【 摘 要 】

The aim of thisstudy was to identify the defoliating lepidopterans and their parasitoids occurringon okra plants in the district of Riberão Preto city (SP. Brazil). Caterpillarswere collected by hand from an experimental field of okra, in March and April,2009. They were placed individually on Petri dishes lined with wet filter paper,containing shredded okra leaves, and kept in a climactic chamber (25±1°C,12:12h light/dark photoperiod, RH 70±10%) until the emergence of lepidopteransand/or parasitoids. In all, 63 lepidopterans were obtained: three species ofNoctuidae, Anomis flava (Fabricius), Spodoptera frugiperda(Smith) and Pseudoplusia includens (Walker); one of Pieridae,Ascia monuste orseis (Godart), and an unidentified species ofTortricidae. One unidentified tachinid fly (Diptera) and the Hymenoptera parasitoidsCopidosoma floridanum (Ashmead) (Encyrtidae) and Euplectrussp. (Eulophidae) emerged from A. flava, while C. floridanumand an unidentified tachinid, from P. includens. This is the firstreport of an association between the herbivores S. frugiperda,P. includens and A. monuste orceis, the parasitoidsC. floridanum and Euplectrus sp. on okra plants.
