 Novaluron has been shown to be highly active against a number of common pests, such as the Colorado potato beetle ("Leptinotarsa decemlineata"), whiteflies, the African Cotton Leafworm ("spodoptera littoralis") and the cotton bollworm.Organisms that are closely related to these animals seem to share this susceptibility to the compound.A notable exception to this is a study evaluating the efficacy of various insecticides on the stem borers "Diatraea saccharalis" and "Eoreuma loftini", in which the results seemed to indicate that these organisms were not susceptible to novaluron.
