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 species found to be susceptible (with a high proportion of specimens displaying developed infection) included: Evergestis forficalis (Linnaeus, 1758) (Crambidae), Aglais urticae (Linnaeus, 1758) (Nymphalidae), and Dendrolimus sibiricus Chetverikov, 1908 (Lasiocampidae). The species newly found to be highly susceptible (high proportion of infected insects accompanied with high levels of early mortality) were: Spodoptera exigua (Hübner, 1808) (Noctuidae) and Aglais io (Linnaeus, 1758). Large quantities of spores can be produced in vivo using substitute laboratory host A. urticae.
