INTEGRATED CONTROL OF CODLING MOTH (CYDIA POMONELLA) IN AUSTRIA

At the beginning of the season, 200 overwintered codling moth (Cydia pomonella) larvae (in cardboard bands) are exposed in a ‘branch cage’ on a tree. Hatched adults are transferred from the branch cage into a egg laying box, a plexiglas tube covered with a polyethylene foil inside. The foil inside the egg laying box can be removed and exchanged, and the number of laid eggs can be counted. Later on, it is possible to watch the development of the eggs on the foil and the hatching of codling moth larvae. This technique gives an overview on the reproductive activity over time on a site and presents more detailed information than pheromone traps alone.

The credibility of data of codling moth activity following branch cage observations was proven in a situation of high Cydia pomonella infestation and two Cydia pomonella generations per year.

Applications of the insect growth regulators, Phosalone and CpGV, resulted in efficient control of codling moth. CpGV applications at two week intervals (starting with hatching of the first Cydia pomonella. larvae) were not satisfactory but applications at weekly intervals were successful.
