中文摘要： 为了有效的预测害虫的发生期，开发了昆虫发育自动模拟系统，该系统基于网络平台，应用PHP 丰富的函数库和计算功能设计有效积温运算模块，通过公共气象信息系统建立了气象数据库，并根据实时及预报的公共气象信息，即逐日最高及最低气温，昆虫发育有效积温相关的生物学参数，运用正弦法计算每天的有效积温及一段时间的累计积温，自动模拟昆虫在不同时期的发育虫态和虫龄。服务器端基于Apache + PHP + MySQL 架构，操作简单，调试和维护方便。经与2011 年江苏通州烟粉虱Bemisia tabaci( Gennadius)、灰飞虱Laodelphax striatellus( Fallén)系统调查数据比对，符合实际发生情况，可在生产上推广应用。
英文摘要： A web-based auto simulation system for forecasting pest occurrence periods was developed that included an accumulated degree-days calculating module designed by PHP script and a database for public weather information． The system can show information on insect state and larval instar at different periods automatically by integrating the module and the database． The parameters included public weather information，such as the daily maximum and minimum temperature，low and upper temperature thresholds and accumulated degree-days of the insect’s deferent states and instars． These parameters were calculated using a single sine approach． Based on an Apache + PHP + MySQL structure，the system is easy to use and maintain． Data on simulated insect state and larval instars for SBPH and whitefly accorded with actual data on these species collected at Tongzhou，Jiangsu Province in 2011. This consistency suggests that the system has general application．
