Thrips parvispinus
Highly invasive thrips species causing scarring, distortion and rapid crop damage.
Thrips parvispinus is an invasive species increasingly found in ornamentals and edible crops. Damage includes silvering, bronzing, scarred leaves, bud distortion and flower abortion. Populations explode rapidly in warm conditions and often resist chemical control. Biological control relies on predatory mites (Amblyseius swirskii, Transeius montdorensis) and predatory bugs such as Orius laevigatus. Early intervention and high-density introductions are essential.
Biological Controls for Thrips parvispinus
The options below are examples of beneficial insects and biological products commonly used against thrips parvispinus. Always refer to supplier guidance and product labels for crop safety and local registration status.
Amblyseius montdorensis + Orius laevigatus
Product: Montyline + Oriline
Environment: glasshouse
Temperature Range: 20.0 – 32.0°C
Rate: Montyline 50–100 mites/m²; Oriline 1–2 bugs/m² in hotspots
Frequency: Re-introduce after 2–3 weeks where pressure is high
Warm-season thrips predator combination; early introductions essential with T. parvispinus.
