农作物的主要害虫常年对作物造成严重危害，使农业经济遭受严重损失。根据害虫的发生、发展规律，以及作物的物侯和气象预报等资料，进行全面分析，作出其未来的发生期、发生量和危害程度等估计，预测害虫的未来发展动态，这项工作就叫做农作物虫情预测。-The main perennial crops on crop pests cause serious harm to the agricultural economy suffered serious losses. According to pest oc

农作物虫情预测。BP神经网络具有对非线性复杂系统预测的良好特性，可以有效地描述其本身具有的不确定、多输入等复杂的非线性特性。-Prediction of crop pests. BP neural network has the good characteristics of nonlinear complex systems, prediction, can effectively describe the complex non-linear characteristics of the i
