What's eating my rose apple?

Rose Apple (Syzygium jambos) is most commonly attacked by fruit flies, which ruin ripening fruit, and psyllids that cause leaf curl. Scale insects and mealybugs infest stems. Fruit bats raid ripe fruit in tropical gardens. The single worst threat is fruit flies, which make fruit inedible if unmanaged.

Maggots tunnel through ripening fruit, causing premature drop and rot Use protein bait traps, harvest promptly, bag developing fruit, remove fallen fruit immediately

Leaf margins curl, pucker, and distort; nymphs feed under curled leaf edges Prune affected shoots, apply neem oil or insecticidal soap, encourage natural predators

Waxy brown or white bumps on stems and leaves; sooty mold follows honeydew Scrub off by hand, apply horticultural oil spray, repeat fortnightly
