Mosquiotes are a menance from time immemorial. Diseases transmitted by mosquitoes are prevalent all over the world and it is a serious issue of concern. Mosquitoes act as vectors for most of the diseases like malaria, Dengue, yellow fever, dengue fever, chikungunya ferver, filariasis, encephalitis. TMosquitoes act as the most deadliest creatures in the world. They are many species of mosquitoes namely 2700 species of mosquitoes have been reported the three most significant ones are Aedes, Anopheles and Culex.These mosquitoes play a major role in the transmission of various dreaded disesases. Mosquitoes have developed resistance against many of the commercially available repellants. These repellants on routine use cause various health hazards for common man. As an alternate measure pla ecofriendly plant synthesized products can be used to get rid of these mosquitoes. Though they are many reports pertaining …show more content…
UV-Vis spectroscopy
The reduction of silver ions was observed using spectroscopic analysis by measuring the spectral wave length change and observed a peak at 430nm. The spectrum produced due to the bioreduction of silver ions and its Surface Plasmon Resonance (SPR) at room temperature was observed using Thermo UV10 Spectrophotometer at a band width of 1nm.
FTIR Spectroscopy
Silver nanoparticles synthesized solution was centrifuged at 15000 rpm for fifteen minutes to obtain the SNP pellets and redispersed with 1ml of distilled water and allowed to dry to obtain dry powder to enable the FTIR and SEM analysis. odered Silver nanoparticles were subjected to FTIR analysis to find the possible interaction of silver and
1. How does the kissing bug (e.g., Rhodnius sp., Triatoma dimidiate ) locate its human prey?
Head lice live in furniture and towels so it is advisable to spray furniture after purchase to prevent the spread. For the case of beddings , towel and other clothing’s, you should soak and clean them in hot water then dry heat them in a drier .Seal them in plastic bags for two weeks to prevent further
Native Silver, or more commonly know as just “silver,” is a mineral that is created from the element silver (also called Argentum; abbreviated on the periodic table as Ag). It is seldom found as a native element mineral. Instead, it has tendencies to mix together with other minerals such as quartz, gold, and copper.1 11 Silver is actually not really reactive. It is even considered one of the “noblest” of the transition metals, noblest meaning “least chemically reactive.”5 In fact, it is used in many dishes as a fancy garnish that is able (and sometimes meant) to be eaten. Native silver also has one of the highest conductivity rates, both electrical and thermal, of metals. Because of this property, it is used in many electronic circuits as a thin coating.5 Due to its shiny, lustrous quality, native silver is also used for jewelry, decorations, and ornaments.
In Mosquitoland by David Arnold, not only do the settings have effects on the plot/characters, but major or minor events do too. Without some of the following events, the plot would have been altered and would clearly not be the same.

The seventh major case of Endangered Specie. Specific species of mosquito play host to one phase of various disease organisms they are the cause of major diseases that lead to human compilation. Most people don’t find it wrong to wipe the entire mosquito species in other to prevent human diseases such as sleeping sick, malaria, and human
Smallpox is a disease from the variola virus. Smallpox has caused an estimated number of 300 million deaths in the 1900s alone. Smallpox is said to have been around since the ancient Egyptian times. The disease was eradicated in the late 20th century and two samples are still kept, one in U.S.A and one in Russia. Smallpox creates bumps and blisters all over the body and has been one of the most fatal epidemics the world has seen.

Nearly half a billion people are infected with malaria each year and more than a million people die from this disease. Malaria is transmitted through the bite of a female Anopheles mosquito infected with malaria parasites. When the parasites enter the human body, it slowly destroys the body’s red blood cells, eventually killing the patient if left without undergoing immediate treatment (Stanmeyer 2007). One of the means employed to counter the spread of malaria is through the use of DDT as an insecticide to kill the mosquitoes before they are able to infect more people.
Am. Chem. Soc. 2012, 134, 13212−13215). First, 20 mL nanopure water (18.2 MΩ) was boiled with a constant stirring in a 25 mL RB flask fitted with condenser. 778 µL of 3.8 mM H2PtCl4.6H2O (chloroplatinic acid) was added to the boiling water. After 1 minute, 244 µL of solution containing 38 mM trisodium citrate and 2.6 mM citric acid was injected at once into the solution. Without further waiting, 122 µL of 21 mM sodium borohydride solution was mixed into the boiling solution. Within 10-60 s colorless solution turned into blackish solution showing the evidence of formation of citrate capped ~4 nm size platinum seed particles. This method is a standard protocol to prepare seed platinum nanoparticles, therefore, these NPs were used without
Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.

Dengue is the most common arboviral (arthropod-transmitted) disease and it also position as the most important mosquito-borne viral disease in the world. Approximately 2.5 billion people living in tropical and sub-tropical regions are at a great risk of dengue infection, which is almost equal to about two-fifths of the human population (Gubler & Clark, 1995; WHO, 2009). There is an estimated 50-100 million infections occurring globally in each year, with 500,000 cases requiring hospitalization and causing 24,000 deaths (Halstead, 1988; WHO, 1997). Furthermore, the increasing populations in tropical and sub-tropical regions, making dengue as a global threat to public health (UNEP 2009; Holden, 2009).
