Mosquito Larvae in Axils of the Imported Bromeliad Billbergia Pyramidalis in Southern Florida
Abstract
At monthly intervals for a year, in Daytona, Tampa, Vero Beach and Miami, a survey was conducted of the aquatic stages of mosquitoes existing in water impounded by the leaves of the imported bromeliad Billbergia pyramidalis. A few Aedes aegypti, Culex quinquefasciatus, Toxorhynchites rutilus and Corethrella appendiculata were found, but almost all of the mosquitoes belonged to the genus Wyeomyia, Wyeomyia vanduzeei was predominant at 3 of 5 sites in Miami, but at all the other sites W. mitchellii was predominant. Average annual production of Wyeomyia per bromeliad was estimated as 107 adults based upon the number of pupae collected. Pupae were found throughout the year. There was a linear relationship of numbers of pupae to numbers of eggs + larvae collected at lower densities of eggs + larvae.Downloads
