ORTEGO, Jaime  y  MIER DURANTE, M. Pilar. First record of Essigella californica (Essig, 1909) (Hemiptera:Aphididae) in Argentina. Rev. Fac. Cienc. Agrar., Univ. Nac. Cuyo [online]. 2012, vol.44, n.1, pp.199-204. ISSN 1853-8665.

Aphids were sampled on several Pinus species in some localities of Argentina. Essigella californica was caught for the first time in Argentina, in five provinces. Aspects of its biology and distribution are presented. Biological and morphologic aspects that allow to separate three genera of the tribe Eulachnini (subfamily Lachninae) present now in Argentina: Cinara, Eulachnus and Essigella) are provided.

Palabras clave : Aphids; Pinus; Essigella californica; Argentina; Pest.
