稻纵卷叶螟计算机管理系统的研究

Studies on Computer Management System of Rice Leaf-roller; Cnaphalocrocis Medinalis Guenee

本系统包括稻纵卷叶螟的预测和资料管理两大子系统:建立了该虫的生长发育、产卵、经济阈值以及种群动态等模型;贮存了29年的气象、成虫种群灯下消长、田间发生和防治、以及常用化学杀虫剂等资料.建立了4个虫情监测点.为本系统提供信息.本系统可以预测稻纵卷叶螟的发生.提供初步管理意见,回答有关卷叶螟及气象方面的资料查询等.它还包括害虫管理常用的9个统计分析应用程序包.

Based on the results of biological and ecological studies on rice leaf—roller, a computer management system of this pest insect was developed.It includes a forecasting sub—system, a data sub—system, a mornitoring Sub—system and a delivery sub—system.This system is able to predict the occurring time of critical events and the density of this pest insect, to provide the primary management suggestion and to answer the questions on rice leaf—roller and meterological information.It also provides 9 programs of statisitics and analysis of data, which can be used in pest management.
