Diversification des stratégies de protection des plantes : Intérêt des monoterpènes

cited By 1International audiencePlant protection requires alternative strategies to control pest insects. Among these strategies, the use of allelochemicals could be focused on two ways involving: - the internal defences of plants by the modification and the orientation of their metabolisms to enhance the production of self-defence components, - the external defences of plants by utilisation of insecticidal soaps containing plant or natural biodegradable products. The ample distribution of terpenoids and their widespread range of activities point them to be examined as new ecological agents for plant protection and insect control. In order to classify their efficiency, the insecticidal activity of monoterpenes, identified as main components of essential oils, was evaluated on insects belonging to Coleoptera, Diptera and Homoptera orders. The structure-activity relationships are discussed
