%X In this study, crude lantadene was extracted from Lantana canmara leaves, and its antifeeding effects on Plutella xylostella and Spodoptera litura larvae were tested. In no-choice test, crude lantadene at 1.6 mg x ml(-1) concentration had antifeeding effects on the 2nd instar P. xylostella larvae and 1st instar S. litura larvae, with the antifeeding rate being 62.4% and 33.1%, respectively within 48 h. In choice test, even a low concentration (0.4 mg x ml(-1)) crude lantadene still had anti-feeding effects on the 2nd instar P. xylostella larvae, and the antifeeding rate at 0.4, 0.8 and 1.6 mg x ml(-1) concentration was 52.7%, 55.5% and 78.9%, respectively. Crude lantadene only at 1.6 mg x ml(-1) concentration had anti-feeding effects on the 1st instar S. litura larvae, and the antifeeding rate was 33.0%. For the 2nd instar S. litura larvae, crude lantadene had no antifeeding effects both in no-choice and in choice test.
