In the past decade there has been a significant reduction in malaria incidence globally. In some places continuous surveillance has indicated that the reduction in malaria cases has been sustained to the point of near elimination. The drastic reduction in malaria cases may be attributed to the unprecedented financial support to national malaria control programmes by several donors. The use of i...
The monitoring of the mosquito population for the purpose of possible better mosquito control took place in Osijek from 1995-2004. For the period of ten years, the primary research method for monitoring the mosquitoes used was dry ice baited CDC-traps. This provided significant information on mosquito species, their dynamics and seasonal activity. In total, 207,136 mosquito specimens were colle...
Mosquito control evaluations of the granular formulation of 0.5% pyriproxyfen were undertaken in marshes and a pond in Busan during the period of July through September, 2001. In marsh condition where Culex pipiens pallens were predominantly breeding, the treatment of pyriproxyfen produced over an average of 95% mosquito larval reduction at a concentration of 0.05 mg/l for the first 4 weeks in ...
Malaria is still a major public health problem. In India nearly 2-3 million cases occur every year with about 1000 deaths. Control of malaria requires case detection and treatment of affected individuals, and for curtailment of malaria transmission, control of mosquito vectors is undertaken. Vector control requires knowledge of the ecology of breeding and resting habitats and behaviour of vario...
Croatian fauna consists of 50 mosquito species, and 15 of them have medical importance. Only 10 species are capable of transmitting the West Nile Virus (WNV). In Croatia the most capable vector is Culex pipiens c. According to species distribution and abundance all of Croatia is a risk area for WNV transmission. Culex pipiens c. is the dominant species (share of 5-10%) in eastern Croatia, but C...
The disease environment could help explain underdevelopment in Africa. This paper shows that local malaria risk is associated with worse local development outcomes. Combining an Ethiopian household survey with satellite-derived topographical information, the paper shows that malaria incidence is correlated with village elevation, slope, and their interaction. That is, malaria is sensitive to el...
Mosquitoes (Diptera, Culicidae) occur in natural, urban, and peri-urban areas throughout the globe. Although the characteristics of urban and peri-urban habitats differ from those of natural habitats in many ways (e.g., fragmentation, pollution, noise, and light), few studies have examined the population connectivity of mosquitoes in urban areas. To obtain an overview of the species composition...
Sex-biased dispersal is often explained by assuming that the resource-defending sex pays greater costs of moving from a familiar area. We hypothesize that sex-biased dispersal may also be caused by a sex bias in breeding site availability. In avian resource-defense mating systems, site availability is often more constrained for females: males can choose from all vacant sites, whereas females ar...
Global climate change has the potential to alter aquatic communities through changes in evapotranspiration and increased variability in precipitation. We used aquatic mesocosms to test the impacts of variable precipitation on population dynamics of common mosquito (Culicidae) and midge (Chironomidae) larvae that inhabit vernal pools. In a mixed deciduous forest in northern Vermont, USA, we orth...
