What's eating my sinningia 'duchess of york'?

Sinningia 'Duchess of York' is grown as an indoor gesneriad and shares the typical indoor pest lineup. Mealybugs are the most common enemy, clustering in the velvety leaf folds. Fungus gnats exploit the humus-rich, consistently moist compost. Thrips occasionally scar the flowers. Vigilant inspection and good air circulation prevent most problems.

Cottony white deposits at leaf axils and stem joints; honeydew and sooty mould Treat colonies with isopropyl alcohol on a cotton swab; follow up with neem oil spray on the whole plant weekly for 3 weeks

Larvae feed on fine roots and organic matter in compost, leading to poor vigour and wilting Let compost surface dry between waterings; use Bti (Bacillus thuringiensis israelensis) drench; place yellow sticky traps

Silver-streaked or distorted petals and buds; tiny dark frass specks on flowers Remove and dispose of damaged flowers; apply spinosad-based spray or insecticidal soap; blue sticky traps help monitor populations
