Abstract
Crude foliar extracts of 67 species from six subfamilies of Australian Lamiaceae were screened by whole organism contact toxicity on the polyphagous mite Tetranychus urticaeKoch(Acari: Tetranychidae) by using a Potter precision spray tower. Cytotoxicity assessments against insect cell lines from Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) and Drosophila melanogaster (Meigen) (Diptera: Drosophilidae) also were made. The Spodoptera cell line was more susceptible to extracts than the Drosophila cell line.Nodirect correlation was observed between the two screening methods, but several interesting relationships were identiÞed. Extracts from subfamilies Ajugoideae, Scutellarioideae, Chloanthoideae, Viticoideae and Nepetoideae showed acaricidal activity, whereas only those from Ajugoideae and Nepetoideae displayed potent cytotoxic effects. A range of activities was observed for the 25 species of Plectranthus, 14 of which showed moderate-to-high contact toxicity against T. urticae. Overall, the lowest toxicity was observed for extracts from the plant subfamily Prostantheroideae, which showed little contact toxicity or cytotoxicity for the 18 extracts studied.
