Battling virus - Dengue, Chikungunya, Zika - transmitted by mosquito’s, on old tire at the time. Clever and highly effective mosquito trap made from the pests' favorite breeding spot! Canadian innovation for killing mosquito eggs could help Dengue, Chikungunya, Zika fight. Researchers use mosquitoes' own perfume to lure them to lay eggs in trap.
A team of innovators from Canada and Mexico have successfully tested a low cost, environmentally-friendly way of destroying the eggs of the mosquito genus that spreads dengue, Chikungunya and the Zika virus.
The editor of this post has by the BCS health department a trap places which is regulary checked and new set by staff from that department.
During the last control the personal found dengue/chikungunya larva.
It might be an good idea to put self a trap up if you have problems with chemicals. Researchers found that 84 ovillantas placed in seven neighborhoods in the town of Sayaxche destroyed more than 18,000 Aedes larvae per month. That’s nearly seven times better than standard traps.
The devices also provide an answer - albeit a very small one - for one of the world’s most intractable waste-disposal problems: What to do with old tires. Moreover, the traps are inexpensive and relatively easy to make and the there’s an almost inexhaustible supply of materials available
The Federal Health Ministry said the lack of citizen participation to keep yards clean and avoid places where water can accumulate in puddles or dirty water is a factor to increase cases of dengue. "I have always said, that the reduction of cases at par and is proportional to the participation of the community, as a community and private institutions become involved it decrease dengue cases by the same proportion." said Garcia, Federal Minister of Health.
The following information is compiled from sources at the Centers for Disease Control and Prevention
Dengue - With more than one-third of the world’s population living in areas at risk for infection, dengue virus is a leading cause of illness and death in the tropics and subtropics. As many as 400 million people are infected yearly. Dengue is caused by any one of four related viruses transmitted by mosquitoes. There are not yet any vaccines to prevent infection with dengue virus and the most effective protective measures are those that avoid mosquito bites. When infected, early recognition and prompt supportive treatment can substantially lower the risk of medical complications and death. Dengue has emerged as a worldwide problem only since the 1950s. Although dengue rarely occurs in the continental United States, it is endemic in Puerto Rico and in many popular tourist destinations in Latin America.
Chikungunya - chikungunya (pronunciation: \chik-en-gun-ye) virus is transmitted to people by mosquitoes. The most common symptoms of chikungunya virus infection are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Outbreaks have occurred in countries in Africa, Asia, Europe, and the Indian and Pacific Oceans. In late 2013, chikungunya virus was found for the first time in the Americas.
Zika - Local mosquito transmission of Zika virus infection (Zika) has been reported in Mexico. Local mosquito transmission means that mosquitoes in the area are infected with Zika virus and are spreading it to people. The mosquitoes that spread Zika usually do not live at elevations above 6,500 feet (2,000 meters) because of environmental conditions. Travelers whose itineraries are limited to areas above this elevation are at minimal risk of getting Zika from a mosquito. The following map shows areas of Mexico above and below 6,500 feet.
The device, known as an ovillanta (loosely translated, it’s Spanish for “tire for laying eggs”), to destroy the larvae of the Aedes, a genus of mosquito that carries the now-notorious Zika virus as well as the dengue, chikungunya and yellow fever viruses.
For starters, the devices eliminate the need to use pesticides that can damage the environment and carry the risk of collateral damage to other insects - including those that eat mosquitoes.
The system includes an innovative designed trap created from two 50 cm sections of an old car tire, fashioned into a mouth-like shape, with a fluid release valve at the bottom.
Inside the lower tire cavity, a milk-based, non-toxic solution developed at Sudbury's Laurentian University lures mosquitoes. Inserted to float in the artificial pond is a wooden or paper strip on which the female insect lays her eggs. The strip is removed twice weekly, analyzed for monitoring purposes, and the eggs destroyed using fire or ethanol.
The solution, which now includes mosquito pheromone (the female insect's chemical perfume that helps others identify a safe breeding site), is then drained, filtered, and recycled back into the tire. The pheromone concentrates over time, making the ovillanta even more attractive for mosquitoes.
