Technical Field
[0001] This utility model relates to the field of collection device technology, and in particular to a device for artificially collecting large quantities of wheat moth cocoons. Background Technology
[0002] To reduce the damage caused by storage lepidopteran pests and to provide a scientific basis and theoretical guidance for the efficient control of storage lepidopteran pests using the parasitic wasp *Brachystomum esculentum*, laboratory research is needed on the biology and ecology of *Brachystomum esculentum*, its sensitivity to chemical agents, and its relationship with its host. Therefore, indoor subculture and breeding of *Brachystomum esculentum* test populations are necessary. Currently, the technology for large-scale artificial indoor breeding and subculture preservation of *Brachystomum esculentum* is mature, saving a significant amount of manpower and resources. During the rearing process, the wasps need to be manually transferred to new rearing devices. Because *Brachystomum esculentum* are small and light, a suction device is generally used for transfer.
[0003] Traditional insect suction devices have several drawbacks during use. First, they require prolonged suction, which can cause bees to fly out if not handled carefully. Second, it is difficult to control the suction force; excessive suction can cause wheat moth parasitic wasps to remain attached to the mesh for an extended period, affecting the wasps. Third, they can only transfer a small number of wasps, making them time-consuming and laborious.
[0004] Therefore, in view of the shortcomings of the traditional insect suction device mentioned above, a device for artificially collecting large quantities of wheat moth parasitic wasps can be designed. By designing a unique insect storage structure, combined with a manual suction and release mechanism, the wheat moth parasitic wasps cannot escape after entering the insect storage structure, thus solving the above problems. Utility Model Content
[0005] To overcome the shortcomings of traditional insect suction devices, such as easy flight of wasps, excessive suction causing wasps to remain attached to the mesh for a long time, too few wasps to be transferred, and time and labor costs, this utility model provides a device for the artificial collection of large quantities of wasps.
[0006] The technical solution is as follows: A device for manually collecting large quantities of wheat moth parasitic wasps includes an insect storage tube, a suction connector, a flexible tube, an insect suction head, and a replaceable suction nozzle; the front end of the insect storage tube is provided with an insect suction head for sucking in wheat moth parasitic wasps, the inside of the insect storage tube is provided with an insect storage chamber, the rear end of the insect storage tube is provided with a suction connector for creating negative pressure by drawing in air, the rear end of the suction connector is provided with a flexible tube for forming an airflow channel, and the rear end of the flexible tube is provided with a replaceable suction nozzle for easy suction by workers.
[0007] Furthermore, the suction head includes a front-fist type suction mouth, an outward-expanding guide cup at the front of the front-fist type suction mouth, a connector at the front end of the front-fist type suction mouth, a connector fixed to the front end of the front-fist type suction mouth, and an insertion connector corresponding to the connector at the rear end of the outward-expanding guide cup.
[0008] Furthermore, the front end of the insect storage tube is equipped with a connecting joint, and the outer end of the insect storage tube is surrounded by multiple sets of anti-slip strips.
[0009] Furthermore, the rear end of the front bucket-shaped suction nozzle is provided with a rear bucket-shaped escape prevention nozzle, which extends through the connecting joint into the interior of the insect storage chamber. A first limiting ring corresponding to the connecting joint is provided between the front bucket-shaped suction nozzle and the rear bucket-shaped escape prevention nozzle.
[0010] Furthermore, the front end of the suction connector matches and engages with the rear end of the insect storage tube, and a suction port is provided in the center of the suction connector, which is connected to the insect storage chamber.
[0011] Furthermore, the suction port is equipped with a mesh screen inside, and a retaining ring for securing the mesh screen is provided at the rear end of the suction port.
[0012] Furthermore, the rear end of the suction connector is provided with a first insertion tube, the outer end of the connection between the suction connector and the first insertion tube is fitted with a first stop plate, and the rear end of the insect storage tube is fitted with a second stop plate corresponding to the first stop plate.

The ends of the first insertion tube and the second insertion tube that are close to each other are respectively inserted into the two ends of the flexible tube, and a second limiting ring is sleeved on the outer end of the connection between the suction nozzle body and the second insertion tube.
[0014] The beneficial effects are as follows: Compared with the shortcomings of traditional insect aspirators, this application expands the suction range through the outward-expanding guide bucket, enabling the collection of more wheat moth parasitic wasps at once, greatly improving collection efficiency and reducing collection time and labor costs. The rear bucket-shaped escape-proof nozzle design effectively prevents wheat moth parasitic wasps from flying out of the storage chamber, solving the problem of wasps easily flying out in traditional insect aspirators, ensuring the accurate number of wheat moth parasitic wasps collected, and avoiding repeated collection work due to wasps escaping. The negative pressure suction of this device is uniform, preventing wheat moth parasitic wasps from being attached to the mesh for a long time due to excessive suction, reducing damage to the wasps, and helping to protect the activity and health of the wasps, providing a higher quality insect population for subsequent research.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0022] The wheat moth braconid wasp, belonging to the order Hymenoptera, superfamily Ichthyophthidae, and family Braconididae, is distributed globally. It is a gregarious, suppressive ectoparasitic wasp that feeds on oviparous larvae. It is an important natural enemy of lepidopteran larvae in fields and storage facilities. Its hosts include over 40 species of noctuid moths and pyralid moths, such as cotton bollworm, corn borer, rice moth, Mediterranean mealybug, Indian grain moth, large wax moth, and tobacco mealybug. The wheat moth braconid wasp has advantages such as a wide host range, short immaturity period, long adult stage, high reproductive rate, and high paralysis rate. Currently, it is receiving widespread attention as a biological control agent for lepidopteran pests in storage facilities.
[0023] The adult parasitic wasp is tiny, with females measuring about 2.5-3.5 mm in length and males slightly smaller at 2-3 mm. Their bodies are black and glossy. Their antennae are filiform, long, and segmented, approximately the same length as their body, allowing them to keenly perceive environmental information and chemical signals released by the host. They have large, prominent compound eyes and three ocelli arranged in a triangle on their head, providing excellent vision for host location. Their thorax is well-developed, with fine punctures on the mesothorax. Their wings are transparent, with prominent veins on the forewings and smaller hindwings. During flight, the forewings and hindwings work together, enabling the parasitic wasp to move flexibly through space. Their legs are long and slender with five tarsi, allowing them to crawl and grasp surfaces effectively. Their ovipositor is long and slender, hidden at the end of their abdomen, used to inject eggs into the host.
[0024] The life cycle of the wheat moth wasp includes four stages: egg, larva, pupa, and adult. Under suitable temperature conditions of 25-30℃ and humidity of 60%-80%, it usually takes 10-15 days to complete a generation. The egg stage lasts 1-2 days, the larval stage lasts 4-6 days, the pupal stage lasts 4-7 days, and the adult lifespan is generally 10-20 days. If environmental conditions are suitable and food is plentiful, the adult lifespan can be appropriately extended.
[0025] The wheat moth parasitic wasp primarily reproduces sexually. After mating with a male wasp, the female wasp seeks a suitable host to lay her eggs. In the absence of male wasps, some female wasps may also reproduce parthenogenetically, but the offspring produced by parthenogenesis are all male. The female wasp has a strong reproductive capacity; a single female wasp can lay 50-200 eggs in her lifetime, with the specific number of eggs laid depending on environmental conditions, the number and quality of hosts, and other factors.
[0026] After the adults emerge, they need to replenish their nutrition, mainly by feeding on sugary substances such as nectar and honeydew to enhance their physical condition and prolong their lifespan. The larvae, on the other hand, lead a parasitic life. Immediately after hatching, they burrow into the host's body and feed on the host's body fluids and tissues. As the larvae grow and develop, the host gradually weakens until it dies.
[0027] As an important parasitic natural enemy insect, the braconid wasp plays a crucial role in regulating the population size of its host species in nature. By parasitizing the larvae and pupae of its host, it inhibits the normal growth, development, and reproduction of pests, thereby reducing their population density and minimizing their damage to crops and stored grains. Studies have shown that in storage environments with high braconid wasp population densities, the population density of wheat moths and Indian meal borers can be reduced by 70%-80%, effectively protecting the quality and quantity of grains.
[0028] As a member of the ecosystem, the wheat moth parasitic wasp occupies an important position in the food web. Its presence and activities help maintain the biodiversity and stability of the ecosystem. It not only regulates the population of pests, but also provides food resources for other predatory or parasitic natural enemies, promotes the material cycle and energy flow in the ecosystem, and plays an indispensable role in the balance and stability of the ecosystem.
[0029] In agriculture and warehousing, the wheat moth parasitic wasp is a biological control method with great application potential. Compared with chemical control, using wheat moth parasitic wasps for biological control has many advantages. It does not pollute the environment, leaves no harmful residues, and conforms to the concept of green and environmental protection. At the same time, it does not cause pests to develop resistance and can effectively control pest populations in the long term. In the control of stored pests, releasing wheat moth parasitic wasps can reduce the use of chemical agents, reduce the risk of pesticide residues in grains, and ensure food security. In agricultural production, it has also achieved good results in the control of pests such as cotton bollworm, reducing crop losses and improving the quality of agricultural products.
[0030] The wheat moth braconid wasp is also an important model organism for biological research. Its unique parasitic behavior, reproductive methods, and developmental processes provide excellent research subjects for entomology, ecology, genetics, and other disciplines. Studying the wheat moth braconid wasp helps to gain a deeper understanding of biological issues such as insect evolution, parasitic mechanisms, and interspecific relationships, providing theoretical support and practical basis for the development of related disciplines. At the same time, the wheat moth braconid wasp also plays an important role in the research and development of biological control technologies, as well as in the artificial rearing and breeding of natural enemy insects.
[0031] Example
[0032] like Figures 1-5 As shown, an apparatus for the artificial collection of large quantities of wheat moth parasitic wasps includes an insect storage tube 1, a suction connector 2, a flexible tube 4, an insect suction head 3, and a replaceable suction nozzle 5. The front end of the insect storage tube 1 is provided with an insect suction head 3 for sucking in wheat moth parasitic wasps. An insect storage chamber 7 is opened inside the insect storage tube 1. The rear end of the insect storage tube 1 is provided with a suction connector 2 for creating a negative pressure by drawing in air. The rear end of the suction connector 2 is provided with a flexible tube 4 for forming an airflow channel. The rear end of the flexible tube 4 is provided with a replaceable suction nozzle 5 for easy suction by workers.
[0033] The insect suction head 3 includes a front-fist type suction nozzle 301, an outward-expanding guide hopper 305 at the front of the front-fist type suction nozzle 301, a connector 304 at the front end of the front-fist type suction nozzle 301, and a corresponding insertion connector 306 at the rear end of the outward-expanding guide hopper 305. The outward-expanding guide hopper 305 can expand the suction range, allowing more wheat moth parasitic wasps to be guided to the front-fist type suction nozzle 301, thus improving collection efficiency. The cooperation between the connector 304 and the insertion connector 306 facilitates the disassembly and installation of the insect suction head 3, making it convenient for replacement or cleaning.
[0034] The front end of the insect storage tube 1 is provided with a connecting joint 6, and the outer end of the insect storage tube 1 is surrounded by multiple sets of anti-slip strips 8. The anti-slip strips 8 can increase the friction when the staff holds the tube, prevent the insect storage tube 1 from slipping during operation, and improve the stability and safety of operation.
[0035] The rear end of the front bucket-shaped suction nozzle 301 is provided with a rear bucket-shaped escape-proof nozzle 303. The rear bucket-shaped escape-proof nozzle 303 extends through the connecting joint 6 into the interior of the insect storage chamber 7. A first limiting ring 302 corresponding to the connecting joint 6 is provided between the front bucket-shaped suction nozzle 301 and the rear bucket-shaped escape-proof nozzle 303. The rear bucket-shaped escape-proof nozzle 303 can prevent the wheat moth cocoon wasps that have entered the insect storage chamber 7 from flying out in the opposite direction, solving the problem that traditional insect suction devices are prone to causing the wasps to fly out. The first limiting ring 302 can ensure that the insect suction head 3 is installed in an accurate position and ensure that the escape-proof structure functions properly.
[0036] The front end of the suction connector 2 is matched and engaged with the rear end of the insect storage tube 1. The suction connector 2 has a suction port 201 in the center, which is connected to the insect storage chamber 7. The connection between the suction port 201 and the insect storage chamber 7 ensures that the negative pressure suction is evenly transmitted to the insect storage chamber 7 and the suction head 3, effectively sucking up the wheat moth cocoon wasps and ensuring the collection effect.
[0037] The suction port 201 is equipped with a mesh 202 inside. The rear end of the suction port 201 is equipped with a fixing ring 203 for fixing the mesh 202. The mesh 202 can prevent the wheat moth cocoon wasps from being sucked into the hose 4 or even the mouth of the staff, while allowing air to pass through and maintaining negative pressure. The fixing ring 203 can firmly fix the mesh 202 and prevent the mesh 202 from shifting or falling off under the action of negative pressure.
[0038] The suction connector 2 has a first insertion tube 205 at its rear end. The outer end of the suction connector 2 connected to the first insertion tube 205 is fitted with a first stop plate 204. The outer rear end of the insect storage tube 1 is fitted with a second stop plate 9 corresponding to the first stop plate 204. The first stop plate 204 and the second stop plate 9 cooperate with each other to limit the relative position of the suction connector 2 and the insect storage tube 1, preventing the connection from becoming loose due to pulling the hose 4 during use.
[0039] The replaceable suction nozzle 5 includes a nozzle body 501. The rear end of the nozzle body 501 is provided with a second insertion tube 503 corresponding to the first insertion tube 205. The ends of the first insertion tube 205 and the second insertion tube 503 that are close to each other are inserted into the two ends of the hose 4, respectively. A second limiting ring 502 is provided on the outer end of the connection between the nozzle body 501 and the second insertion tube 503. By the second limiting ring 502 being provided on the outer end of the connection between the nozzle body 501 and the second insertion tube 503, the second insertion tube 503 can be prevented from accidentally falling out of the hose 4, thus ensuring the sealing of the airflow channel and the reliability of the device.
[0040] During operation, the worker first inserts the insertion connector 306 of the outward-expanding guide hopper 305 into the connector 304 at the front end of the front hopper-shaped suction nozzle 301, completing the initial assembly of the suction head 3; then, the worker passes the rear hopper-shaped escape-proof nozzle 303 through the connector 6 at the front end of the insect storage tube 1, so that the first limiting ring 302 engages with the connector 6, ensuring that the suction head 3 is installed in place; the worker then matches and engages the front end of the suction connector 2 with the rear end of the insect storage tube 1, so that the first stop plate 204 and the second stop plate 9 engage with each other, limiting their relative positions; finally, the worker places both ends of the flexible hose 4 onto the first insertion tube 205 at the rear end of the suction connector 2 and the second insertion tube 503 of the replaceable suction nozzle 5, and places the second limiting ring 502 on the outer end of the connection between the nozzle body 501 and the second insertion tube 503, completing the assembly of the entire device.
[0041] Then, the staff holds the insect storage tube 1 and uses the outward-expanding guide bucket 305 to cover the activity area of the wheat moth parasitic wasp. They then manually suck it in through the replaceable suction nozzle 5. After the wheat moth parasitic wasp is sucked into the front bucket-shaped suction nozzle 301, it enters the insect storage chamber 7 through the rear bucket-shaped escape prevention nozzle 303 under negative pressure. After collection, the replaceable suction nozzle 5, hose 4, suction connector 2, and insect suction head 3 are disassembled in sequence and each part is cleaned for future use.
[0042] Its working principle is as follows: when researchers use the replaceable suction nozzle 5 to suction, air enters from the outward-expanding guide hopper 305 and the front-flush type suction nozzle 301, creating negative pressure within the insect storage tube 1, the flexible tube 4, and the suction connector 2. Since the suction port 201 is connected to the insect storage chamber 7, the negative pressure suction is evenly transmitted to the insect storage chamber 7 and the suction head 3. The outward-expanding guide hopper 305 expands the suction range, guiding more wasps to the front-flush type suction nozzle 301. Under the action of negative pressure, the wasps pass through the front-flush type suction nozzle 301 and enter the insect storage chamber 7 through the rear-flush type escape-prevention nozzle 303. The mesh 202 inside the suction port 201 prevents wasps from being sucked into the flexible tube 4 or even the staff's mouth, while allowing air to pass through and maintaining the negative pressure state. The retaining ring 203 securely fixes the mesh 202 to prevent it from shifting or falling off. The first stop plate 204, the second stop plate 9, the second limit ring 502, and other structures ensure stable connection of each component, guarantee the airtightness of the airflow channel and the normal operation of the device.
[0043] Its beneficial effects are significant. The outward-expanding guide bucket 305 expands the suction range, enabling the collection of more wheat moth parasitic wasps at once compared to traditional insect aspirators, greatly improving collection efficiency and reducing collection time and labor costs. The rear bucket-shaped escape-proof nozzle 303 effectively prevents wheat moth parasitic wasps entering the insect storage chamber 7 from flying out in the opposite direction, solving the problem of wasps easily flying out in traditional insect aspirators, ensuring the accurate number of wheat moth parasitic wasps collected, and avoiding repeated collection work caused by wasps escaping. The negative pressure suction of this device is uniform, and there will be no situation where the wheat moth parasitic wasps are attached to the mesh 202 for a long time due to excessive suction, reducing damage to the wheat moth parasitic wasps and helping to protect the activity and health of the wheat moth parasitic wasps, providing a better test insect population for subsequent research. The anti-slip strip 8 on the outer end of the insect storage tube 1 increases the friction when the operator holds it, preventing the insect storage tube 1 from slipping during operation. At the same time, the suction head 3 is easy to disassemble and install, and convenient to replace or clean, improving the practicality and durability of the device.
