Abstract

SANTADINO, Marina V.; RIQUELME VIRGALA, María B.  and  COVIELLA, Carlos E.. First record of native predators on the invasive species Thaumastocoris peregrinus (Hemiptera:Thaumastocoridae) in Eucalyptus in Argentina. Rev. Soc. Entomol. Argent. [online]. 2013, vol.72, n.3-4, pp.219-222. ISSN 0373-5680.

Two native predators have been repeatedly observed consuming the bronze bug, Thaumastocoris peregrinus Carpintero & Dellapé (Hemiptera: Thaumastocoridae). To identify these predators and to corroborate whether these species can use T. peregrinus as a suitable food item, egg samples of both predator species were collected from the arboretum at the Universidad Nacional de Luján. Nymphs were reared individually under laboratory conditions and fed ad libitum with nymphs and adults of T. peregrinus. The number of prey consumed daily and the development time were recorded. The predator species were identified as Atrachelus cinereus Fabricius (Hemiptera: Reduviidae) and Podisus australis Berg (Hemiptera: Pentatomidae). This research presents the first report of native predators using this invasive species as a food resource in Eucalyptus camaldulensis forest in Buenos Aires province, Argentina.
