Amélioration des connaissances sur le ravageur Drosophila suzukii afin d'affiner les méthodes de lutte en verger de cerisiers

Abstract : Drosophila suzukii, a native Diptera of Asia, is an invasive species detected for the first time in Europe in 2008 and now present in most European countries. Its penchant for attacking healthy fruits, its rapid reproductive ability and mobility make this polyphagous insect a pest of great concern. Its official detection in France in 2010 and the economic importance of its damage led Ctifl to begin in 2013 a 3-year CASDAR project: "Drosophila suzukii: knowledge of the pest, risk characterisation and evaluation of control methods for its effective managment" to help producers.This study, forming part of project’s final year, aimed to improve knowledge on Drosophila suzukii’s population movements in cherry orchards and their environment, and assess the sensitivity of cherry’s ripeness stages to the pest. Population monitoring during the three years of project revealed the regular presence of two peaks of catches: in spring and autumn. The catch levels are correlated to certain climatic factors. However, no correlation can still be made between the damage rate and catch totals. Drosophila suzukii is able to lay eggs from the green fruit stage, but the larvae are able to develop only from the ripening stage. These results lead to recommendations for optimizing the positioning of control methods to manage this pest.
