Abstract Alveolar echinococcosis (AE) is caused by the larval stage of Echinococcus multilocularis . Chemotherapy for AE involves albendazole (ABZ), which has shown insufficient efficacy. More effective chemotherapy needed. Previously, we have demonstrated that atovaquone (ATV), an antimalarial, inhibits mitochondrial complex III E and restricts development cysts in vivo experiments. Therefore,...

Chrysomelinae is one of the largest subfamilies in Chrysomelidae, yet much basic information remains unknown for Neotropical species. The present study aims to compile the first regional list of Chrysomelinae for the State of Rio de Janeiro, Brazil, and assemble natural history traits obtained from our fieldwork from 2005 to 2010 in Serra dos Órgãos National Park, a mountainous area of Atlantic...

For sessile marine invertebrates, processes contributing to larval release, dispersal, and settlement in favourable habitats are central to patterns of distribution and community structure. We quantified larval release patterns, phototactic behaviour, and settlement in response to environmental cues for the coral reef sponge Luffariella variabilis. Individual sponges released up to 830 larvae d...

چکیده بر اساس مطالعات انجام شده در فصول زراعی 1386 و 1387، بعضی از جنبه های زیستی کرم ساقه خوار برنج (chilo suppressalis walker) شامل تعداد سنین لاروی و طول دوره ی رشد و نمو مراحل مختلف زیستی در دو نسل در منطقه ی مازندران بررسی شد. نتایج پژوهش حاضر نشان داد که تعداد سنین لاروی کرم ساقه خوار برنج در نسل های اول و دوم متفاوت می باشد، به طوری که این حشره در نسل اول دارای 6 و در نسل دوم دارای 5 سن ...

Nine species of nematodes, unidentified larval nematodes, three species of trematodes, two species of acanthocephalans and a single species of chewing louse were collected from 1993 to 1995 from 25 introduced whooping cranes (Grus americana) in Florida (USA). In spite of a quarantine procedure involving anthelmintic therapy, three helminth parasites may have been introduced from captive populat...

Cystic echinococcosis is parasitic disease due to the larval stage of the metacestode Echinococcus granulosus in the liver (80%), lungs, kidneys, spleen, myocardium etc. Humans are accidental intermediate hosts. Diagnosis is based on laboratory and imaging studies. Treatment is multimodal, surgical and medical. Risks for dangerous complications and relapses are quite common. Adequate follow-up ...

searching efficiency (a') (attack rate) and handling time are two major components of natural enemies’ functional response and are usually used to evaluate their effectiveness. the age-specific searching efficiency of aphidoletes aphidimyza (rondani) was studied during its larval stage. the experiment was conducted in terms of age-specific functional response to the varying density (5, 1...
