Description

Technical Field

[0001] This invention belongs to the technical field of insect rearing and egg collection, specifically relating to a device for rearing and collecting eggs of adult lacewing natural enemy insects and its usage method. Background Technology

[0002] Natural enemy insects are insects that feed on other insects. They typically survive by preying on or parasitizing other insects, thus controlling pest populations. Natural enemy insects include ladybugs, mantises, assassin bugs, and parasitic wasps, playing crucial roles in ecosystems and helping to maintain ecological balance. In agricultural production, natural enemy insects are also widely used in biological control techniques to reduce reliance on chemical pesticides and protect crops from pests.

[0003] Lacewings are highly valuable natural enemies in ecological agriculture and biological control, used to control various agricultural pests such as aphids, mites, thrips, whiteflies, and scale insects. However, large-scale rearing and efficient egg collection of these natural enemies present significant challenges with existing technologies. These challenges include inadequate design of adult rearing spaces, low efficiency in oviposition induction, and cumbersome and inefficient egg collection processes. Traditional methods, especially in improving egg collection efficiency and handling, often fail to meet the demands of large-scale production. Therefore, it is necessary to develop a novel device for rearing and collecting eggs from adult lacewings to improve automation and ensure efficient reproduction. Summary of the Invention

[0004] To address the shortcomings of existing technologies and fully utilize the role of lacewing natural enemy insects in pest control, this invention provides a device for rearing and collecting eggs from adult lacewing natural enemy insects, along with its method of use. This device integrates multiple structural components to regulate key environmental factors during the rearing and egg-laying process of adult lacewing natural enemy insects, including humidity, light, and wind speed. This creates a suitable environment for egg-laying, promotes egg production, simplifies the egg-collecting process, and improves the efficiency of egg collection.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A device for rearing and collecting eggs from adult lacewing natural enemy insects includes an ovipositor structure, an ovipositor lifting structure, a lighting device, an isolation plate, an egg collection device, and an outer casing. The outer casing contains a rearing chamber for the adult lacewing natural enemy insects, with an opening at the lower end. The isolation plate is installed at the lower part of the outer casing and closes the lower opening of the rearing chamber. Several perforations are formed on the isolation plate. The ovipositor lifting structure is installed on the outer casing. The egg collection device includes a liquid container and a filter screen. The liquid container is located below the isolation plate and can hold water or a solution. The net can be installed in a liquid container. The ovipositor structure includes several ovipositors, each with absorbent material fixed at intervals. The upper part of the ovipositor is located inside the rearing chamber of the adult lacewing predator and is connected to the ovipositor lifting structure. The lower end of the ovipositor passes through a perforation and extends to below the partition plate. The ovipositor lifting structure can move the ovipositor up and down. When the ovipositor moves down, the absorbent material on the ovipositor can extend into the liquid container to absorb water. When the ovipositor moves up, the absorbent material on the ovipositor passes through the perforation and enters the rearing chamber of the adult lacewing predator. The lighting device is connected to the ovipositor and is used to make the ovipositor emit light.

[0007] To optimize the above technical solution, the specific measures also include:

[0008] The upper end of the aforementioned spawning column is fixed to the mounting plate. The spawning column consists of two parts: the upper quarter is an opaque hollow part, and the lower three-quarters is a transparent part. The lighting device includes LED beads, which are installed in the opaque hollow part. The light from the LED beads can enter the transparent part, causing the transparent part of the spawning column to emit light. The LED beads are connected to a lamp bead control module, which is used to control the color, brightness, and illumination mode of the LED beads.

[0009] The aforementioned absorbent material is black absorbent non-woven fabric, and the oviposition column is an acrylic column. The absorbent material is placed in the transparent part of the oviposition column.

[0010] The aforementioned egg-laying column lifting structure includes a lifting cylinder and a cylinder controller. Both the lifting cylinder and the cylinder controller are fixed on the equipment housing. The drive shaft of the lifting cylinder is fixedly connected to the mounting plate, and the cylinder controller is used to control the movement of the lifting cylinder.

[0011] A cleaning groove is provided in the middle of the upper surface of the aforementioned isolation plate. One end of the cleaning groove opens to the side of the equipment casing. A pull-out feed tray is installed on the cleaning groove, and feed for raising adult lacewing natural enemy insects is placed on the feed tray.

[0012] The aforementioned equipment has fans installed on both sides of its outer casing. The fans are used to ventilate the rearing chamber of adult lacewing insects. The fans are connected to a fan control module, which controls the fan speed. When the feed tray is pulled out of the cleaning trough, the fan has enough airflow to blow the dead lacewing insects that have fallen onto the isolation plate into the cleaning trough.

[0013] The aforementioned equipment housing is equipped with a sliding rail at the bottom, with one end of the sliding rail located directly below the isolation plate, and the liquid container is slidably mounted on the sliding rail.

[0014] The aforementioned equipment casing is equipped with a vibrator, which is connected to the oviposition column. The vibrator is also connected to a vibrator control module, which is used to control the vibration amplitude of the vibrator and to generate vibration on the oviposition column. The equipment casing has an adult insect collection hole that connects to the rearing chamber of adult lacewing natural enemy insects, and the adult insect collection hole is covered with an openable and closable cap.

[0015] The walls of the rearing chambers of the aforementioned lacewing natural enemy insects were coated with petroleum jelly.

[0016] The method for using a device for rearing and collecting eggs of adult lacewing natural enemy insects includes the following steps:

[0017] Step 1: Fill a liquid container with clean water and place it under the isolation plate;

[0018] Step 2: Activate the spawning column lifting mechanism to move the spawning column downwards, allowing the main body of the spawning column to descend into the liquid container and fully absorb the water-absorbing material;

[0019] Step 3: The oviposition column lifting structure moves the oviposition column upwards so that the main body of the oviposition column is located inside the rearing chamber of the lacewing natural enemy insects. The lower end of the oviposition column remains in the state of passing through the perforation. The lacewing natural enemy insects are placed into the rearing chamber through the adult collection hole, and feed is placed on the feed tray.

[0020] Step 4: Activate the lighting device to make the transparent part of the ovipositor glow, attracting adult lacewing predators to lay their eggs on the absorbent material of the ovipositor;

[0021] Step 5: Replace the water in the liquid container with sodium hypochlorite solution, install a filter screen in the liquid container, activate the oviposition column lifting mechanism to move the oviposition column downwards, so that the main body of the oviposition column is lowered into the liquid container, the absorbent material is immersed in the sodium hypochlorite solution, the sodium hypochlorite solution dissolves the egg stalks of the lacewing predator insects, the vibrator drives the oviposition column to vibrate, causing the lacewing predator insect eggs to fall off the absorbent material and fall into the filter screen;

[0022] Step Six: Using the oviposition column lifting mechanism, move the oviposition column upwards, remove the filter screen from the liquid container, rinse the eggs in the filter screen with clean water, and dry them with a hair dryer to obtain the eggs of the lacewing family natural enemy insects.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention features a unique oviposition column design. This design combines an opaque, hollow upper section housing LED beads with a transparent acrylic lower section to create a suitable lighting environment that induces adult lacewing predators to lay eggs. The lighting conditions are adjustable; the color and pattern of the light can be adjusted according to the different growth and reproduction stages of the lacewing predators, meeting their needs at different life stages. Simultaneously, the absorbent black non-woven fabric of the oviposition column maintains suitable humidity, providing an ideal oviposition site for the lacewing predators.

[0025] 2. This invention boasts a high degree of automation, evident in its controllable lifting system. This automates the processes of adjusting the position of the ovipositor and its entry into the water storage container for increased humidity (ovipositor humidification function), or its entry into the sodium hypochlorite solution for egg collection (egg collection function), thereby reducing the need for manual operation. Furthermore, the vibrator design ensures that the absorbent black non-woven fabric of the ovipositor fully absorbs moisture (ovipositor humidification function) or improves the efficiency of dissolving the ovipositor stalk in the sodium hypochlorite solution (egg collection function). This not only promotes uniform moisture distribution, full absorption, and efficient egg collection, but the slight vibration of the ovipositor also stimulates the lacewing predators, increasing their oviposition capacity.

[0026] 3. This invention also includes a fan assembly with adjustable wind speed and start-up time. This provides fresh air for the lacewing predators, promotes egg-laying by simulating natural wind, and cleans the interior of the device, maintaining a hygienic rearing environment. The pull-out feeding tray at the bottom of the partition plate allows for easy addition and replacement of feed. Furthermore, after the feeding tray is removed, a cleaning groove is exposed at the bottom of the rearing device, facilitating the removal of lacewing predator carcasses from the device using the fans on both sides. This ensures a clean environment for the lacewing predators' growth and reproduction, preventing adverse environmental conditions from affecting their survival and reproductive quality.

[0027] 4. The design of the sliding track and egg collection section of this invention makes egg collection more convenient and efficient. The sliding track allows the entire device to move easily after egg collection, while the egg collection section uses a combination of a water tank and a filter screen, along with sodium hypochlorite solution, to efficiently separate the eggs, keeping them intact and clean.

[0028] 5. To prevent lacewing predators from laying eggs in non-target areas, the inner wall is coated with petroleum jelly. This simple and effective strategy significantly improves the concentration of egg laying and reduces egg loss during collection.

[0029] In summary, this invention, by integrating multiple functions and automation technologies, significantly improves the efficiency of raising and collecting eggs from adult lacewing natural enemy insects, reduces labor costs, and also increases the safety and convenience of egg collection and processing. This is of great significance for promoting the commercialization and large-scale production of biological control technologies. Attached Figure Description

[0042] like Figure 1-7As shown, the present invention has an oviposition column structure 1, an oviposition column lifting structure 2, a lighting device 3, an isolation plate 4, an egg recovery device 5, an equipment shell 6, a fan structure, a vibrator 9, and other structures.

[0043] The oviposition column structure 1 includes an oviposition column 11 and a mounting plate 12. The mounting plate 12 is a flat plate used to fix the oviposition column 11. The oviposition column 11 consists of two parts: the upper quarter is an opaque hollow part with LED beads 31 installed in the upper hollow part; the lower three-quarters is an intermittent transparent part, which is composed of absorbent black non-woven fabric 13 and a transparent acrylic column. This design can provide light through the LED beads in the upper opaque hollow part, and light will shine out from the lower transparent acrylic part. The light can be adjusted according to the preferences of the lacewing predator insects, including color, brightness, and illumination mode. The light in the transparent part of the oviposition column 11 can attract lacewing predator insects to lay eggs on the oviposition column 11.

[0044] Before releasing the lacewing predators, the ovipositor 11 is lowered via a remote-controlled lifting device through a perforated partition plate 4. The perforations 41 on the partition plate 4 correspond one-to-one with the ovipositor 11, and their diameters are identical, ensuring the ovipositor 11 can move up and down. Furthermore, when the ovipositor 11 reaches its highest point, its lowest part is within the perforations 41, preventing adult lacewing predators from passing through. The ovipositor 11 escapes through the hole and is immersed in a pre-filled water container via a lifting device. The absorbent portion of the ovipositor 11 absorbs sufficient water. To ensure adequate absorption, a vibrator 9 located below the fixing plate of the ovipositor 11 is activated. This vibrator 9 adjusts the vibration frequency of the ovipositor 11, ensuring the absorbent portion is fully saturated. There are two reasons for this: 1. Adult lacewing predators need to ingest water for growth; 2. Lacewing predators prefer to lay their eggs in humid environments. This ensures that the lacewing predators lay the majority of their eggs on absorbent material, facilitating egg collection and improving collection efficiency.

[0045] There are two sets of fans 7 on the left and right sides of the device casing 6. The fans can adjust the wind speed and set the start time. The fans have the following functions: 1. Ventilate the growth environment of the lacewing natural enemy insects and improve their living environment; 2. Simulate natural wind to give the lacewings a slight stimulation and encourage them to lay eggs; 3. Cleaning function: when adult insects die naturally, the feed tray 43 in the middle of the device can be pulled out. After pulling it out, there will be a rectangular hollow in the middle of the device's isolation plate 4, which is the cleaning groove 42. By adjusting the wind speed of the fans on the left and right sides of the device, the dead bodies of the lacewing natural enemy insects can be blown out of the device, ensuring the cleanliness of the breeding environment and enabling the lacewing natural enemy insects to grow healthily.

[0046] The feeding tray 43 for lacewing natural enemy insects is located at the bottom of the device, in the middle of the partition plate 4. There is a rectangular cleaning trough 42. The feeding tray 43 for lacewing natural enemy insects can be freely pulled out. When feeding, the feeding tray 43 for lacewing natural enemy insects is pulled out, artificial feed is put in, and then the feeding tray 43 for lacewing natural enemy insects is inserted into the cleaning trough 42.

[0047] The device of the present invention is placed on a sliding track 8, which allows the device to slide left and right. After the egg collection is completed, the egg recovery device 5 is moved to one side along the sliding track 8 to facilitate the removal of the filter screen 52 for the next step of egg cleaning, drying and packaging.

[0048] Egg collection section: This section consists of a liquid container 51 and a 60-mesh filter screen inside the liquid container 51. This section ensures that the lower three-quarters of the ovipositor 11 is completely immersed in the liquid during its raising and lowering process. The liquid in the liquid container 51 is a sodium hypochlorite solution with a volume ratio of 20%. During operation, the ovipositor 11 is lowered by the lifting device, allowing it to be immersed in the sodium hypochlorite solution. To accelerate the dissolution of the egg stalks of the lacewing predator insects by sodium hypochlorite, at this time... Activate the vibrator 9 at the bottom of the fixing plate of the ovipositor 11 to make the ovipositor 11 vibrate at a suitable frequency, which accelerates the dissolution of the egg stalks of the lacewing natural enemy insects. After the egg stalks dissolve, the eggs will fall into the filter screen 52. After the egg collection is completed, raise the ovipositor 11 to the highest point, and then move the device to the side via the slide rail. Then take out the filter screen 52 in the sodium hypochlorite. All the eggs are collected in the filter screen 52. Then rinse the eggs in the filter screen 52 with clean water and dry them with a hair dryer. Finally, collect the eggs and package the product.

[0049] To ensure that the lacewing predators lay most of their eggs on the oviposition column 11, petroleum jelly was applied to the inner wall of the device, making it difficult for the lacewing predators to lay their eggs on the inner wall of the device.

[0050] The method of using the device for rearing and collecting eggs of adult lacewing natural enemy insects of the present invention includes the following steps:

[0051] Step 1: Fill the liquid container 51 with clean water and place it below the isolation plate 4. Put the adult lacewings into the rearing chamber through the adult collection hole 61 and place the feed on the feed tray 43.

[0052] Step 2: Activate the spawning column lifting structure 2 to move the spawning column 11 downwards, so that the main body of the spawning column 11 is lowered into the liquid container 51, and the absorbent material is fully absorbed by the liquid.

[0053] Step 3: The oviposition column lifting structure 2 moves the oviposition column 11 upward so that the main body of the oviposition column 11 is located in the rearing chamber of the adult lacewing natural enemy insect, while the lower end of the oviposition column 11 remains in the state of passing through the perforation 41.

[0054] Step 4: Activate the lighting device 3 to make the transparent part of the ovipositor 11 glow, attracting adult lacewing insects to lay their eggs on the absorbent material of the ovipositor 11;

[0055] Step 5: Replace the clean water in liquid container 51 with a sodium hypochlorite solution with a volume ratio of 20%. Install filter screen 52 in liquid container 51. Activate oviposition column lifting structure 2 to move oviposition column 11 downwards, so that the main body of oviposition column 11 is lowered into liquid container 51. Immerse the absorbent material in sodium hypochlorite solution. Sodium hypochlorite solution dissolves the egg stalks of lacewing predator insects. Vibrator 9 drives oviposition column 11 to vibrate, causing the lacewing predator insect eggs to fall off the absorbent material and into filter screen 52.

[0056] Step 6: The egg-laying column lifting structure 2 moves the egg-laying column 11 upward, removes the filter screen 52 from the liquid container 51, rinses the eggs in the filter screen 52 with clean water, dries them with a hair dryer, and finally collects the eggs and packages the product.

[0057] The above are preferred embodiments of this application. However, those skilled in the art, once they understand the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0058] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
