This investment is investigating the geographical variation of the sex pheromone in fall armyworm populations in Australia. This information will assist in optimising pheromone blends in lures for monitoring and mass trapping and application in mating disruption.

The analysis of pheromone blends of Australian populations of fall armyworm will inform the development of regionally effective products that the horticulture industry can adopt to improve surveillance and develop an integrated pest management system involving biological control and cultural practices aimed at reducing the use of chemical pesticides.
