Green Leafhopper
Small green leafhoppers causing hopper burn, yellowing and reduced vigour.
Green leafhoppers (Empoasca spp.) are small, active sap-feeding insects that move quickly and jump when disturbed. They cause hopper burn, yellowing, leaf margin necrosis and reduced plant vigour. They can occur on fruit, ornamentals and protected crops. Biological control uses generalist predators such as Orius spp. and predatory mites, supported by weed control and avoidance of excessive nitrogen.
Biological Controls for Green Leafhopper
The species below are examples of beneficial organisms commonly used against green leafhopper. 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.
Orius laevigatus
Environment: glasshouse
Temperature Range: 16.0 – 28.0°C
Rate: Orius 0.5–1 bug/m²; Chrysoline 5–10 larvae/hotspot
Frequency: Re-introduce after 3–4 weeks if needed
Generalist predators feeding on leafhopper nymphs and other soft-bodied pests. (Split from combo card.)
Chrysoperla carnea
Environment: glasshouse
Temperature Range: 16.0 – 28.0°C
Rate: Orius 0.5–1 bug/m²; Chrysoline 5–10 larvae/hotspot
Frequency: Re-introduce after 3–4 weeks if needed
Generalist predators feeding on leafhopper nymphs and other soft-bodied pests. (Split from combo card.)
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 suited to vegetative/leaf-feeding thrips and other small soft-bodied prey. Use as a support predator layer with monitoring.
