The study of the chemical ecology of insects led to the development of efficient and sustainable pest management techniques using semiochemicals. One of these methods is the attract-and-kill, that consists of attracting the insect to a lure in combining with an insecticide that kills the insect. Here, we assessed the efficacy of the plant-based attractant NOCTOVI® as an attract-and-kill method against noctuid corn pests, mainly Spodoptera frugiperda and Helicoverpa spp., when used together with 2% of the insecticide methomyl. The product was hand sprayed in a linear range of 92m in every treated portion of a commercial corn crop. The total mean amount of S. frugiperda males collected in pheromone traps was higher in areas without application than in areas with NOCTOVI® and with the NOCTOVI® + methomyl mixture. The density of Helicoverpa spp. males was not different between the treatments. Dead moths from the families Noctuidae and Erebidae were found only in the areas treated with the insecticide, most of them being S. frugiperda. It was observed no mortality of non-target organisms. The mixture of NOCTOVI® and methomyl proved to be suitable for use as attract-and-kill, evidenced by fewer males of S. frugiperda being caught in this treatment than in control one. Thus, NOCTOVI® is shown to be a promising product for S. frugiperda and other noctuid corn pests control.
