Essential oils from 14 species of Labiatae were steam-distilled and analyzed. Bean leaf discs freshly sprayed with different concentrations of the acetonic solutions of the oils caused mortality and induced repellency in adult females of the carmine spider mite, Tetranychus cinnabarinus (Boisd.), and egg-laying was reduced. Seven-day-old residues still had some activity. On the basis of EC-50s, the most effective oils were: Lavandula angustifolia x L. latifolia (0.09%); L. angustifolia (0.1%); Melissa officinalis (0.12%); Mentha piperata (1.3%); Salvia fruticosa (1.4%); Ocimum basilicum (1.4%); and Rosmarinus officinalis (2.2%). © 1986, Springer Science + Business Media B.V..
