Problem addressed
The OL trap was launched in 2011 to address the burgeoning problem of dengue infection. The DOST-ITDI OL trap research team designed the trap to detect, monitor, and control the population of the dengue-carrying Aedes aegypti mosquitoes. The trap works by attracting female mosquitoes to lay eggs on the paddle drenched with an organic solution. This solution kills the eggs and larvae, preventing mosquitoes from reaching adulthood.
The OL trap’s major accomplishment is that it “significantly reduced mosquito densities and dengue virus transmission in various schools and communities nationwide”
The Mosquito OL-Trap has three important parts: a black container, a small strip of lawanit measuring 1″ X 6.5″ (like an ice drop stick) for mosquitoes to lay their eggs on, and a larvicide solution to kill the mosquito larvae that will hatch in the strip of wood and in the solution.
Advantages
The solution is potent against mosquitoes but safe for humans and animals, as it is composed of ingredients commonly used in the kitchen for food preparation.
Brief Description/ Features of the Technology
The scent of the solution invites female mosquitoes to the trap where they lay eggs on the stick and on the solution itself. The stick, moistened by the solution through capillary action, is highly attractive for mosquitoes to lay eggs on. As the eggs and the hatched larvae (also called “wrigglers”) get exposed to the solution, they die. The trap does not kill the adult mosquitoes. Instead, its ovicidal and larvicidal effect prevent the next generation of mosquitoes from reaching adulthood, thus curbing the Aedes mosquitoes population.

Market Potential/ application
Now commercially available, the OL trap is able to contribute to the government income. Other countries with high dengue incidence have also expressed interest in the technology.
