 ABSTRACT

The studies were conducted to develop a module for mass production of phytoseiid predators using data of four batches of mass production of phytoseiid on French bean plants grown in polycarbonate house during different months. Regression analysis of the pooled data from four batches of mass production of the predator showed that the predator population reached peak around 23 days after predator release atfour predators per leaflet of French bean plants ten days after infestation of spider mite, Tetranychus urticae at ten per leaflet. This model can be used to predict the day of peak predator population making use of the population counts of different stages of both prey and predator on any given day, and accordingly plan the harvesting of predators efficiently.
