Abstract:To determine the visual response effect of locust inspired by different light properties of blue light, and obtain the stimulating mechanism and the polarized light induction information for locust to manufacture locust induction light source, based on the investigated experiment of swarm locusts visual stimulation response to different blue light properties, the physical characteristics of light energy required by locusts phototaxis and polarotaxis response were analyzed to obtain the influencing factors of light wave information. The results showed that the polarization effect of linearly polarized blue light determined the vector sensitivity of locusts visual response degree and linear polarized illumination restricted locusts visual tendency intensity and visual aggregation effect, and the visual stimulation of linear polarized light quality formed by polarizer in the weaker blue light was better, while depolarized blue light intensity decided the visual stimulation of locusts visual tendency intensity and the visual sensitivity of locusts visual aggregation effect, polarization degree and E-vector illumination presented the interaction effect intensifying or inhibiting locusts sensitive response to depolarized blue light. Meanwhile, enhancing the linear polarized and depolarized illumination inhibited locusts visual aggregation effect for the stronger depolarized illumination, emerging vector sensitive response difference of polarized E-vector, the visual response degree of the weaker linear polarized light and depolarized 0° vector light was superior, and the coupling vertical streaks with polarized light were used to intensify the stimulation of polarized light information and lower the polarized light illumination optimizing polarized light induction information, which was relative to 100lx polarized light, incited the change of the sensitive E-vector, and its 120° vector sensitivity was stronger, but when illumination was 10lx, visual tendency intensity and visual aggregation effect of 330° depolarized light was optimal. Moreover, locusts visual tendency intensity and visual aggregation effect of depolarized light had positive and negative correlation with polarization degree along with visual stimulation information, and polarized light illumination respectively, and locust visual response effect on 10lx polarized light presented the change law of sine and cosine functions response to vector change, indicating locusts had E-vector polarization response pattern and vector function with the maximum activation of visual polarization nerve, and then the coupling effect of 30° and 330° of 10lx depolarized blue light and 100lx linear polarized light or 0° of 10lx depolarized blue light were utilized to improve locusts visual response effect effectively.
