摘要: Population dynamics of the immature stages Aedes aegypti (Diptera: Culicidae), vector dengue: a longitudinal study (1996-2000). A four year was conducted on natural population imma- ture after re-invasion Argentina by this in 1987. Thirty six plastic containers with 700 ml dechlorinated water were placed La Plata Zoological Garden, Plata, Argentina. strip filter paper around each container added to facilitate egg counting.
