Crepidodera aurata

A new microsporidian pathogen isolated from Crepidodera aurata was identified based on morphological and ultrastructural characteristics, coupled with a molecular phylogenetic analysis. The spores of the microsporidian pathogen were slightly curved in shape, and measured 2.44–3.55 µm in length and 1.25–1.55 µm in width (n = 50). Its ultrastructure is characteristic of monokaryotic groups. All lifecycle stages of the pathogen, including meronts, sporonts, sporoblasts, and mature spores, are monokaryotic. The spore has 6–8 windings of the polar filament.

Microsporidia are mostly very small, intracellular, spore-forming pathogens classified as Protista and reported in every major group of animals. Insects are one of the most widely distributed hosts for microsporidia. Many entomopathogenic microsporidia cause chronic infections in insects and their effects appear as reduced fertility and pupal weight, reduced fecundity and shortened longevity. Crepidopdera aurata (Coleoptera; Chrysomelidae) is one of the most destructive pests in poplar nurseries.
