Characterization of Volatile Compounds from Tea Plants (Camellia sinensis (L.) Kuntze) and the Effect of Identified Compounds on Empoasca flavescens Behavior

The tea green leafhopper, Empoasca flavescens, is a major pest of Camellia sinensis (L.) Kuntze. Until recently, it has mainly been controlled by pesticides, but their use led to high levels toxic residues in plants, which threaten both the environment and human health. Therefore, safer biological control approach needed. Tea plants produce many volatile compounds, different clones differ resistance pest. We explored possibility that compounds influence tea. Here, we assessed 15 pest, produced clones, effects on E. flavescens behavior. Six were classified as resistant, eight moderately susceptible, one susceptible. Fresh leaf samples from resistant susceptible analyzed using HS–SPME–GC–MS. Sesquiterpenes monoterpenes two groups characterized, representing 30.15% 26.98% total respectively. From our analysis, conclude 3-hexen-1-ol, 2,6-dimethyleneoct-7-en-3-one, humulene, β-bourbonene, styrene, benzaldehyde important for susceptibility clones. In bioassay, attracted β-ocimene methyl salicylate, avoided linalool compounds.
