Red spider mite: Presence of chlorotic spots which coleasce into pale patches indicated the presence of infestation. These critters can damage plants by sucking on the tissues, mainly in the leaves. The mites often cluster on the undersides of the leaves.
Bormia variegate or Baculovirus caterpillar: The larvae consumes the entire green tissues of leaf, leaving only the mid vein and some basal portion of leaf. It is more in May-July and Oct-Dec season.
They occurs in two colour forms, green with dark lines or pale yellowish brown and has a full size of 2.0 to 2.5 inches. The larvae consumes the leaf completely leaving the mid vein and some basal portion of leaf. The larval attack on the plant was in peak during June to October. During 2011. Screening of viral infected larvae was used for isolating baculovirus at Rain Forest Research Institute, Jorhat
Use Manjastra or Guruastra solution to prevent infestation. See my blog for preparation of Manjastra and Guruastra.
