Overview of a classical biological control project directed against the red palm mite in Florida

Abstract

Information is provided on the steps involved in classical biological control programs, with an outline of the steps achieved in the classical biological control of the red palm mite, Raoiella indica (Acari: Tenuipalpidae), in Florida. An overview is provided of the results and an accompanying paper by Bowman and Hoy (2012) describes the molecular analyses conducted to characterize phytoseiid predators of the red palm mite collected from Mauritius. The Mauritius phytoseiids were identified as Amblyseius largoensis, using morphological criteria, and compared to four populations of A. largoensis from Florida. The difficulties encountered in the systematics, rearing, and evaluation of the Mauritius phytoseiids are described. A method was tested for obtaining DNA from single mites without destroying the body so that voucher specimens can be maintained. Ultimately, the project was terminated due to constraints expected in obtaining permission to make releases.
