Behavioral and antennal responses of Lobesia botrana (Lepidoptera: Tortricidae) to volatiles from the non-host plant Schinus molle L. (Anacardiaceae)

ABSTRACT Lobesia botrana (Lepidoptera: Tortricidae), the grapevine moth, is one of the major pest on grapes. Current control is based on spraying insecticides and/or mating disruption technique, using female sex pheromone, affecting only adult male’s conduct. Behavioral active compounds as...

(Anacardiaceae)Silva,DiegoCurkovic,TomislavCeballos,Ricardo EAG insect behavior olfactometer plant volatiles ABSTRACT Lobesia botrana (Lepidoptera: Tortricidae), the grapevine moth, is one of the major pest on grapes. Current control is based on spraying insecticides and/or mating disruption technique, using female sex pheromone, affecting only adult male’s conduct.

Through electroantennography (EAG) and olfactory experiments, we investigated the role of volatiles of the non-host plant Schinus molle L. on behavior of L. botrana. Steam distilled essential oil (EO) from S. molle leaves was characterized by gas chromatography coupled to mass spectrometry (GC-MS).
