Source publication
Biocontrol potential of nepidae bug, Nepa cinerea against immature stages of Anopheles stephensi, Anopheles culicifacies, Culex quinquefasciatus and Aedes aegypti was studied under laboratory conditions. It was found that N. cinerea had the highest predation against An. stephensi followed by An. culicifacies, Cmx quinquefasciatus and Ae. aegypti. F...

Problems associated with resistant mosquitoes and the effects on non-target species by chemicals, evoke a reason to find alternative methods to control mosquitoes, like the use of natural predators. In this regard, aquatic coleopterans have been explored less compared to other insect predators. In the present study, an evaluation of the role of the...
Biocontrol potential of dragonfly nymph, Brachythemis contaminata Fabricius against the larvae of Anopheles stephensi, Culex. quinquefasciatus and Aedes aegypti was studied under laboratory conditions. It was found that dragonfly nymph had highest predation efficacy against An. stephensi followed by Cx. quinquefasciatus and Ae. aegypti. Feeding rat...

... La transmisión de la FA es a través de la picadura de mosquito (4,5,6); en la modalidad urbana de la enfermedad está implicado el Aedes aegypti, del cual existen varios modelos para su control, debido a su participación como vector del virus Dengue (7,8,9,10). En la modalidad selvática en América, encontramos a los géneros Haemagogus spp y de éste se ha comprobado que no solo una variedad del mosquito es capaz de ejercer el papel de vector (11,12,13). ...
Yellow fever is a viral disease, typical of some tropical regions in South America and Africa, causing numerous epidemics with high mortality rates. In order to characterize retrospectively the jungle yellow fever outbreak in Venezuela in the year 2003, by determining the number of cases and deaths confirmed in the affected states according to age, sex, occupation and origin and by identifying factors that triggered the outbreak, as well as the study of cases reported in 2004 and 2005, cases officially registered in the State of Zulia were studied for the period in question. Zulia was the state most affected during the period evaluated, with 25 cases (p
The risks of Aedes aegypti and Aedes albopictus nuisance and vector‐borne diseases are rising and the adverse effects of broad‐spectrum insecticide application have promoted species‐specific techniques, such as sterile insect technique (SIT) and other genetic strategies, as contenders in their control operations. When specific vector suppression is proposed, potential effects on predators and wider ecosystem are some of the first stakeholder questions. These are not the only Aedes vectors of human diseases, but are those for which SIT and genetic strategies are of most interest. They vary ecologically and in habitat origin, but both have behaviorally human‐adapted forms with expanding ranges. The aquatic life stages are where predation is strongest due to greater resource predictability and limited escape opportunity. These vectors' anthropic forms usually use ephemeral water bodies and man‐made containers as larval habitats; predators that occur in these are mobile, opportunistic and generalist. No literature indicates that any predator depends on larvae of either species. As adults, foraging theory predicts these mosquitoes are of low profitability to predators. Energy expended hunting and consuming will mostly outweigh their energetic benefit. Moreover, as adult biomass is mobile and largely disaggregated, any predator is likely to be a generalist and opportunist. This work, which summarizes much of the literature currently available on the predators of Ae. aegypti and Ae. albopictus, indicates it is highly unlikely that any predator species depends on them. Species‐specific vector control to reduce nuisance and disease is thus likely to be of negligible or limited impact on nontarget predators. © 2022 The Authors.
