%X A growth and development simulation medel of plastic-covered tomato, and aforaging structure model of tomato fruitworms, Heiccoerpo armtw (Hubner), have beenestablished based on field experimental data of 1993 and 1994. Net photosynthesis rate, drymatter accumulating of each plant orgen, construction of morphology and product yielding arepredicted. The causes of shedding of the bud, flower and fruit are summed up as physiologicaldrop, bad enviroment conditions and pest damage, and fuly analysed so that they can be con-veniently coupled with the tomato fruitworm foraging model.The quantities and the components of the tomato reproductive organs (bud, flower andfruit)damaged by the fruitworms in different instars of the 1st and 2nd generations are de-scribed in the fruitworm foraging model. The foraging behavior changes in accordance with thedevelopmental stages of the tomato plant in different seasons. Under the field experimentalcondition, exceeded, completed and partial compensation are observed respectively, whensome tomato buds, flowers and small fruits are damaged by fruitworms. Compensation coeffi-cients are set in the model to reveal the plant's capacity of compensation.Used as an interface, the fruitworm foraging model can link the tomato simulation modeland the tomato fruitworm population dynamic medel to establish a tomato-pest managementsystem.
