IWCSPP 2014 – Chiang Mai, Thailand

International Working Committee of Stored Product Protection

By Tom Mueller

At the end of November 2014, roughly 350 of the best minds in Stored Product Protection, representing 43 different countries, gathered in Chiang Mai in Northern Thailand, a city where thousands of motor scooter taxis called Took Tooks own the road and the Thai food tastes so good one might never want to leave. Topics of discussion included
museum pests, residual insecticides, emerging global issues, fumigation, insect biology, phosphine resistance, monitoring, quarantine, integrated pest management, grain quality,
engineering, and natural products.

In the new Thai conference center, the 11th International Working Conference of Stored
Product Protection kicked off its opening ceremony on November 24th. A ceremony that included a gracious welcome by Dr. Jim Throne, the President of IWCSPP Permanent Committee, and Suwit Chaikiattiyos, the Deputy Director General, Department of Agriculture, Thailand. In all, there were over 250 presentations and posters to
effectively relay four years’ worth of scientific data and a conclusion of how we can best protect the world’s most essential commodities, all within four full days.

The biggest topic of conversation was an update on the worldwide growing concern for phosphine resistance—much of the content revolved around determining whether the insects are truly resistant to the fumigant phosphine or if the pests are simply surviving
due to poor fumigation techniques. While data was provided on both theories, the dialogue proved helpful for future studies and future management of these phosphine resistant stored product pests.

Another subject discussed throughout the conference was the topic of emerging global issues. In recent years there has been a very large push to aid developing countries with cost effective techniques on storing and maintaining high quality grain
to ensure its ability to withstand weather anomalies or the presence of stored product pests. It was proven there have been great strides made by all actively involved in this area of the industry, and we see this by the involvement and backing of The Bill and Melinda Gates Foundation ( and its support for PICS2, the Purdue Improved Crop Storage project (

Dave Mueller, president of Insects Limited, gave a presentation on the FAST Fumigant Scrubbing System. Highlighted was new information about using this liquid fumigant
destruction method under cold conditions for cut flowers, fruits, and vegetables.

The International Working Conference on Stored Product Protection occurs every four years, and it was announced during this years’ closing ceremony that we can expect the same hospitality in Berlin, Germany as this will be the next host site of the 12th IWCSPP
in 2018. For more information about this conference, contact
