Khapra beetle (Trogoderma granarium) is one of the five highest-priority threats to the Australian grains industry.

The 10th International Working Conference on Stored Product Protection (IWCSPP) was held in Estoril, Portugal, from 27 June to 2 July 2010.


When: June 2010 - July 2010

Dr Manoj Nayak represented the CRCNPB at the 10th International Working Conference on Stored Product Protection (IWCSPP) - which was held in Estoril, Portugal - where he delivered an oral presentation titled ‘Developing strategies to manage highly phosphine resistant populations of flat grain beetles in large bulk storages’.

Mr Robert Emery attended the International Working Conference on Stored Product Protection where he gave a presentation on the development of pest surveillance data collection software and hardware.


Identifying Khapra beetle

Mr Andras Szito recently visited natural history collections in the United States and Europe to take an inventory of the curated Trogoderma specimens. This research will lay the foundation for future work in the revision of the Trogoderma species.

This project was created as there was a need to develop simple and accurate diagnostics to rapidly distinguish Khapra beetle from its close relatives. The aim of this project was to enhance the capacity to effectively and efficiently identify this species, especially in identifying the highly problematic and particularly difficult larval stages. The development of a broader range of skills and techniques  provided much needed support to existing diagnosticians and taxonomists.

What is the biosecurity problem?

The genus Trogoderma (Grain beetles) contains some of the world's most serious economic pests of wheat and other stored grain products. Even with application of strict quarantine measures, these grain beetles still find their way into new countries. This causes imposition of unfavourable restrictions on exports. It is estimated that the total Australian export revenue at risk by an established Trogoderma granarium (Khapra beetle) infestation is over $1.83 billion annually (mainly attributed to the loss of Pest Freedom status) a scenario that would be detrimental to both the grains industry and the Australian economy.

The outputs of this project were to:

  • train a PhD student in taxonomy and molecular diagnostics
  • conduct a phylogeographic study (a study of geographical distribution of the pest over time) on the three exotic, one introduced and as many as possible of the 52 described native non pest Trogoderma
  • conduct a phylogenetic study (evolutionary relatedness) on Trogoderma species, and closely related beetles in the family Dermestidae
  • develop an accurate Polymerase Chain Reaction (PCR) method for detecting Trogoderma pest species, and
  • investigate the use of protein analysis using mass spectrometry to differentiate selected species.

Who will be the end - users of this research?

Technical Officers and Quarantine inspectors.
