Life history and host specificity of Mediorhynchus centurorum Nickol 1969 (Acanthocephala: Gigantorhynchidae).
Examination of 1905 arthropods from a swamp and surrounding pasture in sothern Louisiana revealed larval specimens of Mediorhynchus centurorum in 8 of 228 woodroaches, Parcoblatta pensylvanica, but in no other species. The life cycle was confirmed by feeding eggs of M. centurorum to laboratory-reared woodroaches. Cystacanths later recovered from the woodroaches developed into mature worms when ...
متن کاملA Review of Host Specificity in Tanaorhamphus longirostris (Acanthocephala: Neoechinorhynchidae)
Of 13 species of fish recorded as hosts for the acanthocephalan, Tanaorhamphus longirostris (Van Cleave 1913), only two regularly contain mature worms. These are the gizzard shad (Dorosoma cepedianum (Lesueur)) and the threadfin shad (D. petenense (Giinther)). To date, only one species of intermediate host, the calanoid copepod, Diaptomus pallidus Herrick, has been reported. In Caesar Creek Lak...
متن کاملAcanthocephala of Louisiana Picidae with description of a new species of Mediorhynchus.
One hundred eighty-three woodpeckers of eight species collected in Louisiana were examined for Acanthocephala. Only the red-bellied woodpecker, Centurus carolinus, was infected. One of 53 was parasitized by an irrunature specimen of Mediorhynchus grandis; three by Centrorhynchus spinosus; 12 by Mediorhynchus centurorum sp. n. The new species of Mediorhynchus is distinguished by a trunk which is...

کفشدوزک خربزه، Epilachna chrysomelina (F.)، یکی از آفات کلیدی گیاهان جالیزی در آسیا و شمال آفریقا میباشد. طول دورهی رشد، تولید مثل و پارامترهای جدول زندگی این کفشدوزک روی گیاهان هندوانه، خیار چنبر، خیار و خربزه در شرایط آزمایشگاهی (دمای 30 درجهی سیلسیوس، رطوبت نسبی 60 درصد و طول دورهی روشنایی به تاریکی 14 به 10 ساعت) مطالعه شد. میانگین طول دورهی زندگی از تخم تا مرحلهی بلوغ ماده روی هندوانه، خیا...
متن کاملHost life history responses to parasitism.
Parasites and their infections can adversely effect a host's growth, reproduction and survival. These effects are often not immediate, but increase with time since infection. A general prediction from evolutionary biology is that hosts suffering from this type of infection should preferentially allocate resources towards reproduction, even if this is at the expense of their growth and survival....
