The computer based decision support system, entomoLOGIC was first developed five years ago as a basic prototype. The first release of the DOS version for commercial use was at the Cotton Conference in 1992. This program was developed and improved over the next 3 years and has been widely used by cotton growers and agronomists. Following much feedback from users, entomoLOGIC was completely rewritten in a Windows environment and released as entomoLOGIC 95 for the 1995/96 season. entomoLOGIC 95 was easier to use and also more capable than the DOS version. As well as insect management technology, it incorporates a field and crop history system which allows growers to record all production activities
