Phyllotreta nigripens (Coleoptera: Chrysomelidae), a new host of Nosema phyllotretae (Microsporida) in Turkey

In the present study we describe a Nosema infection in a Phyllotreta nigripens population. The parasite was identified as Nosema phyllotretae. The spores are oval, 3.97±0.47 μm (2.85–4.75) in length and 2.19±0.36 μm (1.90–2.85) in width. The polar filament has commonly 14 coils. The spore wall is 138–200 nm thick and made up of a clear endospore (88–140 nm) and a uniform exospore (40–70 nm). The polar filament measures 100–125 nm in diameter in the mature spirals. The polaroplast is thin lamellar. This study presents P. nigripens as a new host for N. phyllotretae and a second infection locality in Turkey.
