Objective:
Reduction of unnecessary insecticide application by improving predictability of navel orangeworm abundance and damage.

Approach:
We will examine the association of navel orangeworm damage to Nonpareil almonds, before and during harvest, with trap data. The research will be conducted in organic orchards to minimize grower insecticide input as a confounding factor. Traps examined will include pheromone traps (with unmated females as a pheromone source), and grid traps with ovipositional attractant targeting eggs and females. Association of monitoring with infestation autocorrelation of later infestation with earlier preharvest samples will be examined using generalized linear models.
