DAPOTO, Graciela; GIGANTI, Humberto; BONDONI, Mariano  and  OLAVE, Anabel. First record of Hypercompe indecisa (Lepidoptera: Noctuidae: Arctiinae) on pear trees and poplars in Patagonia. Rev. Soc. Entomol. Argent. [online]. 2010, vol.69, n.1-2, pp.137-139. ISSN 1851-7471.

The Alto Valle of Río Negro and Neuquén is the main production zone of pomme fruits from Argentina. The main pest is Cydia pomonella L. (Lepidoptera: Tortricidae). Changes operated in control strategies in the last years have brought changes in the biodiversity of fruit orchards. During the season  2008/09, Hypercompe indecisa (Walker) (Lepidoptera: Noctuidae) was detected in a fruit establishment of Vista Alegre (Neuquén) under organic production causing  serious damages on fruits and leaves of pear trees and in the leaves of Populus spp. Hypercompe  indecisa is reported for the first time in Patagonia  and  is the first record of this species on Populus spp.and Pyrus communis L.

Keywords : Hypercompe indecisa; Sexual Mating  Disruption; Fruit growing; Patagonia.
