Pest identification

What's eating my jalapeño?

Aphids

Signs: Sticky shoot tips; mottled or puckered leaves from virus infection; honeydew encourages sooty mould

Control: Reflective mulch under plants; insecticidal soap sprays; beneficial insects; remove heavily infested growing tips

Thrips

Signs: Silver-grey streaking and scarring on fruit skin; bronzing of leaves; thrips also spread tomato spotted wilt virus

Control: Blue sticky traps; spinosad spray; remove weeds and plant debris; introduce Amblyseius cucumeris predatory mites

Pepper weevil

Signs: Oviposition punctures on young pods; larvae feeding inside cause misshapen or dropped fruit

Control: Collect and destroy dropped pods; spinosad or pyrethrin; clean up crop residues thoroughly at season end

European corn borer

Signs: Larvae tunnel through pepper walls leaving frass; compromised fruit rots quickly

Control: Btk sprayed at egg-hatch; spinosad; pheromone traps for adult monitoring

Jalapeños share the pepper pest complex: aphids are the top threat, spreading mosaic viruses quickly. Thrips scar developing fruit skin. Pepper weevils and European corn borers bore into pods.
