Interpretive Summary: Leptoglossus species, commonly referred to as leaffooted bugs (LFB), inflict serious damage to a wide variety of hosts. Over the last few years, California agricultural has experienced a marked increase in LFB populations and LFB-related issues in pomegranate, pistachio, and almond orchards. Leptoglossus clypealis, L. occidentalis, and L. zonatus are considered native to California, though L. clypealis and L. zonatus have been reported to be more prevalent in these orchards. Literature regarding Leptoglossus indicates that LFB are capable of vectoring some pathogenic microbes, thus raising questions about related food safety issues. Though pheromones are known for LFB, there is currently no sustainable tool available to growers for control or monitoring of LFB. Ongoing research in our labs has evaluated several California-based host plants of the polyphagous LFB. Using data from the collected headspace volatiles of several surveyed LFB hosts, as well as electrophysiological and field trapping bioassays, our labs seek to formulate and develop a blend of host plant-based volatiles for use as an effective control or monitoring of LFB in pomegranate and tree nut orchards. This chapter provides an overview of the status of semiochemicals used for control of California LFB species.
