Methyl Salicylate (MeSA) could be naturally produced by plants as an herbivore-induced plant volatile (HIPV) for attracting natural enemies as well as inhibiting herbivore populations. This study evaluated the attractiveness of synthetic MeSA lures to the natural enemies and its impact on Eucarazzia elegans (Hemiptera: Aphididae) population as a potential pest in common sage plants (Salvia officinalis L.). MeSA lures were distributed in the experimental fields then sticky yellow traps were used to measure the natural enemy abundances in the treated and untreated blocks. The effect of MeSA on E. elegans population in with and without the absence of natural enemies were conducted in the semi-field while the impacts of MeSA on E. elegans growth were evaluated in the laboratory. According to results, several numbers of natural enemies: Chantaridae, Coccinellidae (Coleoptera), Syrphidae (Diptera), and Chrysopidae (Neuroptera) were abundantly caught on traps adjacent to the MeSA odors. Moreover, the abundance of E. elegans in MeSA-treated blocks was significantly lower than untreated blocks. In semi-field experiments, the aphid populations were significantly reduced on treated common sage plants when it exposed to the natural enemies in the 2nd and 3rd week after MeSA deployment. In laboratory condition, the aphid growth rates undertreated and untreated were not different implicating no effects of MeSA on aphid population and emphasizing the role of natural enemies in the aphid control.
