Comparative and synergistic activity of <i>Rosmarinus officinalis</i> L. essential oil constituents against the larvae and an ovarian cell line of the cabbage looper, <i>Trichoplusia ni</i> (Lepidoptera: Noctuidae)

Abstract

Based on our results, the insecticidal activity of rosemary oil appears to be a consequence of the synergistic interaction between 1,8-cineole and (±)-camphor, and (±)-camphor should be considered a promising synergizing agent.
