Ecological vs physiological host specificity: the case of the microsporidium Nosema pyrausta (Paillot) Weiser, 1961
The microsporidium Nosema pyrausta (Paillot) Weiser, 1961 plays an important role in the mortality of the European corn borer Ostrinia nubilalis (Hübner, 1796), and shows high virulence to the beet webworm Loxostege sticticalis (Linnaeus, 1761). In contrast, the greater wax moth Galleria mellonella...

The microsporidium Nosema pyrausta (Paillot) Weiser, 1961 plays an important role in the mortality of the European corn borer Ostrinia nubilalis (Hübner, 1796), and shows high virulence to the beet webworm Loxostege sticticalis (Linnaeus, 1761). In contrast, the greater wax moth Galleria mellonella (Linnaeus, 1758) and the gypsy moth Lymantria dispar (Linnaeus, 1758) are referred to as resistant hosts, slightly susceptible to this microparasite. The goal of the present study was to test N. pyrausta against a broad range of lepidopteran species with different taxonomy, physiology, and ecology.
