To protect plants from damage caused by Panonychus citri (McGregor), practical methods for the use banker plants have been developed to provide a habitat and augment natural enemies of several agricultural pests. The average population density of predatory mites on an Oxalis corniculata (creeping sorrel) sod culture was significantly higher (three times) than that on normal sod culture. Furthemore, the average population density of spider mites on creeping sorrel sod culture was significantly lower (3.7 times) than when weed control was practiced. Average consumption of the eggs and females of Tetranychina harti (Ewing) by Neoseiulus californicus (McGregor) females was approximately 1.96 eggs and 1.93 females per day, respectively. Phytoseiulus persimilis Athias- Henriot females never consumed T. harti. However, total development time of T. harti from egg to adult on O. corniculata was 17.4 days, and hatchability and survival rate were 77.5% and 84.8%, respectively.
