:: Comparison with Ovitrap::

The egg-standing trap is a method more sensitive than the larval research's one, detecting the presence of Aedes's population in low densities where could be more difficult and burdensome with the larvae collection's method. This method is efficient and that's a low cost method, but it demands workers in lab for counting the number of eggs put in the slats (egg-standing substract) and for identifying the species of Aedes which were collected. The traps' positivity, determined by the egg-standings done in the slats, provides information on the infested areas in a certain local. Besides, it permits the staff to infer about the abundance of females. However, the confiability of those indexes still being very questioned. The biggest difficult of interpretating the field's results, with the Ovitrap using, is in the fact of this trap does not allow to quantify the number of females that visited the trap or the number of eggs deposited by each female. Therefore, the lack of these values infers, in a direct way, in the conclusions about the vectorial population's size, in a determined area.
