In 1994 Egypt will use artificial pheromones for pink bollworm control on 150,000 ha of cotton, 45% of the national crop.  The COT plant and insect simulation model has been initialised for the main long staple cotton varieties (Giza'75 and Giza'80) and for the release rate characteristics of several pheromone formulations and dispenser types.  When primed with the magnitude of the spring bollworm emergence and certain agronomic data, the system will generate plant and bollworm populations for given field management scenarios.  Simulations have proved accurate and useful but have demonstrated problems with the use of pheromone traps as control decision tools.  The Ministry of Agriculture intends to use the model to schedule pink bollworm pheromone and insecticide applications on significant areas of commercial cotton in forthcoming seasons.
