Management of navel orangeworm and ants

Abstract Not Available – First paragraph follows: Orchard cover crops are generally thought to be beneficial in the management of pests, especially certain insects and mites. Depending on how they are manipulated, however, cover crops have the potential to increase damage from some pests. If cover crops are not managed correctly-for example, are mowed at the wrong time or are under stress for moisture-plant-feeding insects may move from the orchard floor into the trees to feed on developing fruit.
