Abstract Background The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is a highly polyphagous and destructive pest of maize other cereal crops. Biological control potential alternative to chemical insecticides used for the management FAW in maize. Egg parasitoids are promising biocontrol agents as they kill insect at their egg stage before it hatches, thus preventing damaging larval stage. Trichogramma widely augmentative biological native invaded regions. However, lay masses layer by eggs covered with scales, this may affect performance parasitoids. Therefore, parasitism three species was studied on or without scales layered FAW, further impact ovipositor length also determined. This helps understand different type better implementation programs against FAW.
