The pistachio industry in California is located primarily in the San Joaquin Valley, which accounts for 97% of the production in the U.S (CPRB 2009). The city of Fresno is centrally located favorable for the growing season because it is typically hot and dry; daytime temperatures commonly exceeding 100 degrees F. and rainfall between May and October is effectively absent. Because pistachio trees typically bloom in mid April, monitoring for pests is best suitable in early spring.
A most common pest that can damage Pistachio crops are Navel orange worms because they damage pistachios by predisposing nuts to contamination by fungal organisms that produce aflatoxins (UCIPM 2015). The first and second navel orangeworm generations should be done
