Description:
<p>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. /// Se realizaron estudios de los habitos alimenticios y predacion de Typhlodromalus peregrinus (Muma) en el laboratorio y en el invernadero. Se suministro como alimentos el acaro blanco Polyphagotarsonemus latus Banks, el acaro tostador de los citricos Phyllocoptruta oleivora (Ashmead), pollen de abejas, pollen de Schinus terebinthifolius, de Parthenium hysterophorus, y de Bidens bipinata. El acaro predador T. peregrinus consumio huevos, estados larvarios, y adultos de P. latus. T. peregrinus consumio el 23-75% de la presa en 6 dias. T. peregrinus prefirio P. latus como presa y no rechazo P. oleivora como presa, pero cuando P. latus se encontro presente prefirio a este ultimo. T. peregrinus se desarrollo en pollen de abejas, en una mezcla de pollen de abejas y P. latus, y en pollen de Schinus terebinthifolius.</p>
