(Damage characterization and control tactics to broad mite (Polyphagotarsonemus latus Banks) in Paraguaytea plants (Ilex paraguariensis A.St.-Hil.)). The broad mite (Polyphagotarsonemus latus) is referred as one Paraguay-tea (Ilex paraguariensis) pest, an important culture in the south of Brazil, and not existing studies about its control in the Paraguay-tea culture, the present work aimed to characterize the damages and to evaluate control tactics of this pest of Paraguay-tea seedlings, in green house. In the experiment 1, the Paraguay-tea seedlings were divided in two groups of 50 seedlings, divided in 5 repetitions. In one of the groups the seedlings were artificially infested with mites grown in laboratory. Weekly, during 3 months, the plants were appraised, the alterations possibly related to the mites presence were observed. In the second experiment, an identical group of seedlings was infested by the broad mite and 15 days after the following treatments were applied: a) mitecide based on cyhexathin, b) Hirsutella thompsonii fungus isolated CG 541 (1×106 conídios/mL), c) distilled water and d) without infestation, considered control treatment. The evaluations accomplished were before and at the end of the experiment, consisting in counting the mites in 10 leaves/repetition, determination of the height and number of leaves/plantings and dry weight of all the plants (end). The mites concentrated on the abaxial surface of the apical and younger leaves, which presented the screw borders, abnormal ribs development, rough surface and tan. Early leaves fall was also observed. There was no difference in the size of the plants and leaves number, but a 30% biomass reduction in the fungus treatment plants and in those without treatment has happened. The broad mite caused damages to the seedlings in nurseries and the mitecide control reduced the population of the same and the damages.
