Razak, T.A., & Jayaraj, S. 2002 Incidence of spiralling whitefly and leaf mealybug on coconut.. Insect Environment 8(1) 38-39.

Notes: Heavy infestations of spiralling whitefly (Aleurodicus dispersus) and leaf mealybug (Dysmicoccus carens) were observed on coconuts during March-May 2000, at Dindigul, Tamil Nadu, India. These pests remained on the undersurface of the leaflets, desapping the plant heavily and causing severe yellowing. D. carens excreted honeydew on which the sooty mould (Capnodium sp.) developed, resulting in the reduction of the effective photosynthetic area of the leaflets.
