Analysis of Tiphia parasitoids preovipositional behaviors and of their scarab host defensive responses.

Highlights: [•] We examine how tiphiid wasps handle Japanese and oriental beetle grubs. [•] We examine the defensive behaviors of scarab grubs. [•] Tiphia vernalis spent longer time trying to sting oriental beetles. [•] Oriental beetles spent longer time on defensive behaviors. [•] Oriental beetle grubs are less susceptible to T. vernalis attack. [ABSTRACT FROM AUTHOR]
