An international consortium on genomics-assisted insect pheromone identification

 

Funding period: 2020-2024
Lead: Daniel Doucet
Total GRDI funding: $176,000

The detection of Forest Invasive Alien Species (FIAS) insects is an essential aspect of their integrated management. One of the most commonly used strategy is in the deployment of traps baited with volatile compound blends attractive to adult insects. This project uses a genomics-based strategy to link insect pest sensory genes to their specific ligands, in order to accelerate the discovery and deployment of new attractants or blends. This project's objectives are: 1) the annotation of sensory gene families from FIAS insect species; 2) the establishment of a multi-user, applied sensory genomics platform; 3) the development of novel molecular methods for the discovery of behaviorally-active compounds and; 4) the facilitation of international cooperation in insect sensory genomics and chemical ecology. Expected benefits include the faster development of effective attractants against FIAS and therefore a more rapid reaction time in terms of forest pest management.
