%X Emulsifiable concentrate (EC) formulations pose an environmental risk due to the presence of toxic solvents such as xylene, and safer and more effective nanoformulations can be useful in developing new pest management methods. In this study, a 2.5% deltamethrin nanoformulation was prepared and its size, shape, and active ingredient content were confirmed using SEM, AFM, DLS, and TGA methods. Then, this nanoformulation was compared with a commercial pesticide for controlling wheat in the stages of wintering adults, fourth-instar nymphs, and a new generation. Treatments included deltamethrin nanoformulation, nanocarrier, deltamethrin EC 2.5%, and water as a control. The nanoformulation maintained its insecticidal effect well (73%) in vitro after 45 days, but the mortality rate in the commercial EC formulation was very low (13%). In greenhouse evaluations, this formulation at a concentration of 125 mg/L produced over 90% mortality against overwintered adults. Nymph mortality was also reduced to 40% after 45 days of spraying.
