Attractive activity of plant extracts for the oviposition of Aedes aegypti L. (Diptera: Culicidae)

ABSTRACT Aedes aegypti is one of the most important culicidae species for public health, since it transmits the viruses for yellow fever, dengue fever, chikungunya and zika. With the purpose of analyzing the effect of plant extracts on the oviposition of this vector in ovitraps, 100 ovitraps were se...

With the purpose of analyzing the effect of plant extracts on the oviposition of this vector in ovitraps, 100 ovitraps were set containing an attractive plant substrate and a pressed wooden palette vertically installed on the pot for female oviposition.
