Abstract. Stink bugs negatively impact numerous plant species of agricultural and horticultural importance. While efforts to develop effective control measures are underway, the unique digestive physiology of these pests presents a significant hurdle for either protein- or nucleotide-based management options. We characterized digestive proteases and nucleases from the gut, salivary gland and saliva of the southern green stink bug, Nezara viridula by using a multidisciplinary approach that includes classical biochemistry, proteomics and transcriptomics. The results from this study, which highlight the challenges associated with application of either Bacillus thuringiensis-derived toxins or RNA interference-based strategies for stink bug management, will be described.
