The most current information on thrips and whitefly IPM is now at your fingertips at greenhouseipm.org.

GreenhouseIPM.org provides detailed descriptions of pests, biocontrol agents  and detailed instructions on how best to use biocontrols within an IPM program.

Its initial format it focuses on two key pests – whiteflies and thrips – and their control. The site will evolve to encompass all common insect and mite pests, as well as diseases, in greenhouse crops.
