Predictive value of a model of the flight activity of Adoxophyes orana (Lep.: Tortricidae)
Journal of Pest Science 78 (4), 205-211
Abstract: In 1992-2002, the flight activity of Adoxophyes orana (AO) was investigated using pheromone traps placed in apple orchards in five localities in Central and Eastern Bohemia. The cumulative catches of AO were plotted against time expressed as the sum of day-degrees (D°) above 8°C and approximated by a Richards' function. This model was constructed using the numbers of AO males caught by pheromone traps from 1992-1998 at all the localities. The flight of the overwintering generation of AO began when 200 D° had accumulated, culminated at 300 D° and ceased at 430 D°, irrespective of locality. The high predictive ability of the model was validated using data from one locality for 2001-2003. It was impossible to construct a similar model to predict the flight activity of the summer generation because its dependence on D° varied greatly between localities and years.
