The traditional view of interactions between arboviruses and their arthropod vectors is that vector hosts become increasingly resistant to parasites; parasite attenuation occurs; or through the process of coevolution, resistance and attenuation occur in concert. Detrimental effects from arboviruses are only seen when vector and virus are not yet well adapted. Results from this study indicate th...

The lack of high-throughput, low-cost surveillance techniques is a serious impediment to effective control and prevention of mosquito-borne diseases worldwide. Here, we demonstrate that mobile phones are a powerful tool for probing mosquito populations through their species-specific wingbeat acoustic signatures. We establish that a wide range of phones, including low-cost models, sensitively ac...

in order to study the mosquito fauna of iran, and to prepare the temporal as well as the spatial distribution of the iranian mosquitoes, a comprehensive study has started since 1981. in this program in which more than 60.000 mosquito larvae, from different breeding sites has been studied, 15 species of culex are reported. these are;cx. arbieeni, cx. bitaeniorhynchus, cx. deserticola, cx. horten...

Mosquito-borne diseases are responsible for significant human morbidity and mortality throughout the world. Efforts to control mosquito-borne diseases have been impeded, in part, by the development of drug-resistant parasites, insecticide-resistant mosquitoes, and environmental concerns over the application of insecticides. Therefore, there is a need to develop novel disease control strategies ...

Control of aedine mosquito vectors, either by mosquito population reduction or replacement with refractory mosquitoes, may play an essential role in the fight against arboviral diseases. In this review, we will focus on the development and application of biological approaches, both natural or engineered, to limit mosquito vector competence for arboviruses. The study of mosquito antiviral immuni...

BACKGROUND & OBJECTIVES An efficient larvivorous fish must show a predilection for mosquito larvae in the presence of alternative preys. This study compares the feeding capacity and preference of Aphyosemion gularis exposed to different kinds of aquatic macroinvertebrates. METHODS Various prey organisms such as Anopheles larvae and pupae, Culex larvae, chironomid larvae and ostracods were eit...

Vector control is the main means of preventing and controlling some parasitic pathologies (malaria, dengue, chikungunya ...). This strategy is mainly focused on reducing contact between human/ vector. This protection is through the use of insecticide-treated mosquito nets, the wearing of long, clear and covering clothes but by using mosquito repellents such as body products, sprays or coils. Th...

We analyzed the phylogenetic tree of densoviruses isolated from indigenous mosquitoes and mosquito cell lines. Our findings suggest two distinct clades of densovirus. The viruses in the first clade were isolated from an indigenous mosquito which had the Aedes aegypti densovirus (AaeDNV) as a representative virus. The other clade of viruses was isolated from mosquito indigenous cell line which h...

Insecticide treated nets (ITNs) represent a powerful means for controlling malaria in Africa because the mosquito vectors feed primarily indoors at night. The proportion of human exposure that occurs indoors, when people are asleep and can conveniently use ITNs, is therefore very high. Recent evidence suggests behavioral changes by malaria mosquito populations to avoid contact with ITNs by feed...

This paper reviews the recorded predators of all life stages of British mosquitoes and assesses their relative effectiveness in limiting mosquito populations. Predators vary markedly in the different habitats that immature and adult mosquitoes frequent, with representatives from at least six insect orders, thirteen arachnid families, as well as crustaceans, amphibians, fish, birds and mammals. ...
