Detailed description

In order to make the object, technical scheme and advantages of the invention more clear, the invention will be described in further detail below when taken in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended to explain the invention only and are not intended to limit the invention.

Referring to Fig.1, The embodiment of the invention provides a helping migration device for natural enemy insect, The device comprises a ceiling 1, a trapping light source 2 arranged under the ceiling 1, a funnel 3 arranged under the trapping light source 2, an insect collecting cage 4 connected with the lower end of the funnel 3, and a plurality of insect stopping plates 5 arranged around the trapping light source 2. Each insect stopping plate 5 is arranged radially along the trapping light source 2, and one end of the trapping light source 2 is connected with the ceiling 1, and the other end is connected with the funnel 3.

Specifically, natural enemy insects in the crops are generally trapped into the insect collecting cage 4 7-15 days before harvesting the crops, and released to crops lacking natural enemy insects or crops in the transfer field. When new crops are planted after the harvested crops are harvested, the natural enemy insects in the transfer field can be trapped again and released to the new crops.

During trapping, the device is generally placed in the field, and the trapping light source 2 is turned on in the evening, and the trapping light source 2 is turned off in the morning of the following day, and the collected natural enemy insects are released into crops lacking natural enemy insects or crops in the transfer field, or into nearby crops that have not reached the harvest period.

The ceiling 1 of the present invention is mainly used for protecting from rainwater, when collecting, the trapping light source 2 generates trapping light. As the insect stopping plate 5 is arranged radially relative to the trapping light source 2, it only stop a very small amount of trapping light. At the same time, its bottom is connected with the funnel 3 and its top is connected with the ceiling 1, thus supporting the overall structure.

As shown in that figure, the funnel 3 of this embodiment comprises a funnel body 31 whose cross-sectional area is gradually reduced from top to bottom and an insect collecting port 32 connected to the lower end of the funnel body 31, A low end of that insect stopping plate 5 is connected with the inn wall of the funnel body 31, and the insect collecting port 32 is connected with the insect collecting cage 4. Connecting the lower end of the insect retaining plate 5 with the inn wall of the funnel body 31 can prevent natural enemy insects after colliding with the insect stopping plate 5 from falling outside the funnel 3, which is beneficial to improving the collection efficiency of natural enemy insects. When setting up, as that number of the insect stop plates 5 of the present embodiment can be set according to the need, For example, three, four, five, six or more or more insect stopping plates 5 are uniformly arranged around the trapping light source 2. Since the insect stopping plate 5 have a certain thickness, the more insect stopping plates 5, the greater the stopping effect on light. However, too few insect stopping plates 5 cannot better stop the trapped natural enemy insects and make them fall into the funnel 3. In order to facilitate better connection between the insect stopping plate 5 and the funnel 3, In this embodiment, the funnel body 31 can be arranged as a regular polygon with a circular cross section or matching the number of insect barriers 5, and when the funnel body 31 is arranged as a polygonal funnel body 31, each insect stopping plate 5 can be matched and connected to one corner of the funnel body 31. Specifically, as shown in Fig. 2 and 3, when the insect stopping plate 5 are arranged to be three, in order to facilitate the trapped natural enemy insects to better fall into the insect collecting cage 4, the funnel body 31 can be arranged to have a circular or triangular cross section, and when the insect barriers 5 are arranged to be triangular, the corresponding insect barriers 5 can be connected to the three corners of the funnel body 31; As shown in Fig.4 and

Fig.5, that cross section of the funnel body 31 may be set to be circular or square when the four insect stopping plates 5 are set, and when the four insect stopping plates 5 are set to be square, the lower ends of the four insect stopping plates 5 are respectively connected to the four corners of the funnel body 31. Furthermore, the funnel body 31 of the present embodiment is preferably provided with a circular, triangular or square cross-section. It should be noted that when the cross-section of the funnel body 31 is a regular polygon, the insect stopping plate 5 can be fitted to the middle of either side of the funnel body 31, so that it can better collide with natural enemy insects and cause them to fall into the insect collecting cage 4, which is a conventional deformation of the present embodiment and will not be described in detail here.

In order to facilitate the release of the natural enemy insects in the insect collecting cage 4, the insect collecting cage 4 and the insect collecting port 32 can be detachably connected, i.e. After the collection is completed, the insect collecting cage 4 can be removed from the insect collecting port 32 of the funnel 3 and then released, which is beneficial to improving the release efficiency.

The trapping light source 2 described in this embodiment is preferably arranged as a vertically arranged LED lamp tube, The LED lamp tube can emit yellow-green light with a wavelength of 495-605nm or blue light with a wavelength of 340-562nm. The yellow-green light with a wavelength of 495-605nm is mainly used for trapping natural enemy insects of Hymenoptera and Diptera, while the blue light with a wavelength of 340-562nm is mainly used for trapping natural enemy insects of Coleoptera. Different natural enemy insects are trapped by light sources with different wavelengths, which is beneficial to improving trapping efficiency. Therefore, when the trapping light source 2 is arranged, it can be detachably connected with the ceiling 1, so as to replace different trapping light sources 2 according to the needs of trapping natural enemy insects.

In order to facilitate the trapped natural enemy insects to better fall into the funnel 3 after collision, the distance from the insect stopping plate to the trapping light source 2 is 3-5cm.

As natural enemy insects need to be built into the insect collecting cage 4 for a certain time after falling into the insect collecting cage 4, in order to improve the air permeability of the insect collecting cage 4, the insect collecting cage 4 is made of gauze. In addition, in order to facilitate the survival probability of natural enemy insects in the insect collection cage, a proper amount of litter can be placed in the insect collection cage before trapping. On the one hand, it can supplement nutrition for natural enemy insects, on the other hand, it can be used for trapping pests to lay eggs, and the eggs of pests can also be parasitized or fed by natural enemy insects.

As some natural enemy insects prefer green, such as ladybug and lacewing, in order to improve the trapping efficiency, the outer surfaces of ceilings, funnels, insect barriers and insect collecting cages can be painted green.

The helping migration steps of the embodiment is as follows: The trapping device is placed in the field of the crops to be harvested, Place a proper amount of dead branches and fallen leaves in the insect collecting cage, turn on the trapping light source, and trap natural enemy insects into the insect collecting cage, turn off the trapping light source after collection, disassemble the insect collecting cage from the funnel, and release the collected natural enemy insects into crops lacking natural enemy insects or crops in the transfer field.

The above-described specific embodiments of the present invention do not constitute a limitation of the scope of protection of the present invention.
