What's eating my 'jalapeño' pepper?
Pepper weevil (Anthonomus eugenii)
Signs: Adults feed on flower buds and young fruit; larvae develop inside pods causing premature fruit drop.
Control: Remove and destroy dropped fruit daily; apply kaolin clay; use spinosad or pyrethrin if populations are high; rotate planting location.
Aphids (Myzus persicae)
Signs: Colonies on new growth; honeydew and sooty mould; virus transmission.
Control: Blast with water; insecticidal soap; reflective mulch; companion-plant with coriander to attract hoverflies.
Thrips (Frankliniella occidentalis)
Signs: Silvery scarring on pepper skin; distorted flowers; reduced fruit set; virus vector.
Control: Blue sticky traps to monitor; spinosad spray; predatory mites (Amblyseius cucumeris) for biocontrol.
Flea beetle (Epitrix spp.)
Signs: Shot-holes in leaves of young plants post-transplant; can stall establishment.
Control: Floating row covers for first few weeks; kaolin clay barrier on foliage.
