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。
In order to effectively predict the occurrence of pests, an automatic insect development simulation system was developed. Based on the network platform, this system designed an effective accumulated temperature calculation module by using PHP’s rich library of functions and computational functions. The meteorological database was established through the public meteorological information system. Real-time and forecasting public meteorological information, that is, the maximum and minimum daily sunshine temperature and the effective accumulated temperature of insects, using the sine method to calculate the effective daily accumulated temperature and the accumulative accumulated temperature over a period of time, and automatically simulating the insect development in different stages And worm age. Server-side based on Apache + PHP + MySQL architecture, simple operation, easy debugging and maintenance. Comparing with the survey data of Bemisia tabaci (Gennadius) and Laodelphax striatellus (Fallén) in Jiangsu Province in 2011, it accords with the actual situation and can be popularized and applied in production.
