LAOAG CITY, June 21 (PIA) — The city government distributed the locally-developed mosquito ovicidal-larvicidal trap (OL trap) to barangays in the city to help address the problem of denque.
The OL Traps were handed by Mayor Michael Farinas, through the City Health and General Services offices. Around 20,000 pieces of the device were given to the barangay captains for all 80 barangays of the city according administrative officer Josefina Mata.
“There were different allocations for the barangays. It is up to the captains to distribute the device to the people in their areas,” Mata said.
Barangay San Lorenzo got the biggest allocation with 800 OL Traps, followed by barangays San Matias and Calayab with 644 and 519, respectively.
A Department of Health dengue surveillance report showed that 18 dengue cases were recorded in the city for the period of January to March this year. Moreover, in August of last year, Laoag City was placed under a state of calamity due to the spread of dengue virus.
The OL Trap was developed by the Industrial Technology Development Institute of the DOST following several laboratory tests.
Mata said the device is composed of an ordinary dark plastic container, a piece of wood or lawanit that resembles an ice cream bar stick, and 4 sachets of pellets.
Accordingly, the pellets are mixed with about 250ml of water. The stick, drenched with the solution, is placed upright in the container with one end deep in the solution to continuously sip it.
The pellets, containing an attractant, draw the Aedes aegypti mosquito to lay its eggs into the rough part of the solution-saturated strip. The solution then kills the eggs and larvae. The public may wipe away the eggs and larvae from the strip and use it again.
“If the pellets are consumed, the public can buy a sachet at the Department of Science and Technology,” Mata said.
Experiments made by the DOST showed the high efficiency of the OL Trap solution with a 70 percent attraction rate and 100 percent mortality rate.
A female mosquito can lay as many as 400 eggs four times in its life, 80 percent of which will turn out to be female. But through the OL Trap, the next generation of mosquitoes in an area will be wiped out, and the deadly dengue virus with it.
The OL Trap may last up to two months.
Aside from the OL Trap, the city government is planning to distribute the Rice Husk Mousticide, another new innovative tool for the safe and effective control of the mosquito larvae. (ANL/CPC-PIA 1 Ilocos Norte)
