In human they mainly occupy the intestine or blood. Plasmodium falciparum cause severe malaria than other plasmodium species (vivax, ovale and malaria) and are transmitted by Anopheles mosquitoes, whereas dengue is transmitted by the bite of female mosquito Aedesaegypti. Infection with malaria parasites may result in a wide variety of symptoms, ranging from absent or very mild symptoms to severe disease and even death. This study is aimed to provide the awareness about two epidemic disease i.e. malaria and dengue. We have done a survey on population of Karachi (sample=200 and age group=15 to 50 years) presented at schools, colleges, universities and other professionals and common places. The survey was accomplished using common questions generally on malaria and dengue. Data analysis of current survey shows that 164 people were infected of malaria in a population of 200 which makes 82% hence here we can also conclude that catching the disease risk ratio is high. This research highlights the need for training and education about malaria and misjudgment of it with dengue. Nowadays malaria is not a life threatening disease it is curable with proper regimen by maintaining hygienic and health environment and preventions.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70858956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 1500 Adult female culicines were used for the tests. Mosquitoes from Gombe State University showed 96%, 63%, and 66% susceptibility to Alphacypermethrin (0.75%), Bifenthrin (0.15%) and Bendiocarb (0.1%) respectively. The mosquito samples from Dawaki quarters indicated 92%, 62% and 69% susceptibility to Alphacypermethrin, Bifenthrin, and Bendiocarb respectively; whereas culicines from New market Area showed susceptibility of 90% to Alphacypermethrin, 44% and 69% to Bifenthrin and Bendiocarb respectively. No full susceptibility to any of the chemicals was observed; however, percentage mortality to Alphacypermethrin in all the sites suggests the possibility of resistance that needs to be confirmed but results for Bifenthrin and Bendiocarb indicates resistance of the mosquitoes in all the study sites. In view of this, it is important to implement insecticide resistance monitoring strategy in Gombe State.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70858792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Larvaecidal study was conducted as per standard method. It was recorded that blue colour of copper sulphate changes to reddish colour in aqueous medium. The Surface Plusmon Resonance (SPR) for marigold and sunflower mediated CuNPs shows absorption at 374 nm and 315 nm, respectively. SEM and phase contrast micrograph picture showed that CuNPs are spherical in nature. Moreover, FTIR spectra indicate the different functional groups of biomoleculs involved in the formation and stabilization of CuNPs. Results also revealed that synthesized nanoparticles showed mosquito larval mortality rate 98.8 % and 70 % with marigold and sunflower mediated CuNPs, respectively.  Present results suggest that green synthesis of CuNPs has immense potentiality to kill the mosquito larvae of  Culex quinquefasciatus.

They are widely distributed in both tropical and temperate regions of the world. Mosquitoes are strongly attracted to humans and are especially adapted to breeding in places created by human activities. Methods: Survey of mosquito larvae in both open and closed habitats was carried out in Aguleri between the months of March and June, 2014. Random sampling method was used in selecting the communities surveyed as well as the identified breeding sites in the study area. Collection of mosquito larvae was done with either the use of larval net or dipper method depending on the nature of the habitat encountered. Open habitats where mosquito larvae were collected included ground pools, gutter, domestic water containers, other containers that can hold water and banks of rivers and streams. The closed habitats where mosquito larvae were collected included toilets/bathroom floors and broken septic tanks. Results: A total of four hundred and twenty nine mosquito larvae belonging to three different genera were identified in the study area. They included:  Aedes aegypti  (39.9%),  Ae. albopictus  (19.6%),  Ae. circumlutoelus  (1.2%),  Anopheles gambiae  (18.9%),  An. funestus  (1.4%),  An. moucheti  (1.6%),  Culex quinquefasciatus  (13.1%) and  Cx. tigripes  (4.4%). In open larval habitat, the three genera of mosquitoes identified were present whereas in the closed habitat, only two genera (Culex and Aedes) were present. Also, all the eight different species of mosquito collected were found in the open larval habitat; only two species ( Aedes aegypti  and  Culex quinquefasciatus ) were identified in the closed habitat. The equitability or evenness of individuals' distributions among the three genera collected in the survey is relatively high (ED=0.75). However the distribution of the species is not even (ED=0.49).  Ae. aegypti  and  Ae. albopictus  tend to be more abundant and use almost all the breeding sites encountered. Conclusion: This is a useful indicator of the risk of mosquito borne diseases transmission in the study area. The information provided by this research would be helpful in planning and implementation of larval control approach as a method of mosquito control. This is because the breeding sites identified favour the survival of one or more species of mosquito.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70858930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four concentrations ranging from 0.25 to 2 g/L were performed for all extracts and fractions in single and combined forms. In single form of L. camara , the LC 50 values of solvent extracts and fractions were ordered as follows: 0.62>0.72>0.96>2.20>3.36 g/L for ethyl acetate, hexane, methanol crude, chloroform and methanol, respectively. For O. gratissimum the following order of LC 50 values was observed: 0.37>0.60>0.97>1.60>3.23 g/L for hexane, methanol crude, ethyl acetate, chloroform and methanol, respectively. Methanol crude extract, hexane and ethyl acetate fractions were selected to form five combinations in 1:1 ratios.
