Integrated pest management in Florida citrus.
The author discusses integrated pest management (IPM) programmes for citrus in Florida. Although formal IPM programmes began in the mid-1970s, classic IPM principles have been studied and implemented since the early 1900s. The current programme utilises selective chemicals, natural enemies and cultural practices to maintain pest populations below economic levels. The historical evolution and current status of this programme are discussed. Phyllocoptruta oleivora (Ashm.) is considered to be the most important arthropod pest, followed by Unaspis citri (Comst.), Planococcus citri (Risso), Dialeurodes citri (Ashm.), D. citrifolii (Morg.), Panonychus citri (McG.) and Eutetranychus banksi (McG.) in that order.
