Several arboviruses have emerged and/or reemerged in the New World past decades. Zika and chikungunya viruses, formerly restricted to Africa perhaps Asia, invaded continent, causing great concern. Dengue virus outbreaks continued occur almost all countries, with millions of cases per year. West Nile rapidly North America, now been found Central South America. Other arboviruses, such as Mayaro Eastern equine encephalitis increased their activity new regions. Changes pathogenicity documented...
According to WHO, in 2021, there was an estimation of 247 million malaria cases from 84 malaria-endemic countries. Globally estimated count 2 billion and 11.7 deaths due were recorded the past two decades. Further, emergence drug-resistant mosquitos threatens mankind. Therefore, development newer larvicidal agents is need hour. This research identifies a new series variably substituted indolizines for their effectiveness controlling Anopheles arabiensis larvae through activity. The Ethyl...
This study aimed to assess the vertical patterns of oviposition and temporal changes in distribution mosquito species an area Atlantic Forest Rio de Janeiro State, Brazil, particular, behavior potential yellow fever virus vectors. Mosquito samples were collected from Ecological Reserve Guapiaçu (REGUA, Brazil), which includes a somewhat disturbed forest, with large diversity plants animals. In all, 5,458 specimens (ten seven genera) collected. Haemagogus leucocelaenus was most frequently...
Greener synthesis of a series novel indolizine analogues have been achieved by the cyclization aromatic cycloimmonium ylides with electron‐deficient alkynes in presence water as base and solvent at 80 °C. Yield title compounds was good reactions performed were eco‐friendly. The structures these newly synthesized confirmed spectroscopic techniques such FTIR , NMR LC ‐ MS elemental analysis. Characterized evaluated for larvicidal activity against Anopheles arabiensis standard WHO assay using...
Water-holding tree holes are main larval habitats for many pathogen vectors, especially mosquitoes (Diptera: Culicidae). Along 3 years, the diversity and composition of mosquito species in two neighbouring but completely different environments, a city its adjacent forest, were compared using generalized linear mixed models, PERMANOVA, SIMPER association indexes. The area (Northwest Argentina) is highly relevant epidemiologically due to presence Aedes aegypti L. (main dengue vector)...
A temporal observational study was conducted of the Culicidae fauna in a remnant area Atlantic Forest within private reserve (Guapiaçu Ecological Reserve-REGUA) presenting typical vegetation cover dense rain forest, with some patches recovering floristic composition similar to that original community. Research carried out analyze influence climatic factors (mean monthly temperature, rainfall, and air relative humidity) on dynamics mosquito communities occur reserve. The completeness...
Mosquitoes are the major vectors of parasites and pathogens affecting humans domestic animals. The widespread development insecticide resistance negative environmental effects most synthetic compounds support an interest in finding developing alternative products against mosquitoes. Natural coumarins coumarin analogues known for their several pharmacological properties, including being insecticidal. In present study halogenated (3-mono/dibromo acetyl, 6-halogenated analogues) were screened...
Members of the genera Haemagogus and Sabethes are most important biological vectors wild yellow fever virus (WYF) in forested areas Americas. The ecologies janthinomys, Hg. leucocelaenus, chloropterus, Sa. glaucodaemon were studied a forest Chapada dos Guimarães National Park, state Mato Grosso, Brazil, to evaluate influence climatic factors (temperature relative humidity [RH]) on their abundance. We also examined association climate with landscape structure species distribution patterns...
Aedes aegypti (L.) (Diptera: Culicidae), the main vector of dengue and urban yellow fever in world, is highly adapted to human environment. Artificial containers are most common larval habitat for species, but it may develop tree holes other phytotelmata. This study assessed whether San Ramón de la Nueva Orán, a city located subtropical montane moist forest where outbreaks occur, relevant as Ae. if species be found natural areas far from habitations. Water holding were sampled during 3 years...
The effect of multiple immersions on Haemagogus janthinomys , leucocelaenus Aedes albopictus and Ochlerotatus terrens eggs was studied. Eggs were collected in April, June, October December 2011 Minas Gerais, Brazil. Most the hatched upon first immersion, while showed a varied instalment hatching response. number required for increased closer to dry winter season.
To increase the knowledge of biodiversity and identify larval habitats used by immature mosquitoes in Atlantic Forest, we conducted a study areas with various stages preservation within Guapiaçu Ecological Reserve Cachoeiras de Macacu, Rio Janeiro state. The Culicidae fauna were sampled during February, April, June, August, October, December 2012; March, May, 2013; January March 2014. Immature collected dippers suction tubes (mouth aspirators). Over sampling period, 2697 larvae 56 species...
Malaria, affecting all continents, remains one of the life-threatening diseases introduced by parasites that are transmitted to humans through bites infected Anopheles mosquitoes. Although insecticides currently used reduce malaria transmission, their safety concern for living systems, as well environment, is a growing problem. Therefore, discovery novel, less toxic, and environmentally safe molecules effectively combat control these vectors in high demand. In order identify new potential...
Abstract The current global increase in prevalence of vector borne diseases, as well an expansion tropical infections to more temperate zones, justifies further studies on populations. Urban areas may favour viral transmission humans through close contacts between the vectors and vertebrate hosts, also affecting mosquito populations by offering larval habitat, refuges adequate microclimates survive winter. This work analyses spatial distribution potential mosquitoes relation landscape...
Eight novel dihydropyrimidine analogs named DHPM1-DHPM8 was synthesized in their hydrochloride salt form using one pot synthesis between methyl 2-chloro-4-(4-chlorophenyl)-6-methyl-1,4-dihydropyrimidine-5-carboxylate and substituted arylamines isopropanol. The antimosquito effect of the test compounds were assessed against adult mosquito Anopheles arabiensis. For adulticidal properties sprayed onto ceramic tiles screened cone bio-assay method. larvicidal activity tested by monitoring larval...
