Abstract
The search for information about the species of cerambycids associated to Ocotea puberula (Rich.) Nees (Lauraceae) on twigs cut off by Oncideres cervina Thomson, 1868 (Cerambycidae: Coleoptera), motivated the present research. It was determined in the central region of Rio Grande do Sul State the emergence of cerambycids with biweekly evaluations in 49 twigs cut off. In addition to O. cervina , the twig-girdler, it was observed three other species of cerambycids, Trestonia capreola (Germar, 1824), Dihammaphora signaticollis Chevrolat, 1859 and Tropidozineus rotundicollis (Bates, 1863) (Cerambycidae: Coleoptera). It was the first record of host plant in this family botany for T capreola and D. signaticollis . The emergence period of cerambycids from twigs of O. puberula goes from September to December, with population peaking in November.
