Forteen species of mosquitoes and several species of non-target aquatic organisms were tested for susceptibility to the neotropical mermithid nematode, Strelkovimermis spiculatus. All species of Aedes, Anopheles, Culex, Isostomyia, and Ochlerotatus and one of the two Psorophora species exposed to S. spiculatus preparasites were parasitized. None of the non-target aquatic organisms exposed to S. spiculatus were infected with the exception of Chironomidae larvae in which nematode penetration was observed although host reaction as form of nematode melanization was determined at 24-48 hours postinfection producing dead of the nematods within the host.
