Its gammaproteobacterial symbiont Candidatus Sodalis pierantonius str. SOPE is able to supply rice weevil with essential vitamins like pantothenic acid, riboflavin, and biotin. [7] During larvae development, bacteria rely on up-regulation of type three secretion system genes and genes for flagellum so they can infect insect stem cells. [8]

Adult rice hispa die 5–6 days after inoculation, and white mycelial growth was observed over the surface of the insect. Infected adults become adhered to leaf surfaces, and after 7–10 days the entire surface of the adults is covered by the fungus. Infected eggs have a white powdery mass around it, surrounded by a yellow halo.
