Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural pest control technology, and in particular relates to a stress chamber for controlling rose thrips. Background Technology
[0002] Dunhuang region boasts abundant sunshine and a large temperature difference between day and night, ideal for rose cultivation, making roses one of the region's important economic crops. However, during the peak blooming season from July to September each year, the hot and dry climate easily triggers large-scale outbreaks of western flower thrips (Frankliniella occidentalis). This pest is tiny and reproduces rapidly. Both adults and nymphs hide inside the flower, scraping and sucking sap, causing grayish-white feeding marks and egg-laying marks on the petals. In severe cases, it causes the flowers to curl, deform, and fail to open properly. Field monitoring data shows that the density of insect eggs in a single affected flower can reach 22±7. The insect secretions and residues further exacerbate the degradation of flower quality, causing a drop in purchase price of more than 20%, seriously damaging the economic benefits of flower growers and consumer satisfaction.
[0003] Current control methods all have significant limitations. In chemical control, while pre-flowering spraying with pesticides like imidacloprid can reduce insect populations to some extent, the uneven flowering period of roses makes precise timing of application difficult. More importantly, pesticide residues violate organic agricultural production standards, impacting product market positioning and export potential. In physical control, hanging yellow sticky traps in the field combined with UV lamps can attract some adults, but its effectiveness against elusive females that lay eggs inside the flowers is limited, with a trapping efficiency of only 55%–70%, failing to interrupt the reproductive cycle. Post-harvest treatment often involves refrigerating at 4℃ for 24 hours to inhibit egg hatching, but this cannot completely eliminate existing eggs and larvae. Consumers may still discover insects while viewing the roses, diminishing the sensory experience and damaging the product's value.
[0004] Therefore, we propose a rose thrips stress control chamber to address the above problems. Utility Model Content
[0005] The purpose of this invention is to address the problem that the control of rose thrips in Dunhuang is limited against female thrips that are highly concealed and lay eggs inside the flower, and to propose a stress chamber for rose thrips control.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A rose thrips stress control cabin includes:
[0008] The enclosed cabin is made of transparent material;
[0009] A flower-carrying module, located at the bottom of the cabin, is used to hold flowers;
[0010] An environmental stress system is used to regulate the environmental parameters inside the cabin, including temperature, humidity, carbon dioxide concentration, sound waves, and light waves.
[0011] The negative pressure collection system includes an air inlet on one side of the cabin and an air outlet on the other side. The air inlet is provided with a grid structure, and the air outlet is equipped with a negative pressure fan to form a directional airflow within the cabin.
[0012] A sunshade mechanism is installed on the top of the cabin to change the light transmittance of the cabin.
[0013] Preferably, the flower-supporting module includes a bed board and a bed layer. The bed layer is installed above the bed board by multiple evenly distributed elastic elements to form an elastic suspension structure. A vibrator is provided at the bottom of the bed layer.
[0014] Preferably, the environmental stress system includes:
[0015] Temperature and humidity detectors and carbon dioxide concentration detectors are installed inside the cabin.
[0016] A steam generator and a carbon dioxide generator are installed inside the cabin.
[0017] A sound wave generator is installed on the side wall of the cabin with the sound wave generating end facing the bed.
[0018] An optical inducer is located at the air outlet.
[0019] Preferably, the optical inducer is an insect-attracting lamp disposed at the suction end of the negative pressure fan, and the light source of the insect-attracting lamp is yellow light with a wavelength of 589nm.
[0020] Preferably, the negative pressure collection system further includes:
[0021] An inactivation device is installed in the suction passage of the negative pressure fan to kill the inhaled pests;
[0022] A collection trough, detachably mounted below the inactivation device, is used to collect the inactivated pests.
[0023] Preferably, the inactivation device is a high-voltage insecticidal grid.
[0024] Preferably, the sunshade mechanism includes:
[0025] Two side-by-side spools are rotatably mounted on the top of the cabin via a spring.
[0026] The shade net has its fixed end wound onto the roller and its movable end equipped with a support rod. A groove is provided at the bottom of the cabin, and the support rod can be engaged with the groove to keep the shade net in an unfolded state to shade the cabin.
[0027] In summary, the technical effects and advantages of this invention are as follows: This rose thrips control stress chamber utilizes a cyclical stress method of "low-temperature high-humidity incubation" and "high-temperature low-humidity expulsion" to specifically regulate the physiological weaknesses of different thrips life stages (larvae / nymphs and adults). First, a 30°C, 85% high-humidity environment induces the concentrated hatching of hidden eggs and increased nymph activity, exposing their presence. Then, a sudden transition to a 50–55°C high-temperature, 30% low-humidity environment, supplemented with 800–1200 ppm CO2, forces adults to detach from the flower under extremely unsuitable conditions. This overcomes the problem of traditional methods being ineffective against hidden life stages, achieving simultaneous and efficient removal of eggs and adults.
[0028] Integrating multiple physical stress factors such as vibration, sound, light, and airflow, the sound wave generator is evenly distributed inside the chamber to generate aversion signals that disturb adult insects from taking flight; yellow light is closely placed at the negative pressure air intake to provide clear visual navigation for the escape of adult insects; and the negative pressure airflow works together to construct a "stress-guidance-capture" pathway, causing adult insects to migrate in a directional manner and gather efficiently at the collection device, thus solving the problem of low efficiency of physical trapping.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0036] Reference Figure 1-5 A rose thrips control stress chamber includes a chamber body 1, a flower-carrying module, an environmental stress system, a negative pressure collection system, and a sunshade mechanism.
[0037] The enclosed cabin 1 is made of transparent material, and the open end face uses a silicone curtain, which not only ensures good sealing to maintain the stability of the internal environment, but also allows the light transmission to utilize outdoor natural light to provide initial heat energy for system operation, achieving energy-saving and green operation.
[0038] The control process consists of two cyclical stages: "low temperature and high humidity incubation" and "high temperature and low humidity expulsion." During the expulsion stage, the environmental stress system creates an environment that forces adult thrips to leave the flower, and combines sound waves and yellow light to induce them to be captured and inactivated by the negative pressure collection system. The shading mechanism is deployed during program breaks or when cooling is needed to help regulate the temperature inside the chamber.
[0039] The flower-carrying module is located at the bottom of the cabin 1 and is used to hold flowers.
[0040] Reference Figure 1-3 The flower-carrying module includes a bed board 5 and a bed layer 6. The bed layer 6 is installed above the bed board 5 by multiple evenly distributed elastic elements 7. The elastic elements 7 are made of springs or silicone pillars to form an elastic suspension structure, making the bed layer 6 a platform that can vibrate elastically. A vibrator 8 is set at the bottom of the bed layer 6. During the high-temperature expulsion stage, the vibrator 8 is activated to generate low-frequency micro-vibration. This vibration is amplified by the elastic elements 7 and evenly transmitted to the flowers on the entire bed layer 6. This vibration, which simulates the natural environment, can effectively disturb the thrips hidden deep inside the flowers, destroy their attachment state, and force them to detach from the flower and enter the air. This greatly enhances the subsequent airflow and light-induced expulsion effect and overcomes the defects of dead zones in traditional static treatment methods.
[0041] The negative pressure collection system includes an air inlet 2 on one side of the chamber 1 and an air outlet 3 on the other side. The air inlet 2 is equipped with a grid structure to prevent large debris from being sucked in. The air outlet 3 is equipped with a negative pressure fan 4 to create a directional airflow in the chamber 1. The negative pressure suction generated by the negative pressure fan 4 can draw away the adult thrips that have been guided to the air outlet 3, preventing them from escaping.
[0042] Reference Figure 1-4 The negative pressure collection system also includes an inactivation device and a collection tank 14.
[0043] The inactivation device is a high-voltage insecticidal grid 13, which is installed on the suction passage of the negative pressure fan 4 to kill the inhaled pests. Adult insects induced to the air outlet 3 will first pass through the high-voltage insecticidal grid 13 at high speed and be instantly inactivated by high-voltage electric shock. The high temperature brought by the electric shock will also cause the insect body to dehydrate and carbonize rapidly, becoming light and brittle.
[0044] The collection tank 14 is detachably installed below the inactivation device to collect the inactivated pests. The dried insect carcasses naturally fall into the collection tank 14, achieving harmless treatment of the insect bodies and eliminating the risk of secondary pollution.
[0045] The environmental stress system is used to regulate the environmental parameters inside the cabin 1, including temperature, humidity, carbon dioxide concentration, sound waves, and light waves.
[0046] Reference Figure 1-3 The environmental stress system includes a temperature and humidity detector, a carbon dioxide concentration detector, a steam generator 9, a carbon dioxide generator 10, a sound wave generator 11, and an optical inducer.
[0047] Temperature and humidity detectors and carbon dioxide concentration detectors are installed inside chamber 1 to monitor environmental parameters in real time, ensuring that all parameters are accurately and stably within preset values. The temperature and humidity during the incubation stage are 30±1℃ / 85±3%, and the temperature and humidity during the expulsion stage are 50-55℃ / 30%.
[0048] Steam generator 9 and carbon dioxide generator 10 are installed inside the chamber 1. Steam generator 9 releases steam through a porous coil (not shown in the attached diagram) extending into the chamber, which can quickly and evenly increase the humidity inside the chamber to the required high humidity level. Carbon dioxide generator 10 releases CO2 directly into the chamber, rapidly increasing the concentration to 800-1200 ppm during the expulsion phase. The high CO2 environment causes thrips to feel suffocated, and in synergy with high temperature and low humidity, it significantly aggravates their discomfort and strengthens their escape behavior.
[0049] The sound generator 11 is installed on the side wall of the cabin 1 with the sound generating end facing the bed 6, and it emits low-frequency sound waves of 170-250Hz. This frequency band of sound waves is an aversion signal to thrips, and can create all-round acoustic stress within their habitat, further driving them away.
[0050] The optical inducer is set at the air outlet 3. The optical inducer is an insect-attracting lamp 12 set at the suction end of the negative pressure fan 4. The light source of the insect-attracting lamp 12 is yellow light with a wavelength of 589nm. After the adult insects are forced to leave the flower, this specific wavelength of yellow light becomes a strong visual guiding beacon, pointing out a unified "exit" direction for the chaotic thrips, causing them to actively gather towards the negative pressure air outlet, thus achieving efficient directional migration.
[0051] The sunshade mechanism is located at the top of the cabin 1 and is used to change the light transmittance of the cabin 1.
[0052] Reference Figure 1-5 The sunshade mechanism includes:
[0053] Two side-by-side spools 15 are rotatably mounted on the top of the cabin 1 via spring 16;
[0054] The shade net 17 has its fixed end rolled up on the roller 15 and its movable end provided with a support rod 18. A groove 19 is provided at the bottom of the cabin 1. The support rod 18 can be engaged with the groove 19 to keep the shade net 17 in an unfolded state to shade the cabin 1.
[0055] When cooling is needed, staff can easily unfold the shade net 17 by simply pulling out the support rod 18 and inserting it into the groove 19. The spring 16 makes the retraction operation equally easy. The unfolded shade net 17 can effectively block most of the direct sunlight. Combined with the ventilation of the negative pressure fan 4, it can accelerate the cooling and dehumidification inside the chamber 1, allowing the system to reset quickly and prepare for the processing of the next batch of flowers. This reduces the reliance on external auxiliary cooling equipment and lowers energy consumption.
[0056] Working principle:
[0057] The harvested rose bouquets were neatly placed on the bed 6 of the flower-carrying module, and the cabin 1 was closed to ensure a seal, ready to execute the first prevention and control cycle.
[0058] The steam generator 9 is activated, releasing steam into the chamber through its porous coils to precisely raise and maintain the humidity at a high level of 85%±3%. Simultaneously, relying on solar energy absorbed by the transparent chamber 1 or an auxiliary heating device, the temperature is stabilized at 30±1℃, simulating a suitable environment for thrips egg hatching. This causes the eggs hidden between the receptacle and petals to hatch within 3 hours, increasing the activity of the nymphs, which then leave their original hiding places and are exposed to subsequent stressful environments.
[0059] After the incubation phase ends, the system automatically switches to expulsion mode, and environmental parameters change drastically:
[0060] Environmental stress: Steam generator 9 stops working, negative pressure fan 4 starts and works with shading mechanism to cool and dehumidify, causing the temperature inside the chamber to rise sharply to 50-55℃, while the humidity drops sharply to about 30%. Carbon dioxide generator 10 starts and releases CO2 into the chamber, causing the concentration to quickly reach 800-1200ppm. The triple stress environment of high temperature, low humidity and high CO2 causes thrips to become severely dehydrated and suffocated, generating a strong escape instinct.
[0061] Vibration disturbance: The vibrator 8, located at the bottom of the bed 6, is activated to generate low-frequency micro-vibrations. These vibrations are evenly transmitted to the flowers, effectively disturbing and driving away adult insects hiding deep within the flowers, forcing them to fly away from the flowers.
[0062] Sound wave repulsion: The sound wave generator 11 emits low-frequency aversive sound waves of 170-250Hz to create acoustic stress throughout the cabin, further preventing the adult insects from falling back and driving them to gather in the air.
[0063] Light-induced orientation: The 589nm yellow light insect-attracting lamp 12, set at air outlet 3, is lit up to provide a clear optical guidance signal for the thrips flying haphazardly in the air.
[0064] Airflow guidance and capture: The negative pressure fan 4 works continuously, forming a stable directional airflow from the air inlet 2 to the air outlet 3 in the chamber. Adult insects that are coerced or disturbed and fly away will instinctively tend to the more "comfortable" airflow outlet direction under the drive of the averse environment, and will be precisely guided by the yellow light to the vicinity of the air outlet 3.
[0065] The adult thrips induced to the air outlet 3 are first sucked in by the airflow and then passed through the high-voltage insecticidal grid 13, where a high-voltage electric shock is released instantly to inactivate the insects. The inactivated and dried insect carcasses naturally fall into the collection trough 14 below, which can be easily pulled out, thus achieving harmless treatment and collection and eliminating the risk of live insects escaping or the collection device becoming clogged.
[0066] After one "hatching-removal" cycle is completed, the next cycle can be started as needed to ensure that the eggs with inconsistent hatching cycles are completely eliminated.
