Description

Technical Field

[0001] The present invention relates to the technical field of photophysical green prevention and control of locust agricultural pests, and specifically to a locust killing and collecting device with induction type thermal fog coupled with linear polarized light and analyzer polarized light. Background Art

[0002] Locust plagues are one of the most frequent and significant insect pests affecting my country's agricultural production, characterized by sudden, migratory, and devastating outbreaks. In recent years, the frequent occurrence of catastrophic climate events has fostered locust outbreaks, potentially threatening agricultural production safety. Currently, there is a lack of effective control measures for locust pests, and excessive reliance on pesticides is severely hampering the development of the Green Revolution in agriculture. Consequently, with the fundamental goal of ensuring national agricultural and forestry production safety, agricultural product quality safety, and agricultural and forestry ecological security, and based on the theory of preventable, controllable, and curable green pest control, my country has developed an integrated technology for locust monitoring, early warning, and precise green pest control, using physical pest control measures. This technology addresses the need for green pest control against locusts, a type of agricultural pest, and focuses on combating these pests. The integrated innovation and development of a thermal mist-based killing and collection device, which uses linear polarization and analyzer light coupled to induce killing, is part of the photophysical pest control technology sector. This technology meets the needs of modern agricultural green and sustainable development, aiming to address the pesticide dependency of agricultural production methods.

[0003] Based on the insect phototaxis mechanism, light-induced control technology and its application strategies have been successfully applied to nocturnal pests such as Lepidoptera, Coleoptera, and Hymenoptera, as exemplified by Chinese patent publications CN2190405Y and CN2481139Y. Furthermore, national standards GB / T 24689.2-2017 and industry specifications NY / T 36979-2020 have been established for the production and application of insecticidal lamps. The phototaxis of Orthoptera locusts is more complex than that of noctuid moths, and their phototaxis is constrained by their phototaxis threshold tolerance and physiologically induced response threshold. Research on the structure of polarization-sensitive neural tissue and the physiology of polarization navigation behavior in locusts has expanded the understanding of the regulatory factors governing the visual physiological stimulation and biological response effects of locust phototaxis, and has promoted the development of polarization-based, green control technologies for locusts.

[0004] Currently, the common feature of physical locust killing and collection technologies is the utilization of thermal effects to regulate and induce mutations in locust biological activity. For example, mechanical suction capture technology, Chinese patent applications CN201711488134.2, CN90224472.8, and CN91208749.8, use hot water spraying to treat locusts clinging to grass. Microwave insecticide technologies, such as Chinese patents CN2534824Y, CN101218907A, and CN102422834, utilize the effect of concentrated heat killing. Biophotoelectric spectrum trapping technology utilizes the photothermal mutagenic effect. Therefore, the implementation of thermal effects can effectively stimulate the biological activity of locusts, and locusts exhibit a thermophilic characteristic in nocturnal environments. At the same time, the Chinese patents for locust phototactic capture and control technology ZL0310113391.X, ZL0410096643.7, ZL0420116184.X, ZL200310113391.X, ZL20132015944 2.1, ZL201410312673.0, and ZL201410312688.7 integrate three technologies: photoelectric induction and control of locusts at night, mechanical sliding air suction capture, and locust photobiological activity stimulation. This allows for the control and management of locust disasters in farmland, grasslands, woodlands and other areas, as well as their resource-based capture and utilization. However, issues such as locust photobiological activity stimulation, visually sensitive phototactic characteristics and factors, and photoinduced physical killing and collection restrict the application of this technology.

[0005] Based on the progress of information, intelligent and mechanized technologies, and focusing on the low-reliability operation problems caused by the flexible bodies of crops and complex farmland environments, it is crucial to use photophysical mechanisms for specific locust control and avoid the impact of killing measures on the environmental ecology based on the high correlation requirements among technology, equipment and animals and plants.

Moreover, the heat source effect formed by the diffusion effect of the hot mist realizes the biological characteristics of the locusts' light-induced thermotaxis and thermotaxis, and obtains the enhanced aggregation induced by the photothermal coupling and the enhanced control effect of the light-heat mutual lighting of the locusts.

[0032] The locust linear polarized light and analyzer polarized light coupling induction system 4 implements the functions of directional control and induction of locusts and close-range aggregation control by using heterogeneous spectrum and different polarization vector illumination properties in different circumferential directions, and obtains the staggered stimulation enhancement sensitivity of locusts' tendency to visual deviation and the enhanced sensitivity of visual tendency control under the coupling control mode of heterogeneous spectrum linear polarized light and linear analyzer polarized light, and utilizes the thermal diffusion effect of atomized steam sprayed by hot mist nozzles to obtain heat source stimulation measures for phototactic locusts, thermal biological activity enhancement effect and locust thermotaxis effect, and finally realizes the induction and control of locust tendency to thermotaxis.

The box is made of box plates and corresponding closing plates, and an insect retrieval mouth is set on the box wall and closed by a closing plate. At the same time, according to the terrain characteristics, the box can be placed on the ground to collect locusts.

[0034] The working principle of the present invention is:

[0035] Aiming at the characteristics of polarization orientation behavior of aerial migratory locusts, the long-range induction effect of spectral light quality photoinduced polarization visual sensitivity vector of locusts on locust orientation, the specific sensitivity of spectral linear polarization vector illumination to stimulate locust orientation response characteristics, the strengthening effect of coupled spectral illumination on locust phototaxis, the stimulating and regulating effect of linear polarization light and spectral light coupled illumination on locust orientation and phototaxis vision, and the requirements of locust phototaxis and polarization illumination characteristics, the converging light beam of the concave spherical purple spectrum LED array is combined with a 120° vector linear polarizer to form a linearly polarized purple spectrum 120° vector searchlight beam, and the outer orange and inner purple spectrum is connected with it. The coupled searchlight beam combination of the LED array forms a coupled searchlight beam illumination mode of linearly polarized violet spectrum 120° vector illumination and orange-violet spectrum illumination, realizing the coupled induction effect of locust phototaxis and phototropism, in which linearly polarized vector illumination stimulates the polarized visual orientation of locusts and spectrum illumination stimulates the compound visual orientation of locusts, thereby obtaining the multiple stimulation effects of long-distance searchlight induction on target locusts. The single-chip microcomputer control system is used to control the rotation stop function of the coupled illumination system driven by the high-torque DC motor. Combined with the external command input, the stimulation mode of the coupled searchlight beam pointing to the target locust is implemented, thereby obtaining the directional induction effect of the searchlight beam pointing to the target locust.

[0036] Aiming at the characteristics of the polarization response of solitary and gregarious locusts on different plants, the specific effect of heterogeneous spectral linear polarization vector illumination on the visual sensitivity of locusts to polarization, the induced and enhanced effect of heterogeneous spectral linear polarization and linear-detection vector illumination on the polarization orientation of locusts, the staggered regulation effect of heterogeneous spectral linear polarization and linear-detection vector coupling illumination on the polarization vision of locusts, and the close-range manipulation effect of linear polarization and linear-detection vector illumination on the intensity of polarization response of locusts, purple and orange spectrum LED arrays are arranged at intervals on the six-sided lamp body, and linear polarizers, 0° linear polarizers and different vector linear polarizers are combined. For purple and orange spectra, 150° vector linear polarization of purple spectrum, 180° vector linear polarization of orange spectrum, 0° vector linear polarization of purple spectrum, 180° vector linear polarization of orange spectrum and 150° vector linear polarization of purple spectrum are formed respectively. 180° vector line-detected polarized light and orange spectrum 0° vector line-detected polarized light are finally made into a hexahedral light source with purple-orange spectrum interval distribution and different linear polarization vector illumination properties in six directions, realizing the induction and regulation of locust tendency and orientation by heterogeneous spectrum line polarization and line-detected polarization vector illumination in the circumferential direction, and utilizing the visual excitation effect of linear polarization and line-detected polarization spectrum vector illumination on locust tendency vision, regulating phototactic locusts to realize polarization directional conversion, obtaining the locust tendency and aggregation enhancement effect, and utilizing the linear polarization heterogeneity coupling illumination at adjacent points of the hexahedral linear polarized light source to obtain the locust compound vision multiple stimulation effect, strengthening the locust tendency and aggregation sensitivity effect, realizing the polarization close-range control of locust tendency and aggregation and the lighting enhancement effect, and achieving the thermal shock touch and insect killing effect of locusts tending to be lit. At the same time, the heat source formed by the thermal mist diffusion effect in the thermal killing measures effectively stimulates locusts to produce enhanced thermal-induced aversion activity and thermotaxis, strengthens the locusts' aversion orientation, obtains the photothermal coupling induction effect and the photothermal mutual reinforcement aversion and thermotaxis coupling induction effect, strengthens the locusts' sensitive response to aversion and thermotaxis aggregation, and the photothermal interaction effect, effectively controls the realization of lighting up locusts at close range, and obtains a thermal killing effect.

[0037] Aiming at locusts that tend to gather towards light, heat and deflection, on the basis of stimulating the locusts to produce the behavior effect of approaching the light under the action of light-heat coupling, the intermittent pulse atomized steam field sprayed downward by the atomizing nozzle is used to touch the locust organisms that are approaching the light, achieving the steam thermal shock killing effect, and the locusts caused by the thermal shock fall into the box through the insect drop mouth and are collected.

[0038] In this way, through the light beam search stimulation of linear polarized spectrum vector illumination coupled with spectrum illumination, the visual sensitivity of locusts to polarization and phototaxis is effectively stimulated, and the multiple effects of locusts' long-range polarization orientation and spectrum induction are achieved. The target induction of migrating locusts in the air is effectively obtained by utilizing the rotational directionality directional search stimulation of the DC motor. Moreover, the implementation of the vector illumination mode of linear polarized heterogeneous spectrum and linear detection polarized heterogeneous spectrum effectively regulates the intensity of locusts' tendency to orient themselves, controls the realization of locusts' tendency to polarize and aggregate, and obtains the close-range aggregation enhancement effect of locusts that tend to polarize and phototaxis. The diffusion effect of hot steam obtains the thermal and photoinduced coupling photothermal regulation aggregation induction effect. Under the stimulation and strengthening effect of the photothermal coupling effect, the intensity of the locusts' photothermal biological behavior activity is accelerated to undergo a drastic change, and the locusts are manipulated to produce light-seeking behavior. Then, under the action of thermal shock, the sliding function of the insect drop funnel of the box is used to collect the falling locusts, effectively solving the problem of the difficulty in killing locusts that follow the light. Furthermore, the implementation of coupled phototaxis and thermotaxis measures effectively addresses the challenges of weak locust photobiological activity and the difficulty of induced aggregation. The thermal diffusion effect of steam effectively expands the killing range of aggregated locusts, addressing the difficulty of killing locusts with different behavioral characteristics. Furthermore, the suspension and box-supported shelf design can be adjusted to suit terrain characteristics, effectively applying the induced killing and collection of locusts in various locations.

[0039] The basic principles, main features and advantages of the present invention are shown and described above. Without departing from the spirit and scope of the present invention, the present invention may also be subject to various changes and improvements, which fall within the scope of the present invention to be protected.
