Gall Mites
Microscopic eriophyid mites that induce galls, blisters and distorted plant tissue.
Gall mites (Eriophyidae) are microscopic organisms that feed within plant tissue, inducing blistering, leaf deformation, galls, felted patches and reduced growth. They overwinter in buds and become active in spring. Control relies on preventative biological control with predatory mites including Amblyseius andersoni and Amblyseius swirskii, alongside removal of heavily infested growth and promoting strong plant vigour.
Biological Controls for Gall Mites
The species below are examples of beneficial organisms commonly used against gall mites. Recommendations are based on published biological control information and practical IPM experience. Always confirm suitability for your crop, growing system and local conditions before use.
Amblyseius andersoni
Environment: all
Temperature Range: 6.0 – 30.0°C
Rate: 25–50/m²
Frequency: preventative; top up as needed
Preventative predatory mite for eriophyid-type gall mites; establish early and maintain populations through risk periods.
Amblyseius cucumeris
Environment: all
Temperature Range: 10.0 – 30.0°C
Rate: 100–200/m²
Frequency: preventative; top up as needed
Alternative preventative predatory mite option for eriophyid-type gall mites; higher rates recommended under pressure.
