Resumo(s)
A conceptual model is proposed as a decision tool for control of European grape moth Lobesia botrana Denis & Scchiffermuller (Lepidoptera; Tortricidae) in the "vinhos verdes" region in the northwest of Portugal. The aim is to use simple methods of estimating the pest population so the farmers can make future decisions earlier in the season and avoid the effects of a third generation. A dochotomous decision tree was used to structure the alternative choices by each farmer. For the tree L. botrana generations, generation by generation, the most user friendly and adapted estimates were selected. The model can be formatted in an Excell algorithm and can be easily copied for use in the entire region. With further information on the susceptibility of different grape variety to L. botrana - this model should be adaptable for progressive elaboration and refinement. By using local observations and decision thresholds the model can be extended to other regions
