With the aim to definite the visual sensitivity selection difference of locusts biological response inspired by the visual excitation effect of spectral and polarized light, and determine the visual excitation factor and the visual sensitivity information of locusts phototactic and polartactic selection, based on the investigated experiment of swarm locusts biological selection effect responding to spectral light and polarized light respectively, the visual regulating function of locusts phototactic and polartactic selection disparity, the visual sensitivity factors and the visual exciting intensity of locusts stimulated by spectral light and polarized light were analyzed. Results show that locusts light aggregation degree induced by the superimposition function of spectral and spectral polarized light presented the sensitivity difference of physiological response to the regulation of polarized light vector, but when light stimulus intensity increased, the sensitive polarization vector of locusts visual response orientation changed, and the photosensitive biology aggregation response effect stimulated by the coupling light stimulation effect of 210°, 120° vector of violet polarized light and violet light, 210° vector of orange polarized light and orange light was the better, while that of 270° vector of violet polarized light and violet light was the worst. Locusts visual light selectivity with the visual excitation state tended to polarized light with the weaker stimulation intensity, spectral light stimulation intensity and polarized light vector sensitive degree weakened locusts positioning control behavior, and locusts polartactic vision sensitivity inspired by UV and violet polarization vector was the stronger while blue and orange polarization vector was the weaker, but 90°, 270° vector of polarized light made the stimulation effect of spectral light dominate light selectivity intensity. Moreover, the enhanced degree of locust visual sensitivity selection to violet polarized light, 120° vector of UV polarized light caused by the increment of the stimulating intensity was the stronger and the weaker respectively, and the weakened degree of spectral light selectivity caused by 90° vector of blue polarized light was the stronger. Thus, the aggregation difference of locusts response to spectral light coupling with polarized light and the selection intensity difference between spectral light and polarized light, originated from the regulated output effect of light reaction synergistically or antagonistically generated by the incentive of polarized light vector and the stimulation of spectral light, and spectral light intensity could weaken the intensity of selection to polarization vector information, but locusts bio-photosensitive response and spectral light sensitivity presented significant correlation, and the light gradient of spectral light coupling with polarized light, significantly affected locusts sensitive response intensity, while light stimulation intensity effect was not significant. Research results provide theoretical support for the manufacture of the agricultural pest induction machinery product and locusts visual response mechanism.
