abstract
The citrus rust mite (CRM), Phyllocoptruta oleivora (Ashmead) (Acari: Eriophyidae), infests plants of genera Citrus and Fortunella (family Rutaceae). CRM infests leaves, branches and fruits causing fruit rind russeting resulting in loss in yield and fruit quality making them unfit for export. The damaged fruits have surface bronzing (damage), peel shrinkage, lower juice volume, higher soluble solids, higher acids and higher concentrations of acetaldehyde and ethanol than normal fruits. CRM injury to the leaves is also one of the predisposing factor for the development of greasy spot, a disease caused by the fungus, Mycosphaerella citri Whiteside. CRM infestation may lead to 40% fruit yield loss and nearly 25% reduction in fruit volume. These microscopic organisms have very short life cycle of 7 to 10 days with many overlapping generations per year and with maximum infestation found during late June to August months. In the present paper the nature of damage, biology and ecology of the pest were clearly reviewed. Monitoring methods and other components of integrated management methods viz., cultural, chemical, IGR's, botanicals and biological control were also been reviewed in detail. However, regular monitoring and resistance management were emphasized as the prime important aspects for programming a sound integrated pest management programme as a future perspective in this present review.
