The role of volatile organic compounds in the interactions between leafhopper Arbordiahussaini (Hemiptera: Cicadellidae) and grapevine leaves

Abstract

The leafhopper Arbordiahussaini can seriously destroy grapevines and is susceptible to the infestation of leafhopper. Volatile organic compounds (VOCs) released from uninfested and infested Kamali grape leaves were identified in this study. VOCs released from leaves were collected by the HS-SPME technique and analyzed by GC-MS. The results indicated that the infested leaves produce 19 VOCs; some VOCs were absent in uninfested because of the grape leafhopper infestation. VOCs were different between uninfested and infested leaves. The Olfactometer results showed leafhoppers preferred uninfested and infested leaves compared to filtered air treatment. Moreover, A. hussaini preferred infested leaves compared to uninfested ones. Our findings imply that these variations in VOCs are a crucial mediator in insect-plant interactions and may be employed in future research to pinpoint the primary substances that might be used as a lure for tracking and managing A. hussaini.
