Dr. Simon Lachance

Veterinary Entomology and Pest Management in Organic Systems

Degrees:

Ph.D. Entomology (Biological Control) – University of Guelph (2000)
M.Sc. Biology – Laval University (1996)
B.Sc. Agronomy – Laval University (1993)

Research Interests:

My research program focuses on integrated pest management (IPM) for the control of pest organisms (external and internal parasites) in livestock production. I develop and evaluate low-risk methods and products that could be of use for both conventional and organic production systems, with a special interest on plant-based repellents.

Current Projects:

  • Bioactive products from plants and control of internal and external parasites in large ruminants
  • Control of houseflies in poultry production
  • Best management practices for control of nuisance flies dispersing through the Ontario grape and wine value-added industry chain
  • Risk assessment of neoclassical biological control of Lygus bugs with Peristenus digoneutis in Canada
  • Optimizing green manure and fertility management for organic cereal production
