Description

  The present invention relates to a beneficial insect collecting apparatus and a beneficial insect collecting method for collecting beneficial insects, and more particularly, to a beneficial insect collecting apparatus and a beneficial insect collecting method for collecting flying natural enemy insects such as Gibberella wasp.

  Conventionally, agrochemicals (chemical pesticides), which are chemicals, have been sprayed in order to remove pests when growing crops. On the other hand, instead of spraying chemical pesticides, a method is also used in which natural enemy insects (beneficial insects) are introduced as pesticides against pests and the pests are exterminated. If this method is used, it is said that there is no problem of residual pesticides and safety is higher than the method using chemical pesticides.

  For example, in the cultivation of vegetables such as eggplants and peppers, food damage due to peach aphids, potato aphids and the like occurs. For the aphids, which are pests of these diseases, Giaf brabachi is known as a flying natural enemy insect. Giant wasp is a parasitic bee that inhabits East Asia such as Japan, Taiwan, China and the Korean Peninsula. This species is known to mainly infest peach aphids and potato aphids. It is an indigenous species and can be collected domestically.

  However, various traps have been proposed for capturing insects (see, for example, Patent Document 1 and Patent Document 2), but most devices and methods for collecting beneficial insects have been disclosed. The current situation is not. If it takes too much time and labor to collect and grow beneficial insects, it will be difficult to substitute chemical pesticides. Against this background, in order to popularize biological pesticides that replace chemical pesticides, there has been a demand for a method that can easily collect beneficial insects at a lower cost.

The light of the wavelength which shows the attractiveness with respect to the beneficial insect X will be emitted toward the exterior.

  Examples of the side surface 2 having translucency include a metal mesh and a transparent resin. If the light from the colored body 10 can be emitted toward the outside of the main body 4, the material of the side surface 2 is used. Etc. are not particularly limited. For example, a transparent mesh made of resin can be used.

  In addition, the colored body 10 is not particularly limited as long as it can emit light having a wavelength exhibiting attractiveness to the beneficial insect X, and examples thereof include a semiconductor light emitting element and a light emitting diode.

  On one side of the main body part 4 according to the beneficial insect collecting apparatus 1 of Embodiment 1, an opening collecting part 8 communicating with the opening end 6 is formed. The beneficial insects X that inhabit the outside of the cultivation facility 20 are attracted by the light emitted from the colored body 10 toward the outside of the main body 4 and enter from the opening end 6, and enter the main body 4 through the opening collecting portion 8. Will be guided to.

  The beneficial insect X guided into the main body portion 4 proceeds to the discharge portion 14 communicated with the other opening end 12 of the main body portion 4 and is finally guided into the cultivation facility 20 from the other opening end 12. The Rukoto.

  Here, for example, when the agricultural products P cultivated in the cultivation facility 20 are eggplants, peppers, etc., the agricultural products P are caused to be damaged by insect pests Y such as peach aphids and potato aphids. For these aphid pests Y, flying gibber wasp is suitable as the beneficial insect X. Gibber wasp (beneficia X) is known to infest aphids (pest Y) such as the peach aphid and the potato aphid, and the density control of the aphids can be controlled by infesting the aphids. It becomes possible.

  Therefore, in order to actively attract the Giant wasp, which is the beneficial insect X of the aphid (pest Y), by the beneficial insect collecting apparatus 1 of the first embodiment, the peak wavelength of the colored body 10 is set to 350 nm to 600 nm. Is more preferable, and 450 nm to 550 nm is more preferable. Although the preferable range of the peak wavelength of the colored body 10 will be described in an experimental example described later, at least when the peak wavelength of the colored body 10 is outside the range of 350 nm to 600 nm, the attracting rate of the Gibberella is reduced, and the collection efficiency Is bad.

  According to the beneficial insect collecting apparatus 1 of the first embodiment having the above-described configuration, the Giant wasp that is the beneficial insect X of the aphids (pest Y) generated in the agricultural products P such as eggplant and bell pepper is external to the cultivation facility 20.

  In addition, in the beneficial insect collecting apparatus 1 of the first embodiment, the second insect Z that is the host of the beneficial insect X but different from the harmful insect Y is eaten on the outlet side of the discharge unit 12 (in the cultivation facility 20). The host plant Q to be placed can also be arranged. The host plant Q is a plant different from the crop P to be protected from the pest Y. Further, the second insect Z that eats the host plant Q does not become a pest for the crop P that it wants to protect from the pest Y. In this way, by causing the beneficial insect X parasitic on the second insect Z to be attracted to the outlet side of the discharge unit 14 without causing the feeding damage by the second insect Z, the beneficial insect X can be further transferred. It is possible to promote guidance into the cultivation facility 20.

Such an example is shown in FIG. In this example, eggplants, bell peppers, and the like are cultivated in a greenhouse that is the cultivation facility 20, and wheat, for example, wheat, is planted as the host plant Q in the vicinity of the outlet of the duct-shaped discharge unit 14. By doing in this way, the wheat aphid which is the second insect Z that eats the wheat (host plant Q) gathers in the wheat, and the Giaf brabachi (beneficial insect) hosting this wheat aphid (second insect Z) The effect of attracting X) occurs. As a result, it can function as a crop trap using the host plant Q.
(Embodiment 2)

In FIG. 3, the schematic sectional drawing of the beneficial insect trap 1a which concerns on Embodiment 2 of this invention is shown. The beneficial insect collecting apparatus 1a according to the second embodiment shown in the figure further includes a fan 24 in the opening collecting unit 8. A fan 24 is disposed in the opening collecting portion 8 to generate an air flow from one opening end 6 of the main body portion 4 to the other opening end 12. With this configuration, the beneficial insect X attracted by the light emitted from the colored body 10 is actively guided from the opening end 6 of the main body portion 4 into the main body portion 4 and smoothly guided toward the other opening end 12 side. be able to.
(Embodiment 3)

  In the beneficial insect collecting apparatus 1a according to the second embodiment of the present invention, the fan 24 is provided on the opening collecting unit 8 side which is the suction side, but the position where the fan 24 is provided is not necessarily limited to the suction side. It can also be provided on the discharge side. Such an example is shown in FIG. 4 as Embodiment 3 of the present invention. In the beneficial insect collecting apparatus 1b according to the third embodiment shown in the figure, a fan 24 is disposed in the vicinity of the other opening end 12 in the discharge portion 14. Also with this configuration, it is possible to generate an air flow in the direction from one opening end 6 of the main body 4 to the other opening end 12. Therefore, it is possible to positively guide the beneficial insect X attracted by the light emitted from the colored body 10 from the opening end 6 of the main body portion 4 into the main body portion 4 and smoothly to the other opening end 12 side. it can.

  Even without a fan, beneficial insects can be guided to beneficial insect collectors and cultivation facilities by natural convection. In particular, by keeping the inside of the cultivation facility in a reduced pressure state compared to the external environment, natural convection occurs in the opening collecting part of the beneficial insect collecting device communicated with the inside of the cultivation facility, and cultivation through the beneficial insect collecting device is performed. Guidance and intrusion into the facility will be promoted.

Furthermore, the position where the opening collecting part is provided is also the end face side of the cylindrical main body part in the above example, but it is not limited to this position, the mesh provided on the side face is enlarged, and the beneficial insects pass through the mesh. You may enable it to enter the main body. In this case, the side surface of the main body portion becomes an opening collecting portion, closes the edge on the upper surface side of the main body portion, and communicates with the edge on the lower surface side. Alternatively, by providing a fan at the upper edge, and forcing the air to be blown to the lower side of the main body by the fan, the mesh-shaped opening collecting portion and the upper surface opened on the side surface It is also possible to guide the beneficial insects from the main unit to the cultivation facility through the fan from the side.
(Embodiment 4)

In the above-described embodiment, an example in which a light emitting body capable of color light emission such as an LED is used as a colored body that serves as a beneficiary attracting medium has been described. However, the present invention is not limited to this, and colored paper can also be used. Such an example is shown as a fourth embodiment in the perspective view of FIG. In this example, a cylindrical main body 4 ′, a plurality of colored plates 10 ′ arranged inside the main body 4 ′, and a light source 10 ″ for irradiating illumination light to the colored plates 10 ′ are provided. The main body 4 ′ is made of a light-transmitting resin, and the side surface is integrally formed with a resin in a mesh shape, and the mesh is used as an opening collecting portion 8 ′ for taking in the beneficial insect X.
(Coloring plate 10 ')

  The colored plate 10 ′ is a plate colored in a predetermined color in advance. The colored plate 10 ′ is irradiated with illumination light from the light source 10 ″ to make it stand out. In this way, the effect of attracting beneficial insects can be exhibited using light having a specific wavelength similar to that described above.In the example of FIG. Although the columns are arranged upright and spaced apart from each other, the shape, number, and arrangement of the colored plates can be appropriately changed to a mode in which beneficial insects are easily visible. The light source 10 ″ is not limited to one. Depending on the number and arrangement of the colored plates, a plurality of these can be prepared so that they can be efficiently illuminated, and the irradiation angle can be adjusted. Furthermore, in this example, the example in which the colored plate is colored in advance with a color that has a high effect of attracting beneficial insects has been described. For example, the emission color of the light source itself is light having a wavelength with a high attracting effect, while the colored plate is white. As an alternative, the display color of the colored plate may be changed by irradiating white colored light with illumination light having such a wavelength. In this case, by changing the light of the light source, the color of the coloring plate can be made variable, and there is an advantage that it can cope with various beneficial insects. As the light source, a semiconductor light emitting element such as an LED can be suitably used. In particular, if a light source that combines three colors of RGB LEDs is used, the emission color can be varied, and the color of the coloring plate can be accommodated.

  As mentioned above, although various embodiment of the beneficial insect collection apparatus of this invention was explained in full detail, embodiment of the beneficial insect collection apparatus of this invention is not limited to said thing. For example, in the beneficial insect trapping apparatus 1 according to Embodiment 1 of the present invention, an odor generating unit that generates the host odor of the beneficial insect X may be further provided. By arranging the odor generating part for generating the odor of the host of the beneficial insect X, the attractiveness of the beneficial insect X by the beneficial insect collecting device 1 can be further enhanced. The position where the odor generating unit is disposed is not particularly limited. For example, the odor generating unit is disposed in the opening collecting unit 8 or the main body 4, the discharge unit 14, the outlet side of the discharge unit 14, or the like. Also good.

Next, the attractiveness of beneficial insect X by the beneficial insect collecting apparatus of the present invention will be described based on experimental examples. In each of the following experimental examples, the attractiveness of Gibber wasp which is a beneficial insect X of aphids (pest Y) generated in agricultural products P such as eggplant and bell pepper was examined.
(Experimental example 1)

  The response reaction of Gibber wasp (Masushiki X) to LED light was examined. In the response reaction test, a transparent plastic cylinder (diameter: about 10 cm × length: about 100 cm) was used. From the center, 20 adult female Giant wasps were introduced, and the number of moving female adults within 10 cm from the light source was investigated 60 minutes after the lighting of the LED monochromatic light placed on one end. In addition, starved female adults were also investigated. The test was conducted in a constant temperature room (room temperature: 20 ° C., humidity: about 70%, dark condition) with 5 types of LED monochromatic light (peak wavelengths of 375 nm (ultraviolet), 470 nm (blue), 525 nm (green), 570 nm (yellow)), The test was repeated three times for each 660 nm (red), all manufactured by Nichia Corporation.

As a result, response responses of each female adult to each LED monochromatic light are shown in FIG. 5 and FIG. In each figure, the attraction rate (%) = the number of localization within 10 cm from the light source / the number of insects × 100, and a high-speed spectroscopic unit (HSU-100S, manufactured by Asahi Spectroscopic Co., Ltd.) was used for measuring the light intensity. In the adult female Giant wasp, light with peak wavelengths of 375 nm, 525 nm and 570 nm was strongly attracted compared to other lights. There was no significant difference in response response depending on the presence or absence of food for each LED monochromatic light.
(Experimental example 2)

  The response response to the color of Gibberella wasp (Benmark X) was examined. For the response reaction test, 6 colored papers (standard colored paper (JIS standard) 20 colors, 9 × 6.5 cm) were used. Each colored paper was covered with an OHP film, sprayed with an adhesive (trade name: gold dragon), and arranged in a plastic cage (60 × 60 × 60 cm). Thirty adult males and females were placed in the cage in the cage, and the number of captured animals was examined after 6 hours. The test was repeated 6 times in a temperature-controlled room (room temperature: about 20 ° C., humidity: about 70%).

  As a result, the reaction of each adult to each colored paper is shown in FIG. The same alphabet in Tukey's multiple comparison indicates that there is no significant difference at a significance level of 5%. Both male and female showed high reactivity in the order of 10Y8 / 12 (yellow), 5GY7 / 12 (yellowish green), 10GY6 / 10 (yellowish green), 5Y8 / 14 (yellow).

Further, the reflection wavelength of each colored paper is shown in FIG. For the measurement, a high-speed spectroscopic unit (HSU-100S) diffuse reflection unit manufactured by Asahi Spectroscopic Co., Ltd. was used. The reflection wavelength peak of each colored paper was 551 nm for 10Y8 / 12, 543 nm for 5GY7 / 12, 533 nm for 10GY6 / 10, and 580 nm for 5Y8 / 14.
(Experimental example 3)

  The trapping effect of Gibber wasp (beneficia X) by the LED trap (light source 10) was examined. In the capture effect test, two LEDs were selected from the LEDs with the peak wavelengths of 375 nm, 525 nm, and 570 nm and the three types of LEDs, which had a high attractiveness in the experimental example 1, and the same number of traps were used, investigated. Moreover, the influence by light intensity was investigated using LED with a peak wavelength of 525 nm. In the test, an LED trap was installed at a height of 1 m in a facility where adults were generated, and the number of captures was investigated every 3 days. In addition, 30 bullet-type LEDs were attached to the base of the LED trap, covered with a styrene square case (194 × 104 × 26 mm), and covered with an OHP film sprayed with an adhesive on the front surface. A polycarbonate material (diffusion angle 60 °) was used for the diffusion plate.

The results are shown in FIGS. In monochromatic light, the peak wavelength of 525 nm was stronger than 375 nm and 570 nm, and it was stronger than the mixed wavelengths of 375 nm and 570 nm, or 525 nm and 570 nm, respectively. As a result of investigating with a trap in which the light intensity was adjusted to three levels in the LED of 525 nm, the attracting property was higher as the light intensity was increased, and the female was particularly remarkable.
(Experimental example 4)

  We investigated the capture effect of Gibber wasp (beneficia X) by the combined use of LED traps and trap crops. In the capture effect test, a wheat aphid (second insect Z) was generated in wheat (cultivar Ayahikari) (host plant Q) grown on a planter (hereinafter referred to as crop trap), and each of the following traps was 30 cm. In each direction, the number of adult Giant wasp was captured every 7 days. For the trap, direct light with a peak wavelength of 525 nm LED, reflected light with respect to the colored paper trap (yellow green (5GY7 / 12)) of the same 525 nm LED, colored paper trap (yellow green (5GY7 / 12)) is used. Only OHP film was used. In addition, a test section for only direct light from an LED having a peak wavelength of 525 nm was provided to investigate the effectiveness of the crop trap.

  The results are shown in FIGS. Both direct light and reflected light having a peak wavelength of 525 nm were captured more than colored paper, and there was no significant difference between the two. Moreover, since the number of captures was small in the test group with only the LED, it was shown that the combined use of the LED and the crop trap is preferable for the attraction.

  The beneficial insect collecting apparatus and beneficial insect collecting method of the present invention can be applied to the aphid parasitoid beetle, cotton scallop, Japanese scourer, naker croaker, and the like, in addition to the Giant syllabus.
