background: to study the chemical constituents and larvicidal activity of essential oil extracted from the leaves of coccinia grandis against three mosquito species. methods: essential oil was extracted by hydro distillation using clevenger apparatus and was analyzed for chemical constituents by gas chromatography-mass spectrophotometry (gc-ms). larvicidal activity was recorded after 12 and 24h...

ba ckground: mosquitoes are well known as vectors of several disease causing pathogens. the extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fos- tered environmental deterioration. hence in recent years plants become alternative source of mosquito control agents. the present study assessed the larvicidal and ovipo...

Background: Malaria burden is generally lower in urban settings. Urban malaria likely to surge due rapid and unplanned urbanization. Hence, this study sought determine the prevalence of parasite vectors Adenta-barrier, a suburb Adentan Municipality.
 Methods: The followed cross sectional design pattern. Mosquitoes were collected from 40 houses site using pyrethrum spray catches (PSC) metho...

background and aims: elastomeric chains and niti coil springs are two major traction aids in orthodontic tooth movements. force degradation occurs over time in both groups, with higher percentages in elastic chains. the effects of environmental factors and some mouth rinses on this force decay have been previously studied. no study has been performed to evaluate the effect of current popular mo...

RATIONALE It is not clearly evident whether malaria affects the poor more although it has been argued that the poor bear a very high burden of the disease. This study explored the socioeconomic and geographic differences in incidence and burden of malaria as well as ownership of mosquito nets. METHODS Structured questionnaires were used to collect information from 1657 respondents from rural ...

introduction: neural stimulation is a promising new technology for the treatment of medically-intractable seizures.  transcranial magnetic stimulation (tms) is a simple, non-invasive, low cost technique which is widely used in neurophysiology. in a few studies that have been performed at different frequencies the therapeutic effects of this technique were not obvious. repetition of low frequenc...

background: dengue is amongst the most serious mosquito-borne infectious disease with hot spots in tropical and subtropical parts of the world. unfortunately, no licensed vaccine for the disease is currently available in medicine markets. the only option available is the management of dengue vector mosquito, aedes aegypti (diptera: culicidae). method: predatory potential of five odonate nymphs ...

background: orang primary health centre (ophc) and balipara primary health centre (bphc) of assam (india) report mosquito borne diseases annually. current study was performed to ascertain the prevalence of known malaria and japanese encephalitis (je) vectors and their possible role in disease transmission. methods: malaria epidemiological data for 2006–2010 and je data for 2008–2013 of assam, i...

b a ckground: the aim was to survey the specific factors, which cause to decrease blood feeding of mosquitoes important to succeed vector control. m e t hods: larval collection was carried out from fixed and variable breeding places of yazd county, central iran in 2009. autogeny-anautogeny, stenogamy-eurygamy, and blood preference of culex pipiens were studied using standard mosquito cages bloo...
