Efforts to implement integrated pest management (IPM) strategies and improving our understanding of existing strategies are keys to achieving adequate control of tarnished plant bug, Lygus lineolaris. Insecticide applications are a part of IPM and monitoring their efficacy is critical for producers to remain profitable. Resistance to imidacloprid, thiamethoxam, and sulfoxaflor was documented, although there continues to remain variability among populations within the region. The insect growth regulator, novaluron, although only lethal to nymphs, plays an important role in management of Lygus. Sublethal impacts to adult plant bugs may be an important factor in reducing populations within the growing season. Future research to confirm the validity of using a laboratory colony as a baseline for insecticide susceptibility is needed to account for increased vigor of insects reared on artificial diet.
