TURIENZO, Paola. First record in Argentina of a plant-insect association, with interest in biological control. Ecol. austral [online]. 2006, vol.16, n.1, pp.95-98. ISSN 1667-782X.

The species Chrysolina quadrigemina (Suffrian) (Coleoptera: Chrysomelidae) is recorded for the first time in Argentina, this being also the first record of this genus in the country. Its host plant, Hypericum perforatum L. (Clusiaceae) is native from Asia, Europe and Africa, and has behaved as a strong invader in several countries of the world where the implementation of a biological control program was necessary. The only country in South America that implemented such a control was Chile, in 1953. The arrival of C. quadrigemina to southern Argentina is probably due to natural dispersion from Chile. This record increases the number of Chrysomelidae species in the country.

Keywords : Coleoptera; Chrysomelidae; Chrysolina; Hypericum.
