What's eating my few-flowered lysionotus?

Lysionotus pauciflorus is a cool-growing Asian gesneriad kept as a houseplant. Like other Gesneriaceae, it is most commonly attacked by mealybugs, which hide in leaf axils and stem joints. Spider mites can strike in dry indoor air, and fungus gnats breed in overly moist soil. Regular inspection keeps infestations manageable.

Cottony white waxy clusters at stem junctions and leaf axils; leaves turn yellow and growth becomes weak; sticky honeydew may appear Dab each colony with isopropyl alcohol on a cotton swab; remove by hand and treat the whole plant with neem oil spray; repeat every 5-7 days for 3-4 weeks

Fine pale stippling across leaf surfaces; fine webbing between leaves and stems in severe infestations; leaves may turn bronze and drop Raise humidity around the plant; shower foliage to dislodge mites; apply insecticidal soap or neem oil spray to the undersides of leaves; repeat weekly

Tiny dark flies hovering around the soil; larvae in the compost chew fine roots, causing wilting and yellowing in young plants Allow the soil surface to dry between waterings; use yellow sticky traps to catch adults; apply a Bacillus thuringiensis israelensis (Bti) drench to kill larvae in the soil
