WITECK NETO, Leopoldo; LINK, Dionísio  and  PASINI, Mauricio Paulo Batistella. Bioecology of Oncideres cervina (Coleoptera: Cerambycidae) in Canela Guaicá (Ocotea puberula: Lauraceae) in the central region of Rio Grande do Sul State, Brazil. Ciênc. Florest. [online]. 2015, vol.25, n.2, pp.469-476. ISSN 0103-9954.

The insect fauna knowledge of forest ecosystems have their importance in relation to damage caused by their different segments. The bioecology of the Oncideres cervina (Coleoptera: Cerambycidae) in Ocotea puberula (Lauraceae) was studied in the central region of Rio Grande do Sul state, Brazil. In 49 cut twigs were analyzed the cutoff frequency, the diameter of cut twigs and sections, twig length, posture incisions frequency, adult emergence, exit orifice size, length and volume of the larvae gallery of this species. The cut twigs period extends from February to March and this species is fit as thick cutter twigs. The incisions posture number is variable, but the highest concentration is found on sections 20 to 40 cm from the cut, with an average value of 11 incisions. Two hundred adults emerged from 27 twigs, with the most emergent on the first half of December. In order to complete its development, this species requires less wood volume if compared to other twig girdlers species.

Keywords : adult emergence; diameter cut twigs; oviposition incisions; twig girdlers.
