Insect pests represent one of the main factors influencing the steady reduction in Thai cotton production over the last three decades. Misuse of insecticides has brought about profound changes in the composition of the entomo-fauna. Nowadays, farmers' ability to control pests through ecologically and economically sustainable practices is a prerequisite to enhance cotton production in Thailand. A systems approach, consisting of on-farm experiments and surveys, was aimed at investigating the opportunities and obstacles for the integration of IPM techniques into current farmers' pest management practices. Correspondence analysis provides a holistic description of the relationships among components of cotton pathosystem : pest population dynamics, cropping practices and cotton yield losses. The results show that high yields are associated with early sowing and intensive use of insecticides, and thus tend to justify farmers' practices. A comparison of data sets from experiments and surveys helps to analyse the process that led farmers onto an insecticide treadmill. Insecticide use against early season sucking insects enhances the need for further control against bollworms. IPM innovation targeted to this specific multiple pest complex are proposed.
