Description

Technical Field

[0001] The present invention relates to the technical field of biological control of agricultural pests, and more particularly to a natural enemy releaser and application thereof. Background Art

[0002] Currently, trellis crops like passion fruit, grapes, and kiwifruit are often attacked by pests and mites such as thrips, aphids, and spider mites. With increasing attention paid to food safety, environmental protection, and biodiversity, reducing pesticide use is imperative. Using natural enemies to control pests has become a key tool for sustainable integrated pest management. In my country, a variety of natural enemies, including predatory mites, predatory ladybugs, and parasitic wasps, have been successfully commercialized and applied to a variety of crops.

[0003] The height of the trellis plants is generally 1.8-2.5 meters, and the leaves of the plants are mainly flat on the horizontal surface of the trellis. This height cannot facilitate the quick release of natural enemies, and the release of natural enemies is easily affected by the weather, especially on rainy days.

[0004] Therefore, it is an urgent problem for those skilled in the art to provide a natural enemy releaser that is not affected by weather, can quickly release natural enemies, and is suitable for preventing and controlling small pests on trellis plants. Summary of the Invention

[0005] In view of this, the present invention provides a natural enemy releaser and application.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A natural enemy releaser, comprising:

[0008] Hook 1, conical rain cover 2, sleeve 3, bowl-shaped container 4;

[0009] The hook 1 is fixedly connected to the outer conical top of the conical rain cover 2;

[0010] The top end of the sleeve 3 is fixedly connected to the top of the inner cone of the conical rainproof cover 2; the bottom end of the sleeve 3 is fixedly connected to the center of the inner spherical surface of the bowl-shaped container 4.

[0011] Furthermore, the casing 3 is a casing with 4-6 sections of equal length.

[0012] Furthermore, it also includes: a skirt-shaped outer cover 5;

[0013] The upper edge of the skirt-shaped outer cover 5 is fixedly connected to the upper edge of the bowl-shaped container 4 .

[0014] Furthermore, the skirt-shaped outer cover 5 and the conical rain cover 2 have the same inclination angle.

[0015] Further, it includes: natural enemy climbing frame 6;

[0016] The natural enemy climbing frame 6 comprises a climbing frame collar 7, a pivot base 8, and a natural enemy climbing bar 9;

[0017] A pivot base 8 is fixedly provided around the climbing frame collar 7, and the pivot base 8 is pivotally connected to the end of the natural enemy climbing bar 9;

[0018] The climbing frame collar 7 is sleeved on the sleeve 3 .

[0019] The invention discloses an application of a natural enemy releaser in preventing and controlling small pests of trellis plants.

[0020] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the present invention are:

[0021] The natural enemy releaser provided by the present invention can release natural enemies at a trellis height of 1.8-2.5 meters. It can also release natural enemies on rainy days. The climbing strips can be placed on plant branches to guide natural enemy insects to climb onto the plants. The outer cover has a slope parallel to that of the rain shield, and the climbing strips are foldable for easy storage. The skirt-shaped outer cover is slightly smaller than the rain shield to better protect against rain. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0028] Releaser: The main body of the releaser is a conical rain cover 2 and a bowl-shaped container 4 at the lower end, which are connected by 4-6 equal-length sleeves 3. The upper end of the sleeve 3 is fixedly connected to the inner top of the rain cover 2, and the lower end of the sleeve 3 is fixedly connected to the concave center of the bowl-shaped container 4. The sleeve 3 is a retractable long tube made up of four equal-length short tubes.

[0029] The upper edge of the bowl-shaped container 4 is tightly connected to the skirt-shaped outer cover 5, and the inclined surface of the skirt-shaped outer cover 5 is parallel to the inclined surface of the rain cover 2. When the sleeve 3 shrinks, the skirt-shaped outer cover 5 can be stored inside the rain cover 2; the diameter of the skirt-shaped outer cover 5 is slightly smaller than the rain cover 2 to better achieve the purpose of rain protection. The upper end of the rain cover 2 is fixedly connected to the hook 1 to facilitate hanging the natural enemy releaser on the trellis plants.

[0030] The collar 7 of the climbing frame 6 is sleeved on the sleeve 3 and can slide up and down along the sleeve 3. A plurality of pivot bases 8 are evenly distributed around the outer periphery of the collar 7. The pivot bases 8 are pivotally connected to one end of a natural enemy climbing bar 9, and the climbing bar 9 can be twisted along the pivot position.

[0031] When the natural enemy releaser is in the storage state, the collar 7 slides to the top of the sleeve 3, and the climbing bar 9 is stored and fits between the rain cover 2 and the skirt-shaped outer cover 5. A closed space is formed between the bowl-shaped container 4 and the rain cover 2 for storing natural enemies.

[0032] When the natural enemy releaser is unfolded, the collar 7 slides down to the middle and lower part of the sleeve 3, and the climbing strip 9 unfolds to build a bridge on the surrounding plant branches and vines, serving as a path for natural enemy insects to climb to the plants.

[0033] The natural enemy releaser of the present invention not only provides a shelter environment for natural enemies from the sun and rain, but also provides convenient conditions for releasing natural enemies conveniently and quickly.

[0034] To use a releaser (using predatory mites as an example): Choose a location where plants climb onto the trellis and hang the releaser over a concentrated area of ​​leaves, ensuring maximum contact with the leaves. Use climbing strips to bridge the plant branches and leaves, hanging one releaser every 6-8 meters, for a total of approximately 12-15 releasers per acre. Pour the substrate mixed with predatory mites into a bowl-shaped container. Adult, juvenile, and nymph predatory mites will crawl out of the container along the skirt and climbing strips, dispersing onto the leaves. Predatory mite eggs will continue to hatch safely in the container and become active, allowing them to continue spreading. Generally, trellis plants require 3-4 releases of predatory mites per year. For additional releases, simply return the predatory mites to the bowl-shaped container.

[0035] Similarly, when releasing predatory ladybugs, you only need to place the ladybug egg cards into a bowl-shaped container. After the ladybug larvae hatch, they will crawl out of the container along the skirt-shaped cover and climbing bars, and spread to the field to search for and prey on prey; when releasing trichogrammatids, place the trichogrammatid card or trichogrammatid ball into the bowl-shaped container. After the trichogrammatids emerge, they will spread to the field to search for and parasitize pest eggs.

[0036] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
