Leafhopper
Sap-feeding pest causing hopper burn and stippling.
Leafhoppers (Empoasca spp. and related species) feed using piercing-sucking mouthparts, causing white stippling, hopper burn, leaf cupping and reduced vigour. Adults are very mobile and nymphs run sideways when disturbed. Biological controls include Orius species, Amblyseius swirskii and Beauveria bassiana, supported by good weed control and crop hygiene.
Biological Controls for Leafhopper
The options below are examples of beneficial insects and biological products commonly used against leafhopper. Always refer to supplier guidance and product labels for crop safety and local registration status.
Chrysoperla carnea
Product: Chrysoline
Environment: outdoor
Temperature Range: 16.0 – 28.0°C
Rate: 5–10 larvae per hotspot area
Frequency: Repeat 2–3 weekly as required
Lacewing larvae provide broad control of leafhopper nymphs on many outdoor crops.
Orius laevigatus
Product: Oriline
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.)
