What's eating my streptocarpus 'polka-dot purple'?

Streptocarpus 'Polka-Dot Purple' is a colorful flowering indoor plant susceptible to vine weevil larvae attacking its roots and mealybugs sheltering in its strap-like leaves. Aphids can colonize flower stems. Good drainage, biological controls, and keeping the foliage dry are the cornerstones of pest prevention for this cultivar.

Scalloped notches around leaf margins from adults; grub feeding on roots causes wilting and plant death Apply biological nematodes (Steinernema kraussei) to moist compost in spring or autumn; inspect and remove larvae at repotting

White waxy deposits in leaf grooves and at the base of flower stems; honeydew and reduced flowering Use a cotton swab with rubbing alcohol to treat colonies; spray with neem oil and repeat every 7 days

Green or black aphids on flower stalks and undersides of young leaves; distorted buds Wipe or spray off with insecticidal soap solution; repeat weekly until absent
