This study evaluated the bioinsecticideactivity of organic extracts of Bursera copallifera and B. grandifolia on L1 larvae ofSpodoptera frugiperda. It is likely that theacetonic extract (500 ppm) of leaves of B.copallifera had an effect as an antifeedanton armyworm, causing a 50% reduction inlarval weight at 14 days. It also produced47% larval mortality, whereas the hexaneextract produced 44% deformed pupae, andof the population that emerged from pupae,14% were deformed as adults. Acetone andmethanol extracts of leaves of B. grandifoliaproduced 37 and 45% larval mortality at14 days, respectively, whereas the hexaneextract from stems caused a larval mortalityof 37% over the same period.En este estudio se evaluó la actividad bioinsecticida de...
