Aqueous and organic (hexane, chloroform, and methanol) extracts of siliquae, stems and leaves, and seeds of  Cleome arabica  L. (Brassicales: Capparidaceae) were evaluated in the laboratory for their antifeeding and insecticidal effect on larvae of the cotton leafworm,  Spodoptera littoralis  (Boisduval) (Lepidoptera, Noctuidae), using a leaf dipping bioassay with castor bean,  Ricinus communis  L. (Malpighiales: Euphorbiaceae), leaf discs. The polar extracts caused significant mortality. At the highest dose,  C. arabica  extracts exhibited significant antifeeding and phagostimulating activities against  S. littoralis  larvae. Under no-choice conditions, the methanol extract of siliquae was the most active, and the antifeedant index calculated over 24 hr for 3rd instar larvae varied significantly from 16 to 37%. Using nutritional indices, it was established that there was a significant decrease in growth rate concomitant with a reduction in consumption. These results suggest the presence of anti-feeding and/or toxic substances in the extracts that may be useful in developing bio-insecticides based on  C. arabica  extracts for use in integrated pest management of leafworm and other agricultural pests.
