Abstract

Stink bugs are one of the highest-risk pests for soybean. These insects feed directly on pods, affecting grains, and thus seriously affecting seed yield, physiological and sanitary quality. Among the most prominent phytophagous pentatomid species are Euschistus heros (Fabricius), Nezara viridula (Linnaeus) and Piezodorus guildinii (Westwood), these three insects make up the so-called soybean "stink bug complex". We hypothesize that these symptoms, along with reductions in crop growth rate and other developmental indicators, can be assessed with high-resolution RGB imaging using UAS. We believe that, once established, high-throughput phenotyping of insect resistance will provide quantitative phenotypes from multiple environments. In combination with genomic data, new loci controlling resistance may be identified, or insights may be provided to existing loci, and/or genomic prediction equations incorporating growth curves can be developed.
