摘　　要：This study investigated the influence of different linearly polarized spectrum lights on locusts polartactic response characteristics linearly polarized vector sensitivity mode and polartactic response by using linearly polarized spectrum vector light module and experimental device.The objective was to clarify the vector sensitivity characteristics and functional effect of linearly polarized light spectrum intensity on locusts polartactic response,determine the influence specificity of linearly polarized spectrum illumination properties on locusts polarization-related behavior.When spectrum and illumination were constant,locusts polartactic response,presenting the response feature of sine and cosine function change specificity,was related to spectrum attribute.The visual acuity effect stimulated by violet spectrum was the best,whereas the optical distance modulation effect induced by orange spectrum was the strongest.When illumination was enhanced,locusts vector sensitivity mode shifted to present the specific sensitivity prompted by light intensity at long distance and inhibited by light intensity at short distance.Moreover,the regulating function of violet spectrum was the strongest,and the regulatory mutation effect of orange spectrum was the least significant.Simultaneously,locusts polartactic sensitivity to 300°vector at 100 lx,whereas to 240°vector at 1000 lx of linearly polarized violet light was the strongest.Locusts polartactic aggregation and visual tendency sensitivity to 90°vector at 100 lx,whereas to 270°vector at 1000 lx of linearly polarized violet light was the strongest.The heterogeneous regulation function of different linearly polarized spectrum couplings with light intensity led to significant variations in locusts vector sensitivity mode.This was derived from the antagonistic and specific tuning characteristics of locusts polartactic vision,reflecting the integrated output effect of locusts vector dependence regulated by linearly polarized spectrum intensity attribute.The findings were si
