parts as figures.

  In the present invention, utilizing the visual physiology of insects and the ecology of plants, an ultraviolet reflecting layer 3a and / or an ultraviolet absorbing layer 3b are further disposed on the above-described attracting color layer 2 as an attracting means. This increases the attractiveness of pests.

Further, as shown in FIG. 3, an ultraviolet reflecting layer 3 a and an ultraviolet absorbing layer 3 b may be provided on the attracting color layer 2.

  The shape (outer shape) of the ultraviolet reflecting layer 3a and / or the ultraviolet absorbing layer 3b is, for example, an attractive effect obtained from an ultraviolet photograph of a plant, which has been formed as a lump figure, in order to enhance the attractiveness of pests. It is preferable to select and use a high one. Especially, it is preferable that it is a petal shape, and as shown in FIG. 4, it is more preferable that it is an asteric shape. This is because insects are visually observing the outside world with compound eyes (because the image of the object is identified in a mosaic pattern), and the aggregate of thin lines of UV reflected light is clearly visible to the pests. Is used. FIG. 4 shows a case where an ultraviolet absorbing layer 3b is further disposed on the central portion of the ultraviolet reflecting layer 3a.

  There is no restriction | limiting in particular as an arrangement | positioning method in the attracting color layer 2 of the ultraviolet reflective layer 3a and / or the ultraviolet absorption layer 3b, For example, arbitrary methods can be used from a printing system, a coating system, a sticking system, etc.
