Description

Technical Field

[0001] This utility model relates to the field of pest control technology, and in particular to a parasitic wasp parasitism efficiency monitor. Background Technology

[0002] With the iterative upgrading of modern warehousing technology systems, integrated pest management has become a core issue in ensuring the storage quality of high-value-added agricultural products. For strategic economic crops like tobacco, the construction of pest control systems in the storage process is particularly important. While the current mainstream chemical fumigation method possesses rapid insecticidal properties, long-term application has shown that it has a dual negative effect: on the one hand, the bioaccumulation of organophosphate pesticides in the environment leads to ecological chain pollution; on the other hand, the metabolic resistance mechanisms of target pests are rapidly formed, resulting in diminishing marginal returns to control efficacy. Against this backdrop, ecological regulation strategies based on the principle of biointeraction—including green control methods such as the release of natural enemy insects, pheromone interference, and microbial antagonism—are gradually becoming a technological innovation direction in the field of stored-store pest management due to their environmentally friendly characteristics and sustainable pest control advantages.

[0003] Patent CN110150233A proposes a biological control technology based on the wheat moth parasitoid wasp. This technology achieves large-scale breeding through a nutrient substrate of bee sugar water. It utilizes the parasitic characteristics of the wheat moth parasitoid wasp, allowing it to complete the development process of egg, larva, and pupa within the host larva. Finally, the adult wasps, which have undergone low-temperature dormancy treatment, are released into the tobacco storage environment. The wasps achieve targeted killing of tobacco mealybug larvae through their parasitic effect on the larvae.

[0004] Currently, there are many mature methods for the rearing and release of *Condor heptaphyllum*, but the parasitism efficiency and monitoring of the parasitism process still rely on manual observation and statistical calculations. This method is not only time-consuming and labor-intensive, but also limited by the frequency of observation, making timely data acquisition impossible. This leads to data bias and hinders the improvement of subsequent *Condor heptaphyllum* release techniques. Therefore, developing a device for monitoring the parasitism process of *Condor heptaphyllum* is an urgent problem to be solved. Utility Model Content

Figure 3 This schematic diagram illustrates the structure of an observation device according to one embodiment of the present invention, as shown below. Figure 1-3 As shown, the parasitic wasp parasitism efficiency monitor of this utility model includes:

[0036] Parasitic wasp rearing device 10 and observation device 20;

[0037] The parasitic wasp rearing device 10 is used to rear parasitic wasps. The parasitic wasp rearing device 10 has an openable and closable first opening 101 on its side wall for parasitic wasps to pass through.

[0038] An observation device 20 is set around the parasitic wasp rearing device 10. The surface of the observation device 20 is provided with a mesh 201 for the parasitic wasps to pass through. The host larvae are placed inside the observation device 20. A first monitor 202 is set on the top of the observation device 20.

[0039] Specifically, the parasitic wasp rearing device 10 is used for the cultivation of parasitic wasps. After the parasitic wasps reproduce the second generation of parasitic wasp larvae in the parasitic wasp rearing device 10, an observation device 20 containing host larvae is placed around the parasitic wasp rearing device 10, with a distance of 10m between them. Multiple observation devices 20 can be set up and arranged circumferentially with the parasitic wasp rearing device 10 as the center. The ratio of the number of host larvae to the number of pairs of parasitic wasps is 10:1.

[0040] Based on this, due to the parasitic characteristics of parasitic wasps, the second generation of parasitic wasps flew out of the parasitic wasp rearing device 10, passed through the mesh 201 and flew into the observation device 20 to parasitize the host larvae and achieve reproduction.

[0041] Meanwhile, a first monitor 202 is installed inside the observation device 20. The first monitor 202 is an infrared camera located on the top of the observation device 20. It can monitor the internal situation of the observation device 20 in real time and can be set to take pictures of the inside of the observation device 20 at regular intervals. The first monitor 202 is also connected to an external control system to send the captured images to the external control system for calculation of the parasitic wasp parasitism situation.

[0042] This setup solves the problems of time-consuming, labor-intensive, and error-prone manual observation and statistical methods in traditional technologies. The data obtained by this device is accurate and can provide effective data support for subsequent optimization of parasitic wasp deployment density and formulation of targeted biological control strategies for pests.

[0043] Furthermore, the parasitic wasp rearing device 10 includes a box 102, a food storage chamber 103, a rearing chamber 104, and a second monitor 105 disposed within the box 102;

[0044] The first opening 101 is located on the side wall of the box 102. A second opening 106 is also located on the side wall of the box 102. The food storage chamber 103 is connected to the second opening 106. The second opening 106 is used for supplementing food. The feeding chamber 104 is located around the food storage chamber 103. The food storage chamber 103 and the feeding chamber 104 are connected. The second monitor 105 is installed on the inner wall of the box 102. The feeding chamber 104 is used to feed parasitic wasps. The second monitor 105 is used to observe the activity of parasitic wasps inside the box 102.

[0045] Specifically, an installation platform 1021 is provided inside the box 102, and the food storage chamber 103 and the feeding chamber 104 are fixed to the bottom of the installation platform 1021, with the food storage chamber 103 and the feeding chamber 104 exposed above the installation platform 1021.

[0046] The second monitor 105 and the first opening 101 are located above the mounting platform 1021, and the second opening 106 is located below the mounting platform 1021. The second monitor 105 can be configured as an infrared camera.

[0047] At least one feeding chamber 104 is provided. In this utility model, three feeding chambers 104 are provided. The three feeding chambers 104 and one food storage chamber 103 are respectively distributed in the four corners of the box body 102. The food storage chamber 103 is connected to the second opening 106. The food storage chamber 103 stores honey water. Honey water with a concentration of 10-70% can be added to the food storage chamber 103 daily through the second opening 106 for the parasitic bees to eat.

[0048] When raising parasitic wasps, host larvae are placed in the rearing chamber 104, and pairs of first-generation adult parasitic wasps are introduced. The rearing status of the parasitic wasps in the rearing chamber 104 is observed through the second monitor 105, and the first-generation parasitic wasps lay eggs to produce second-generation parasitic wasps.

[0049] After the second generation of parasitic wasps appear, the parasitic wasp rearing device 10 is placed in a designated location in the tobacco warehouse, and the observation device 20 is arranged around the parasitic wasp rearing device 10 in the same environment. At this time, the second generation of parasitic wasps can fly out of the parasitic wasp rearing device 10 through the first opening 101, fly through the mesh 201 into the observation device 20, and parasitize the host larvae inside.

[0050] The second monitor 105 is also connected to the external control system. When conducting statistics, the percentage of parasitic wasps in the parasitic wasp breeding device 10 captured by the second monitor 105 and the number of parasitic larvae in the observation device 20 captured by the first monitor 202 can be calculated.

[0051] Furthermore, the host larvae are artificially raised tobacco mealybug larvae, and the feed used includes the following components by weight: 60% coarse wheat bran, 8% medium-coarse cornmeal, 9% cooked soybean flour, 1% potassium sorbate, 1% yeast, 8% honey, 8% glycerol, and 5% water. The feed is prepared by weighing and mixing the above materials.

[0052] Furthermore, the parasitic wasp rearing device 10 and the observation device 20 should be arranged in an environment with a temperature of 10-40℃ to avoid affecting the vitality of the parasitic wasps.

[0053] Furthermore, a first channel 1061, a second channel 1062, and a funnel 1063 are provided on the outside of the second opening 106. The first channel 1061 is perpendicularly connected to the side wall of the box 102 and is located at the end of the second opening 106 away from the first channel 1061.

[0054] The height of the second channel 1062 is greater than the height of the food storage chamber 102. The second channel 1062 is made of transparent material. When the parasitic wasp feeding device 10 is replenished with honey water, the honey water can be monitored by observing the changes in the liquid level of the second channel 1062.

[0055] Meanwhile, a scale line (not shown in the figure) can be set on the side wall of the second channel 1062. The scale line can display the maximum amount of honey water that can be added, so as to avoid over-addition and overflow.

[0056] Furthermore, a side cover 1011 is provided on the outside of the first opening 101. The side cover 1011 is detachably connected to the first opening 101 and is used to open and close the first opening 101.

[0057] In summary, the monitor of this invention can monitor the parasitic process of parasitic wasps and statistically analyze their parasitic efficiency. It is easy to use and the data obtained is accurate, providing data support for subsequent parasitic wasp deployment operations.
