Verger pommier v1

The PSH Research Unit (Plants and cropping Systems in Horticulture) is located in the heart of the horticultural production zone in South-East France. We develop ecophysiological and agroecological approaches to contribute to the improvement of the quality of fresh fruits and vegetables and to the development of environment friendly cropping systems for the Mediterranean area.

The PSH research unit belongs to the research netwok for Integrated Horticultural Production of the INRA PACA Centre.

Efficacy of 2 botanical aphicides, chicoric and 3,5-dicaffeoylquinic acids, on aphids susceptible and resistant to synthetic insecticides

Abstract : Dicaffeoyltartaric acid (diCT) and 3,5-dicaffeoylquinic acid (3,5-diCQ) extracted from plants exhibit promising aphicidal properties against various aphid species. Tests on laboratory strains and wild populations of Myzus persicae (the green peach aphid) showed variability in sensitivity, with low resistance levels and no cross-resistance with synthetic insecticides. Only a clone of Aphis craccivora, collected from a plant rich in diCT, displayed significant resistance, indicating a high-level resistance mechanism. These active substances remain promising candidates for biological control of M. persicae in agriculture.
