Research Reports: Predator-Prey Interactions Between Typhlodromalus Peregrinus and Polyphagotarsonemus Latus: Effects of Alternative Prey and Other Food Resources

Jorge E. Pena


Studies on predation and feeding habits of Typhlodromalus peregrinus (Muma) were conducted in the laboratory and greenhouse. Throughout the study, the broad mite, Polyphagotarsonemus latus (Banks), the citrus rust mite, Phyllocoptruta oleivora (Ashmead), commercial bee pollen and pollen from Schinus terebinthifolius, Parthenium hysterophorus and Bidens bipinata were used as predator food. Typhlodromalus peregrinus consumed P. latus eggs, immatures and adults. T. peregrinus consumed 23-75% of the prey population in 6 days. T. peregrinus did not reject P. oleivora as prey, but favored P. latus when the latter was present. T. peregrinus developed on bee pollen, bee pollen and P. latus, and on S. terebinthifolius pollen.
