Aedes aegypti L. (Diptera: Culicidae) is a mosquito broadlyfound in tropical and temperate areas of the world. It is the main vector ofdengue, chikungunya, zika and yellow fever (urban cycle), among other viruses. Aedesaegypti immatures develop in water holding containers, and frequently useartificial containers in urban settings as larval habitat. Ovitraps areartificial oviposition sites, a tool developed for mosquito populationsurveillance and to assess effectiveness of control measures. The preferencefor different oviposition substrate materials was assessed in the field, in twolocalities of Salta province, northern Argentina, where dengue outbreaks arefrequent. The proportion of positive traps did not differ between ovipositionsubstrates. However, higher numbers of eggs were laid in cotton fabric andvelour paper, which were better than wooden paddle and blotting paper if theaim was to maximize the numbers of eggs collected. The results also evidencedthat substrate preference for oviposition did not differ between geographicregions.
