Annie-Ève Gagnon, PhD

Research scientist

Dr. Gagnon's work helps to predict the impacts of abiotic stress on the development of crop pests, the damage they can cause, and the effectiveness of biological control under extreme climatic conditions. This research will optimize biological control programs in the horticultural sector to reduce the use of pesticides.

Current research and/or projects

Biological control:  effect of climatic extremes on the effectiveness of biological control agents.

Climate change: potential distribution of crop pests, risk of establishment for new exotic species, host plant-pest synchronism.

Insect population genetics and dynamics: trophic interactions, migratory patterns and virulence profile.

Research and/or project statements

  • Optimization of IPM program against the second generation of the carrot weevil

  • Conceptualization and validation of sub-optimal temperature effects on trophic interactions in horticultural crops

  • Identification of reliable bio-indicators to measure crop resilience and to characterize the impact of management practices on soil biodiversity and eco-services

Professional activities / interests

  • Member of Société d’Entomologie du Québec

  • Member of Entomological Society of America
