Carmine Spider Mite (Tetranychus cinnabarinus)
Red morph spider mite with strong webbing and heat tolerance.
Tetranychus cinnabarinus, often red or deep pink in colour, behaves similarly to urticae but tends to tolerate higher temperatures. Damage includes stippling, bronzing and dense webbing. Biological controls mirror urticae programmes but require earlier intervention and tighter environmental control due to heat-driven reproduction.
Biological Controls for Carmine Spider Mite (Tetranychus cinnabarinus)
The species below are examples of beneficial organisms commonly used against carmine spider mite (tetranychus cinnabarinus).
