The main volatile components of leaf extracts from Lantana camara by gas chromatography–mass spectrometry (GC-MS) were identified as β–caryophyllene (29.67%), caryophyllene oxide (2.69%), α–humulene (10.24%) and germacrene D (1.72%). The antifeedant activity of Lantana camara essential oil was tested against Spodoptera litura and Plutella xylostella at different concentrations. Results indicated that 50%-60% antifeedant activity induced by the oil was recorded on Spodoptera litura and Plutella xylostella second instar larvae and gave significant difference compared to the control (P=0.0000) in no-choice test and choice-test experiments, respectively; the essential oil of Lantana camara affected the ratio of pupation and adult emergence of both S. litura and P. xylostella.
