Description

Technical Field

[0001] This invention belongs to the fields of insect biotechnology, pest breeding and rearing, and particularly relates to a blue light-induced green breeding device and method for western flower thrips. Background Technology

[0002] Western flower thrips ( Frankliniella occidentalis As a major global pest, western flower thrips has a wide host range and can damage various vegetables, flowers, and cash crops. It is characterized by rapid reproduction and severe damage, seriously affecting crop yield and quality. In greenhouse vegetable and flower production, the long-term excessive use of chemical pesticides not only easily leads to increased pesticide resistance in pests but may also cause excessive residues in agricultural products and environmental pollution. Therefore, promoting "pesticide reduction and pest control" and adopting green control technologies has become an urgent need for sustainable agricultural development. The release of natural enemy insects and the application of biological pesticides, as important alternatives to chemical control, highly rely on healthy, standardized, and stably supplied pest sources for their effectiveness evaluation and population maintenance. Therefore, there is an urgent need to establish an efficient and controllable indoor breeding system for western flower thrips.

[0003] Currently, the reproduction of western flower thrips mainly relies on traditional plant host (such as green beans) rearing methods. This method suffers from low reproduction efficiency, cumbersome management, and susceptibility to mold growth on host materials, leading to large fluctuations in thrips populations and requiring frequent manual monitoring and host replacement, severely impacting the continuity of experiments and the reliability of data. On the other hand, existing research has shown that western flower thrips exhibit a strong attraction to specific light waves, particularly blue light around 420 nm, which has a significant attracting effect. However, existing light-attracting devices are mostly used for field monitoring or trapping and have not yet been effectively integrated with indoor breeding systems. Furthermore, there is a lack of integrated design considering both the western flower thrips' "blue light attraction and habitat environment," leaving its potential for indoor breeding far from being realized.

[0004] Therefore, there is an urgent need to develop a specialized breeding device that can effectively integrate blue light attraction technology with microenvironment regulation function to achieve efficient and stable reproduction of western flower thrips, and provide reliable insect source support for its green control and biological control research. Summary of the Invention

[0005] The present invention aims to address the aforementioned problems and defects by providing a blue light-induced green propagation device and method for western flower thrips, which solves the problems of low propagation efficiency and difficult host management in the prior art.

[0006] The present invention is implemented using the following technical solution.

[0008] The method for using the above-mentioned blue light-induced green reproduction device for western flower thrips includes the following steps. S1 device assembly: Fix the blue light attracting mechanism 1 to the upper middle part of the breeding box 2, ensuring that the hanging hole 1.1 and the connecting hole 1.5 are in the correct positions; install the habitat breeding mechanism 3 at the lower part of the breeding box 2, below the blue light attracting mechanism 1; S2 Substrate Preparation: Evenly spread a layer of fine sand 5 at the bottom of the habitat and breeding structure 3, with a thickness of about 1-2 cm; then lay filter paper 4 on the surface of the fine sand 5 to form a moisture-retaining layer for absorbing and retaining moisture; S3 Feed Placement: Take fresh green beans, place one end on the small wooden board 3.1, and let the other end naturally contact the filter paper 4. Avoid direct contact between the green beans and wet sand to prevent mold growth and provide food and spawning grounds for western flower thrips. S4 Circuit Connection: Connect and fix the LED 1.4 to the thin iron wire 1.2 through the connection hole 1.5; install the battery 1.7, preferably a replaceable dry cell battery, in the battery slot 1.6, and connect the circuit through the switch 1.3 to ensure that the LED 1.4 can be turned on and off normally; S5. Start-up: Turn on switch 1.3, and LED 1.4 emits 420 nm blue light to attract western flower thrips into habitat and breeding facility 3, where they feed, lay eggs, and reproduce on the green beans; regularly replace the green beans and maintain the filter paper moisture layer to ensure efficient reproduction; S6. Close the breeding box: Tighten the cover 2.1 onto the main body of the breeding box through the threaded section 2.2, ensuring that the ventilation screen 2.3 is unobstructed, so as to achieve internal ventilation while preventing the western flower thrips from escaping.

[0009] The beneficial effects of this invention are as follows: It utilizes blue LED beads of a specific wavelength (420 nm) to attract western flower thrips, combined with an optimized habitat and breeding mechanism, achieving efficient and convenient breeding. The blue light attraction mechanism is compact, battery-powered, and allows for flexible adjustment of the light's on / off state, resulting in excellent attraction. The breeding box features a lid design and ventilated mesh, facilitating operation while ensuring ventilation and preventing escape. The habitat and breeding mechanism, with its rationally arranged components such as small wooden boards and inverted concave boards, effectively prevents mold growth on the green bean plants and enhances the stability of the habitat environment. Filter paper and fine sand form a moisture-retaining layer, maintaining suitable humidity. The overall device is low-cost, simple to operate, environmentally friendly, and safe, suitable for laboratory and large-scale breeding needs. It significantly improves the breeding efficiency and success rate of western flower thrips, thus providing a high-quality insect source for the utilization of natural enemies, screening of biological pesticides, and monitoring of pesticide resistance in the green control technology system for western flower thrips.

Example

[0037] Western flower thrips were collected from the back hill of Yunnan Agricultural University. The collected thrips were placed in an artificial climate chamber for experimentation to simulate the suitable environment for their natural reproduction. The temperature was controlled at 25±1℃, relative humidity at 60%-70%, and photoperiod at 16L:8D. Five treatment groups were set up: the complete device of this invention (including a blue light attraction mechanism, a habitat and breeding mechanism, and a filter paper + fine sand moisture-retaining layer); the invention without a blue light attraction mechanism (only the breeding box, habitat and breeding mechanism, and filter paper + fine sand were retained); the invention without a habitat and breeding mechanism (only the blue light attraction mechanism, breeding box, and filter paper + fine sand were retained); the invention without a filter paper and fine sand moisture-retaining layer (only the blue light attraction mechanism, breeding box, and habitat and breeding mechanism were retained); and the traditional green bean rearing method (no special device, only green beans were placed in plastic boxes). Each treatment had three replicates. Each device contained 30 healthy adult western flower thrips and was fed with fresh green beans (4 segments, 2 cm in length). After 24 hours of egg-laying, the adults were removed. The hatching of western flower thrips was observed and recorded daily until no nymphs hatched from the green beans for five consecutive days. The number of hatched nymphs in each treatment was recorded and summarized. Meanwhile, the hatched nymphs were individually placed in a petri dish and fed with fresh green beans, and were numbered. 100 first-instar nymphs were selected from each treatment to observe the survival rate of western flower thrips at each instar and their reproductive number in their lifetime when they develop into adults.

[0038] Table 1. Number of Western Flower Thrips Nymphs Hatching under Different Treatments

[0039] Note: Different letters indicate significant differences in the number of western flower thrips nymphs hatched from each treatment. P < 0.05).

[0040] The comparison of the number of nymphs hatched under different treatments (Table 1) shows that there were significant differences in the number of nymphs hatched among the different treatments. P < 0.05). Under traditional green bean rearing methods, the nymph hatching rate is the lowest, at 67±4.04 individuals; without the blue light trapping mechanism, the hatching rate is 85.00±3.46 individuals; without the habitat and breeding mechanism, the hatching rate is 99.00±4.00 individuals; without the filter paper and fine sand moisture-retaining layer, the hatching rate reaches 115.33±5.13 individuals; using the scheme of this invention, the nymph hatching rate is the highest, at 158.87±6.65 individuals. The various devices of this invention (filter paper and fine sand moisture-retaining layer, habitat and breeding mechanism, and blue light trapping mechanism) work synergistically to maximize the nymph hatching effect, providing an efficient breeding foundation for the expansion of western flower thrips populations or related research.

[0041] Table 2. Survival rate of western flower thrips at different ages under different treatments.

[0042] Note: Different letters in the same column indicate significant differences in the number of surviving western flower thrips at different ages under different treatments. P <0.05).

[0043] The comparison of survival numbers at different instars under different treatments (Table 2) shows that the survival number of first instar was 100 in all treatments (with the same initial insect population), and the differences became significant from the second instar onwards. P < 0.05). Under traditional green bean rearing methods, the number of second-instar surviving insects was 42.33±2.08, prepupae 29±1.73, and adults 23.67±1.53. In this invention, without the addition of a blue light trapping mechanism, the number of second-instar surviving insects was 46.33±2.89, prepupae 33.33±3.51, and adults 27.00±3.00. In this invention, without the addition of a habitat and breeding facility, the number of second-instar surviving insects was 56.33±2.31. The initial count was 41.33±1.53 prepupae and 32.33±6.58 adults. Without the filter paper and fine sand moisturizing layer, the second instar count was 64.33±2.52, prepupae 45.33±1.53, and adults 39.00±3.61. Using the method described in this invention, the second instar count was 73.33±3.21, prepupae 55.33±2.52, and adults 43.67±0.58. The synergistic effect of the components in this invention significantly improves the survival rate of thrips at all instars, creating a favorable environment for their growth and development, and promoting the sustainable development of the thrips population.

[0044] Table 3. Number of adult western flower thrips throughout their life cycle under different treatments.

[0045] Note: Different letters indicate significant differences in the number of adult western flower thrips that reproduce over their lifetime under different treatments. P <0.05).

[0046] The comparison of the number of adult western flower thrips during their lifetime under different treatments (Table 3) shows that there are significant differences in the number of adults among the treatments. P < 0.05). Under traditional green bean rearing methods, the reproduction rate is the lowest, at 117.33±4.04 individuals; without the blue light trapping mechanism, the reproduction rate increases to 143.00±11.79 individuals; without the habitat and breeding mechanism, the reproduction rate is 184±5.20 individuals; without the filter paper and fine sand moisture-retaining layer, the reproduction rate reaches 216±4.04 individuals; using the scheme of this invention, the reproduction rate is the highest, at 263.00±8.72 individuals. The synergistic effect of the components of this invention greatly enhances the reproductive capacity of adult thrips, providing efficient technical support for large-scale rearing or population dynamics research of western flower thrips.

[0047] The above experimental results show that the experimental group using the complete device of this invention significantly outperformed other treatment groups in terms of hatching rate, nymph survival rate, and single female reproduction rate of western flower thrips, verifying the high efficiency of the synergistic effect of blue light trapping and optimized habitat environment. This device design is not only highly effective, but also possesses the potential for modular production and rapid promotion due to its simple structure and high degree of standardization. It can be deployed and applied as standardized insect source production equipment in facility agriculture parks and biological control enterprises. Furthermore, by adjusting the size of the breeding box or connecting multiple units in parallel, it can easily adapt to the requirements of insect source production capacity construction at different scales. At the same time, the device and method used in this invention are significantly superior to traditional western flower thrips breeding methods. This invention, through the organic combination of blue light trapping and optimized breeding habitat structure, combined with the stable microenvironment created by filter paper and fine sand moisture-retaining layers, significantly improves the breeding efficiency and population survival rate of western flower thrips. This device is suitable for various scenarios such as laboratory research and large-scale breeding of natural enemies. It features a reasonable structure, simple operation, low cost, and environmental friendliness and efficiency. The blue light attraction mechanism can be flexibly opened and closed as needed, the habitat and breeding mechanism effectively prevents host mold growth, and the breeding box combines ventilation and escape prevention. The overall design is scientific and practical, filling the technological gap in existing high-efficiency breeding devices for western flower thrips and providing a reliable source of insects for related biological research and integrated pest management.
