What's eating my alocasia sinuata?

Alocasia sinuata, known for its quilted, glossy leaves, is grown as an indoor collector's plant. Spider mites are the most common attacker in warm, dry rooms. Mealybugs are fond of its corrugated leaf surfaces where they hide deep in the texture. Thrips and scale are also encountered. High humidity is the best preventive.

Dusty pale speckling on the glossy upper leaf surface; webbing beneath in heavy infestations Rinse leaves thoroughly, boost humidity, and spray with diluted neem oil or insecticidal soap weekly until resolved.

White cottony deposits lodged in the leaf quilting and petiole joints; honeydew makes surfaces tacky Dislodge with isopropyl alcohol on a swab; follow with systemic neem oil treatment weekly for a month.

Silver-scarred patches on new growth; distorted leaf margins as the leaf unfurls Isolate the plant, prune heavily affected leaves, and apply spinosad or insecticidal soap every 5–7 days for three rounds.
