SAN FERNANDO CITY – To reduce dengue incidence in public schools, the Department of Science and Technology (DOST) in Ilocos and the Department of Education (DepEd) partnered in distributing Ovicidal Larvicidal (OL) Trap kits in selected schools in the region.
Edwin M. Dilim, project assistant, said OL trap is a device composed of a strip of lawanit board immersed in an ordinary tin can (regular-sized evaporated milk) painted black with larvicide solution.
The trap works once the solution moistens the lawanit which then becomes highly attractive for female mosquitoes to lay eggs on.
“Mosquito eggs exposed in the solution die thus mosquito population is reduced,” Dilim said.
The system, developed by DOST’s Industrial Technology Development Institute (ITDI) in cooperation with the DOST-Philippine Council for Health Research, is highly designed to attract the Aedes egypti mosquitoes, the carrier of the dengue virus.
In Region one, the DOST and DepEd have already distributed a total of 2,985 OL trap kits to 2,387 and 508 elementary and secondary public schools, respectively.
Kits distributed are as follows: La Union, 418; Pangasinan, 1,482; Ilocos Sur, 558; and Ilocos Norte, 437.
“Each classroom gets two kits and a supply of the solution good for three months,” said Dilim.
Distribution started in September 2013 and finished in March 2014.
The DOST now maintains the Nationwide Dengue Vector Surveillance Website where efficiency of the kits is monitored through reports via text messages.
“Science teachers, clinic teachers or school nurses are in-charge of monitoring and reporting the number of OL Kits with positive and negative presence of mosquito eggs,” Dilim said.
Reports are reflected in the website. Once the school registered high incidents of positive mosquito eggs, necessary actions will be taken immediately.
Dilim hopes the public to see that there is a technology that works in the reduction of dengue vector.
“This local technology indeed is proven effective and we hope that with accurate monitoring, the fatal dengue disease which usually strikes children will be prevented,” Dilim said. (MCA/JNP/PIA-1 La Union)
