Abstract: The Rice Planthopper was one of the main insect pests in rice production in China at present. The long-distance migration, which including take-off, flight and landing was the results of biological evolution and environmental stress, especially the food shortage, which affected by physiological station, ecological situation, insect source and other factors. Weather system, Meteorological factors, geographic features, and other factors were related to migration progress, in which the low-level jet stream could be used as monitoring migration of rice Planthopper in warning parameters, combined with the sources of Rice Planthoppers to predicted the landing-area. Migration parameter and model could accurately elucidate the rice Planthopper from take-off, flight, landing immigration of migratory behavior dynamics, simulation from the insect source, flying height, flight time, flight trajectory, to provide scientific basis for prevention of rice Planthopper.
