The banded palomilla, also known as mummy moll moth, Indian flour moth and dried fruit moth is a species of dithrisium lepidoptera of the Pyralidae family originating in Europe and which is now spread throughout the world.
The larvae are introduced inside the grain where they practice galleries. The greatest damages occur in flours, which are contaminated by the simple presence of dejections, exuviums, and silk remains causing the commercial depreciation of the product.
The large amount of cloth that the caterpillars secrete when they move get to cover the surface of the product and may even obstruct the processing machinery in the warehouse.
It affects stored products both grain and its flours and derivatives, dried fruit, etc.
