Aims: * Determine the economic impact of thrips on cotton and evaluate new means of control. * Evaluate the range and possible mechanisms of plant resistance to thrips and mites.

After 2 light mite years (1991/92 and 1992193) the cotton industry experienced a season in which outbreaks of mites were widespread.

During the 1970s and 1980s organophosphates (OPs), particularly monocrotophos (first tested 1969-70, registered 1972-73) and profenofos (first tested 1973-74, registered 1978-79), were the mainstay of mite control for

Aims: 1 * Develop a simple mite management package using data collected relating mite infestations to cotton yield loss. * Complete development and validation of functional sampling procedures.
