Pepper Thrips
Thrips species attacking peppers and ornamentals, causing scarring and bronzing.
Pepper thrips (including Thrips nigropilosus and related species) attack peppers, ornamentals and some bedding plants. Damage includes silvering, bronzing, scarring and distorted growth, particularly in flowers and young leaves. Biological control relies on predatory mites such as Amblyseius swirskii and Transeius montdorensis, and Orius bugs where flowering is present. Early detection and higher introduction rates are needed where pepper thrips are established.
Biological Controls for Pepper Thrips
The species below are examples of beneficial organisms commonly used against pepper thrips. 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 cucumeris + Orius laevigatus
Environment: glasshouse
Temperature Range: 18.0 – 32.0°C
Rate: Amblyline 50–100 mites/m²; Oriline 0.5–2 bugs/m²
Frequency: Introduce mites preventatively; add Orius once flowers appear
IPM combination for thrips in peppers and chillies; support with sticky traps and careful chemical choice.
Orius majusculus
Environment: all
Temperature Range: 15.0 – 30.0°C
Rate: 0.5–2/m²
Frequency: introduce early; top up as needed
Leaf-active Orius species suited to vegetative thrips pressure. Performs well in cooler crops. Best where leaf-stage feeding dominates.
