Two-Spotted Spider Mite (Tetranychus urticae)
Highly damaging mite causing bronzing, webbing and rapid population growth.
Tetranychus urticae is the most widespread spider mite pest. It thrives in hot, dry conditions and causes leaf bronzing, stippling and extensive webbing. Reproduction is rapid, leading to sudden crop decline. Biological control includes Phytoseiulus persimilis for curative hotspots, and Amblyseius swirskii / andersoni for preventative programmes.
