Five factors associated with natural oviposition sites were tested for their attractancy to ovipositing Aedes triseriatus, including dyed oviposition water, presence of decaying organic matter, a dark oviposition container, water in which conspecific larvae have been reared to the 4th instar and the presence of eggs on the balsa wood oviposition substrate. A replicated fractional factorial design was used to examine the effects of the above factors on oviposition behavior in laboratory experiments. Regression analysis showed dyed oviposition water and eggs on the oviposition substrate to be statistically significant attractants for ovipositing A. triseriatus females. The attraction to dyed oviposition water indicated that dyed water in oviposition traps may greatly increase their competiveness with naturally occurring oviposition sites.
