Behavioral Effect of The Specific Sex Pheromone PH-227-1RR Towards Butterflies Codling Moth Cydia pomonella in Two Apple Orchards in Draa Ben Khedda Region of North Algeria

Abstract

The study focused on behavioral effect of the specific sex pheromone PH-227-1RR towards butterflies’ codling moth Cydia pomonella L. in apple orchards on 2 different varieties (Anna and Dorset golden) in Draa Ben Khedda region of North Algeria. The results show the existence of two flight periods (2 generations) on the Anna and Dorset golden varieties, overlapping during months from March to July. Flights stopped around early July noted in study area, it appreciably coincides with the harvest of the fruits and with the diapause period of the caterpillars of the last flight. So the appearance of the first generation occurs on variable dates according to the rupture of the diapause and the duration of development of the pupae which depend on climatic conditions.
