Technical Abstract: Ficus Whitefly (Singhiella simplex) was first reported in Miami-Dade County in August 2007. This invasive pest causes infested plants to exhibit leaf yellowing, followed by leaf drop. The pest has been recorded on multiple ficus hosts including Ficus benjamina, F. altissima, F. bengalensis, F. microcarpa, F. aurea, F. lyrata, and F. macllandii. Little information is known about ficus whitefly’s reproduction and development or its potential to be controlled by natural enemies currently present in Florida. We report on reproductive parameters measured under four different temperature regimes (15°C, 25°C, 27°C, and 30°C). In addition, predation rates of the predator Delphastus catalinae are presented for three life stages of ficus whitefly eggs, small nymphs (2nd-3rd instars), and large nymphs (4th instar-pupae). Results from these studies will be used to develop future management strategies.
