Mermithidae) Parasites of Aedes in Western Wyoming
نویسنده
چکیده
Univoltine Aedes mosquito larvae infected lsy Romanonterrnrs sp. were found at 2 localities in Yellowstone National Park, Wyoming. Aedes neuad.ensis, Ae. impiger, Ae. pullntus and Ae. punctor were the predominant host species. Only Ae. neuadensis was common to all sites. Rates of parasitism rangedfrom 55 to 93Vo and differed significantly between localities. Significant annual variation in the rate of parasitism occurred within populations, but neither infection rate nor mean parasite load differed ambng host species. Parasite populations were distributed among_ host spec-ies in proportion to abundance, but distributions of parasites within host species were over-dispersed. Interipecific variation in survival of infected larvae was associated with the degree to which immune responses were manifested in different host species.

Nine species of mosquitoes and several species of non-target aquatic organisms were tested for susceptibility to the mernaithid nematode, Strelkovimermis spiculatus. All species of Anopheles, Aedes, Culex, and Toxorhynchites exposed to S. spiculatus were susceptible. Of the nine mosquito species tested, C. pipiens quinquefasciatus had the greatest tolerance to initial invasion and the highest p...

Distribution and prevalence of Octomyomermis troglodytis (Nematoda: Mermithidae), a parasite of the western tree hole mosquito, Aedes sierrensis.
Octomyomermis troglodytis was found infecting Aedes sierrensis larvae in 14.5% of 165 tree holes sampled between 1982 and 1986. Mermithid infections were detected in tree hole waters that ranged in pH from 6.5 to 9.3 and electrical conductivities between 0.10 and 5.11 mmhos/cm. Third and fourth instar larvae were most frequently infected, and most immatures that succumbed to infections died whi...
