The knowledge of the flow of parasitoids in cultivation areas is a practice that should be adopted forchoosing a best method for the regulation of pest populations. The aim of this study was to determine the occurrenceof parasitoids associated with larvae of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) and Dichomerisfamulata Meyrick (Lepidoptera: Gelechiidae) in maize (Zea mays L.) under organic and conventional productionsystem. The experiment was conducted at the National Research Center for Maize and Sorghum (CNPMS) in SeteLagoas, Minas Gerais State, Brazil. Hymenoptera parasitoids emerged from S. frugiperda, including the Ichneumonidae:Campoletis flavicincta, Colpotrochia sp. nov., Eiphosoma laphygmae and Ophion flavidus; the Braconidae speciesChelonus (Chelonus) insularis, Dolichozele koebelei and Exasticolus sp. nov. This is the first report of Colpotrochiasp. nov., Dolichozele koebelei and Exasticolus sp. nov. parasitizing S. frugiperda. From larvae of D. famulata emergedthe Braconidae: Cotesia sp., Glyptapanteles sp., Phanerotoma sp. (Group Fuscovaria) and Chelonus (Microchelonus)sp. nov. (first occurrence in D. famulata).
