Pest identification
What's eating my aji amarillo pepper?
Aphids (Myzus persicae / Macrosiphum euphorbiae)
Signs: Dense colonies on shoot tips cause curled, sticky leaves; they vector cucumber mosaic virus and pepper mottle virus, causing mosaic and yield loss
Control: Knock off with water jet; insecticidal soap or neem oil spray; introduce parasitic wasps (Aphidius spp.) in greenhouse settings
Two-spotted spider mite (Tetranychus urticae)
Signs: Fine stippling and bronzing of leaves; webbing on undersides in dry, hot weather; severe cases cause leaf drop
Control: Increase humidity; spray with forceful water; apply predatory mites (Phytoseiulus persimilis); neem oil or insecticidal soap
European corn borer (Ostrinia nubilalis)
Signs: Larvae bore into pepper stems and developing fruits leaving entry holes and frass; fruits rot from inside
Control: Apply Bt kurstaki at egg hatch (early instar); remove infested fruits immediately; pheromone traps to time sprays
Flea beetles (Epitrix spp.)
Signs: Tiny round shot-holes across leaves of seedlings and young transplants; severe on stressed plants in sunny beds
Control: Row covers on transplants; diatomaceous earth around bases; spinosad spray when holes appear on young foliage

What is eating my aji amarillo pepper?
Aji Amarillo peppers are most troubled by aphids, which cluster on growing tips and vector pepper viruses. Spider mites thrive in hot, dry spells. Pepper maggot and corn borer larvae tunnel fruits; flea beetles pit young leaves. In garden beds, slugs attack seedlings and deer browse stressed plants. Strong airflow, well-spaced planting, and early monitoring prevent most outbreaks.
