Resumo: Ovitraps containing various concentrations of hay infusion and tap water were exposed weekly in the field for 15 wk to determine the oviposition patterns of Aedes aegypti. The results showed 10, 20, 60 and 80% hay infusions each attracted numbers of Ae. aegypti eggs oviposited and egg occurrences. No repellent effect was observed. In another field study, significantly more eggs and egg occurrences were collected from 25 and 50% hay infusions and tap water. The differences in these results from those of a previous study in Puerto Rico and discussed.
