Evarcha culicivora, a jumping spider from East Africa, specialises in feeding indirectly on vertebrate blood by choosing blood-carrying mosquitoes as preferred prey. Previous studies have shown that this predator can identify its preferred prey by sight alone and also by odour alone. Here we investigate how vision and olfaction work together. Our findings show that, for E. culicivora, cross-mod...

Although they provide a number of valuable ecological services, wetlands also may harbor mosquitoes that are vectors of human pathogens. During 2002 and 2003, we measured biological (i.e., abundances of mosquitoes, other insects, and total heterotrophic bacteria, vegetational cover, and dead organic material), chemical (i.e., pH, dissolved nitrate, dissolved nitrite, dissolved phosphate, total ...

Malaria transmission begins with the injection of Plasmodium sporozoites into the skin of a vertebrate host by infected anopheline mosquitoes. Although the size of the sporozoite inoculum likely affects the course of the disease, the number of sporozoites injected by infected mosquitoes has not been determined in vivo. Using a quantitative PCR assay, we determined the number of sporozoites inje...

During the present study, the host–parasite relationship between mosquitoes and parasitic mites was investigated. The 8954 individuals of male and female mosquitoes belonging to 26 genera: seven each of Aedes and Culex, six of Anopheles and one each of Toxorhynchites, Coquillettidia and Uranotaenia were collected from 200 sites. The male and female mosquitoes were collected from the State of Ut...

Individual female mosquitoes from field populations of Aedes aegypti, Culex nigripalpus and Coquillettidia perturbans were analyzed for sugar, glycogen and lipids. Controls were maintained in the laboratory for 7 to 10 days on 2% and either 10 or 20% sucrose. Mosquitoes held in the laboratory had significantly more glycogen and lipid than field-collected mosquitoes of the same species. Laborato...

Mosquito-borne diseases are increasingly being recognized as global threats, with increased air travel accelerating their occurrence in travelers and their spread to new locations. Since the early days of aviation, concern over the possible transportation of infected mosquitoes has led to recommendations to disinsect aircraft. Despite rare reports of mosquitoes, most likely transported on aircr...

in the previous studies by foreign investigators on culicinae fauna of iran two culiseta, cs. longiareolata and cs. annulata; one coguillettidia, cog. richiardii, and one uranotaenia species, ur. unguiculata have been reported. in the comprehensive study of the culicinae fauna of iran, made by the school of public health, teheran university, since 1980, not only all named species, except one, w...

background: bromeliads can be epiphytic, terrestrial or saxicolous and use strategies to allow water to be re­tained in their leaf axils, where various arthropods can be found. these include mosquitoes, whose larvae are the most abundant and commonly found organisms in the leaf axils. the objective of this study was to look for im­mature forms of mosquitoes (the larval and pupal stages) in brom...

background: mosquitoes transmit several diseases to human. there are several measures for control of larvae. as part of integrated vector management (ivm) program, the utility of floating layers of polystyrene beads (eps) is a po­ten­tial alternative in habitats of mosquito larva. eps beads prevent oviposition of mosquito as well as killing the im­ma­ture stages by forming a tick layer on the w...
