Insights into the saliva of the brown marmorated stink bug Halyomorpha halys (Hemiptera: Pentatomidae).

ABSTRACT: We examined the salivary gland structure of the brown marmorated stink bug (Pentatomidae: Halyomorpha halys) and developed methods for independent collection of watery saliva and sheath saliva. This stink bug has become a serious invasive pest of agriculture in the United States and its saliva is largely responsible for the damage it causes. We determined by protein gel analysis and shotgun proteomics that the suite of proteins comprising the sheath and watery saliva are very distinct. Our results indicate that a substantial amount of sheath proteins are derived from tomato when stink bugs feed on tomato fruit. Consequently, the sheath saliva is comprised of both insect and plant-derived proteins. Both sheath and watery saliva possessed amylase activities, but polyphenol oxidase and glucos
