Troncones Mosquito Control Project needs funding!
Villagers working to reduce mosquito-borne dengue, Zika virus and chikungunya.
We live between Troncones and Majahua, two small villages on the southwest coast of Mexico. Over the last year more than 80% of the people living in these villages contracted either dengue or chikungunya, a dengue-like illness. Both of these are transmitted by the Aedes spp. mosquito, which can also carry the Zika virus.
A Canadian researcher at the Laurentian University, Dr. Gerard Ulibarri, designed a mosquito trap called an “ovillanta.” It consists of two sections of an old car tire, one facing up and the other facing down, plus a small piece of PVC pipe and a valve. The lower section of tire holds water infused with a non-toxic milk based solution (that attracts female Aedes spp. mosquitos) and a strip of paper on which the female lays her eggs.
The fluid is drained from the lower tire via the pipe, filtered to remove any larvae, and returned to the tire, twice a week. The paper strips can stay as long as they remain clean, otherwise they are removed and the eggs are destroyed with fire.
A 10-month test study was done in Guatemala. The “ovillanta” trap proved to attract seven times more mosquitos than standard traps. They are a low-cost, environmentally safe method of seriously reducing the numbers of this type of mosquito that can carry and transmit three very unpleasant and potentially fatal illnesses, including the Zika virus that is garnering press around the world. And it does all this without the use of chemicals.
The “ovillanta” system is estimated to cost only a fraction of what it costs to target adult insects with pesticides. Still the cost of the traps, while relatively inexpensive to Americans or Canadians, is equivalent to at least one, two, or three day’s wages to the people in these villages. In addition, the liquid attractant and paper for the eggs must be replaced regularly.
Rainy season is almost upon this area and we are helping the villagers to implement an abatement program to significantly reduce the population of Aedes spp. mosquitos.
The plan is to document the program, record results, prove what can be done with sufficient effort and organization, and share what we learn with other villages.
The program for the first year will cost approximately $22,500 USD. This is the set-up year; following years should be somewhat less expensive.
Please help us to help these villages reduce the risk of contracting dengue, the Zika virus and chikungunya.
