Abstract
Effect of crowding and mutual interference of the phytoseiid predatory mite Phytoseius plumifer (C. & F.) fed on spider mite Tetranychus urticae Koch and broad mite Polyphagotarsonemus latus (Banks) on its feeding capacity was studied in the laboratory. Increasing number of predatory mite per each arena decreased food consumption. A negative correlation was found between numbers of P. plumifer and its feeding capacity. Influence of prey species on different life-table parameters of P. plumifer revealed that feeding on broad mite prolonged generation time (T) and doubling time (DT) of the predatory mite, while feeding on T. urticae increased the net reproductive rate Ro, intrinsic rate of natural increase rm, finite rate of increase erm (λ) and gross reproduction GRR of the predatory mite P. plumifer.
