What's eating my hoya diptera?

Hoya diptera is a lesser-known collector hoya grown as a tropical houseplant. It shares the standard indoor hoya pest risks: mealybugs are the primary threat, spider mites emerge in dry air, and fungus gnats can damage roots in waterlogged mix. Routine inspection at each watering is the best preventive strategy.

Fluffy white wax at stem nodes and leaf undersides; honeydew deposits attract sooty mold and slow growth Remove with alcohol swabs; apply neem oil spray to the whole plant weekly for 4 weeks; isolate from other plants

Pale stippling on leaf surfaces and webbing on undersides; damage worst in low-humidity winter conditions Shower the plant to dislodge mites; apply insecticidal soap spray; increase humidity with a pebble tray or humidifier

Larvae damage fine feeder roots in overly moist potting mix; stunted growth and yellowing in young plants Allow the potting medium surface to dry between waterings; apply Bacillus thuringiensis var. israelensis drench; use yellow sticky traps
