The South American Fruit Fly Anastrepha fraterculus (Wiedemann, 1830) (Diptera: Tephritidae) is one of the most important pests of temperate fruits in Southern Brazil. Little information regarded to pest damage is available when this insect is associated with vineyards. In this work was evaluated the plastic cover effect on seasonal fluctuation of A. fraterculus adults in vineyards of cv. Moscato Giallo. The experiment was conducted on 2005/06 and 2006/07 seasons in a vineyard located in Flores da Cunha, RS (latitude 29° 06' South, longitude 51° 20' West and altitude 541 m), covered with an impermeable plastic cloth (2.65 m x 160 µm), in 12 rows with 35 m, with five rows left uncovered (control). Adults were monitored in two areas with McPhail traps using 5% hydrolyzed protein (BioAnastrepha®) from October to April in both seasons. No significative differences were observed in A. fraterculus catches among cover and conventional system, concluding that plastic covering does not cause influence in mobility and seasonal fluctuation of A. fraterculus in grapevine cultivation.
