Hyposoter didymator uses a combination of passive and active strategies to escape from the Spodoptera frugiperda cellular immune response

► H. didymator relies on passive and active strategies to evade encapsulation by the host. ► Oviposited eggs avoid host encapsulation due to surface proteins. ► Calyx fluid is required for larvae to avoid encapsulation. ► Viral and immune-related proteins appear to be involved in egg immune evasion.
