Progress to date
The GDWQ WG meeting (Geneva, 2004) agreed to add temephos to the rolling revision and decided on a plan of work. No progress had been made on this item by the time of the GDWQ WG meeting (Geneva, 2005). The GDWQ WG meeting (Geneva, 2006) agreed to prepare a background document following discussions with the WHO Vector Ecology and Management Programme. The GDWQ WG meeting (Berlin, 2007; Singapore 2008) agreed on a path forward towards finalizing the background document.
