| 摘 要： | 为了探索东亚飞蝗视觉响应LED光信号的视敏反应效应,以明确东亚飞蝗趋光的光敏响应因子和生物光诱参数,利用LED光照和Ava Spec光纤光谱仪系统,在室内进行了东亚飞蝗视觉响应表征的光谱测定。并在此基础上,利用该波谱光照装置,验证其波谱光照调控东亚飞蝗的趋光反应及响应程度。测定结果显示,东亚飞蝗复眼吸收365、400、520、610 nm波长光照射后,其视觉响应波谱表现为380、402、540、602 nm的微光特征,当波谱光照强度增加时,东亚飞蝗视觉微光反应随之增强,且呈现时变效应的调控特性。东亚飞蝗视觉光敏调控的时变强度以紫光最优、依次是橙光和绿光最差,而其调控容度以橙光最优、绿光次之和紫光最差,紫外光较快的光敏聚集速度、紫光较强的光敏聚集程度和橙光较好的趋光效果说明,趋光光敏活性、趋光程度和趋光效果分别与视觉激发强度和视觉光敏调控的时变强度以及视觉光敏调控容度呈正相关,且东亚飞蝗视觉反应强度的光敏时效性影响其趋光行为选择和视觉光敏活性。因此,依据紫外光较强的激发效果、橙光较好的光敏时效性和紫光较强的光敏调控强度的特性,进行趋光视敏性光照时间的刺激调控,可以增强东亚飞蝗的趋光效果。该研究结果为蝗虫光诱捕机械装备的研制提供了理论基础和技术指导。

| Abstract: | To explore the visual acuity reaction effect of Locusta migratoria responding to LED light signal, clear the photosensitive response factor and the biological light inducing parameters of Locusta migratoria phototaxis regulated by light, the spectral representation of Locusta migratoria visual reaction stimulated by LED light source was investigated with AvaSpec fiber-optic spectrometer system. On this basis, the degree of Locusta migratoria phototactic response and reaction regulated by spectral light was certificated comparatively through utilizing the investigated device of Locusta migratoria phototactic response to spectral illumination. The results showed that the visual reaction was represented to 380nm, 402nm, 540nm and 602nm glimmer characteristics when Locusta migratoria visual system accepted to absorb 365nm, 400nm, 520nm, and 610nm light photons, and spectral illumination was enhanced, the visual spectral transmission peak amplitude was increased to take on the reaction characteristics of time-varying effect, which originated from the difference of photo physicochemical reactions and light-sensing deconstruction effect of the visual system absorbing different spectral photons, and the visual sensitivity degree of responding to different spectral light stimulation was manifested by visual spectrum peak misregistration and visual spectrum emission amplitude. Moreover, time varying intensity of Locusta migratoria visual photosensitivity regulation to violet light was the optimal, the following was orange light, and green light was the worst, the visual photosensitivity regulation capacity for orange light was the optimal, the following was green light, and violet light was the worst. Simultaneously, the superior photosensitive aggregating speed for UV light, the better photosensitive aggregating degree for violet light and the better phototactic effect for orange light showed that the phototactic photosensitivity activity, phototactic degree and the phototactic effect were positively correlated with visual stimulation intensity, tim-varying intensity of visual photosensitivity regulation and visual photosensitivity regulation capacity, respectively, and the photosensitive time effectiveness of the visual reaction intensity affected the behavioral selection effect and visual photosensitivity activity effect. Then, based on the stronger stimulating effect of UV light, the better time effectiveness sensitivity of orange light and the stronger photosensitive regulation intensity of violet light, Locusta migratoria phototactic effect can be improved by stimulating time regulation with the combination of UV, violet and orange light. Research results provided theoretical support for the study of trapping mechanical equipment of Locusta migratoria induced by light. |
