The potential of irrigated cover crops as a management tool for stink bugs in organic pistachios

A complex of stink bugs and leaffooted bugs causes significant damage on California nut crops like pistachios, especially in organic production where pest control options are limited. Using a novel irrigation system, we investigated the potential of ten cover crop species on the abundance and composition of this pest complex and their natural enemies. We followed pest populations from beginning of May until harvest at the end of September using beat and sweep samples as well as surveying stink bug and leaffooted bug oviposition and plant phenology. The identification of cover crop species that are well-suited for this agroecosystem and draw stink bugs and leaffooted bugs from the pistachio canopy can add to the IPM toolbox, be used in combination with biological or chemical control and facilitate an increase in marketable nuts.
