Abstract

Early detection of invasive species of wood boring Coleoptera in imported plants and plant products is of considerable importance due to the potential environmental impact and high cost of eradication if the species becomes established. Detection is made difficult as in the majority of cases, there is little or no evidence of the presence of larvae inside the imported material. Acoustic methods can be employed to detect movement and feeding activity and also identify the species if it has distinctive feeding characteristics. This paper reports on progress into the design and preliminary testing of practical devices for use by plant health inspectors.
