Preventive biological control, natural-enemy selection, compatibility, environmental fit, sticky-card monitoring, scouting, and recordkeeping.
Protected Cultivation
Biological Control Program Design
Biological control works best as a planned IPM component: correctly identify the pest, match a beneficial organism to the pest and life stage, introduce it early enough, and verify establishment through scouting.
Key concepts
- Different beneficial organisms target different pests and life stages
- Environmental conditions affect beneficial performance
- Preventive or early releases can be more effective than waiting for heavy infestations
- Broad-spectrum pesticide residues can disrupt beneficial populations
What to measure or observe
- Confirm pest identity before selecting a biological control
- Track beneficial releases by date and location
- Scout for both pest and beneficial populations
- Review pesticide compatibility before combining tactics
Common mistakes
- Releasing a beneficial without confirming the target pest
- Expecting immediate knockdown from a population-based biological program
- Ignoring temperature and humidity requirements
- Using incompatible pesticide residues without checking effects on beneficials
Visuals this lesson still needs
- Pest-to-beneficial matching matrix
- Preventive-release timeline
- Scouting feedback loop
- Compatibility decision diagram
