Navel orangeworm (NOW): Goal is to compare changes in NOW parasitism levels at three critical periods: (i) after the first NOW summer generation (ii) at harvest time, and (iii) during the overwintering period. At each site, a minimum of 1000 nuts will be collected and dissected for NOW or parasitoids. Peach Twig Borer: The peach twig borer adult flight periods will be monitored using pheromone traps. PTB larval infestation will be monitored at three critical periods: (i) during spring (ii) at harvest time, and (iii) during the overwintering period. Nuts will be collected to determine levels of infestation Oriental fruit moth: The oriental fruit moth (OFM) adult flight periods will be monitored using pheromone traps. OFM larvae will be collected to determine infestation levels and parasitism in a similar manner as described for PTB. Leafrollers: Populations of leafrollers including obliquebanded leafroller (OBLR), fruittree leafroller (FTLR), the filbertworm (FW), and omnivorous leafroller (OLR), will be assessed over the next 3 years, in the NOW mating disruption program. The species of moth and their infestation levels will be determined for the three regional areas of the NOW mating program. A color brochure will be developed that provides a picture key, along with some field taxonomy guides, to identify the different secondary moth larvae. A brief description of their biology and control will also be provided.
