What's eating my pitcher plant 'ventrata'?

Nepenthes x ventrata is a robust hybrid rarely troubled by pests. Mealybugs occasionally infest stem nodes; scale insects appear on stems and pitcher lips in poor-ventilation conditions; fungus gnats breed in consistently wet sphagnum moss media. Aphids may visit new growth. Treat gently — avoid systemic insecticides in the pitchers, which would disrupt digestion.

White powdery masses at stem nodes and under pitcher lids; honeydew deposits; weakened growth tips Remove with a cotton swab dipped in isopropyl alcohol; spray neem oil on stems and foliage, avoiding pitcher fluid

Hard brown bumps fixed to stems or pitcher surfaces; yellowing and stunted growth Scrape off with a soft brush; treat with horticultural oil spray on affected surfaces; improve airflow around the plant

Larvae in wet sphagnum media; minor root damage; adults hovering around the plant Reduce standing water around the base; apply Bti (Bacillus thuringiensis israelensis) drench; use yellow sticky traps
