What's eating my curry leaf plant?
Curry Leaf Psyllid (Diaphorina communis)
Signs: Leaves curl inward and distort; tiny jumping insects and waxy 'lerp' deposits on young growth; severe infestations stunt plants.
Control: Spray thoroughly with neem oil or insecticidal soap, targeting new growth. Remove and destroy heavily infested shoots. Repeat every 7–10 days.
Mealybugs
Signs: White waxy clusters in leaf axils and along stems; weakened growth and sticky honeydew leading to sooty mould.
Control: Wipe off with 70% isopropyl alcohol on cotton swabs; apply neem oil spray for heavier infestations. Isolate from other plants.
Scale insects
Signs: Brown or tan armoured bumps on stems and leaf midribs; yellowing and dieback above feeding sites.
Control: Scrape off manually; treat with horticultural oil or neem oil spray. Systemic insecticides (imidacloprid) reserved for severe cases.
Citrus swallowtail caterpillars (Papilio demoleus)
Signs: Whole leaves consumed rapidly; characteristic green-and-white bird-dropping-mimicking larvae on outdoor plants.
Control: Hand-pick larvae; these are protected pollinators in some regions — relocate rather than destroy if possible. Use Bt (Bacillus thuringiensis) spray for heavy infestations.

Curry Leaf Plant is heavily targeted by citrus mealybugs and psyllids — especially the Curry Leaf Psyllid (Diaphorina communis) which causes leaf curl and stunting. Aphids and scale insects also attack. Outdoors in warmer regions, caterpillars (particularly swallowtail butterfly larvae) and whitefly are common. Regular inspection is essential during the growing season.
