AI Article Synopsis
- The study reports the first isolation and detailed characterization of Vairimorpha plodiae, a microsporidian pathogen affecting the moth Plodia interpunctella in Turkey.
- It provides specific measurements of the spores, highlighting their oval shape and size, with fresh binucleate spores measuring approximately 4.48 µm in length and 2.21 µm in width.
- Additionally, ultrastructural analysis reveals key features of the spore wall and polaroplast, including distinct layers and arrangements in its composition.
Article Abstract
The present study describes the first isolation and characterization of Vairimorpha plodiae, a microsporidian pathogen of Plodia interpunctella (Lepidoptera: Pyralidae), from Turkey. We present characteristic light and electron microscopical features of the spores. Fresh binucleate spores are oval and measure 4.48 ± 0.23 (4.01-4.84) µm in length and 2.21 ± 0.15 (1.91-2.48) µm in width. Ultrastructural studies showed that the spore wall measures 150 to 200 nm and consists of a clear endospore (125-150 nm) and an electron-dense, uniform, thin exospore (30-50 nm). The polar filament is isofilar and with 10-12 coils. The well-developed polaroplast consists of two parts with thin lamellae anteriorly and thick, irregularly arranged lamellae posteriorly. The identity of our isolate is discussed.
