Description

Technical Field

[0001] The invention relates to a drawer-type parasitic wasp circulation breeding box and a breeding method thereof. Background Art

[0002] Parasitic wasps are the most common type of parasitic insects in farmland ecosystems. They belong to the order Hymenoptera. They parasitize the larvae, pupae and eggs of insects in the orders Lepidoptera, Coleoptera, Hymenoptera and Diptera, allowing their offspring to feed on the hosts for nutrition after hatching and complete their development, while also eliminating the parasitic insects.

[0003] Since most parasitic wasps are natural enemies of pests, people often use them for biological control of pests. For example, the black green wasp can be used to control the pink bollworm, and the middle red side groove braconid can parasitize the Lepidoptera Noctuidae sticky insect, etc. As an important part of sustainable pest control, biological control uses local natural enemy resources to control pests within the allowable level of economic losses in an economical and environmentally friendly way. It has many advantages such as reducing the use of chemical pesticides, slowing down the development of pest resistance, and being environmentally friendly. It will become a hot spot in pest control research in the future.

[0004] The propagation of natural enemies is an important way to carry out biological control. In order to obtain more parasitic bees, it is necessary to carry out a large number of propagation and breeding of parasitic bees, such as a parasitic bee collection and breeding device disclosed in patent CN216906490U. However, most of the existing devices for raising parasitic bees are not sealed, and there is a common problem that parasitic bees are prone to escape during the feeding and changing of materials, and it is not conducive to the collection and treatment of garbage generated during the feeding process such as insect feces and broken materials. In addition, the eggs produced by parasitic bees will also be mixed in garbage such as broken leaves near the parasite, which is not conducive to the effective collection of parasitic bee offspring.

DETAILED DESCRIPTION

[0021] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0022] refer to Figures 1 to 9 A drawer-type parasitic bee circulation breeding box comprises a breeding layer box body 20 with an open upper end, wherein a laterally drawable upper cover body 10 is installed on the upper end of the breeding layer box body, and the upper opening of the breeding layer box body is sealed by the upper cover body; a bee placement hole 22 is provided on one side wall of the breeding layer box body and a sealing mechanism is installed; a detachable filter screen 30 is laterally arranged at the lower end of the breeding layer box body so that garbage can automatically fall into a garbage collection box body of the next layer through the filter screen; a garbage collection box body 40 is detachably installed at the lower end of the breeding layer box body and located below the filter screen to collect garbage in the breeding process, such as insect feces, broken leaves, etc.

[0023] In this embodiment, in order to enable the feeding layer box to be pulled horizontally, first slide grooves 11 are horizontally arranged on both sides of the inner wall of the lower end of the upper cover body, and first slide rails 21 matching the first slide grooves are arranged on both sides of the upper end of the feeding layer box.

[0024] In this embodiment, in order to prevent parasitic bees from flying away when replacing blades, a transverse slot 12 is provided at the lower part of the upper cover body, and the transverse slot extends from the front end of the upper cover body to the rear end inner wall of the upper cover body and is provided with a plug-in plate 50 for being disassembled into the transverse slot to form an isolation cavity in the upper cover body. During the breeding process, when it is necessary to replace blades, the parasitic bees are driven into the upper cover body (the number of male and female parasitic bees is 1:1, preferably 5 pairs), and the plug-in plate is inserted to isolate the parasitic bees in the isolation cavity formed in the upper cover body. Pull the feeding layer box body outward to replace the blades. After the replacement is completed, push the feeding layer box body in again to complete the sealing of the upper port of the feeding layer box body, and finally pull out the plug-in plate.

[0025] In this embodiment, in order to prevent parasitic bees from escaping from the notch of the transverse slot when the plug-in board is not inserted, a cover plate 14 covering the notch 13 of the transverse slot is provided on the front inner wall of the upper cover body, and the upper end of the cover plate is hinged to the upper cover body via a first pin shaft 15, and a first torsion spring with one end abutting against the cover plate is provided on the first pin shaft, and the other end of the first torsion spring is connected to the upper cover body, so that the cover plate always covers the notch of the transverse slot when the plug-in board is not inserted. In another embodiment, if the height of the transverse slot is small, the cover plate may not be provided.

[0026] In this embodiment, in order to make the breeding box breathable, a plurality of air holes 16 are arranged on the top of the upper cover body, and a breathable film 17 is covered on the air holes.

[0027] In this embodiment, in order to prevent the parasitic bees from escaping, the blocking mechanism includes a baffle 23 arranged on the inner side of the feeding layer box body and used to cover the bee placement hole. The upper end of the baffle is hinged to the feeding layer box body via a second pin 24. A second torsion spring 25 with one end abutting against the baffle is arranged on the second rotating shaft, and the other end of the torsion spring abuts against the feeding layer box body, so that the baffle always covers the bee placement hole. When releasing the bees, the baffle is pushed open by the glass tube, and the parasitic bees are placed. When the glass tube is pulled out, the baffle covers the bee placement hole and fits with the inner wall of the feeding layer box body. The bee placement hole can also be used as a finger force point when pulling out the feeding layer box body.

[0028] In this embodiment, in order to make the baffle plate fit more closely with the honeycomb hole, a gasket layer 26 is provided on one side of the baffle plate that fits with the honeycomb hole.

[0029] In this embodiment, in order to facilitate the replacement of the filter screen, a filter screen slot 27 extending from the front end of the feeding layer box body to the rear end inner wall of the feeding layer box body is transversely arranged at the lower end of the feeding layer box body, so that the filter screen can be removed into the filter screen slot. The mesh size of the filter screen is 60 meshes. In addition, the filter screen can be replaced to collect insect eggs.

[0030] In the present embodiment, in order to realize the pull-out cooperation between the garbage collection box body and the feeding layer box body and facilitate the disassembly of the garbage collection box body, the two side walls of the lower end of the feeding layer box body and located at the lower side of the filter slot are laterally provided with a second slide groove 28, and the two sides of the upper end of the garbage collection box body are respectively provided with second slide rails 41 that cooperate with the second slide groove.

[0031] In this embodiment, the upper front side of the feeding layer box body is provided with a first side baffle 29 that protrudes upward and is used to fit with the outer wall of the upper cover body, so that the feeding layer box body and the upper cover body fit more tightly when plugged in. The upper front side of the garbage collection box body is provided with a second side baffle 42 that protrudes upward and is used to fit with the outer wall of the feeding layer box body, so that the garbage collection box body and the feeding layer box body fit more tightly when connected as one.

[0032] In this embodiment, the feeding layer box body, the upper cover body and the garbage collection box body are all made of transparent materials to facilitate observation of the conditions inside each box body.

[0033] In this embodiment, a side wall of the garbage collection box body is also provided with a bee hole and a blocking mechanism for the bee hole, so that the garbage collection box body and the feeding layer box body are common. The blocking mechanism structure on the garbage collection box body is the same as the blocking mechanism structure on the feeding layer box body.

[0034] refer to Figures 10 to 13 In order to prevent the parasitic bees from escaping when the sealing mechanism is opened to place the parasitic bees, the sealing mechanism of this embodiment further includes a silicone sheet 60 and a matching glass tube.

[0035] The glass tube includes a glass test tube 61, a tube cover 62 is provided at the tube mouth of the front end of the glass test tube, a connecting rod 63 is fixedly provided in the middle of the inner end surface of the tube cover, the connecting rod is extended backward along the central axis inside the glass test tube, and the rear end of the connecting rod passes through the through hole on the closed end of the rear end of the glass test tube to the outside, and a pressing end plate 64 is vertically fixedly provided.

[0036] An N-pole magnetic ring 65 is coaxially fixed on the outer edge of the inner end surface of the tube cover, and an S-pole magnetic ring 66 is coaxially fixed on the tube mouth at the front end of the glass test tube for magnetic attraction with the N-pole magnetic ring.

[0037] The glass test tube has a plurality of vent holes 67 on the peripheral wall thereof.

[0038] The silicone sheet is soft elastic silicone, and is arranged on the outer box wall of the bee hole, and the periphery of the silicone sheet is seamlessly connected and fixed to the outer box wall of the bee hole.

[0039] The silicone sheet is provided with an insertion hole 68 at a position corresponding to the honeycomb hole, and the inner diameter of the insertion hole is smaller than the outer diameter of the glass test tube.

[0040] A method for raising a drawer-type parasitic wasp circulation raising box comprises the following steps: S1. Preparation of bee and insect sources: Select healthy egg masses of Spodoptera frugiperda and raise them after hatching; S2. Selection of bee and insect sources: Select young larvae of fall armyworm; S3. Bee breeding: using a drawer-type parasitic bee circulation breeding box, and comprising the following steps: S31. Bee reception: In the feeding layer box, select 2 cm wide corn leaves, access larvae, put in parasitic bees, remove the bee larvae after parasitism; then put in new larvae, and remove the bee larvae after parasitism, and repeat this cycle; S32 Feeding: Take out the bee larvae, add leaves to feed; and the larvae that are not parasitized are raised to pupae (can be carried out in the garbage collection box), collect the pupae after eclosion, pair and lay eggs as the insect source of step S1; S33. Collect and preserve the cocoons.

[0041] In step S1, the bee and insect source preparation is carried out in a feeding layer box. The healthy egg masses of Spodoptera frugiperda are light gray or milky white scales with metallic luster. The incubation temperature is 25°C and the incubation humidity is 80%±5, and the incubation time is 2-3 days.

[0042] In step S1, the post-hatching rearing method includes natural hosts and artificial feeds.

[0043] Natural hosts include corn seed soaking, germination, sowing, and leaf feeding.

[0044] The artificial feed used 600 grams of soybean powder, 480 grams of wheat germ powder, 160 grams of yeast powder, 160 grams of agar, 80 grams of casein, 12 grams of sorbic acid, 30 grams of methyl parahydroxybenzoate, 6 grams of choline chloride, 1.4 grams of inositol, 1.2 grams of cholesterol, 0.4 grams of multivitamin (2 tubes), 50 grams of sodium ascorbate, 6 milliliters of 37.5% formaldehyde, 7000 milliliters of water (3000 milliliters + 4000 milliliters), and 4 bottles of streptomycin.

[0045] Feed preparation method: a. Add 3000ml of water to soybean flour and wheat germ flour, mix well and sterilize at 1*105 Pa pressure for 25 minutes; b. Add 4000ml of water to agar, boil it in a microwave oven until it melts, then pour it into the sterilized soybean powder and wheat germ powder and mix well; c. When the feed temperature drops below 65 degrees, mix yeast powder, casein, methyl parahydroxybenzoate, sorbic acid, cholesterol, inositol, choline chloride, multivitamins, streptotoxin, and sodium ascorbate, add 500 ml of sterilized water to dissolve and pour in, then add formaldehyde, stir thoroughly, divide into packages, cool, and store in a refrigerator at 4 degrees.

[0046] In step S2, select 1-3 young larvae of fall armyworm, with a body length of 1.5 mm to 8 mm, and the best is the body length of 5 mm at the end of the 2nd instar.

[0047] In step S31, in order to prevent the parasitic bees from escaping, the baffle always covers the bee-releasing hole. When it is necessary to continue to release the bees, the baffle is opened through the glass tube and the parasitic bees are released. The specific steps are as follows: Step 1: The parasitic wasps are collected inside a glass test tube, the tube mouth is covered with a tube cap, and the N-pole and S-pole magnetic rings are attracted to each other so that the tube cap and the tube mouth will not separate easily without a certain external force.

[0048] Step 2: Align the end of the tube cover with the insertion hole, and with the assistance of manual operation, make the front end of the glass test tube pass through the insertion hole. At this time, the tube cover cannot push the baffle.

[0049] Since the inner diameter of the through hole is smaller than the outer diameter of the glass test tube, the through hole will be stretched open by the glass test tube to undergo elastic deformation, and the through hole is tightly attached to the outer wall of the glass test tube, so that an escape-proof space is established inside the silicone sheet.

[0050] Step 3: Keep the glass test tube still, and use the pressure on the end plate to push the connecting rod forward. This force overcomes the magnetic attraction of the N-pole and S-pole magnetic rings, so that the tube cover moves forward to open the tube mouth. At the same time, the tube cover is pushed forward to open the baffle, and the parasitic bee is placed in the breeding layer box. During this process, the parasitic bee will not escape due to the barrier of the silicone sheet.

[0051] Step 4: When all the parasitic bees are in the breeding layer box, the staff will pull back the connecting rod, close the pipe mouth and reset the baffle to cover the bee hole, and then remove the glass test tube from the interlaced hole.

[0052] If the words "first", "second" and the like are used in the above invention to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components, and unless otherwise stated, the above words have no special meaning.

[0053] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0054] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the present invention include states or shapes that are approximate, similar, or close to them.

[0055] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.

[0056] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
