Catalogue
of the Lepidoptera of Belgium


Phthorimaea operculella (Zeller, 1873)

A pest species, not often recorded in Belgium.

The rosy white larva develops usually in potato tubers, but when it emerges on leaves, it forms a gallery and penetrates the fruits, stems and leaves of Lycium europaeum, Lycopersicon esculentum, Nicotinia tabacum and different species of Solanum. Larval development only above temperatures higher as 10°C. Hibernation as egg and later it pupates in a very narrow whitish cocoon.

Usually around six generations a year in Mediterranean regions, but it appear usually from April till October with the generations overlapping each other.
