Method for releasing field natural enemies by using fibrous material as carrier

Abstract

The invention relates to a method for releasing field natural enemies by using a fibrous material as a carrier, which comprises the following steps of: taking the fibrous material as the carrier, rolling the fibrous material into a sphere or any shape, and putting the sphere or any shape into a feeding container filled with predatory mites or natural enemy insects which are being fed; the feeding container can be a packaging bottle or a closed packaging container, a bottle cap of the packaging bottle or a cover of the closed packaging container is provided with a ventilated net cover, and the cover is tightly covered to prevent the predatory mites or the natural enemy insects from escaping; the fibrous materials can also be cotton threads, chemical fiber threads, woolen yarns, paper slips, plant fibers and other similar materials as release carriers; after several days, when the release carriers are full of the required or set density of the predatory mites or other natural enemy insects, the release carriers are taken to the field to be released. The natural enemy release carrier is placed in places where fibers and paper slips can be hung, such as flowers, fruits, branches, barbed strips and the like of plants, so that the natural enemy successively climbs to branches and leaves of crops from the release carrier to eat mites and pests. The method is suitable for crops with serious piercing-sucking pests such as thrips, red spiders, whiteflies and the like, such as blueberries, beans, mangoes and the like.

Description

Technical Field

[0001] The invention relates to a method for releasing natural enemies in the field by using fibrous materials as carriers. Background Art

[0002] Harmful mite pests have caused huge losses to my country's agricultural production. The use of natural enemies to control pests has the characteristics of not polluting the environment and being able to permanently regulate pests. The comprehensive control strategy of harmful mite pests based on biological control technology has been implemented for many years and has achieved remarkable results. The existing methods of releasing natural enemies are: 1. Use hanging bags (bags filled with natural enemies are hung on trees), such as in forests and fruit trees; 2. Sprinkle the natural enemy insects or predatory mites in the bottle on leaves such as tea, vegetables, melons, strawberries, etc.; 3. Use drones to release parasitic bee balls or scatter predatory mites such as rice fields and cotton fields. However, for crops with few or no leaves, such as pitaya, lily, onion, and garlic, the cost of bagging is high, and the effect of spreading in bottles is poor because there are no stretched leaves to support the large number of natural enemies that fall to the ground, increasing the cost of prevention and control. People have been eager and hoping to find a solution to this problem. The inventor has now found a solution to this problem through field investigation, repeated research and experiments. Summary of the invention

[0003] The object of the present invention is to provide a method for releasing natural enemies in the field by using a fibrous material as a carrier. The object of the present invention is achieved by adopting the following technical scheme: the method for releasing natural enemies: using a fibrous material as a carrier, rolling the fibrous material into a ball or any shape and putting it into a breeding container containing predatory mites or natural enemy insects being raised, the lid of the packaging container is provided with a ventilated mesh cover, the mesh cover net is set to have a mesh number of 50 to 400 meshes according to the size of the predatory mites or other natural enemy insects set, and the mesh number can achieve the purpose of being both breathable and preventing the predatory mites or other natural enemy insects from crawling out; closing the lid tightly to prevent the predatory mites or natural enemy insects from escaping; after a few days, when the above-mentioned release carrier is covered with the required or set density of predatory mites or other natural enemy insects, then: a. The breeding container is stored for standby use at a temperature of 8-25 degrees Celsius, with an optimum temperature of 8-15 degrees Celsius. The container should be packed into a box before transportation in summer. During transportation: (1) In summer, the temperature should be kept low to ensure that the temperature is kept at 10-25 degrees Celsius for short distances and 8-15 degrees Celsius for long distances. (2) In winter, the temperature should be kept low to ensure that the temperature is kept at 10-20 degrees Celsius for long distances. b. When the breeding container arrives at the destination, if it is not used on the same day, it must be unpacked and ventilated, and stored in a room with a temperature of 8-25 degrees Celsius for no more than 10 days; c. Place the release carrier made of fibrous material on the branches, thorns and other places where the fibrous carrier can be hung on the flowers and fruits of plants, so that natural enemies (such as predatory mites, ladybug eggs, trichogrammatid eggs, etc.) can gradually crawl from the release carrier to the branches, flowers, stems and other crops of crops to eat harmful mites and pests.

[0004] Compared with the prior art, the advantages of the present invention are as follows: the method of using fibrous materials as carriers to release natural enemies is convenient for sticking to crops, because the fibrous materials as carriers are easy to stick to crops, avoiding the problem that natural enemies (such as predatory mites, ladybug eggs, trichogrammatid eggs, etc.) are directly scattered on the branches and leaves of crops and are easily blown away by the wind or fall to the ground due to gravity, resulting in poor pest control effect. The fibrous materials can also attract wild natural enemies such as predatory mites, ladybugs, and small flower bugs to lay eggs; the present invention has strong targeting of target pests, and the release carrier is directly placed in the place where the pests occur, which can quickly control pests and mites in a short time. After testing, the use effect is very good, and it is simple and easy to operate, saving labor and cost. This method is suitable for crops such as blueberries, beans, mangoes, etc. where thrips, red spiders, whiteflies and other piercing-sucking pests occur seriously. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 A kind of breeding container of the present invention can be a real picture of a packaging bottle.

[0006] Figure 2 This is a photo of the natural enemy release carrier of the present invention placed on the branches of pitaya.

[0007] The numbers in the figure represent: 1-- packaging bottle, 2-- packaging bottle cap, 3-- mesh cover set on the packaging bottle cap, 4--Natural enemy carrier made of fiber material; natural enemy cotton roll, 5--Dragon fruit, 6--Place the cotton roll containing natural enemies at the forks of pitaya, 7--Feeding animals. DETAILED DESCRIPTION

[0008] The present invention is described below with reference to the specific embodiments of the accompanying drawings, but the invention is not limited thereto. Example

[0009] like Figure 1As shown: the fiber carrier is cotton, which is rolled into a ball or any shape and placed in a predatory mite or natural enemy insect breeding container packaging bottle 1. Because the predatory mite is very small and easy to escape, the lid used must be precisely inlaid. Therefore, the outer side of the bottle top on the bottle mouth of the packaging bottle 1 is provided with an outer corrugation, and the inner side of the packaging bottle cap 2 is provided with an outer corrugation. The bottle mouth of the packaging bottle 1 and the packaging bottle cap 2 are provided with a rotating corrugation. The lid is tightened to prevent the predatory mite or natural enemy insect from escaping. The packaging bottle cap 2 is provided with a ventilated mesh cover 3. The ventilated mesh cover 3 is set with a mesh number of 50 to 400 meshes according to the size of the predatory mite or other natural enemy insect set. The mesh number can achieve the purpose of being both breathable and preventing the predatory mite or other natural enemy insect from crawling out; after a few days, when the cotton ball or the above-mentioned release carrier is covered with the required (set) density of predatory mites or natural enemy insects, it is sent to the field for release.

[0010] The fiber carrier can also be replaced by cotton thread, chemical fiber thread, wool thread, paper strip, or plant fiber as a release carrier. Example

[0011] Plastic packaging boxes can also be used as containers for breeding predatory mites or natural enemy insects. Because predatory mites are very small and easy to escape, a card slot-type embeddable structure is adopted between the contact part of the plastic packaging box body and the box cover. That is, the contact part between the packaging box body and the box cover has a convex groove on one side and a concave groove on the other side. The two sides can be embedded with each other to prevent predatory mites or natural enemy insects from escaping. Example

[0012] like Figure 2 As shown: Use tweezers to pick out the release carrier containing natural enemies (such as predatory mites, ladybug eggs, trichogrammatid wasp eggs, etc.), and then put it into the branches, thorns, and other places where fibers and paper strips can be hung on the flowers and fruits of plants, so that the natural enemies (such as predatory mites, ladybug eggs, trichogrammatid wasp eggs, etc.) can gradually crawl from the release carrier to the dragon fruit, and then quickly crawl to the flowers to feed on pests such as thrips.

[0013] This method is suitable for crops such as blueberries, beans, mangoes, etc. where thrips are seriously infested.

[0014] Test example: The invention has good application effect on 1,000 mu of pitaya in Jianfengling Farm, Sanya, Hainan, reducing the amount of pesticide use by 3 to 5 times per season and reducing the prevention and control cost by 30% to 40%.

[0015] The above disclosure is only a specific embodiment of the present invention, but not a limitation of the present invention. Any similar changes made based on the above conception should belong to the scope of the present invention.
