Technical Abstract: California produces 100% of the U.S. market’s supply and ca. 80% of the world’s requirements for almonds. The ex situ and in situ collection analyses have been performed on single almond cultivars but are not representative of the bouquet of volatiles emitted by the combination of cultivars found in almond orchards. Additionally, California is the second largest cultivator of pistachios, producing 90% of the U.S. supply. Despite the agricultural and economic importance of pistachios, little is known regarding their actual volatile emissions. Investigations have suggested certain volatiles from almonds exhibit semiochemical characteristics for the navel orangeworm (NOW), a major insect pest of almond and pistachios. Recent ambient orchard volatile collections show several similarities between almond and pistachio orchard emissions. Correspondingly knowledge of the semiochemical medium of these orchards would be beneficial to NOW kairomone research. Almond and pistachio ambient orchard volatiles are of interest owing to their potential roles as semiochemicals to NOW.
