Recycled tire traps are seven times more effective than traditional mosquito traps

Comments Off on Recycled tire traps are seven times more effective than traditional mosquito traps

The use of recycled materials  is not only good for the environment . Sometimes, it is simply the best way to get a job done. Such is the case with the ovillanta mosquito traps crafted from old tires and tested in Guatemala. Over the course of ten months, researchers supported by the Guatemala Ministry of Health’s Vector Control Program observed the number of mosquito eggs collected by the simple traps. Based on their pending study, the ovillanta tire traps captured seven times the number of eggs as a standard trap. The ovillanta traps are specifically deployed to capture mosquitoes of the  Aedes genus. These mosquitoes are those notoriously known for transmitting devastating viruses, such as Zika, dengue, chikungunya, and yellow fever.  Aedes mosquitos can become resistant to pesticides and although adults only live for about two to four weeks, eggs can remain viable for up to a year. This enables populations to mitigate the effects of hazardous weather. Many communities lack the resources to deal with this resilient pest and are particularly vulnerable to outbreaks of mosquito-borne diseases.

The mosquitoes are lured into the tire’s basin with a non-toxic substance that includes a special mosquito pheromone, which signals to pregnant mosquitoes that this is a safe place to lay their eggs. The eggs are then dropped on a small “raft” floating in the solution, which is removed twice a week so that the eggs may be removed and destroyed. This low-tech solution costs only a fraction of traditional techniques and does not harm other animals in the process of catching the mosquitos.

Comments Off on Bernie Sanders is now calling for a nationwide ban on fracking

Perhaps more than ever before, the environment is a big issue in this year’s presidential campaign race. Bernie Sanders has solidified his stance against fracking in recent speeches, calling for a nationwide ban on shale gas extraction . The controversial practice is highly criticized by environmentalists and public health advocates due to its use of harmful chemicals that can leach into drinking water supplies and negatively impact delicate ecosystems. Fracking activity has also been linked with an increase in seismic activity in recent years, posing an even bigger threat to wildlife and human communities.
