Morphological defense of the egg mass of Spodoptera frugiperda (Lepidoptera: Noctuidae) affects parasitic capacity and alters behaviors of egg parasitoid wasps

•Te. remus showed the greatest aggression towards S. frugiperda eggs masses.•PParasitism rate ofby Te. remus was higher than that ofby Tr. dendrolimi or Tr. pretiosum.•Parasitism efficacy was higher in Tr. pretiosumT. remus than Tr. dendrolimiT. pretiosum in S. frugiperda eggs.•Our findings have implications for augmentative biological control of S. frugiperda.
