The intestinal tract of herbivorous arthropods provides a microhabitat for a group of protistan and fungal endosymbionts known as trichomycetes. This study reports the discovery of two new trichomycete species in mosquito larvae from freshwater sources and salt marshes in Canada.
The intestinal tract of herbivorous arthropods provides a microhabitat for a group of protistan and fungal endosymbionts known as trichomycetes. Many hosts are the aquatic immature stages of insects. One understudied group is mosquito larvae with only six trichomycete species reported from the mosquito gut, but Smittium culicis Manier and Zancudomyces culisetae Y. Wang, Tretter, Lichtw. & M.M. White are globally distributed and common in these insects. Mosquitoes are mostly found in standing freshwater habitats, but there are species that are found in brackish water pools common in salt marshes. No trichomycetes are reported from salt marsh mosquitoes. A new species, Legerioides culicicola, is described from mosquito larvae from freshwater sources in Nova Scotia (NS) and Prince Edward Island (PEI), Canada, and Smittium gronthidium Strongman & M.M. White is reported for the first time in this host. Smittium culicis is reported from salt marsh mosquitoes from collections in the same provinces in Eastern Canada. Information on the prevalence of mosquito trichomycetes is presented for sites in NS and PEI.
