Studies of Overwintering Codling Moth Infestation of Harvest Bins

摘要: Codling moth (Cydia pomonella) have long been suspected of emerging from stacks harvest bins in the spring and causing damage to nearby apple pear orchards. With increased use mating disruption for codling control, outside sources infestation become more a concern growers using pheromone confusion systems. Studies were designed provide information on source larvae infesting (what proportion infested fruit placed vs. entering before is picked) pattern emergence bin piles. In these studies, (CM) colonized wood at much higher frequency than made injection molded plastic (189 moths emerged 5 plastic). There was no statistical difference number that had filled with compared left empty harvest. This suggests CM enter during time spent orchard Emergence adult 216 (6 wide by 6 deep high) found be prolonged over field populations. Temperature differences within account this attenuated pattern. could important developing technique neutralizing understanding how may influencing pest management orchards receive large piles or are located near Implications control conventional those as principal component an IPM system discussed.
