Description

Technical Field

[0001] The utility model relates to a natural enemy insect carrier plant system device, belonging to the technical field of crop pest control. Background Art

[0002] In the prevention and control of agricultural pests, although traditional chemical pesticides can effectively control pests, they can cause harm to the ecology, environment, and other non-target organisms. Among biological control measures, the use of parasitic wasps for preventive biological control of pests has received increasing attention due to its eco-friendliness and high efficiency. Parasitic wasps belong to a group of tiny insects, and their lifestyle usually depends on host insects (pests) to complete their life history. Parasitic wasps will feed on the larvae, pupae, and adults of host pests or use them as a place to breed offspring. The ability of parasitic wasps to accurately locate and control specific pest populations is usually used to effectively control pest populations without affecting other beneficial insects or organisms.

[0003] The existing production and release methods of parasitic wasps are mainly factory production-purchase-release. These release methods are not only costly, but also have problems such as difficult to control the release amount and release time, short duration of parasitic wasp control, and high cost. In addition, the selection of the number and timing of releasing parasitic wasps is also a key factor. If the selection is inappropriate or the release amount is insufficient, the expected control effect may not be achieved; and most parasitic wasps usually have a short lifespan, and after being released and parasitized, they usually cannot form the ability to continuously control pests. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the utility model provides a natural enemy insect carrier plant system device, which can use plants to attract parasitic wasp hosts and introduce parasitic wasp nests into the field, thereby attracting parasitic wasps and helping them expand their populations, so as to improve the sustainability and efficiency of their pest control.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a natural enemy insect carrier plant system device, including a tray box, a rain cover, and a seedling tray. The top of the tray box is equipped with a rain cover through multiple adjustment rods, and the top of the rain cover is equipped with a lifting ring. A seedling tray is installed in the tray box. The seedling tray is a conical structure, and a plurality of seedling holes are arranged on the top. The seedling holes extend to the bottom of the seedling tray and are connected to the tray box. A water-absorbing sponge is also arranged in the tray box, and the water-absorbing sponge is located at the bottom of the seedling tray.

[0006] Preferably, an annular flange is provided on the top circumference of the tray box, and a plurality of adjustment rods are fixed to the bottom of the rain cover. Correspondingly, a plurality of insertion holes are provided on the annular flange, and the bottoms of the adjustment rods are inserted into the insertion holes.

[0007] Preferably, an annular limiting groove is arranged on the top of the inner wall of the tray box, and correspondingly, an annular limiting protrusion is arranged on the top circumference of the seedling tray, and the annular limiting protrusion is stuck in the annular limiting groove.

[0008] Preferably, a cylindrical mesh cover is also installed on the outside of the adjusting rod, an annular fixing plate is fixed to the bottom of the cylindrical mesh cover, an annular plug plate is arranged on the top, a support rod is arranged between the annular fixing plate and the annular plug plate, the annular fixing plate is fixed to the annular flange by screws, and the annular plug plate is inserted in the rain cover.

[0009] Preferably, the cylindrical mesh cover is a 30-mesh nylon mesh.

[0010] Compared with the prior art, the utility model has the following technical effects: the utility model quickly cultivates the carrier plants of the parasitic wasp hosts through the seedling tray, and the carrier plants can naturally attract or increase the parasitic wasp hosts by artificial inoculation of pests. The device is especially used in the early stage of pest occurrence, before the population has grown in large quantities, which can prevent pests from causing large-scale damage to crops, reduce the risk of target pest outbreaks, and effectively reduce economic losses. The use of the device can allow parasitic wasps to establish effective populations in the early stage of pest occurrence, and can achieve better biological control effects. The use of the device to release parasitic wasps does not conflict with the conventional release, and can play a good role in pest control when used alone or as an auxiliary means of conventional release. Preventive biological control is carried out by using carrier plants in the early stage of pest outbreak, and parasitic wasp hosts and parasitic wasps are continuously attracted and expanded, which makes up for the high cost and short duration of bee card release. The device can help parasitic wasps colonize in advance, effectively control pests in the early stage of pest occurrence, reduce the use of chemical pesticides, protect the ecological environment, and bring economic and ecological benefits.

[0011] In addition, the rain cover can effectively protect the plant seedlings from excessive direct sunlight after emergence, and can also provide a favorable place for the bee card to be hung. The seedling hole tray design is conducive to maintaining proper humidity and ventilation so that the seeds can take root and germinate quickly. The water-absorbing sponge can help plants retain moisture and humidity for a long time outdoors, reducing manpower. The 30-mesh nylon gauze can play a protective role and prevent larger predators from harming parasitic bees. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the tray box 1 is equipped with a rain cover 2 through a plurality of adjustment rods 4, and the top of the rain cover 1 is equipped with a lifting ring 5. The tray box 1 is equipped with a seedling tray 3. The seedling tray 3 is a conical structure, and a plurality of seedling holes 6 are arranged on the top. The seedling holes 6 extend to the bottom of the seedling tray 3 and are connected to the tray box 1. A water-absorbing sponge 7 is also arranged in the tray box 1, and the water-absorbing sponge 7 is located at the bottom of the seedling tray 6.

[0016] Among them, an annular flange 8 is provided on the top circumference of the tray box 1, and a plurality of adjusting rods 4 are fixed to the bottom of the rain cover 2. Correspondingly, a plurality of sockets are provided on the annular flange 8, and the bottom of the adjusting rod 4 is inserted into the socket. The adjusting rod can be freely plugged in and out, which is convenient for replacing the seedling tray. An annular limiting groove 9 is provided on the top of the inner wall of the tray box 1, and correspondingly, an annular limiting protrusion 10 is provided on the top circumference of the seedling tray 3, and the annular limiting protrusion 10 is stuck on the annular limiting groove 9. The seedling tray 3 is stuck on the top of the tray box 1 and can be freely disassembled, which is convenient for disassembly and assembly. A cylindrical mesh cover 11 is also installed on the outside of the adjustment rod 4. The cylindrical mesh cover 11 is a nylon mesh of 30 meshes. An annular fixing plate 12 is fixed to the bottom of the cylindrical mesh cover 11, and an annular plug plate 13 is arranged on the top. A support rod 14 is arranged between the annular fixing plate 12 and the annular plug plate 13. The annular fixing plate 12 is fixed to the annular flange 8 by screws, and the annular plug plate 13 is inserted into the rain cover 2. The cylindrical mesh cover 11 is fixed on the frame composed of the annular fixing plate 12, the annular plug plate 13 and the support rod 14, and then installed between the rain cover 2 and the tray box 1, which is simple and convenient to install.

[0017] The utility model uses a seedling tray in a greenhouse to quickly grow carrier plants. After the carrier plants emerge, they are placed in a target location to allow the carrier plants to naturally attract or artificially inoculate host pests of parasitic bees. When used specifically, the carrier plants in the seedling tray can be changed according to the control target, such as breeding plants that attract Lepidoptera (Hemiptera) pests such as wheat, cabbage, and broad beans. At the same time, seedling trays with different numbers of seedling holes can also be used for breeding according to the characteristics of the plants themselves. Secondly, corresponding parasitic bee cards can be hung inside the rain cover according to the target pest type as an auxiliary measure to release the parasitic bees in increments.

[0018] In the process of pest control, the device is placed in the field or orchard, and different parasitic wasp cards and carrier plants are hung according to the characteristics of the pests. When the cards are released, they can be replaced, and the carrier plants can be replanted if they die. The following is an actual control case.

[0019] Taking the prevention and control of Schizaphis pyri in pear orchard as an example, Aphis citrinum can be used as a parasitic natural enemy of the target pest. Before Schizaphis pyri occurs in pear orchard, Aphis rapae can be used to attract and propagate. Moreover, pear trees are not hosts of Aphis rapae and will not harm the health of pear trees. Specifically, before Schizaphis pyri occurs in pear orchard, the carrier plant rapeseed is quickly cultivated in the greenhouse using the seedling pot of the device. When breeding, prepare suitable seedling medium, usually perlite, vermiculite, peat soil, etc., to ensure good drainage and sufficient air permeability. Evenly sow rapeseed seeds in the seedling pot, and the sowing density is determined according to the variety and the size of the seedling pot. Usually, 2-3 seeds are planted in each small hole or small grid. After covering with soil, moisturize and cultivate. Then place the seedling pot in the greenhouse to provide sufficient sunlight and suitable temperature. The suitable growth temperature of rapeseed is generally between 15-25℃. During this period, check the humidity of the seedling pot and the growth of the seedlings, and replenish water in time. If the seedlings are found to be growing too densely, they can be thinned out appropriately to promote healthy growth. When the rapeseed seedlings grow to a suitable stage (generally 3-4 true leaves), the seedlings can be transplanted to the pear orchard for further growth. After being placed in the pear orchard, the rapeseed can naturally attract the rape aphid (or artificially inoculate the rape aphid at 100 heads / plant). The parasitic natural enemy insect, the tobacco aphid braconid, can rely on the chemicals (pheromones) emitted by the rape aphid or visual recognition to find them. Once the tobacco aphid braconid finds the aphid, they will use a long and thin ovipositor to lay eggs into the aphid's body. After the eggs hatch, the larvae of the parasitic wasp will develop inside the aphid, causing the aphid to die. Using the tobacco aphid braconid host rape aphid to attract and expand a large number of tobacco aphid braconids can effectively prevent and control the pear Schizaphis aphid in the pear orchard before the population has grown significantly, reducing the risk of an outbreak of pear Schizaphis aphid in the pear orchard. It also helps the tobacco aphid wasp to establish a stable population, effectively reducing the population and impact of the pear aphid, a pest in the pear orchard.

[0020] Taking the prevention and control of wheat aphids, wheat aphids, and cereal aphids as an example, the device is used to quickly cultivate the carrier plant carrot in the greenhouse before the wheat seedlings head. Carrots like sufficient light, which can promote the healthy growth and root development of carrots. The suitable light condition for carrots is more than 6 hours of sunlight per day. During breeding, nutrient-rich and well-drained humus is used as the seedling soil, and radish seeds are evenly sown in the seedling pot. When the seedlings grow 2-3 true leaves, the first thinning is carried out to remove weak and diseased seedlings, and the soil moisture is maintained during the period. Then transplant it to the wheat field. After the carrots emerge in the field, they can naturally attract carrot microtubule aphids (or artificially inoculate carrot microtubule aphids at 100 heads / plant). Because wheat is not the host of carrot microtubule aphids, it will not harm the health of wheat. Carrots, as carrier plants, can be used to propagate carrot microtubule aphids and tobacco aphid braconids in large quantities. When Macrosiphum wheat aphid, Schizaphis wheat aphid and Grain aphid begin to occur in wheat fields, a large population of the tobacco aphid braconid can effectively prevent and control aphids in wheat fields.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the scope of the present invention.
