蝗虫视觉光谱效应与趋光响应光谱的对比测定

摘要

为给蝗虫诱导光场光谱的确定提供理论支持，探讨蝗虫趋光性视觉机理，利用AvaLight-DHS光源和AvaSpec光纤光谱仪系统，进行了蝗虫视觉系统接受光照能量刺激后蝗虫视觉光谱效应的测定，在此基础上，利用蝗虫趋光响应光谱装置，对照验证蝗虫趋光响应光谱差异性。结果表明：蝗虫视觉系统对430，545，610 nm单光光子的吸收程度显著且存在差异，行为响应表现为蝗虫对橙、紫、绿、蓝光光照具有选择敏感差异性，并以紫光响应活动强度最大，橙光响应程度最优，同时，蝗虫对光谱光子能量吸收具有选择差异性和光照时间的要求，而光谱的敏感程度及光照能量的强弱，影响蝗虫趋光定向响应程度，且蝗虫光感受器对光子能量强度的吸收转化，所致蝗虫趋光视觉生物光电效应的生理微反应，是蝗虫趋光响应的原因，因此，蝗虫视觉光谱效应，仅在蝗虫视觉生物光电效应被光谱光照激活状态下，才能呈现出光谱吸收效应的敏感性，依据紫光较强的粒子激发性，进行橙、紫、绿、蓝光谱光场机制的合理组合，可形成有效的蝗虫趋光诱集光场，然而，蝗虫趋光机理的阐述缺乏量化性数据，尚需进行光照刺激蝗虫的趋光行为、视觉电位及视觉光谱效应的测定对照，来完善蝗虫趋光机理。%To provide theoretical support for determining locust’s phototactic spectrum ,and explore locust’s phototactic mecha-nism stimulated by light ,utilizing AvaSpec fiber-optic spectrometer system and AvaLight-DHS ,the investigation of locust’s phototactic visual spectrum effect after light energy stimulated locst ’s vision system was carried out and on this basis ,utilizing the investigated device of locust’s phototactic response to spectral illumination ,the discrepancy of locust’s phototactic response to spectral illumination was certificated comparatively .The results show that the degree of locust’s vision system absorbing the single spectrum photon of 430 ,545 and 610 nm is significant and there exists difference ,and the behavioral response to orange , violet ,green ,and blue spectral light has the difference in selective sensitivity ,with the intensity of response to violet light being the strongest .The degree of response to orange light is the maximum ,simultaneously ,locust’s vision system absorbing spectral photon energy has selective difference and requirement of illumination time ,moreover ,the sensitive degree of locust’s visual sys-tem to spectrum and the strength of the lighting energy ,influencing locust’s phototactic response degree ,and the micro-re-sponse of locust’s phototactic vision physiology ,led by the photoelectric effect of locust absorbing sensitive photon and conver-ting photon energy ,is the reason for locust’s phototactic orientation response .In addition ,locust’s phototactic visual spectrum effect ,only when the biological photoelectric effect of locust’s visual system is stimulated by spectral illumination ,can present the sensitivity of the spectral absorption effect ,so ,using the stronger ultraviolet stimulation characteristic of violet light ,the different sensitive stimulation of orange ,green ,blue spectral light on locust’s phototactic vision ,and combining orange ,violet , green ,blue spectral light field mechanism reasonably ,can form the optical field trapping locusts effectively ,while ,the elabora-tion of locust’s phototactic mechanism lacks the quantification data ,the comparative investigation of locust’s phototactic behav-ior ,locust’s visual electric potential and locust’s visual spectrum effect has to be done ,to improve and perfect the theory of lo-cust’s phototactic mechanism .
