Concise synthesis of an antifeedant sesquiterpene against Locusta migratoria.

Inhibition of Oogenesis and Ovarian Ecdysteroid Synthesis by Azadirachtin in Locusta migratoria migratorioides (R. & F.)

Locusta migratoria, Azadirachta indica, Ecdysteroids, Azadirachtin, Ovary The sterilizing effect of azadirachtin, an insect growth regulator from the neem tree, Azadirachta indica A. Juss, was tested with mature females of Locusta migratoria. After a single injection of 10 |ig into females between 2 and 13 days after emergence, about 60% died during the following four days and all lost weight i...

LmCYP4G102: An oenocyte-specific cytochrome P450 gene required for cuticular waterproofing in the migratory locust, Locusta migratoria

Cytochrome P450 superfamily proteins play important roles in detoxification of xenobiotics and during physiological and developmental processes. To contribute to our understanding of this large gene family in insects, we have investigated the function of the cytochrome P450 gene LmCYP4G102 in the migratory locust Locusta migratoria. Suppression of LmCYP4G102 expression by RNA interference (RNAi...

Insect antifeedants, pterocarpans and pterocarpol, in heartwood of Pterocarpus macrocarpus Kruz.

The insect antifeedant activities of pterocarpans and a sesquiterpene alcohol from the dichloromethane extract of Pterocarpus macrocarpus Kruz. (Leguminosae) were evaluated against the common cutworm, Spodoptera litura F. (Noctuidae), and the subterranean termite, Reticulitermes speratus (Kolbe)(Rhinotermitidae). Three pterocarpans, (-)-homopterocarpin (1), (-)-pterocarpin (2), and (-)-hydroxyh...
