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
In the article “When Mosquitoes Were Killers in America” by Lauren Tarshis, She makes the statement “Yet mosquitoes are far more than a nuisance.” What she means is that mosquitoes aren't a little bug that just sucks a little blood and can be annoying, but instead it uses all that and more. Mosquitoes have killed millions upon millions of people by spreading disease like malaria. An example of how she supports this claim is in the article, she says “ In this way, bite by itchy bite, 212 million people are infected with malaria every year” (Tarshis 13). And that is only a year with bug spray, shots, and all the other things that help stop mosquitoes. So when the U.S. government tried to save people from these murders little insects. So they
The nano-thermal analysis method is capable of studying the specific regions of a sample irrespective of its composition. In a multi-component sample, the analysis methods make it possible for the researchers to distinguish between the different components and identify the different characteristics found in each of the sample (Craig, 2002). During the analysis of any sample, the nano-thermal method does not necessarily require the physical alteration of the sample. In its place, it is capable of analyzing any sample through surface studies.
The Asian Tiger Mosquito looks very similar to our common, everyday mosquitos except for a few differences. This six-legged insect averages a length of about ten millimeters. The abdomen of this species is black with white horizontal bands. These white bands are also found on the legs and have white tips on the palp. The thorax is also black and the dorsal side of the thorax has a white stripe down the center, starting at the back of the head and continues along the thorax.
Who would guess that the world’s deadliest animal family is the mosquito? They have been biting people and animals for about 210 million years. They can transmit the West Nile virus, yellow fever, Zika virus, canine heartworms, and malaria. One million people die every year from just malaria.
question I thought of was, is he the only giant on the planet? This was
A question commonly associated with the word insecticides is, what are they? Well I have the answer, insecticides are chemicals that are used to eliminate insects. In the agricultural industry, insecticides are classified into different categories,and the most used is carcinogenic. A carcinogenic insecticide is a substance or agent producing or causing cancer. This is just one of the reason that I believe there are more cons then pros when dealing with a insecticide.. When I was a kid , I can remember my parents taking me and my brother an apple orchard and picking apples. I couldn't wait to eat them until I got home, but we couldn't eat an apple because of what insecticides could be on the apple
In 1665, in the Kingdom of England, there was a great disease going through the kingdom that killed over 100,000 people, it was passed throughout the population by tiny bugs that were everywhere and were nearly impossible to avoid. This epidemic is known as the Great Plague of London, 1665 and it is the strand of the Bubonic Plague that tore through London, killing about 15% of London’s population which was around 100,000 people. This Plague was one of the worst diseases to tear through Europe in the 1300’s - the 1600’s. It hit England especially hard because they were on an island and had to where to go and couldn't avoid the spreading of the disease.
1. How does the kissing bug (e.g., Rhodnius sp., Triatoma dimidiate ) locate its human prey?
Yellow Fever is a viral infection that is caused from the bite of an infected female mosquito, they are mainly found in areas of Africa and South America. There are three main types of the Yellow Fever virus: Sylvatic yellow fever, Intermediate yellow fever, and Urban yellow fever. Sylvatic yellow fever also known as jungle yellow fever is started by mosquitoes breeding in tree holes in areas, such as banana plantations; monkeys become infected when they are bitten by an infected mosquito, it continues to spread as uninfected mosquitoes bite and infected monkeys; then the process comes to humans where they become exposed to the virus when they are bitten by and infected mosquitos. The intermediate cycle are only in Africa and is also called
Malaria in humans is caused by four species of protozoa, sophisticated one-celled organisms, that can infect red blood cells. These four species are called Plasmodium falciparum, plasmodium vivax, plasmodium malariae, and plasmodium ovale. The worst cases are caused by the Plasmodium falciparum species, which is also the species with the most resistance to drugs. To contract malaria, a mosquito, but not just any mosquito must bite a human. The only type of mosquito that can infect humans with the malaria virus is the Anopheles mosquito. While there are...
A hidden threat against the USA is becoming more and more potentially catastrophic; bioterrorism is now almost unstoppable. With new technologies such as genetic engineering, pathology, and high tech electronics, an attack of bioterrorism could have a record breaking number of fatalities. The truth of the matter is that this is real and very dangerous. There are secret bioweapon research facilities all across the world being hidden right under our noses. The threat of bioterrorism against the USA is greatly increasing and going unnoticed; as a response, we need to take action to be prepared for this catastrophic event.
If you had a choice between a burger and a bowl of crickets, I think I would know which you choose to eat. As disturbing as this sounds, in the near future we may not have that choice. With our annual protein consumption rising, and Europe’s protein sources decreasing, coupled with a growing population, we may have only one alternative… Insects.
The causative agent of the dengue disease is the dengue virus (DENV), a group of four flaviviruses that are closely related but antigenically distinct. They are hypothesised to have evolved independently from ancestral sylvatic viruses between 100-1,500 years ago (Wang et al., 2000). The four groups are known as serotypes and denoted as dengue virus type 1 (DENV-1), dengue virus type 2 (DENV-2), dengue virus type 3 (DENV-3) and dengue virus type 4 (DENV-4).
Dengue fever, also known as the “breakbone fever”, is a vector-borne viral disease endemic in tropic and subtropic regions, with around 100 million symptomatic new cases each year worldwide15. It is caused by any one of the four closely-related serotypes or viruses that is spread by multiple species of mosquitoes, in particular the Aedes aegypti 6,13.
