Mathematical Evaluation of Locust′s Phototacticag Gregation Effect Stimulated by Light-temperature-sound-vibration Cupling

In view of the superposition of light-temperature-sound-vibration coupling energy stimulating locust′s phototaxis，on the basis of effect areaacting on locust，utilizing the mathematical modelestablished by light-temperature-sound-vibrationstimulating locust′s phototactic aggregation，the gain and efficiency effect of locust′s phototactic aggregation stimulated by light-temperature-sound-vibration coupling was assessed and analyzed by math.The results suggested that light field mechanism plays a leading role on locust′s phototactic aggregation，the regulated mechanism of light field and non-light physicalmechanism play the role of driven stimulation and gain efficiency，the coupling effect of light and physical source can regulate and stimulate locust′s phototactic aggregation effectively，while the intensity of locust′s sensitive energy，determines the stimulation effect of locust′s phototactic effect，combining the working mode of light source′s regulative illumination and physical stimulus source stimulating locust effectively，and adding physical disturbance stimulus measuresregulating and stimulating locust′s phototaxis，can enhancelocust′s phototactic aggregation effect.
