The effects of azadirachtin, a compound from the neem tree. Azadirachata indica A. Juss, were studied during the last-larval instar of Locusta migratoria. A dose-response relationship was established using moult inhibition and mortality as effective paraments. Although injected azadirachtin elicits feeding inhibition, our results prove that moult inhibilitation is due to an interference with the endocrine system rether than to the altered feeding behaviour. Modification and supression of the ecdysteroid titre by azadirachtin is closely correlated with the morphogenetic effects. Inhibition of eclosion processes, however, suggest a wide-spread blockage of factores presumably located in the central nervous system. |
