The aim of this project is to establish a National Reference Laboratory for Dermestidae, with particular reference to the genus Trogoderma. The laboratory will provide molecular and morphological diagnostic services and training. It will also provide a resource for other biosecurity projects, potentially providing methods specific to surveillance and contingency plans, in the event of incursion of pest Trogoderma.

What is the biosecurity problem?

Khapra beetle Trogoderma granarium has been identified by the grains industry as one of the top five biosecurity threats to the industry in Plant Health Australia’s threat risk assessment process. It is recognised as the most serious stored product pest in international trade, and is the subject of strict quarantine measures in many countries.

By definition, Khapra beetles are not present in Australia. It is therefore necessary to obtain validated specimens from a biogeographically diverse range of countries where Khapra beetles can be found. The specimens are then used to develop tests that reliably differentiate Khapra beetle from other related Dermestids known to occur in Australia. 

Diagnostically the Khapra beetle can only be reliably identified by a limited number of highly skilled taxonomists trained in the morphological methods needed to identify these species. Due to their similarity, Warehouse beetle could mask the early detection of the Khapra beetle.

A Diagnostic Reference Laboratory with expertise in morphological and molecular diagnostics will have the capacity to rapidly diagnose suspected specimens of Trogoderma species detected in Quarantine and Biosecurity surveillance.

The main outputs of this project are to:

• establish a National Reference laboratory for Trogoderma diagnostics
• serve as a training vehicle for students and diagnostic specialists throughout Australia for a key biosecurity threat to Australia
• make key diagnostic methods available through the Plant Biosecurity Toolbox, and
• act as a platform for developing surveillance and contingency planning programs.

Who will be the end-users of this research?

State and Commonwealth quarantine organisations, grain handling authorities and private service providers of biosecurity services to the grains and food industries, both nationally and internationally.
