‘Smart’ plants that release volatile defence compounds in response to pest damage, and which recruit beneficial natural enemies, offer an opportunity for exploiting biological control in future crop protection strategies. Using six maize genotypes, Zapalote Chico (‘landrace’), Mirt2A, Sintético Spodoptera (SS), L3, and two commercial hybrids BRS 4103 and BRS 1040, the aim of this work was to evaluate maize responses to larval damage from the fall armywormSpodoptera frugiperda,a major maize pest in Brazil, and the ability of the egg parasitoidTelenomus remusto respond to HIPVs induced byS. frugiperdadamage. Y-tube olfactometer bioassays withT. remusshowed preferential responses to theS. frugiperda-induced volatiles of SS and BRS 4103 compared to constitutive volatiles of the same genotypes, but to none of the other genotypes tested. Chemical analysis of maize volatile extracts showed that SS produced more volatile compounds in response toS. frugiperdadamage, followed by BRS 4103. In addition, higher levels of mono, homo-, or sesquiterpenes, together with green leaf volatiles (GLVs) were the most attractive blend forT. remus;however, there was no attraction when only GLVs were produced in higher levels. In summary, these results show that volatile defence signalling produced by maize plants due toS. frugiperdadamage varies significantly depending on maize genotype and this variability influencesT. remusforaging behaviour.
