中文摘要

Aedes aegypti L. is the primary dengue vector in southern Taiwan. This article is the Trst
report on a large-scale surveillance program to study the spatial-temporal distribution of the local Ae. aegytpi population using ovitraps stratiTed according to the human population in high dengue-risk areas. The sampling program was conducted for 1 yr and was based on weekly collections of eggs and adults in Kaohsiung City. In total, 10,380 ovitraps were placed in 5,190 households. Paired ovitraps, one indoors and one outdoors were used per 400 people. Three treatments in these ovitraps (paddleshaped wooden sticks, sticky plastic, or both) were assigned by stratiTed random sampling to two areas (i.e., metropolitan or rural, respectively).Wefound that the sticky plastic alone had a higher sensitivity for detecting the occurrence of indigenous dengue cases than other treatments with time lags of up to 14 wk. The wooden paddle alone detected the oviposition of Ae. aegypti throughout the year in this study area. Furthermore, signiTcantly more Ae. aegypti females were collected indoors than outdoors. Therefore, our survey identiTed the whole year oviposition activity, spatial-temporal distribution of the local Ae. aegypti population and a 14wk lag correlation with dengue incidence to plan an effectively
proactive control.
