How to improve plant protection against pest insects?

During the Plants Week, VEGEPOLYS and holders of the French National Research Agency project PHEROTOX invite you to the PHEROTOX conference to provide new perspectives in the field of plant protection.

anr vignetteThe aim of the symposium is to bring scientists together who are working on different aspects of plant protection against insects. We intend to share the actual knowledge on effects of sublethal insecticide doses, and insect sensory systems as targets for alternative pest management strategies with a large scientific and non-scientific public involved in plant production, and protection of the environment.

Plant protection against insect pests, new challenges

Effects of low pesticide residues in the environment lead not only to resistance in pest insects, but can also have unexpected positive effects on life traits, leading ultimately to improved reproduction. On the other hand, communication in "beneficial" insects, such as pollinators can be disturbed. Therefore a reduction in the use of insecticides is an important goal in Europe and the development of alternative pest management strategies becomes a priority. Among the potential targets for new strategies, one of the most important is insect sensory systems, which are of major importance for intra- and interspecific communication.

ANR (French National Research Agency) project PHEROTOX: Pheromone perception in an insecticide-contaminated environment : info-disruption or adaptation?

This symposium is organized in the context of a nationally financed research project on the effects of sublethal doses of a neonicotinoid insecticide on the behaviour and olfactory system of noctuid moths including two partners: The Neuroethology-RCIM group (INRA/Angers University) and the Sensory Ecology Department of the Paris Institute for Ecology and Environmental Sciences (INRA/UPMC).

The first results of our project show dose-dependent effects of sublethal doses of the neonicotinoid insecticide clothianidin on noctuid moths.
