Dynamics of codling moth larvae (Cydia pomonella L.) in three varieties of apple (Malus domestica Borkh.) in the region of Aït Sbaa (Morocco)

Codling moth (Cydia pomonella L.) is a serious pest of apple in worldwide orchards. Despite their negative impact over the environment, chemical pesticides are the main control method against the codling moth. Cydia pomonella Larvae are responsible of codling moth apple infestations. Thus, the study of codling moth larvae dynamics might contribute to developing alternative codling moth control methods. We studied codling moth larvae dynamics considering canopy aspect (north, east, south, and west) and canopy height (bottom, middle, and top) in three apple varieties in the region of Aït Sbaa (Morocco). First generation codling moth larvae infestation was higher in Golden delicious apple variety. We recorded high second generation codling moth larvae infestation in Royal gala variety. Moreover, first and second generation codling moth larvae infestation was influenced by canopy aspect and canopy height of apple trees belonging to Golden delicious and Starking delicious varieties.
