东亚飞蝗对波谱光及其偏光对比选择性视励效应的测定

Comparative Investigation of Locusts Visual Bio-selection Response Effect Induced by Incentive Effect of Polarized Light and Spectral Light

为明确蝗虫对波谱光及其偏光视励效应的视敏选择差异,确定蝗虫趋光趋偏的视励影响因素及视敏信息,针对波谱光与其偏光光照中东亚飞蝗光生物响应的视选择效应试验,分析了东亚飞蝗趋光趋偏选择差别的视控作用及响应波谱光和其偏光的视敏因素及视励强度。结果表明,波谱光与其偏光叠加作用下的光聚集程度呈现偏光矢量调控性生理响应敏感差异,并在光强度增强时,视偏响应敏感的偏光矢量发生变化,且210°及120°紫偏光、210°橙偏光与其波谱光的耦合刺激效应较优,而270°时紫外与其偏光的耦合效应最差;东亚飞蝗视激发状态下的光选择性趋向于视励强度较弱的偏光,且波谱光强度的视敏激发效应及偏光矢量的视励敏感程度削弱东亚飞蝗的视控定位功效,并以紫外及紫偏光矢量引起的趋偏视敏性较强而蓝橙光较弱,而90°及270°时弱偏光的视励效应致使波谱光的激发效应主导东亚飞蝗的视选择强度,且光源光照度增强,东亚飞蝗视偏敏感选择强化程度以紫偏光较强、120°紫外偏光较弱,且波谱光选择弱化程度以90°蓝偏光较强;东亚飞蝗对波谱光与偏光耦合光照的聚集响应差异及趋光趋偏选择强度差异,源于偏光矢量激励及波谱光质激发东亚飞蝗视觉引起的协同增效或相互拮抗性视反应调控输出效应,且波谱光照强度削弱偏光矢量信息的选择强度,但东亚飞蝗生物光敏响应与波谱光质的敏感性相关而光强度作用不大,且波谱光与偏光的耦合性光照梯度抑制蝗虫的视感响应强度。研究结果为适应各种作业的害虫光诱型农机产品开发及蝗虫视响应机理探讨提供了支撑。

With the aim to definite the visual sensitivity selection difference of locusts biological response inspired by the visual excitation effect of spectral and polarized light,and determine the visual excitation factor and the visual sensitivity information of locusts phototactic and polartactic selection,based on the investigated experiment of swarm locusts biological selection effect responding to spectral light and polarized light respectively,the visual regulating function of locusts phototactic and polartactic selection disparity,the visual sensitivity factors and the visual exciting intensity of locusts stimulated by spectral light and polarized light were analyzed. Results show that locusts light aggregation degree induced by the superimposition function of spectral and spectral polarized light presented the sensitivity difference of physiological response to the regulation of polarized light vector, but when light stimulus intensity increased,the sensitive polarization vector of locusts visual response orientation changed, and the photosensitive biology aggregation response effect stimulated by the coupling light stimulation effect of210°,120° vector of violet polarized light and violet light,210° vector of orange polarized light and orange light was the better,while that of 270° vector of violet polarized light and violet light was the worst. Locusts visual light selectivity with the visual excitation state tended to polarized light with the weaker stimulation intensity,spectral light stimulation intensity and polarized light vector sensitive degree weakened locusts positioning control behavior,and locusts polartactic vision sensitivity inspired by UV and violet polarization vector was the stronger while blue and orange polarization vector was the weaker,but 90°,270° vector of polarized light made the stimulation effect of spectral light dominate light selectivity intensity. Moreover, the enhanced degree of locust visual sensitivity selection to violet polarized light,120° vector of UV polarized light caused by the increment of the stimulating intensity was the stronger and the weaker respectively,and the weakened degree of spectral light selectivity caused by90° vector of blue polarized light was the stronger. Thus,the aggregation difference of locusts response to spectral light coupling with polarized light and the selection intensity difference between spectral light and polarized light, originated from the regulated output effect of light reaction synergistically or antagonistically generated by the incentive of polarized light vector and the stimulation of spectral light,and spectral light intensity could weaken the intensity of selection to polarization vector information,but locusts bio-photosensitive response and spectral light sensitivity presented significant correlation,and the light gradient of spectral light coupling with polarized light, significantly affected locusts sensitive response intensity,while light stimulation intensity effect was not significant. Research results provide theoretical support for the manufacture of the agricultural pest induction machinery product and locusts visual response mechanism.
