چکیده
Strelkovimermis spiculatus n. sp. (Mermithidae: Nematoda), a parasite of the mosquito Aedes albifasciatus Mac. in Argentina, is described. Diagnostic characters of this species include a ventrally shifted mouth opening and spicules fused at the tips. The mermithid has been reared on Culex pipiens L. larvae in the laboratory.

Mortality in immatures of the floodwater mosquito Ochlerotatus albifasciatus (Diptera: Culicidae) and effects of parasitism by Strelkovimermis spiculatus (Nematoda: Mermithidae) in Buenos Aires Province, Argentina.
Life tables were constructed for six cohorts of immature stages of the floodwater mosquito Ochlerotatus albifasciatus (Macquart) in a park in Buenos Aires, highlighting the mortality attributable to the parasitic nematode, Strelkovimermis spiculatus Poinar & Camino. Two cohorts were selected to compare parasite incidence in all mosquito stages when low and high parasitism occurred. Development ...
متن کاملPathogenicity Tests on Nine Mosquito Species and Several Non-target Organisms with Strelkovimermis spiculatus (Nemata Mermithidae).
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...
متن کاملتولید پشه های بالغ (Dip.: Culicidae) Culex pipiens آلوده به نماتود انگل Strelkovimermis spiculatus (Nematoda: Mermithidae) جهت کنترل به شیوه خود انتشاری
کنترل زیستی پشه‌های ناقل با استفاده از نماتودهای انگل حشرات به دلیل ماهیت ایمن و کم خطر روش، اهمیت خاصی در مدیریت تلفیقی پشه‌ها دارد. نماتود انگل Strelkovimermis spiculatus به‌طور طبیعی مراحل لارویCulex pipiensرا پارازیته می‌کند و در طبیعت به ندرت حشرات کامل Culex آلوده به این نماتود هستند. این پدیده کمیاب به عنوان راهی برای انتقال نماتود تصور می‌شود. پیش فرض مطالعه حاضر این بود که پشه های بالغ...

متن کاملPeroral susceptibility of Aedes albifasciatus and Culex pipiens complex mosquitoes (Diptera: Culicidae) from Argentina to western equine encephalitis virus.
The transmission cycle of western equine encephalitis (WEE) virus in South America is unknown. A WEE virus strain was isolated from Aedes albifasciatus in Argentina during the WEE epizootic of 1982-83. Also, Culex pipiens from Argentina was reported to be able to transmit WEE virus experimentally, but other results indicate that Cx. pipiens from the USA is refractory to this virus. We determine...
