Description

Technical Field

[0001] The utility model relates to the technical field of biological control, in particular to a special attracting device for parasitic wasps. Background Art

[0002] Parasitic wasps are the most common type of parasitic insects, and parasitic natural enemies are also the main force in protecting plants from enemies. Most of them are natural enemies of pests and are widely used in biological control.

[0003] As types of parasitic wasps, the existence of the bright-bellied glaze wasp and the Ali lice-eating jumping wasp effectively suppresses the population of citrus psyllids, greatly reducing the chance of citrus psyllids spreading citrus Huanglongbing disease. However, the population of parasitic wasps in nature is not high, and they often lag behind the occurrence of pests. When the pests occur to a certain extent, the number of parasitic wasps will increase, by which time the citrus has already suffered a certain degree of damage.

[0004] Therefore, in the practice of biological control, it is necessary to artificially propagate parasitic bees in large quantities to ensure timely and large-scale supply of the release needs of biological control, so as to achieve the purpose of biological control. When artificially propagating parasitic bees in large quantities, the efficiency and quality of luring and collecting bees are very important. At present, when using suckers to lure and collect bees, since the suckers generate noise and internal heat during use, they are easy to stimulate parasitic bees and cause stress behavior, affecting the survival rate of parasitic bees in the later stage. At the same time, under the action of suction, parasitic bees are easily stuck on the breathable gauze, and the parasitic bees are easily damaged when they are removed, resulting in a high mortality rate of parasitic bees. At the same time, it is time-consuming and labor-intensive, with high labor costs and low collection efficiency of parasitic bees. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a special luring device for parasitic bees in view of the deficiencies of the above-mentioned prior art, which is used for luring and collecting parasitic bees when practicing the propagation of parasitic bees. It will not cause harm or stress behavior to the parasitic bees, has good luring effect and fast luring efficiency, improves the collection efficiency and survival rate of parasitic bees, and reduces the labor cost required for luring and collecting bees.

[0006] The technical solution adopted by the utility model is: a special attracting device for parasitic bees, comprising a cultivation chamber, an attracting and screening chamber and a collecting chamber which are connected in sequence from bottom to top; the bottom of the attracting and screening chamber is closed and connected to the cultivation chamber, and a plurality of attracting holes for parasitic bees to pass through are evenly distributed at the bottom of the attracting and screening chamber, the top of the attracting and screening chamber is detachably connected to the collecting chamber, the top of the collecting chamber is provided with an attracting source, and the attracting source is used to attract parasitic bees to enter the collecting chamber.

[0007] Preferably, a collecting pipe is provided at the bottom of the collecting chamber, and the bottom of the collecting pipe is threadedly connected to the top of the trapping chamber.

[0008] Preferably, the trapping chamber and the collecting tube are made of yellow transparent plastic material.

[0009] Preferably, the attractant source is disposed in the collection chamber and is located 3-5 cm from the top of the collection tube orifice.

[0010] Preferably, the attraction source includes a soft cotton plug arranged on the top of the collection chamber and an attraction tube inserted into the soft cotton plug.

[0011] Preferably, the cultivation room comprises a base and a breathable gauze curtain arranged around the base, and the cultivation room is provided with a cultivation window located at the breathable gauze curtain.

[0012] Preferably, the bee-attracting hole is a trumpet-shaped circular hole that is narrow at the top and wide at the bottom, and the inner hole diameter of the bee-attracting hole is 1.5 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can cultivate and propagate the bright-bellied enameled wasps through the cultivation room, and lure the mature bright-bellied enameled wasps in the cultivation room into the lure and screen room through the lure and screen room whose main body material is yellow transparent plastic, and transfer the bright-bellied enameled wasps staying in the lure and screen room to the collection room through the cooperation of the lure source in the collection room and the collection tube made of yellow transparent plastic material at the bottom of the collection room. The utility model has a simple structure, good lure effect and high lure efficiency, and will not cause stimulation and harm to the collected bright-bellied enameled wasps, thereby improving the collection efficiency of the propagated parasitic wasps and the survival rate of the parasitic wasps, and effectively reducing labor costs.

[0015] 2. The utility model can quickly lure a large number of bright-bellied enameled bees staying in the sieve chamber into the collection chamber, and effectively avoid congestion of bright-bellied enameled bees transferred in the collection tube, by means of a soft cotton plug arranged on the top of the collection chamber and an attractant tube inserted in the middle and on the outer side of the soft cotton plug, wherein the lower end of the attractant tube inserted in the middle of the soft cotton plug is located 3-5 cm above the tube mouth of the collection tube, and the lower end of the attractant tube inserted on the outer side of the soft cotton plug is flush with and tangent to the bottom of the soft cotton plug, thereby effectively shortening the collection time of the mature bright-bellied enameled bees in the collection chamber and accelerating the efficiency of attracting and collecting bees.

[0016] 3. The utility model has a plurality of bee-attracting holes evenly distributed at the bottom of the trapping and screening chamber for parasitic wasps to pass through, and the bee-attracting holes are trumpet-shaped circular holes that are narrow at the top and wide at the bottom, with an inner hole diameter of 1.5 mm. Since the individual size of the bright-bellied enameled wasp is the smallest compared with other insects, only the bright-bellied enameled wasp can enter the trapping and screening chamber through the bee-attracting holes, effectively preventing other insects in the bright-bellied enameled wasp-citrus psyllid-Osmanthus fragrans system from entering the trapping and screening chamber, so that the trapping and screening chamber can accurately attract the bright-bellied enameled wasp with mature forms in the separation and cultivation room.

[0017] 4. The utility model releases an attracting signal by filling the attracting aqueous solution in the attracting tube, so that the mature form of the bright-bellied enameled wasp lured into the attracting screen chamber can be attracted to the collecting tube, thereby preventing the bright-bellied enameled wasp from staying in the attracting screen chamber in large numbers. Under the action of the attracting aqueous solution, temporary food supply can also be provided for the bright-bellied enameled wasp in the collecting chamber for a short period of time, thereby carrying out short-term conservation and improving the survival rate of the bright-bellied enameled wasp.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected" and the like should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] See also Figure 1 The embodiment of the utility model provides a special attracting device for parasitic wasps, which includes a cultivation chamber 1, an attracting and screening chamber 2 and a collecting chamber 3 which are connected in sequence from bottom to top; the larval form of the bright-bellied enameled wasp in the bright-bellied enameled wasp-citrus psyllid-Osmanthus fragrans system is cultivated and propagated through the cultivation chamber 1, thereby ensuring the supply demand of parasitic wasps in the subsequent biological control process.

[0027] In some embodiments, see Figure 1 The cultivation room 1 is composed of a base 101 and a breathable gauze curtain 102 arranged around the base 101. The breathable gauze curtain 102 can prevent insects in the system of the bright-bellied enameled wasp-citrus psyllid-Osmanthus fragrans in the cultivation room 1 from escaping, and ensure sufficient oxygen and suitable temperature in the cultivation room 1.

[0028] In some embodiments, see Figure 1 The cultivation room 1 is provided with a cultivation window 103 at the air-permeable screen 102. It is convenient to timely supplement nutrients to the insects in the system of the bright-bellied glaze wasp-citrus psyllid-Murraya odorifera in the cultivation room 1, and ensure the normal cultivation and expansion of the bright-bellied glaze wasp.

[0029] In some embodiments, the base 101 and the breathable gauze curtain 102 in the cultivation room 1 are detachable, which is convenient for the installation, maintenance and management of the cultivation room 1 and the care of the insects in the system of the glossy-bellied enameled wasp-citrus psyllid-Osmanthus fragrans in the cultivation room 1, thereby ensuring the normal cultivation and expansion of the glossy-bellied enameled wasp.

[0030] In some embodiments, see Figure 1 and Figure 2 The bottom of the luring and screening chamber 2 is closedly connected to the top of the breeding chamber 1. Specifically, the main body of the luring and screening chamber 2 is made of yellow transparent plastic material, and a plurality of bee luring holes 5 are evenly distributed at the bottom of the luring and screening chamber 2.

[0031] Because the bright-bellied enameled wasp has a significant tendency to move toward yellow compared to other insects in the bright-bellied enameled wasp-citrus psyllid-Osmanthus fragrans system in the breeding room 1, the trap chamber 2 can effectively attract the mature bright-bellied enameled wasp in the breeding room 1 to enter the trap chamber 2 from the trap hole 5 at the bottom of the trap chamber 2, thereby preliminarily completing the trapping and collection of the mature bright-bellied enameled wasp in the breeding room 1. The trapping effect is good and the trapping efficiency is high, and it will not cause stimulation and harm to the bright-bellied enameled wasp, thereby effectively ensuring the survival rate of the parasitic wasp.

[0032] In some embodiments, see Figure 2 There are several trumpet-shaped circular holes evenly distributed at the bottom of the trapping and screening chamber 2, which are narrow at the top and wide at the bottom, and have an inner hole diameter of 1.5 mm.

[0033] Because the individual size of the bright-bellied enameled wasp is the smallest compared with other insects in the bright-bellied enameled wasp-citrus psyllid-murraya osmanthus system in the cultivation room 1, only the bright-bellied enameled wasp can enter the trap chamber 2 through the bee trap hole 5, effectively preventing other insects in the bright-bellied enameled wasp-citrus psyllid-murraya osmanthus system from entering the trap chamber 2, so that the trap chamber 2 can accurately lure and separate the mature bright-bellied enameled wasp in the cultivation room 1.

[0034] In some embodiments, see Figure 3 and Figure 4 A collecting tube 301 made of yellow transparent plastic material is arranged at the bottom of the collecting chamber 3, and the collecting tube 301 is threadedly connected to the top of the attracting and screening chamber 2, so as to completely separate the attracting and screening chamber 2 from the collecting chamber 3 later. At the same time, under the action of the collecting tube 301, the bright-bellied enameled wasp staying in the attracting and screening chamber 2 is guided into the collecting chamber 3.

[0035] In some embodiments, see Figure 3 and Figure 4 The collecting chamber 3 is provided with an attractant source 4 at 3-5 cm from the top of the tube mouth of the collecting tube 301.

[0036] Through the coordination of the attraction signal released by the attraction source 4 and the collection tube 301, the bright-bellied enameled wasps staying in the attraction and screening chamber 2 are lured into the collection chamber 3, while maintaining a certain distance and ensuring the attraction effect of the attraction source 4, thereby avoiding congestion of the bright-bellied enameled wasps in the collection tube 301 during the transfer process, so that the bright-bellied enameled wasps can be quickly transferred from the attraction and screening chamber 2 to the collection chamber 3.

[0037] In some embodiments, see Figure 3 and Figure 4The attractant source 4 includes a soft cotton plug 401 disposed on the top of the collection chamber 3 and an attractant tube 402 inserted in the middle and on the outer side of the soft cotton plug 401. Specifically, the attractant tube 402 is a capillary tube filled with an attractant aqueous solution for attracting the bright-bellied enameled wasp. The attractant aqueous solution in the attractant tube 402 can not only release the attractant signal, but also provide temporary food supply for the bright-bellied enameled wasp in the collection chamber 3 for a short period of time, thereby performing short-term care and improving the survival rate of the bright-bellied enameled wasp.

[0038] In some embodiments, the attractant aqueous solution is an aqueous solution containing honey or a aqueous solution containing sugars, so that it can provide nutrients for the bright-bellied enameled wasp while attracting it.

[0039] In some embodiments, see Figure 4 The lower end of the attraction tube 402 inserted in the middle of the soft cotton plug 401 is located 3-5 cm above the tube mouth of the collection tube 301, and the lower end of the attraction tube 402 inserted on the outer periphery of the soft cotton plug is flush with the bottom of the soft cotton plug.

[0040] The attracting tube 402 inserted in the middle of the soft cotton plug 401 can form a central attraction source in the collection chamber 3. Since the bright-bellied enameled wasps often give priority to significant visual or olfactory clues when looking for an attraction source, the centrally protruding attracting tube 402 can better attract the bright-bellied enameled wasps' attention, guide them to quickly locate and enter the collection chamber 3, improve the efficiency of attracting the bright-bellied enameled wasps, and enable them to quickly transfer from the attracting and screening chamber 2 to the collection chamber 3;

[0041] The attractant tubes 402 inserted on the outer periphery of the soft cotton plug can form a uniform odor distribution around the soft cotton plug 401. Since the bright-bellied enameled wasps rely on their sense of smell to perceive the attractant fragrance diffused in the air when searching for the attractant aqueous solution, the evenly distributed attractant tubes 402 can ensure that the attractant aqueous solution evaporates more evenly, so that the bright-bellied enameled wasps can be quickly transferred from the collection tube 301 to the collection chamber 3, avoiding congestion of the bright-bellied enameled wasps in the collection tube 301, which is particularly beneficial for research or application occasions that require rapid and large-scale collection of parasitic wasp bodies.

[0042] In summary, this insertion method of the attracting tube 402 takes into account the attraction, guidance and collection efficiency of the parasitic wasps, which helps to improve the overall effectiveness of the attracting device.

[0043] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
