Overview

Laboratory and semifield trials demonstrate enhanced attraction and oviposition on blueberries in the presence of leaf volatiles, implying a need for better pest control strategies.

Key Points

  • This study aims to understand the role of leaf volatiles in attracting spotted-wing drosophila to blueberries.
  • Laboratory and semifield behavioral assays to test attraction and oviposition rates.
  • Gas chromatography-mass spectrometry used to characterize fruit and leaf volatiles.
  • Electroantennographic assays assessed responses to individual volatile compounds.
  • Adult D. suzukii showed increased attraction to blueberries when accompanied by leaves compared to fruit alone.
  • Oviposition rates were higher in the presence of leaves during choice experiments.
  • Linalool and 6,10,14-trimethyl-2-pentadecanone significantly attracted females and elicited strong EAG responses.
