Los extractos de neem (Azadirachta indica) y sus ingredientes activos como la azadiractina, presentan acción antialimentaria e inhibición del desarrollo de muchos insectos. El objetivo de este estudio fue examinar el efecto antialimentario de los extractos de suspensiones celulares de neem elicitadas a diferentes condiciones de luz y temperatura. Los extractos fueron aplicados en discos de hojas de maíz y sometidas a bioensayos en larvas de segundo instar de Spodoptera frugiperda J. E. Smith (Lepidptera: Noctuidae). Los extractos intracelulares y del medio de cultivo de las suspensiones celulares de A. indica mostraron efecto biológico sobre larvas de S. frugiperda L2, con valores del 100 % de índice antialimentario para los extractos intracelulares de suspensiones de A. indica elicitadas a 15 °C y oscuridad, y del 39,3% para extractos extracelulares (medio de cultivo) de suspensiones elicitadas a 35 °C y oscuridad.
