The fall armyworm,  Spodoptera frugiperda , is a polyphagous pest that causes important damage in different regions of America and mainly affects corn crops in both tropical and subtropical areas. Currently, control relies on both transgenic plants and/or chemical pesticides. In this work, we describe insecticidal activity against the fall armyworm from a series of Mannich bases ( 1–10 ), derived from 2-hydroxy-1,4-naphthoquinone (lawsone), substituted benzaldehydes, and two primary amines, and their Cu 2+  complexes ( 11–20 ). The [Cu(L) 2 ] complexes were more effective in larval mortality compared to the free Mannich bases. Among the tested compounds, complex  11  showed the highest toxicity, with 70.00% larval mortality.
