What's eating my streptocarpus 'chorus line'?

Streptocarpus 'Chorus Line' is grown indoors and shares the pest vulnerabilities of the wider Cape primrose genus. Mealybugs are the most common problem, followed by aphids on flower stems and vine weevil grubs at the roots. Thrips occasionally scar the hairy leaf surfaces. Regular inspection prevents escalation.

Cottony white residue tucked into leaf folds and stem bases; sticky foliage with sooty mould Targeted isopropyl alcohol application; neem oil foliar spray; isolate plant and repeat every 7–10 days

Sticky honeydew on emerging growth; distorted buds and clustering insects on flower scapes Insecticidal soap or a strong water rinse; weekly monitoring during flowering

Unexplained wilting; grubs consuming roots and crown tissue when plant is unpotted Nematode drench in autumn; replace infested compost; do not reuse soil from affected pots

Silvery stippling and streaking on textured leaf surfaces; distorted flowers Blue sticky traps at canopy level; remove worst-affected leaves; spinosad spray if persistent
