Product Description
Aggressive Thrips and Mite Control with Orius insidiosus
ORIUSforce™ delivers live Orius insidiosus, the minute pirate bug, a fast-moving generalist predator that growers lean on first for thrips. Adults attack all mobile stages of thrips, while the nymphs zero in on the young larval stages that are most vulnerable to predation. The same hunt extends to spider mites, aphids, whiteflies, and other small soft-bodied pests, and a healthy Orius kills more thrips than it actually eats. When prey runs thin they feed on pollen, so a release holds its ground between pest flare-ups. Supplemental feeding with NUTRIforce™ keeps adults laying eggs while the population builds.
Timing matters. Release at sundown the day the bottle arrives. Gently rotate it to mix the predators through the carrier, then tap the adults onto foliage at your thrips hot spots. Tuck the open bottle into a heavily infested plant so stragglers leave on their own. Conditions count too: aim for temperatures above 59°F and relative humidity over 60%. Under that window, newly hatched nymphs appear within 10–14 days. Thrips pressure drops off noticeably 4–6 weeks after release. They may bite.
Where the Minute Pirate Bug Fits in Your IPM Program
Don’t lean on Orius insidiosus alone. It earns its keep alongside other biological control agents in a planned IPM program. The crop list is broad: vegetable, fruit, and ornamental crops, hemp and cannabis, and nursery trees and shrubs. It works in greenhouses, indoor facilities, fields, gardens, and orchards. When pest numbers drop, build a banker-plant system near release points. Pollen-rich plantings like ‘Purple Flash’ ornamental peppers and Sweet Alyssum keep adults breeding and on-site. One caution: in short-day conditions the nymphs can slip into diapause, so supplemental lighting keeps the population reproducing.
Key Features
- Broad pest range: Hunts thrips, spider mites, aphids, whiteflies, and other small soft-bodied arthropods.
- All-stage thrips predation: Adults take every mobile thrips stage while nymphs target the vulnerable first and second instars.
- Wide crop fit: Suited to vegetable, fruit, and ornamental crops, hemp and cannabis, and nursery trees and shrubs.
- Flexible use sites: Performs in greenhouses, indoor facilities, fields, gardens, and orchards.
- Pollen feeding: Survives on pollen between pest flare-ups, so a release persists when prey is scarce.
- Supplemental feeding: Pairs with NUTRIforce™ to sustain egg-laying as the colony establishes.
- Banker-plant ready: Sustained on ‘Purple Flash’ ornamental peppers and Sweet Alyssum for long-term thrips suppression.
- Optimal conditions: Most active above 59°F with relative humidity over 60%.
- Carrier and pack options: Live adults in vermiculite or buckwheat carrier in 500, 1,000, or 2,000 counts.
- Diapause advisory: Add supplemental lighting in short-day conditions to keep nymphs out of diapause.
