Plain Language Summary
Azadirachtins are natural triterpenoid compounds derived from seed extracts of the Neem tree. They are also the active ingredients of TreeAzin™, a systemic insecticide product recently registered in Canada and the USA for use in integrated management programs targeting the exotic invasive insect pest - Emerald Ash Borer. To facilitate further investigations and potential broader use of this systemic insecticide, we developed a sensitive and selective analytical method for the determination of azadirachtins in foliage and twigs of tree species which are known to be preferred hosts of the Asian Longhorned Beetle (ALB). ALB is another exotic, invasive, wood-boring insect pest that poses a significant threat to both urban and natural deciduous forests of North America. The methodology was successfully applied in a field experiment designed to investigate uptake, translocation and expression of azadirachtins in representative high-value urban trees following stem injection with TreeAzin™. Results of the study document both the quality and applicability of the analytical technique and provide data clearly supporting continued development of this prospective use of TreeAzin™ for control of ALB in urban forest scenarios.
