Popis: | The objective of this study was to compare growth and development of Helicoverpa zea Boddie and Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) larvae that were feeding on an artificial diet. Neonate larvae of H. zea and H. armigera were collected in maize fields cultivated at the Brazilian Agricultural Research Corporation, Embrapa Maize & Sorghum, in Sete Lagoas (Minas Gerais) and in farmers' cotton fields in Luís Eduardo Magalhães (Bahia), respectively. Bioassays were conducted in the laboratory using individual larvae in 50 mL plastic cups fed a white bean'based artificial diet and maintained at a temperature of 26 ± 2 °C and a relative humidity of 47 ± 10%. The following larval biological parameters were evaluated: number and duration of instars, survival of larval instars and pupae, larval biomass, larval head capsule size, and larval length. An adaptation index was computed for comparison of development of the 2 species. Significant differences were observed between the species for all variables except for the number of instars and pupal survival. Although H. armigera larvae developed faster and were smaller than H. zea larvae, the diet tested can be considered adequate for rearing both species in the laboratory. |
