本文将太湖单季晚稻区褐飞虱数量动态预测模型设计成在SHARP PC-1500和CAS10 PB-700两种袖珍微机上使用的BASIC语言程序,并介绍其操作过程。该程序以田间种群稳定增长始期的虫量为计算起点,结合历年气温资料和水稻生育期,即可连续输出10月上、中旬之前每3天1次的田间各虫态、虫龄数量的预测值。 In this paper, the dynamic prediction model of Nilaparvata lugens (Nilaparvata lugens) in the single cropping rice area of ​​Taihu Lake was designed as BASIC language program which is used on two compact microcomputers SHARP PC-1500 and CAS10 PB-700, and its operation process was introduced. The program starts with the amount of insects in the stable population growth period as the starting point. Combining with the temperature data and rice growth period in the past years, we can continuously output the prediction of insect population and insect population in the field once every three days before the mid-October in October value.
