Short summary
The generalist parasitoid wasp Meteorus pulchricornis shows an innate preference for Spodoptera frugiperda over Plodia interpunctella, driven by distinct volatile organic compounds. Olfactory receptor co-receptor (MpulORco) knockdown impairs this preference, and wasps reared on S. frugiperda exhibit greater body size and fecundity.
