In the Old World, some mosquitoes in Culex pipiens complex are excellent enzootic vectors of West Nile virus, circulating virus among birds, whereas others bite mainly humans and other mammals. Here we show that, northern Europe, such forms differing behavior physiology have unique microsatellite fingerprints with no evidence gene flow between them, as would be expected from distinct species. United States, however, hybrids these ubiquitous. Such human-biters bird-biters may bridge...
Abstract Understanding the mechanisms of adaptation to spatiotemporal environmental variation is a fundamental goal evolutionary biology. This issue also has important implications for anticipating biological responses contemporary climate warming and determining processes by which invasive species are able spread rapidly across broad geographic ranges. Here, we compare data from historical study latitudinal in photoperiodic response among Japanese U.S. populations Asian tiger mosquito Aedes...
Since 1988 malaria epidemics have occurred in multiple sites western Kenya highlands. Climatic variability has been associated with some of the recent epidemics. We examined influences climatic factors on distribution and abundance three vector species, Anopheles gambiae, arabiensis, funestus Great Rift Valley. Mosquito samples were collected from lowland highland areas various conditions. The species abundant lower part Kenya. An. arabiensis was not found above 1,400 m elevation Although...
Anopheline larval habitats associated with a swamp, were examined in highland area (1910 m elevation) of western Kenya. A significant association was found between occurrence Anopheles gambiae Giles s.s. (Diptera: Culicidae) larvae and two factors, habitat size vegetation type. Over 80% An. small isolated pools, characterized by short plants, occurring both swamp margins roadside ditches. However, not marked papyrus floating plants. The warmer daytime temperatures water, which significantly...
Introduction of potential disease vectors into a new geographic area poses health risks to local human, livestock, and wildlife populations. It is therefore important gain understanding the dynamics these invasions, in particular its sources, modes spread after introduction, vectorial potential. We studied population genetics Aedes (Finlaya) japonicus (Theobald), an Asian mosquito that was recognized for first time United States 1998. examined patterns genetic diversity using random...
Abstract Survival in three humidity conditions was studied for diapause and non‐diapause eggs of 4 species Aedes (Stegomyia) mosquitoes which use small containers as larvae. In general, survived longer than did eggs. Diapause A. albopictus , prefers disturbed habitats outside forests oviposition, were more resistant to severe desiccation those forest ( riversi, galloisi, flavopictus ). Desiccation resistance during hibernation is apparently related the risks associated with different habitats.
A model for a vector mosquito population with two bloodmeal hosts (man and domestic animal) was developed to study the influences of animals on frequency bites man endemicity human malaria. The model, including blood-feeding success in adult stage (depending host density biting efficiency) density-dependent regulation larval stage, combined Ross-Macdonald malaria transmission model. Model analyses suggested that introduction easily fed upon by mosquitoes increases and, some situations,...
<title>Abstract</title> Mosquitoes harbour diverse bacterial communities that are influenced by a number of factors, e.g., geography, host species, and developmental stage. Understanding these microbiotas is crucial for assessing their role as vectors in pathogen dissemination. Here, we compared the <italic>Aedes albopictus</italic> japonicus</italic> across eight countries: six Europe, plus USA Japan, from both adults larval stages when possible, using 16S rRNA amplicon sequencing. We found...
ABSTRACT. Aedes aegypti (L.) and albopictus (Skuse) were surveyed using ovitraps in residential areas Chiang Mai, northern Thailand. Egg populations (both species inclusive) remained low the dry season, but increased/decreased exponentially during first/latter half of rainy respectively. This seasonal pattern was similar to distribution dengue haemorrhagic fever cases area. During season (November–March) Ae. dominant urban indoor ovitraps. With onset April, relative abundance increased rural...
Abstract The temporal fluctuation of water levels and the presence mosquito larvae were investigated for four types small container habitats (treeholes, bamboo stumps, cemetery stone vases, vessels) on Kabeshima Island in Kyushu, southwestern Japan. probability that containers held was positively correlated with quantity preceding rainfall depth volume containers. It estimated dehydration occurred more regularly autumn winter than summer. present each type habitat stability terms existence...
We used two mitochondrial loci (nicotinamide adenine dinucleotide dehydrogenase subunit 4 and cytochrome oxidase II) a nuclear locus (28S-D2 spacer) for total of 1337 bp to evaluate the relationships among four subspecies Aedes (Finlaya) japonicus Theobald. Ae. j. was recently introduced into United States has been expanding rapidly. also included in our analysis morphologically very closely related species, koreicus Edwards, as well three more distantly species: togoi Theobald, hatorii...
Desiccation survival times of adult mosquitoes were studied for yellow fever mosquito, Aedes aegypti (L.) (6 strains), Asian tiger Ae. albopictus (Skuse) (5 and paullusi Stone & Farmer (1 strain) colonized from South Sulawesi, Indonesia. At both 90 70% RH, males females outlived the other species. The forest species was least resistant to desiccation. Strains urban areas more desiccation than conspecific strains rural villages. When water accessible, females, indicating that death...

Abstract The Asian mosquitoes, Aedes albopictus (Skuse) and japonicus (Theobald), have invaded North America, Europe, other regions since the late 20th century. In invasive ranges, Ae. has well been recognized as urban, domestic species, whereas views about macrohabitats of j. are inconsistent. Previous reports in Japan suggest disappearance from metropolises. However, container-mosquito larvae not inspected simultaneously for various macro microhabitats metropolises Japan. current study...
Abstract 1. A series of laboratory experiments was conducted to examine the influences leaf litter input and flushing medium on priority effects two bamboo‐stump breeding mosquitoes, Aedes albopictus Tripteroides bambusa , using 150‐ml microcosms. Larvae either species were introduced microcosms day 0 (early cohort), at different densities, 14 (late cohort). The early cohort survival, pupation, biomass yield late compared among various combinations treatments (water exchange, addition, both...
Three strains of Aedes aegypti and 3 Ae. albopictus laboratory colonies were reared in different temperatures to compare their development the immature stage (larval pupal periods). The duration developmental times averaged 31.0-32.0 days at 15℃, 13.9-16.6 20℃, 10.2-11.8 25℃ 7.4-8.2 30℃. zero was 8.2-10.6℃ effective cumulative temperature 145-176 degree. For 12.6-15.1 10.0-11.7 7.6-8.4 4.2-8.2℃ 166-214 Male adults emerged 0.2-1.0 faster than females due a difference 4th-instar larval period....
Strategies to eradicate the vector–borne infectious diseases (e.g. malaria and Japanese encephalitis) are often directed at controlling vectors with insecticides. Spraying insecticide, however, opens way for development of insecticide resistance in vectors, which may lead failure disease control. In this paper, we examine whether combined use spray zooprophylaxis can limit mosquitoes. Zooprophylaxis refers control by attracting domestic animals pathogen cannot amplify (a dead–end host). The...
