Resumo
Spodoptera cosmioides (Lepidoptera: Noctuidae)é uma espécie polífaga e alimenta-se de grande número de plantas cultivadas e espontâneas. No Brasil, as culturas do abacaxi, algodoeiro, arroz, berinjela, cebola, eucalipto, pimentão e tomateiro, entre outras hortaliças, são consideradas hospedeiras da praga. Entretanto, apesar da ampla gama de hospedeiros, sua ocorrência como praga é relatada relacionada a desequilíbrios provocados pelo uso excessivo de inseticidas de amplo espectro, o que vem causando a resistência da praga a inseticidas. Devido a essa complexidade, métodos alternativos de controle têm sido propostos, por exemplo, o controle biológico através da utilização de parasitóides. Trichospilus diatraeae (Hymenptera: Eulophidae) é um parasitóide gregário pupal preferencialmente de espécies da ordem Lepidoptera. Este é o primeiro relato de T. diatraeae parasitando pupas de S. cosmioides, parasitóide que oferece novas perspectivas para os programas de controle biológico.
Spodoptera cosmioides (Lepidoptera: Noctuidae) is a polyphagous species and feeds on many wild and cultivated plants. In Brazil, the crops of pineapple, cotton, rice, eggplant, onions, eucalyptus, bell pepper and tomato, among other vegetables, are considered to be host of the pest. However, despite the wide host range, its occurrence as a pest is reported related to imbalances caused by excessive use of broad-spectrum insecticides, which is causing pest resistance to insecticides. Because of this complexity, alternative control methods have been proposed, for example, biological control using parasitoids. Trichospilus diatraeae (Hymenptera: Eulophidae) is a gregarious pupal parasitoid species, preferably from the order Lepidoptera. This is the first report of 7: diatraeae parasitizing pupae of S. cosmioides, parasitoid offers new prospects for biological control programs.
