What's eating my encephalartos villosus?
Armored scale insects (Pseudaulacaspis spp., Aonidiella aurantii, Chrysomphalus aonidum)
Signs: Hard shell-like insects fixed to leaflets suck sap, causing yellowing, browning, and dieback of fronds in severe infestations
Control: Apply horticultural white oil (soluble oil) frequently and thoroughly; repeat every 2–3 weeks; systemic insecticide for persistent infestations
Mealybugs (Pseudococcus longispinus)
Signs: White cottony clusters in leaf sheaths and at frond bases; honeydew promotes sooty mold and attracts ants that protect the colony
Control: Spot-treat with isopropyl alcohol; spray neem oil or insecticidal soap thoroughly; check crown and cone bases carefully
Moth caterpillars (spotted and inflamed tigerlet species)
Signs: Larvae chew leaflet margins and leaf tissue; usually minor and cosmetic unless populations are very high
Control: Handpick caterpillars; spray Bacillus thuringiensis (Bt) for larger infestations; damage is rarely plant-threatening

Encephalartos Villosus pests — FAQ
What is eating my encephalartos villosus?
Encephalartos villosus (forest cycad) is susceptible to several armored scale species documented in South African cultivation research, plus mealybugs and occasional moth caterpillars. Scale insects are the primary serious threat, extracting sap from leaves and causing significant dieback if populations build up unchecked.
