Resumen

ZAVIEZO, Tania; ROMERO, Alda; CASTRO, David  y  WAGNER, Adrián. First record of Goniozus legneri (Hymenoptera: Bethylidae) in Chile. Cienc. Inv. Agr. [online]. 2007, vol.34, n.1, pp.57-61. ISSN 0718-1620.  http://dx.doi.org/10.4067/S0718-16202007000100007.

Codling (Cydiapomonella) and carob moths (Ectomyelois ceratoniae) are important pests of apples and walnuts in Chile. During fruit samplings, a parasitoid was found attacking the larvae of these species. Because there was no previous information on larval parasitoids of them in Chile, a study was conducted with the objectives of identifying the parasitoid species found, to gain information on its biology and to determine how widespread it was in central Chile. Fruits from apple and walnut trees were sampled in different localities of central Chile, from the Metropolitan to the VII Region. The species found in the fruits attacking the larvae of the codling and carob moths was Goniozus legneri. The mean parasitism observed in laboratory conditions was 50 and 33% in C. pomonella and E. ceratoniae, respectively. The number of eggs laid per host in C. pomonella was 10.8 ± 3.8 and in E. ceratoniae was 8.3 ± 3.8. This is the first report of this parasitoid species in Chile
