摘要
为确定线偏波谱检偏矢量光照对蝗虫趋偏响应的调控效应,利用自制的检偏光照调制模块和蝗虫趋偏响应试验装置,测试了蝗虫对线偏波谱检偏矢量光照的趋偏响应,分析了线偏波谱照度对蝗虫趋偏响应的影响和蝗虫检偏矢量敏感模式的光致变化特异性。结果表明:蝗虫趋偏响应呈线检偏矢量敏感差异性弦函性响应特征,其中,波谱决定蝗虫趋偏响应的特异敏感性。蝗虫趋偏视觉的视距性敏感矢量与线偏波谱照度有关:在100 lx时,紫光波段导致的蝗虫趋偏聚集响应敏感性较强,而紫外光波段导致的视趋响应敏感性较强;1000 lx及光照能量相同时,紫光波段导致的蝗虫趋偏响应敏感性较强。随线偏光照度增强,蝗虫的趋偏性矢量敏感模式重置,并导致蝗虫的趋偏响应敏感性发生变化,线偏紫光波段照度的强化效果显著,线偏紫外照度的调控效果显著,线偏蓝绿照度的抑制效果显著。蝗虫对线检偏矢量(±180°、0°、±90°)的对抗敏感特性与线偏波谱的照度有关,±90°时线检偏弱光照的抑制效果和0°、±180°时线检偏强光照的强化效果均与线偏波谱照度或光距刺激有关:1000 lx下,蝗虫的趋偏响应敏感性在线偏紫波谱±90°时最强,在线偏橙波谱±180°时次强;光照能量相同时,蝗虫的趋偏聚集响应敏感性与视趋响应敏感性在线偏紫波谱±180°下最强,在0°下次强。研究结果可为蝗虫偏光定向响应机制研究和害虫的偏光诱导新光源研制提供理论支撑与技术支持。
To determine the regulation effect of linearly polarized spectrum light with polarization detection vector on the polartaxic response of locusts(Locusta migratoria),the self-made linearly polarized light modulation module and test device for the polarization response of locusts were adopted.The influence of illuminance of linearly polarized spectrum on the polarization response of locusts was also examined to determine the sensitivity mode of locusts.It was shown that the polartaxic response of locusts presented chord function response characteristics to polarization detection vectors with clockwise and anticlockwise direction,and the spectral properties determined the specific sensitivity of locusts.The linearly polarized spectrum intensity affected the sensitive polartaxic vision distance vector of locusts.At 100 lx,the induced polartaxic aggregation response sensitivity of locusts by polarized violet spectrum was stronger,while the induced visual trend sensitivity by polarized ultraviolet spectrum was stronger.At 1000 lx or under the same light energy,the induced polartaxic response sensitivy of locusts by polarized violet spectrum was stronger.With the changes of illuminance of linearly polarized light,the sensitive polartaxic vector mode of locusts was reset:the changes of illuminance of the linearly polarized violet light had enhancement effect,the changes of illuminance of the linearly polarized ultraviolet light had regulatory effect,while the changes of illuminance of the linearly polarized blue,green light had inhibition effect.Moreover,the antagonism sensitivity of locusts to the polarization detection vector(±180°,0°and±90°)was related to the illuminance of the linearly polarized spectrum.The inhibition effect of the weak polarization detection light under±90°,and the reinforcing effect of the strong polarization detection light under±180°and 0°were related to the illuminance or the light distance stimulus of linearly polarized spectrum.At 1000 lx,the polartaxic response sensitivity of locus
