Introduction
The citrus whitefly, Dialeurodes citri (Ashmead), was once the most important citrus pest in Florida, but today it ranks below the purple scale Florida red scale, rust mite, and possibly others. It is nevertheless a serious pest in florida. A native of India, it appears to have been introduced into Florida some time between 1858 and 1885 (Morrill and Back, 1911). It is now found out-of-doors throughout Florida and parts of other Gulf States and California2 and in greenhouses in many parts of the United States.
