Product Details
Thripor (Orius insidiosus) — Predatory Bug for Thrips Control
Thripor contains Orius insidiosus, a proven predatory bug for controlling thrips larvae and adults. These predators actively hunt across plant surfaces, including leaves and flowers, piercing and consuming prey. Adults included in the product fly and disperse from release points to locate thrips throughout plants. Thripor is chemical-free, IPM-compatible, and safe for use in greenhouses, nurseries, interiorscapes, outdoor landscapes, indoor plants including houseplants and more.
Immediate release: Adults and nymphs begin feeding upon application
High mobility: Adults fly and move quickly to find prey across plants
Effective control: Targets thrips larvae and adults for reliable population reduction
Use For
Thripor targets thrips species, including:Western flower thrips (Frankliniella occidentalis)
Onion thrips (Thrips tabaci)
Echinothrips americanus
Other common thrips species (larvae and adults)
When to Use Thripor
Use wherever thrips larvae or adults are present. Effective across all growing environments.
Recommended for:
Active thrips colonies or hotspots
Environments where clean, residue-free control is preferred
Flowers and dense foliage where sprays struggle to reach
How It Works
Mode of Action: Nymphs and adults pierce thrips larvae and adults with their mouthparts and consume the contents
Behavior: Predators hunt actively on leaves and flowers; adults fly and disperse to new feeding sites
Visual Effect: Empty thrips skins (exuviae) appear on leaves and petals as control builds
Feeding Rates
Adults consume ~10–20 thrips per day under favorable conditions
Nymphs focus on larval stages; adults handle both larvae and adults
Intake varies with prey density and plant structure
Lifecycle of Orius insidiosus
Egg Stage
Eggs are inserted into plant tissues without causing damage because Orius uses a fine, non-destructive ovipositor that places eggs just beneath the surface. This process does not disrupt plant growth or create wounds that lead to disease; only a small white cap is visible where the egg is laid.
Nymph Stage
Yellow-orange to brown, wingless, highly mobile on leaves and blooms
Primary focus on larval thrips
Adult Stage
1.5–2.5 mm, black with gray-white markings; fast hunters that fly for dispersal
Development time: Egg to adult in ~3 weeks at 77°F
Release Rates & Application
Pressure Level Definition Rate per 10 sq ft Repeat Interval Preventative Risk present; no visible thrips 0.5–1 Every 7–14 days Low Pressure Thrips in localized areas 1–3 Weekly Medium Pressure Thrips visible across multiple zones 3–6 Weekly High Pressure Widespread thrips; feeding damage visible 6–9 Weekly or twice weekly in hotspots
Application Notes:
Shake gently before use
Apply directly onto leaves and flowers or place in Dibox release boxes near hotspots
Focus on blooms and dense foliage where thrips concentrate
Evening releases support settling and early feeding
Apply in clusters of 50–100 predators per drop point to promote mating and establishment
Best Working Conditions
Temperature: Effective from 68–86°F; cooler conditions slow development
Humidity: Moderate to high RH supports activity and reproduction

What to Expect
Thripor predators begin hunting immediately after release. Adults fly and disperse, extending coverage beyond initial drop points. Control builds as predators spread through affected areas. Reapply per scouting to maintain control.
Recommended IPM Pairings
Thripex / Thripex-V (Neoseiulus cucumeris) to control early-stage larvae hidden in flowers and foliage, while Thripor hunts down adults and larger nymphs. Together, they break the thrips life cycle.
Entonem (Steinernema feltiae): For soil pupae control; complements Thripor’s foliar activity by targeting thrips life stages in the soil.
Isarid® Mycoinsecticide: Adds a fungal mode of action for mealybugs and soft scales in high-pressure zones; fully compatible with beneficials.
Dune™: Improves plant resilience against sucking pests, reducing overall pest pressure and supporting IPM longevity.
Essential Oil Knockdown (e.g., neem-based): For pre-release reduction of heavy mealybug populations; apply beneficials after residues dry.
FAQs
Does Thripor kill adult thrips or only larvae?
Thripor targets both larvae and adults.
Does Thripor contain adults, and do they fly?
Yes—Thripor includes adults and nymphs. Adults fly and disperse quickly.
How soon will I see results?
Feeding starts immediately. Control builds quickly as predators move through affected areas.
Is Thripor suitable for indoor plants and interiorscapes?
Yes—Thripor is chemical-free and fits clean environments. Adults fly but remain where prey is present.Questions about Thripor?
