Abstract

DIAZ-RAMOS, Sara Gabriela et al. Dynamic population of Pityophthorus Eichhoff (Curculionidae: Scolytinae) caught by traps baited with pheromones in the forest La Primavera, Jalisco. Acta Zool. Mex [online]. 2016, vol.32, n.3, pp.296-299. ISSN 2448-8445.

Monitoring of Scolytidae was carried out with 10 Lindgren traps of eight units baited with frontalin and kairomone + (alpha-pinene), from 2010-2012, with five traps in pine plantations and five traps in natural oak-pine forest at La Primavera forest. Insects attracted to the traps were Pityophthorus species. Seven species were identified, of which Pityophthorus obtusipennis Blandford, P. occlusus Bright and P. segnis subopacus Blackman, are new records for Jalisco, with low densities. The most abundant species were P. cacuminatus Blandford with 719 specimens, with flight periods in the low rainfall season, P. exquisitus (Blackman) not associated with pines, with 105 individuals, with similar trend to P. cacuminatus, and P. schwerdtfegeri Schedl myelophagous species with 22 individuals, captured in periods of rainfall from 50 to 10mm.

Keywords : Scolytinae; rainfall; Pityophthorus cacuminatus.
