Record of pests infesting arecanut, Areca catechu Linneaus and their seasonal incidence.

Abstract

Observations on the seasonal dynamics of arecanut pests were recorded at fortnightly intervals from March 1998 to February 1999 at 10 villages of Ranagari district in the Konkan region of Maharashtra, India. Five major insect species, i.e. butterfly (Elymnias caudata), grasshopper (Morismus carinatus), scale (Aonidiella orientalis), aphid (Cerataphis lataniae) and mealy bug (Icerya aegyptiaca), 5 minor insect species, i.e. red ant (Oecophylla smaragdina), termite (Odontotermes obesus), shot hole borer (Xyleborus perforans), stem weevil (Diocalandra stigmaticollis [D. frumenti]) and thrips (Rhipiphorothrips cruentatus), and 2 non-insect species, i.e. striped squirrel (Funambulus sp.) and frugivorous bat (Pteropus sp), were found infesting different parts of arecanut plants. The populations of the butterfly and grasshopper were highest in September, whereas those of scale, aphid and mealy bug were highest in January, May and February, respectively. The populations of the striped squirrel and frugivorous bat were highest in September and March, respectively.
