Epizootiological studies of Amblyospora albifasciati (Microsporidiida: Amblyosporidae) in natural populations of Aedes albifasciatus (Diptera: Culicidae) and Mesocyclops annulatus (Copepoda: Cyclopidae) in a transient floodwater habitat.

Factors affecting horizontal transmission of the microsporidium Amblyospora albifasciati to its intermediate copepod host Mesocyclops annulatus.

Factors that directly impact horizontal transmission of the microsporidium Amblyospora albifasciati to its intermediate copepod host, Mesocyclops annulatus were examined in laboratory bioassays. Results were evaluated in relation to life history strategies that facilitate persistence of the parasite in natural populations of its definitive mosquito host, Ochlerotatus albifasciatus. A moderately...

Biological control of Aedes albopictus (Diptera: Culicidae) larvae in trap tyres by Mesocyclops longisetus (Copepoda: Cyclopidae) in two field trials.

Epizootiology of Amblyospora stimuli (Microsporidiida: Amblyosporidae) infections in field populations of a univoltine mosquito, Aedes stimulans (Diptera: Culicidae), inhabiting a temporary vernal pool.

The epizootiology of the microsporidium Amblyospora stimuli was studied in natural populations of a univoltine mosquito, Aedes stimulans, inhabiting a temporary vernal pool over an 18-year period. The yearly prevalence of benign oenocytic infections in adult females was variable, ranging from 1.0 to 9.6% (mean = 5.1%). The yearly prevalence of transovarially transmitted meiospore infections in ...

Amblyospora khaliulini (Microsporidia: Amblyosporidae): Investigations on its life cycle and ecology in Aedes communis (Diptera: Culicidae) and Acanthocyclops vernalis (Copepoda: Cyclopidae) with redescription of the species.

A multi-year study was conducted to examine the natural ecology of the microsporidium Amblyospora khaliulini and more fully characterize parasite development and histopathology in all stages of its primary mosquito host, Aedes communis and intermediate copepod host, Acanthocyclops vernalis with redescription of the species. A. khaliulini exhibits polymorphic development, produces three morpholo...

Evaluation of Mesocyclops annulatus (Copepoda: Cyclopoidea) as a control agent of Aedes aegypti (Diptera: Culicidae) in Argentina.

We evaluated the potential of Mesocyclops annulatus as a control agent of Aedes aegypti in La Plata city (Argentina). Mosquito larval survivorship due to predation by these copepods was estimated at weekly intervals during the oviposition period of A. aegypti. Mean weekly A. aegypti larval survivorship in cylindrical plastic containers (12 cm height and 11 cm diameter) with copepods was signifi...
