Two years ago, the computer program entomoLOGIC 1 was first made widely available to cotton growers and consultants. It was designed to assist in management of insect pests on cotton through the use of models of crop and pest development and other technology including a valuable record keeping capability. These functions serve a common purpose; better decisions can be made with the experience and understanding gained by good records of what has occurred in the past, and good reporting of what is currently happening on the farm. The models and other new technology can then assist in analysing the immediate crop and pest situation
