Abstract

Adult gravid female Aedes aegypti L. tends to lay few eggs in several water-filled containers instead of laying in few locations, a behavior called 'skip oviposition'. This behavior could be counteracted since gravid female was found highly attracted to oviposit in organic leaf infusions of fermenting leaves in water, like the bamboo leaf infusion. A New Leaf Infusion (NLI, identity will be revealed pending patent application) was found more attractive as oviposition attractant to gravid female dengue mosquito in the laboratory than the usual bamboo leaf infusion (BLI). Under caged conditions, about 54% of the eggs were laid in powdered NLI, 34% in fermented NLI, 11% in BLI and 1% in water alone. Under field conditions at LSPU, San Pablo City (SPC), 74% of eggs were laid in NLI, 23% in BLI and 3% in water. Further verification of the attractancy of the ovitrap in 20 classrooms at LSPU, SPC showed that 93% of the eggs were laid in NLI and only 7% in water. The NLI have great potential in attracting A. aegypti to lay majority of her eggs, while the release of hungry water bug (voracious wriggler feeder) consumed almost all the developing wrigglers that hatched from the eggs in the ovitrap. This 'attract and kill' technology could be a novel approach in the sustainable management of A. aegypti.
