Biology of Spodoptera eridania and Spodoptera cosmioides (Lepidoptera: Noctuidae) on different host plants
Florida Entomologist 100 (4), 752-760
Abstract: The moths Spodoptera eridania (Stoll) and Spodoptera cosmioides (Walker) are pests of increasing importance in various grain production systems, causing defoliation and damage to reproductive structures of plants. This fact underscores the need for studies that analyze the nutrition and development of pests on different hosts. The objective of this study was to evaluate the development of S. eridania and S. cosmioides feeding on different host species. To this end, newly hatched larvae were separated individually into waxed cups and fed soybean, cotton, maize, wheat, oat leaves, or an artificial diet as control. The evaluated parameters were: duration of larval, pre-pupal, and pupal development (days), pupal weight (g), sex ratio (%), larvae-adult survival (%), oviposition preference, larval feeding performance, and weight gain on different hosts. Soybean and cotton were found to be more suitable hosts for development and oviposition of S. eridania and S. cosmioides than oat, wheat, and maize, all of which negatively affected larval development and survival. The maize cultivar 'DKB 390' did not allow for larvae to develop to adults and therefore proved to be inadequate for both studied Spodoptera species.
