title: Seasonal incidence and vertical distribution patterns of oviposition by Aedes aegypti in an urban environment in Trinidad, W. I.
abstract: The oviposition patterns of Aedes aegypti were investigated using modified ovitraps placed along 4 vertical transects and monitored weekly for 52 wk in St. Augustine, Trinidad, W.I. From the 832 ovitraps exposed at ground level, 1.2, 3.0 and 4.6-m elevations, 43% (361) were found containing 20,114 Ae. aegypti eggs. During the wet season, 52.7% of the eggs were collected whereas during the dry season only 47.3% were collected. Egg populations were highest at the 1.2-m elevation. The implications of these results are discussed.
