Population dynamics between the mermithid Strelkovimermis spiculatus (Nematoda: Mermithidae) and the floodwater mosquito Ochlerotatus albifasciatus (Diptera: Culicidae) over time

► We conducted a study of population dynamics of Strelkovimermis spiculatus on Ochlerotatus albifasciatus. ► Parasitism by S. spiculatus occurred throughout O. albifasciatus populations developing during all seasons. ► Differing patterns in the infection by the nematode depended on the larval mosquito habitat. ► Flooded area correlated with S. spiculatus infection. ► Mosquito regulation by this parasite involved parasitism levels and infections occurring over time.
