偏振波谱光态矢量光照参量对东亚飞蝗偏光响应效应的影响

为明确偏振波谱光态光照参量对蝗虫趋偏响应效应的影响作用,获取蝗虫偏振诱导光场的技术特征,研制蝗虫偏振诱导光源,利用蝗虫偏光响应试验装置测试了蝗虫对紫、蓝部分偏光及线偏光的响应特征,以此优选波谱偏振光态矢量的作用模式,分析偏振波谱光态光照参量对蝗虫偏光响应机制的影响,探讨蝗虫偏光波谱矢量敏感模式变化的原因。结果表明,部分偏光中,紫波谱未引起而蓝波谱导致蝗虫视响应与视趋性敏感矢量发生改变;线偏光中,紫、蓝波谱均影响蝗虫趋偏响应效应的矢量敏感模式,且波谱相同,部分偏光矢量置向模式对蝗虫的操控诱导、视趋强度的调控性优于线偏光,而偏振矢量光态相同,紫波谱的作用效果强于蓝波谱。蝗虫趋偏响应效应与偏振波谱、偏振光态的异质作用效应有关,且线偏紫波谱120°左右置向矢量对蝗虫的诱导效果最强(94.5%),而紫波谱部分偏光左60°及右150°矢量对蝗虫视趋强度的作用效果最强(68.5%);部分偏光矢量置向模式的作用效果与波谱光致性视敏偏振效应有关,且蓝波谱中偏振度越高而光照度越低,矢量模式的操控诱导性越强,紫波谱中偏振度越低而光照度越强,矢量模式对蝗虫趋偏聚集程度的作用效果越强。从而,线偏与部分偏光不同矢量光照交替刺激模式可提高蝗虫趋偏响应敏感性。

Influence of polarized vector mode of polarization spectrum light state on polarized response effect of Locusta migratoria

To clear the function effect of spectral polarized light state parameter on locusts polarized response effect, and obtain the technical characteristics of locusts polarization induction light field for manufacturing locusts polarization induction photo-source, utilizing locusts polarized light response test device, locusts response characteristics to partially and linearly polarized light with violet, blue spectrum, and the vector action mode of polarized light state was optimized to analyze the influence mechanism of polarized spectrum light state parameter on locusts polarized response effect, and discuss the reason for the sensitive change of locusts spectral polarized vector mode. Results showed that in partially polarized light, violet spectrum did not while blue spectrum caused the change of the sensitive vector, while in linearly polarized light, violet and blue spectrum all affected locusts sensitive vector mode, and under the same spectrum, locusts control induction effect, and polartaxic intensity caused by the vector directionality mode of partial polarized light were better than that of linearly polarized light, but under the same polarization vector light state, the function effect of violet spectrum was better than blue spectrum. Then, locusts polarized response effect were related to the heterogeneous initiation effect of polarized spectrum, and polarized light state, and locusts control induction effect caused by left and right 120° vector of linearly polarized violet light was the strongest (94.5%), while the function effect of locusts polartaxic aggregation degree stimulated by left 60° and right 150° vectors of partially polarized violet light was the strongest (68.5%). The effect of partial polarization vector orientation mode is related to the spectral photo-induced visual sensitivity polarization effect, and the higher the degree of polarization in the blue spectrum and the lower the illumination, the stronger the manipulation inducement of vector mode; the lower the degree of polarization in the purple spectrum and the stronger the illumination, the stronger the effect of vector mode on the degree of bias aggregation of locusts. Thus, the vector light alternating stimulation mode with different linear polarization and partial polarization can improve the sensitivity of locust's bias response.
