Effects of sanitation practices on almond mummies infested with navel orangeworm

摘要: Lab and field evaluations were conducted in order to assess the effect of mowing disking treatments on survival immature stages navel orangeworm (NOW) infesting almond mummies. Flail mower treatments, which included single layers mummies once or twice windrows, resulted 95 99% mortality relative controls. For one two passes a disk 41 89.5% mortality, respectively. In addition, flight peaks delayed up 2 weeks Field imitated lab studies by covering infested nuts with 1 3 inches soil, resulting 9.5 43% mortality. These indicate that is vastly superior for destroying overwintering NOW populations may alter dynamics surviving populations.
