The body size of mosquitoes can influence a number bionomic factors, such as their blood-feeding ability, host attack rate, and fecundity. All these traits are important determinants potential to transmit diseases. Among abiotic biotic high temperature low nutrition in the developing stages generally result small adults. We studied relationship between multiple feeding gonotrophic cycle some fecundity attributes by using three strains two competent vector species, Aedes aegypti (L.)...
We asked whether climate change might affect the geographic distributions of Aedes aegypti (L.) and albopictus (Skuse) (Diptera: Culicidae). tested effects temperature, diet presence congeneric species on performance immature stages these two aedine in laboratory. Mosquitoes three different species‐density combinations were reared at four constant temperatures (20 °C, 25 30 35 °C) low‐ or high‐level diets. Of tested, mortality increased only °C both species. Mortality was higher than...
The relationship between climatic factors and mosquito abundance is very important to determine parasite activity levels and, therefore, disease risk. Therefore, this study was conducted investigate the seasonal of anophelines their association with meteorological variables transmission in two malaria endemic areas Bangladesh. Monthly sampling done from both indoors outdoors 12 selected houses using light traps (LTs) pyrethrum spray (PS) during January, 2011 2012 Outdoor rainfall,...
The western Kenya highland has been experiencing dramatic landuse changes in the past three decades. Landuse change hypothesized to be one of mechanisms for malaria epidemics African highlands because it can alter physical and chemical characteristics mosquito breeding habitats. One important is deforestation. current study examined effects forestation or deforestation on survivorship Anopheles gambiae larvae colonization other aquatic insects larval habitats Kakamega forest (elevation...
Experiments, using the capture-mark-release-recapture technique inside large nets, were carried out in Chiang Mai, northern Thailand, to examine heterogeneity host preference of Japanese encephalitis (JE) vectors. A significantly higher proportion vector species that initially attracted a cow fed when released into net with than containing pig. However, Culex vishnui individuals had been pig feeding rate rather cow. When mosquitoes given choice by being both animals, they exhibited tendency...
Blood-feeding patterns of mosquitoes are crucial for incriminating malaria vectors. However, little information is available on the host preferences Anopheles in Bangladesh. Therefore, objective present study was to determine hematophagic tendencies anophelines inhabiting a malaria-endemic area Adult were collected using light traps (LTs), pyrethrum spray (PS), and human bait (HB) from village (Kumari, Bandarban, Bangladesh) during peak months transmission (August-September). Enzyme-linked...
Novel and practical methods are always sought across all disciplines; within bioaerosol research, portable, lightweight, low-cost sampling pumps few far between. Fungal spores, key components of bioaerosols, have attracted attention due to their negative effects on human populations, agricultural systems, ubiquitous nature. In terms spatial scales, fungal spores vertical gradients frequently overlooked in cases where atmospheric samples collected, they often a large distance away from the...
<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 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...
1. In nature various mechanisms that provide some refuges for inferior species to escape from competition act together promote the coexistence in a local community. We propose method evaluate simultaneously relative importance of different coexistence, focusing on mycophagous drosophilid community depending multispecies fungal host system, where two – aggregation over patches single and resource partitioning at level can together. The data are based numbers adult insects emerging naturally...
Although larvae feeding and food source are vital to the development, survival population regulation of African malaria vectors, prey organisms Anopheles gambiae in natural environment have not been well studied. This study used a molecular barcoding approach investigate diets s.l. western Kenya. Gut contents from third- fourth-instar habitats were dissected DNA was extracted. The 18S ribosomal gene amplified, resulting clones screened using restriction fragment length polymorphism method...
Anopheles gambiae is the predominant malaria vector species in Ghana, western Africa, with a strong local presence of melas Theobald along southern coast. We studied biting behavior these two complex inland and at coast special attention to peoples' preference for outdoor sleeping. collected mosquitoes sites 2007, representing moist semideciduous forest zone strand mangrove zone, sampling was repeated dry rainy seasons. Sampled were examined species, parity size (wing length), we identified...
Multiple blood feeding (MBF) in a gonotrophic cycle vector mosquitoes influences pathogen transmission by increasing host-vector contact. meals can be caused malnutrition the larval stage, harsh environment adult or interrupted due to host defense. We focused on effect of body size MBF two mosquitoes, Aedes aegypti (L.) and albopictus (Skuse), laboratory, using small large adults both species. Most females (94.3% Ae. 88.2% albopictus) oviposited with first meal. There was no relationship...
We compared climatic distribution ranges between Aedes albopictus (Skuse) (Diptera: Culicidae) and the five wild (nondomesticated) species of Albopictus Subgroup Scutellaris Group (Stegomyia) in southern Asia. Distribution sites concentrate seasonal forest savannah climate zones India, Indochina, China. The Ae. is broader than under 1) tropical rain-forest climate, 2) steppe temperate 3) continental with large temperature variation (hot summer cold winter) at lowlands (northernmost 40°N vs...
Anopheles stephensi is an Asian and Middle Eastern malaria vector, it has recently spread to the African continent. It needed measure how parasite infection in A. influenced by environmental factors predict its expansion a new environment. Effects of temperature food conditions during larval periods on mortality, period, female wing size, egg production, adult longevity, rate were studied using laboratory strain. Larval survival size generally reduced when reared at higher temperatures with...
