DOST IX will send 42,068 OL traps to public schools


The Department of Science and Technology IX (DOST) Information Officer Thelma Diego has revealed that they’ll send 42,068 Ovicidal/Larvicidal (OL) traps in public schools in Region IX by July to help prevent dengue fever cases in this region.

Public elementary and high schools will be receiving two OL traps for each classrooms, one for indoor and one outdoor.

These 42,068 OL traps will cover 2,035 DepEd schools for elementary and 369 DepEd schools for secondary.

The traps will be installed in 16,177 instructional classrooms for elementary level and 4,857 instructional classrooms in secondary.

According to Diego, DOST Secretary Mario Montejo instructed that all public schools elementary and secondary will be given the traps because of dengue incidents are all over the region.

The DOST’s Industrial Technology Development Institute (ITDI) is set to deliver these traps directly to these public schools.

She said that a science teacher or school nurse will be trained on how to use and monitor the traps and will be the dengue coordinator.

The OL traps according to Diego, has these larvicide which can help kill mosquito eggs deposited in OL trap. “The mosquito will lay eggs, there is a larvicide, the eggs deposited inside OL trap will be killed, not 100% but more or less  85% of the larvae will be killed inside the OL trap this will lessen mosquito population, and these eggs will not hatch to become an adult mosquito.”

Aside from this, the office will also have this website for OL trap monitoring surveillance where the website will be able to determine OL trap results. This will also be included in the teachers training. 

The teacher in-charge will also send result of the OL traps to the OL trap surveillance data through text which will directly be uploaded to the DOST OL trap surveillance website. 

She said that the OL trap is just one of the tools to fight dengue this is also a tool used for surveillance of the mosquito population.

In Region IX, there are 3,237 cases of dengue fever from January to June 20, 2013 with 31 deaths while for Zamboanga, from January to present, 1,800 with 18 mortalities.

The OL Trap is the invention of DOST’s Industrial Technology Development Institute (ITDI). The OL Trap includes three components: a black cup, a fiberboard and organic pellets.

The trap easy to use because the user only needs to fill the cup with water, pour a sachet of organic pellet and place the stick, which is made of fiberboard into the solution with the rough surface facing up.

The cup is placed inside or outside the school in a low-lying area and let it stand for up to six to seven days. After seven days, gently brush off into the solution the mosquito eggs stuck on the stick by using used toothbrush. Then disposed all the liquid content of the cup on dry ground and repeat the same procedure.

The scent of the organic pellets solution invites female mosquitoes to the OL Trap where they lay eggs on the lawanit stick and on the solution itself.

The eggs and the wrigglers die once it get expose to the solution; thereby, preventing the next generation of mosquitoes from reaching adulthood.
