The Hemiptera are a large and diverse order of insects with mouth parts specially modified for piercing and sucking soluble contents in vascular bundles. Many hemipterans (aphids, whiteflies, psyllids, stinkbugs, leafhopper and planthoppers) are important pests of plants, either by direct feeding and as vectors of viral and bacterial plant diseases. Plants can alter their physiology to tolerate insect infestation and vice versa. Here we present research topics, which include the current and future advances in hemipteran-plant interactions that address the systematics, resistance, susceptibility and implications for future forest research.
