Abstract:   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.
