The cotton bollworm, Helicoverpa armigera (Hübner), and the beet armyworm, Spodoptera exigua (Hübner), are two major polyphagous lepidopteran pests of cultivated crops. They develop various levels of resistance to many frequently applied broad‐spectrum insecticides. Here, the larval susceptibilities of a laboratory population and six field‐collected populations per pest from Hunan Province, China to three insecticides were determined using a standard leaf‐dipping method in the laboratory. Field‐plot trials were conducted to verify the control efficacies of broflanilide 100 g L⁻¹ suspension concentrate (SC), chlorantraniliprole 5% SC and emamectin benzoate 5.7% water‐dispersible granule, against H. armigera and S. exigua larvae using foliar sprays in 2013 and 2019.
