Pest identification
What's eating my yellow passion fruit?
Fruit flies
Signs: Larvae tunnel into ripe fruit, causing internal rot, off-flavors, and premature fruit drop.
Control: Use pheromone or protein bait traps; bag fruit; collect and destroy fallen fruit promptly.
Aphids
Signs: Colonize tender shoots; most critically, they vector passion fruit woodiness virus which disfigures fruit and cripples yield.
Control: Apply insecticidal soap or neem oil; remove and destroy virus-showing vines; use certified virus-free planting stock.
Spider mites
Signs: Fine pale stippling and webbing on leaf undersides, worsening in hot dry periods.
Control: Increase humidity; spray with neem oil or miticide; introduce predatory mites.
Caterpillars (Agraulis vanillae and others)
Signs: Leaf edges chewed or completely stripped on young vines, slowing establishment.
Control: Hand-pick small infestations; apply Bt (Bacillus thuringiensis) spray for larger outbreaks.
