Abstract: In 9 years of the period 1993-1999 and 2001-2003 the flight activity of Archips podana was investigated by pheromone traps placed in four apple orchards in Central and East Bohemia. The cumulative catches of A. podana males were plotted against time of the catch expressed in sum of degree-days (DD) above 10°C and approximated by Richards' function. Common parameters of Richards' function could be found for the overwintering generation of A. podana from all localities. The beginning, peak and end of flight activity of the overwintering generation of the A. podana population in Central and East Bohemia can be predicted by use of DD. Archips podana is usually bivoltine in the Czech Republic, rarely univoltine in cold years or cold localities. Construct the flight pattern of the summer generation could of A. podana not be constructed, because the course of flight of this generation in dependence on DD differed significantly in particular years and localities.
