Insecticidal activity of Jatropha gossypifolia L. (Euphorbiaceae) and Cleome viscosa L. (Capparidacae) on Spodoptera litura (Lepidoptera: Noctuidae). Toxicity and carboxylesterase and glutathione-S-transferase activities studies.

The naturally occurring phytocidal chemical components of some Thai plant-species are responsible for controlling and repelling insects from the host plants. The aim of this study was to evaluate the insecticidal activity of Jatropha gossypifolia L. Leaf extracts and the senescent leaf Cleome viscosa L.
