Abstract

Pheromone traps were used for monitoring phenology of the peach twig borer,Anarsia lineatella, in Central Bohemia. The pest has two generations a year, the first one (owerwintering) is usually more numerous than the second one. The peak of the flight of the first generation begins by day-degrees (DD) 400–450 °C and the peak of the flight of the second generation at DD 900–960 °C. DD data can be used for supervised control both in the case of timing the chemical treatment and for deciding on using pheromones for male confusion. The suitable term for chemical treatment in the given locality in Central Bohemia is DD 360°C (above the developmental threshold 10 °C). The injury to fruits and shoots of peach trees similar to that caused byA. lineatella does also the oriental fruit moth,Cydia molesta. According to very low catches in pheromone trapsC. molesta does not seem to be economically important in Central Bohemia at present.
