Table 1.
Aggregation of resident Aedes larvae in 6 Florida cemeteries. Cemeteries were sampled once in early rainy season (1) and in the middle to late rainy season (2) of 2009. Thirty water-filled vases per cemetery were sampled (15 at Palmetto). Aggregation indices were calculated for A. albopictus and A. aegypti and modified to account for patch-size using predicted Aedes abundance (see text for details).
