To understand the effects of fish predator’s kairomones on Aedes mosquitoes’
oviposition, we established an experiment using gravid Aedes females. Kairomones
concentrations were established using Hampala macrolepidota. One individual fish was
placed inside containers with varying water levels (1 L, 5 L, and 10 L of water). The fish
were kept in the containers for 24 hours and were removed immediately at the start of
each trial in order to have the kairomones remnants. Twenty gravid adult females of
Aedes aegypti and Aedes albopictus were allowed to lay eggs on oviposition site with
various treatments: (1) control without any kairomones; (2) kairomone remnant in 1 L of
water; (3) kairomone remnant in 5 L of water; and (4) kairomone remnant in 10 L of water.
There are significant differences between the numbers of eggs laid by both Aedes species
for each different treatment (F = 9.131, df = 16, p
