Description

Technical Field

[0001] This utility model relates to the field of parasitic wasp breeding technology, and more specifically, to a device for the collective breeding and release of parasitic wasps. Background Technology

[0002] Parasitic wasps are a special type of wasp whose lifestyle primarily relies on laying their eggs inside or on the bodies of other insects. The hatched larvae then feed on the host, ultimately leading to the host's death. Parasitic wasps are important natural enemies of insects, playing an irreplaceable role in maintaining ecological balance and controlling pests in agricultural production. Through scientific management and rational utilization, parasitic wasps can contribute to reducing the use of chemical pesticides, protecting the environment, and improving the quality of agricultural products. The feeding efficiency of parasitic wasps directly affects the development of female eggs, thus influencing their lifespan, ultimate fertility, and pest control ability. Furthermore, the artificial breeding of parasitic wasps often consumes significant human and material resources, and the use of smaller parasitic wasps further increases costs.

[0003] Currently, most parasitic wasp products are made from wasp cocoons (pupa stage), with fewer adult wasp products. When pests occur on a large scale in the field, the pests and parasitic wasps often do not move in sync, making it impossible to achieve pest control. Furthermore, the mortality rate of adult parasitic wasps is too high during transportation, resulting in low product yields and increased usage costs.

[0004] In conclusion, to improve pest control effectiveness, it is necessary to address the shortage of adult bee products, integrate parasitic wasp rearing and transportation / release, improve parasitic wasp survival rate, and thus increase the number of parasitic wasps. Utility Model Content

[0005] The problem to be solved by the parasitic wasp collective rearing and release device provided by this utility model is that parasitic wasp products are mainly bee cocoons, and at the same time, the high mortality rate of adult parasitic wasps during transportation results in a small number of adult wasp products.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a parasitic wasp collective rearing and release device, comprising an outer tube, a first ventilation hole on the outer side of the outer tube, a storage tube for storing and rearing parasitic wasps fixedly connected to the inner side of the outer tube, a connecting hole at the lower end of the storage tube, a second ventilation hole on the outer side of the storage tube, a threaded tube fixedly connected to the upper ends of the outer tube and the storage tube, a sealing cap threadedly connected to the outer side of the threaded tube, an installation platform fixedly connected to the upper end of the sealing cap, rotating seats fixedly connected to both the front and rear ends of the sealing cap, a suspension rod rotatably connected to the outer side of the rotating seat, a rotating cover plate rotatably connected to the outer side of the installation platform, a guide platform fixedly connected to the lower end of the installation platform, a climbing hole for releasing parasitic wasps on the inner side of the installation platform, and a honey strip provided on the inner side of the guide platform.

[0007] In a preferred embodiment, a support platform is provided at the lower end of the outer sleeve, and a positioning frame is fixed to the outside of the support platform.

[0008] In a preferred embodiment, a mounting block is fixed to the inner side of the support platform, and a placement plate is fixed to the support platform.

[0009] In a preferred embodiment, a storage box is provided at the upper end of the mounting block, and a positioning hole is provided on the inner side of the storage box, which is slidably connected to the outer sleeve.

[0010] In a preferred embodiment, the upper end of the storage box is provided with a cover body, and the upper end of the cover body is equipped with a lifting lug.

[0011] In a preferred embodiment, a hook is rotatably connected to the lower end of the cover body, and a rotating frame is rotatably connected to the outer side of the cover body.

[0012] In a preferred embodiment, the lower end of the support platform is provided with a base body, the inner side of the base body is provided with a communication port, and the upper end of the communication port is rotatably connected with a baffle plate.

[0013] In a preferred embodiment, an air pump body is mounted on the outside of the base body, and a filter plate body is fixedly connected to the input end of the air pump body. The air pump body is used to supply air to the connection port.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention uses a storage tube to store parasitic wasps, a threaded tube with a sealing cap, and a sealing film to seal the opening. Honey strips are placed inside the guide platform to feed the parasitic wasps, ensuring their survival. The guide platform, along with climbing holes, facilitates the parasitic wasps' climbing, and the corresponding rotating cover is opened to release them. This increases the success rate of parasitic wasp rearing, ensures the number of adult wasps, and improves the effectiveness of pest control.

[0016] This utility model uses a suspension rod and hook to suspend and support the outer tube, making it convenient to store and use. The cover body is moved by the lifting lugs, so as to cooperate with the storage box to store the outer tube. The air pump body and the filter plate body are used as the connection port to supply air, and the baffle plate is used to block part of the airflow entering the support platform and storage box, thereby maintaining a certain environment and further improving the survival rate.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Existing technologies have been discovered that parasitic wasps are a type of wasp in the order Hymenoptera that have parasitic habits. They lay their eggs inside or on the body of other insects or arthropods. After hatching, the larvae feed on the host to complete their development, ultimately causing the host's death. These wasps play an important role in the ecosystem and are often used for the biological control of agricultural pests.

[0026] I. Main Features

[0027] 1. Parasitic habits: The larvae depend on the host (such as lepidopteran larvae, aphids, spider egg sacs, etc.) for survival, while the adult bees live freely.

[0028] 2. Variety in size: Body length ranges from less than 1 millimeter to several centimeters, with most being relatively small.

[0029] 3. Specialized ovipositor: The ovipositor of the female wasp is often specialized into a needle-like shape, used to pierce the host or plant tissue.

[0030] II. Common Categories:

[0031] Ichneumonidae: Parasitizes holometabolous insects (such as bollworms, diamondback moths, and beet armyworms) of the orders Lepidoptera, Coleoptera, and Diptera, and never parasitizes insects with incomplete metamorphosis.

[0032] Braconidae: Their hosts are all insects, with the most widespread being holometabolous insects, and the vast majority of them are Lepidoptera. In contrast, the subfamily Braconidae are all parasitic on Hemiptera, specifically the Aphididae family, such as the tobacco aphid wasp.

[0033] Pteromal idae: The vast majority are parasitic, with very few being herbivorous, such as the pupa of the fly that parasitizes the pupae of the black-bellied fruit fly.

[0034] Encyrtidae: Most species parasitize scale insects, but some can also parasitize mites, ticks, and spiders.

[0035] Trichogrammatidae: Widely used for the biological control of various pests, especially lepidopteran pests, such as the corn borer.

[0036] Three: Parasitic strategies:

[0037] 1. Endoparasitism: The eggs are laid inside the host, and the larvae feed inside.

[0038] 2. Ectoplasmosis: Eggs are laid on the surface of the host, and the larvae feed on the outside.

[0039] 3. Tolerant parasitism: The host survives initially but eventually dies.

[0040] 4. Suppressive parasitism: During the oviposition process, venom is injected into the host, causing the host to die, be permanently anesthetized, or stop developing.

[0041] IV. Ecological and Economic Significance:

[0042] 1. Biological control: use natural enemy insects to reduce pesticide use (e.g., use Trichogramma wasps to control corn borers).

[0043] 2. Ecological balance: Controlling pest populations and maintaining biodiversity.

[0044] 3. Research models: used for behavioral and evolutionary biology research (such as host-parasite co-evolution).

[0045] Five: Interesting Phenomena

[0046] 1. Parasitism: a state between parasitism and predation, which will kill the host.

[0047] 2. Polyembryony: One egg can divide into multiple individuals (such as some small wasps).

[0048] 3. Host manipulation: Some parasitic wasp larvae can alter the behavior of their hosts.

[0049] The complex relationship between parasitic wasps and their hosts is a classic example of co-evolution in nature and an important tool for integrated pest management (IPM) in agriculture.

[0050] Currently available technologies have been discovered that the biological control of parasitic wasps first requires the rearing of parasitic wasps.

[0051] I. Core Conditions for Breeding

[0052] 1. Environmental control

[0053] Temperature and humidity: Most parasitic wasps require a constant temperature and humidity environment (such as 25℃, 70-80% relative humidity) and 14 hours of light to ensure development rate and parasitism efficiency.

[0054] Device design: The dedicated feeding and release device should include a moisture-retaining layer, an eclosion tube, and a nutrient replenishment tank to ensure that the parasitic wasps get sufficient rest and nutrition after eclosion.

[0055] 2. Host selection

[0056] The target parasitic wasp species needs to be matched, for example:

[0057] Trichogramma wasps: use the eggs of lepidopteran pests as hosts (such as corn borers);

[0058] Leafminer wasp: Using leafminer larvae as hosts, it improves reproductive efficiency through parthenogenesis strains;

[0059] Oriental fruit fly whip wasp: Housefly pupae need to be cultured as hosts.

[0060] Currently available technologies have been identified for the implementation of biological control using parasitic wasps, which requires the introduction of parasitic wasps into the control area.

[0061] I. Innovation in Intelligent Release Equipment

[0062] Precise drone spraying: Equipped with a GPS positioning system, it releases special bee balls (each ball contains 500 Zhou's parasitic wasps), with a positioning accuracy of ±0.5 meters, and can cover an average of 1,500 mu of cornfields per day.

[0063] Traditional carrier optimization: When controlling the fall webworm, parasitize the silkworm pupa with the parasitoid wasp Zhou's worm (each pupa contains 5,000 parasites) and hang it 2 meters high on the tree trunk; in Hainan areca nut plantations, bee release devices are used, containing stiff pupae containing the parasitoid wasp Zhou's worm.

[0064] II. Standardized Operating Procedures

[0065] 1. Key release parameters

[0066] Trichogramma wasps in cornfields: Hang 20 egg cards per acre (parasitism rate ≥80%) at a height of 1.2-1.5 meters (at an adult's chest level), close to the main vein on the underside of the leaves.

[0067] Greenhouse Encarsia formosa: Release at a density of 5 individuals / ㎡, with a 7-day interval for 4 consecutive weeks, avoiding high-temperature periods.

[0068] Rice paddy Trichogramma wasps: 0.9 million wasps per mu (0.067 hectares) per single release, twice with a 3-day interval, increasing the efficiency of drone-based wasp ball distribution by 40%.

[0069] 2. Operating Precautions

[0070] Weather response: Light rain is acceptable for normal operation. In case of heavy rain, temporarily store the beehives in a cool place (lay them flat and do not stack them). Complete the deployment within 2 hours after the rain stops.

[0071] Pesticide isolation: Do not apply chemical pesticides for 7 days before and after release to avoid bee colony deaths.

[0072] Storage and transportation requirements: Refrigerate at 0-5℃ throughout the transportation process, and avoid direct sunlight in the field (broad leaves can be used for shading to retain moisture).

[0073] III. Typical Cases of Regional Application

[0074] Forest control in Beijing: 600,000 *Sclerodermus guani* wasps were released, which are obligate parasites of the larvae of the *Cephalotaxus fortunei*, reducing trunk borer damage by 85%.

[0075] In Hainan's areca nut plantation management, a combined release of Coconut Flat Beetle and Vein-Cut Wasp (2,220 wasps / mu) was used, with a total scale of 8.88 million wasps, achieving a pest control rate of over 90%.

[0076] In Liaoning's cornfields, drones are used to spray Trichogramma wasp egg cards, reducing chemical pesticide use by over 60% and increasing yield by 8%-20%.

[0077] IV. Technological Innovation Directions

[0078] Selection of stress-resistant strains: The parasitism efficiency of the heat-resistant Trichogramma wasp (development threshold temperature 13.6℃) remains at 72% in an environment of 35℃; the tolerance concentration of the imidacloprid-resistant parasitic wasp is increased by 8 times.

[0079] Ecological Collaboration Strategy: Shanghai's Changning District has accurately deployed parasitic wasps through the "Cicada Song Map" citizen data platform, resulting in a 62% decrease in cicada-related complaints.

[0080] Economic benefits: The cost of pest control per acre has been reduced to one-third of that of chemical pesticides. Beijing produces 300 billion parasitic wasps annually, resulting in a cumulative reduction of 320 million yuan in plant protection expenditures. In the future, combining drone-based wasp spheres with gene editing (regulating odor receptors) will enhance ecological compatibility.

[0097] Working principle: First, parasitic wasps are stored in the storage tube 3, and a sealing cap 7 is installed using the threaded tube 6 and sealed with a sealing film. Next, the smaller diameter of the second ventilation hole 5 is used for ventilation while preventing the parasitic wasps from escaping.
