A Nosema-type microsporidian in Ectomyelois ceratoniae (Lepidoptera: Pyralidae)
1991
Lange, C.E.
Light and electron microscopy observations were conducted on a microsporidium (Protozoa: Microspora) detected in the Malpighian tubules of Ectomyelois ceratoniae from Tupungato, Mendoza Province, Argentina. The characteristics showed by the pathogen (monomorphic, diplokaryotic, apansporoblastic) allowed its placement in the genus Nosema. Unusually elongated sporoblasts appeared to be a particular attribute of the pathogen. Experimentally induced infections will be necessary to find out if other differential characters are present. The finding represents only the second report of microsporidia in argentine Lepidoptera.
