Rice In Sri Lanka - Pests of Rice
Infestation of grain moth starts in the field and may reach serious levels in the store. The damage is done by larvae which are elongated, dirty white about 8 mm long. The pupa is dark brown. The adult is a small, straw colored moth about 7 mm long; the wings are 15 mm across when open.
Infestation of grain moth could be minimized by sun drying of seeds to minimize moisture content down to 8.0 % and pack in polythene or paper bags.
