Dirección General de Investigación Científica y Técnica, DGICT (España) Diterpenic ryanoids and spiganthines Nonalkaloidal and alkaloidal type Antifeedants Toxicant Spodoptera littoralis Leptinotarsa decemlineata 6 pages, 4 figures, 2 tables.-- PMID: 10552828 [PubMed].-- Printed version published Oct 18, 1999. In this work, we have studied the antifeedant and insecticidal effects of several natural ryanoid diterpenes. These compounds can be classified in two groups according to their chemical structures: ryanodol/isoryanodol-type (nonalkaloidal type) and ryanodine-type (alkaloidal type) ryanoids. The nonalkaloidal ryanoids were isolated from Persea indica (Lauraceae) while the alkaloidal ryanoids (ryanodines and spiganthines) were isolated from Spigelia anthelmia (Loganiaceae). The effects of these compounds on the feeding behavior and performance (with and without piperonyl butoxide pretreatment) of Spodoptera littoralis larvae and Leptinotarsa decemlineata adults indicate that some strongly deterred these insects, L. decemlineata being less sensitive than S. littoralis. Their antifeedant effects did not parallel their toxic action. Additionally, more than 60% of the nonalkaloidal ryanoids were antifeedants and/or toxic in contrast to 30% of active alkaloidal ones, supporting the hypothesis of a ryanodol-specific mode of action in insects. This work has been partialy funded by a grant from DGICYT-Spain (PB97-1226).
