The grape vine moth, Lobesia botrana (Denis and Schiffermüller, 1776), a microlepidoptera member of the family Tortricidae, is one of the most important pests that attacks vineyards in Southern Europe and Northern Africa. It is a polyvoltine species with three or four generations per year depending on the latitude. The number of generations is mainly modulated by the temperature and photoperiod but other factors including relative humidity also have an important influence on its development. Temperature and photoperiod operate on the growth rate and the induction of diapause, respectively. L. botrana passes through eight development stages in its cycle: egg, five larval stages, pupa and adult. The efficiency of the control methods (mating disruption with pheromones and chemical treatments) depends on the treatment of pest populations at their most susceptible stages, the prediction of the moth’s development cycle would therefore greatly help in determining an optimal treatment schedule (Moravie et al., 2006). Pheromone traps provide useful information on male moth activity in vineyards, but by themselves, do not provide a reliable basis for timing control methods. However, together with the method of temperature summation, trap samples are important components of phenological models (Riedl et al., 1976) which could be helpful in identifying the peak flight of L.botrana, achieving better timing of treatments. Considering the increasing interest for biorational insecticides where precise timing of treatments is important, daily temperature models could be a useful tool in improving their efficiency (Schmid et al., 1977).
