Abstract:

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.
