Abstract : Samples of C. perturbans obtained by extracting cattail plants from an abandoned phosphate pit in Mulberry, Florida revealed that winter dormancy occurs in both the third and fourth larval instars. The mean number of larvae extracted per cattail was approximately four times greater in the winter than in the summer, presumed to be due to a firmer attachment of the older larvae in colder weather. Larval densities near to and far from shore did not differ at the site in Mulberry. Pyramidal emergence traps placed over the floating mat of aquatic vegetation provided an effective means of estimating the time of occurrence and density of emerging adult C. perturbans. Both the larval sampling procedure and emergence traps are techniques by which mosquito control workers can monitor populations of this species to determine when and where to apply control measures.
