Abstract During the samplings described here, Aphidius avenae (=picipes) (Haliday, 1834) was collected. This species has been reported in Chile but has never been studied in terms of its relative abundance and prevalence in central and southern Chile by using classical or molecular methods. The composition of the parasitoid assemblages on several cereal aphid hosts was examined for three seasons in agricultural landscapes. In this note, we describe the prevalence of this parasitoid species in cereal aphids and other aphid hosts and discuss the abundance of this parasitoid compared to other aphid parasitoids and the probable origins of this important aphid parasitoid species in Chile. The results indicate that A. avenae has a low prevalence compared to...
