Description

Technical Field

[0001] The utility model relates to the technical field of biological control of agricultural pests, and more specifically to a natural enemy releaser. Background Art

[0002] At present, passion fruit, grapes, kiwi and other trellis plants are often harmed by pests and mites such as thrips, aphids, spider mites, etc. As food safety, environmental protection and biodiversity issues have received more attention, it is imperative to reduce the use of pesticides, and the use of natural enemies to control pests has become an important means of sustainable integrated management. In my country, a variety of natural enemies such as predatory mites, predatory ladybugs, parasitic wasps, etc. have been successfully commercialized and successfully promoted and applied on 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 plane of the trellis. This height makes it difficult to release natural enemies quickly and conveniently, and the release of natural enemies is easily affected by the weather, especially on rainy days.

[0004] Therefore, it is an urgent problem for technicians in this field 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 of trellis plants. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model embodiment discloses a natural enemy releaser.

[0028] Example 1

[0029] 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 four sleeves 3 of equal length. 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 with four short tubes of equal length connected together;

[0030] 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 that of 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.

[0031] 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, and the pivot bases 8 are pivoted to one end of a natural enemy climbing bar 9, and the climbing bar 9 can be twisted along the pivot position.

[0032] 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.

[0033] When the natural enemy releaser is deployed, the collar 7 slides down to the middle and lower part of the sleeve 3, and the climbing strip 9 is deployed to build a bridge on the surrounding plant branches and vines, serving as a path for natural enemy insects to climb to the plants.

[0034] The natural enemy releaser of the utility model not only provides a sunshade and rainproof shelter environment for the natural enemies, but also provides convenient conditions for convenient and rapid release of the natural enemies.

[0035] How to use the releaser (taking predatory mites as an example): Choose the location where the plant climbs up the trellis, hang the releaser in the area where the leaves gather, so that the releaser contacts the leaves as much as possible, and the climbing strips and plant branches and leaves build bridges, one is hung every 6-8 meters, and there are about 12-15 releasers per acre. Pour the matrix mixed with predatory mites into a bowl-shaped container, and the adult, juvenile and nymph predatory mites can all climb out of the container along the skirt-shaped cover and the climbing strips and spread onto the leaves, while the predatory mite eggs can continue to hatch safely in the container and continue to spread when they become active mites. Generally, trellis plants need to release predatory mites 3-4 times a year. When releasing again, just pour the predatory mites into the bowl-shaped container again.

[0036] 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 fields to search for and prey on prey. When releasing trichogrammatids, place the trichogrammatid wasp cards or trichogrammatid wasp balls into a bowl-shaped container. After the trichogrammatids emerge, they will spread to the fields to find and parasitize pest eggs.
