Stilbenes could be involved in the interference of the sclerotization and moulting properties, and appear to have selective effects on the pre-emergence metabolism of the insect. The methanol extract from the bark of Yucca periculosa F. Baker afforded 4,4′-dihydroxstilbene, resveratrol and 3,3′,5,5′-tetrahydroxy-4-methoxystilbene and had growth regulatory activity against the Fall Army worm ( Spodoptera frugiperda J.E. Smith, Lepidoptera:Noctuidae) an insect pest of corn. The most active compound was 3,3′,5,5′-tetrahydroxy-4-methoxystilbene which had significant effects at 3 μg/g in diets. In addition to the inhibitory activity on bleaching of crocin induced by alkoxyl radicals, these compounds also demonstrated scavenging properties toward 2,2-diphenyl-1-picrylhydrazyl in TLC autographic and spectrophotometric assays. Our results indicate that these compounds could be involved in interference of sclerotization and moulting. These compounds appear to have selective effects on the pre-emergence metabolism of the insect. The results were fully comparable to known natural insect growth inhibitors such as gedunin and Cedrela extracts and have had a possible role as natural insecticidal agents.
