摘要
稻飞虱是目前影响中国水稻生产的主要害虫之一。其迁飞行为是生物进化、环境胁迫(特别是食料不足)共同作用的结果,包括起飞、飞行和降落3个阶段,受生理、生态、虫源等多方面因素影响。迁飞过程与天气系统、气象条件、地理特点等因素相关,其中低空急流可以作为监测稻飞虱迁飞的预警参数,与虫情结合可以预测稻飞虱迁入区。迁飞参数化和模型可以较精确地阐明稻飞虱迁出起飞、空中飞行、降落迁入等迁飞行为的动力学机制,模拟其虫源地、飞行高度、迁飞历时、飞行轨迹等,为预防预测稻飞虱提供了科学依据。
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-｜eve1 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.
