COSTA, Juan F.; YABAR, Erick  and  GIANOLI, Ernesto. PARASITISM ON Eurysacca melanocampta Meyrick (LEPIDOPTERA: GELECHIIDAE) IN TWO LOCALITIES AT CUSCO, PERÚ. Rev. Fac. Nac. Agron. Medellín [online]. 2009, vol.62, n.1, pp.4807-4813. ISSN 0304-2847.

Quinoa crop (Chenopodium quinoa) is an important economic activity at Cusco. The quinoa moth: Eurysacca melanocampta (Lepidoptera: Gelechiidae) is the main insect pest recorded from Cusco in quinoa fields and it has a complex of natural enemies. This research reports parasitoid insects and percentage of parasitized larvae of quinoa moth from two localities of Cusco: Izcuchaca (3400 masl) and Quiquijana (3100 masl). Collected larvae were reared at room conditions up to emergence of adult parasitoids. Phytomyptera sp (Diptera: Tachinidae) was the main parasitoid with 19,8% of parasitized larvae from both localities. Braconidae (Hymenoptera), including Apanteles sp y Earinus sp, accounted for 27,8% and Diadegma spp (Hymenoptera: Ichneumonidae) the 5,6%. Braconidae showed a greater percentage of parasitism at Quiquijana than Izcuchaca. We discuss if diversity of associated plants, both cultivated and wild plants, influence parasitoid populations.
