Comparaison des activités insecticides des monoterpènes sur deux espèces d'insectes ravageurs des cultures: Ceratitis capitata et Rhopalosiphum padi

Abstract

Summary: The fumigant toxic effect of some monoterpenoids: α-pinene, linaloi, carvacrol, eugenol, p-cymène, cinnamaldehyde, anethole, terpineol and cuminalde-hyde, was tested upon Rhopalosiphum padi and Ceratitis capitata. The sensitivity of both species to these compounds appears t be variable. The aldehyde and methoxyled monoterpenoids (cinnamaldehyde, cuminaldehyde and anethole) revealed to be more active than hydrogenated ones (α-pinene and p-cymene). The phenolic monoterpenoids present a great activity especially upon C. capitata. © 1997, Taylor & Francis Group, LLC.
