Characteristic Features of Nosema phyllotretae Weiser 1961, a Microsporidian Parasite of Phyllotreta atra (Coleoptera: Chrysomelidae) in Turkey

Mustafa Yaman, Renate Radek, Irfan Aslan, and Ömer Ertürk (2005) Characteristic features of Nosema phyllotretae infecting Phyllotreta atra collected in Gümü hane, Turkey are given in this paper. Fixed and stained spores are oval, 4.08 ± 0.56 (range, 2.90~5.20) µm in length and 2.53 ± 0.33 (range, 1.80~2.90) µm in width (n = 50) with 14 coils of the polar filament. The spore wall is 110 to 175 nm thick and made up of a clear endospore (90 to 125 nm) and a uniform exospore (50 to 64 nm). The anterior region of the polaroplast is thinly lamellar. The ultrastructural features of Nosema phyllotretae differ from those of other chrysomelid parasitic microsporidia.
