Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) eggs as alternative food for rearing of lady beetles Eriopis connexa (Germar) (Coleoptera: Coccinellidae)

► Difficulties in mass rearing can limit researches with Coccinellidae predators. ► Eriopis connexa was fed with eggs fresh, previously frozen and with or without scales or recent-hatched Spodoptera frugiperda caterpillars. ► The high survival of E. connexa fed eggs of S. frugiperda shows the potential of this prey to mass rear this predator.
