| Abstract:
An experiment was done to compare the effect of using a supervised control program based on pheromone trap catches with a preventative spray program on the number of sprays per season for codling moth, Cydia pomonella L., control in Syria. In the preventative spray program, insecticides were applied every 2 –3 weeks starting at 90 % petal fall whereas in supervised control program, insecticides were applied when a critical catch level was reached (5 months or more/trap/week for 2 consecutive weeks). The results showed that insecticide application based on trap catch resulted in a significant reduction in the number of treatments when compared to the preventative spray program. The number of post bloom sprays for the preventative spray program was 6 sprays per season while the number of sprays for the supervised control program was only 2. Although percentage fruit infestation caused by codling moth was higher in the orchard where chemicals were applied according to trap catch data, the difference was not significant and percentage infestation under both programs was less than 1%. | |
