Abstract

Brown marmorated stink bug, Halyomorpha halys (Stål), is an invasive species in the United States that attacks a wide variety of agricultural commodities including fruits, vegetables, agronomic crops, and ornamental plants. Populations of H. halys adults were collected from four and six states in 2017 and 2018, respectively, and tested using topical applications to establish baseline levels of susceptibility to two commonly used insecticides, bifenthrin and thiamethoxam. A Probit-estimated (95% fiducial limits) LD 50 and LD 99 of 2.64 g AI/L (1.2-3.84 g AI/L) and 84.96 g AI/L (35.76-716.16 g AI/L) for bifenthrin, and a LD 50 and LD 99 of 0.05 g AI/liter (1.14E-5-0.27 g AI/L) and 150.11 g AI/L (27.35-761,867 g AI/L) for thiamethoxam, respectively. These baseline levels can be used for future insecticide resistance monitoring in H. halys.
