The Citrus Red Mite (Panonychus citri): A Pest of Citrus Crops
Emilie Demard and Jawwad A. Qureshi
Panonychus citri is a phytophagous mite of economic importance in open citrus orchards and a major pest in Citrus Under Protective Screen (CUPS), a new undercover production system tested in Florida. Immatures and adults feed on citrus leaves, fruits, and green twigs resulting in mesophyll collapse, shoot dieback, and fruit drop. In Florida, P. citri occurs throughout the year but is most abundant in spring or early summer and autumn or early winter. Although chemical sprays like Abamectin or Fenbutatin oxide provide some control of P. citri, resistance has been reported in different regions of the world. Several predatory insects and mites have been shown to attack the mite and could be potential natural enemies to use in biological control programs.
