“…In Brazil, besides maize, there is the possibility that these two species could cohabit in other economically important crops such as soybean, cotton, tomatoes, dry beans, among others [5, 6, 24]. However, maize represents a model crop to study the interaction between these two pests.…”

Battle in the New World: Helicoverpa armigera versus Helicoverpa zea (Lepidoptera: Noctuidae)

The corn earworm Helicoverpa zea (Boddie) and the old world bollworm Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) are allopatric species and occur in important agricultural crops. In maize, both species tend to infest the ear. The introduction of H. armigera in Brazil has created a new scenario, where these Helicoverpa species might cohabit and interact with one another, affecting the prevalence of each species in the agroecosystem, integrated pest management, and insect resistance management. In this study, larval occurrence and proportion of these species in maize was assessed in three regions of Brazil during three crop seasons. Interaction between the species was evaluated in interspecific and intraspecific scenarios under laboratory and field conditions. Helicoverpa zea was predominant in Rio Grande do Sul and the Planaltina, DF (central Brazil). In western Bahia, H. zea was predominant in the first collection, but approximately equal in number to H armigera in the second crop season. Both species exhibit high cannibalism/predation rates, and larval size was the primary factor for larval survival in the interaction studies. Larva of H. zea had higher survival when interacting with H. armigera, indicating that H. zea has an advantage in intraguild interactions with H. armigera in maize. Overall, the results from this study indicate that maize might play a role as a source of infestation or a sink of insecticide or Bt protein unselected H. armigera populations, depending on the H. zea:H. armigera intraguild competition and adult movement in the landscape.

“…Specht et al (2013) ampliaram o registro de ocorrência e apresentaram a caracterização morfológica e molecular da praga. Recentemente, também foi relatada a ocorrência deste inseto em cultivos de tomate, no Estado do Espírito Santo (Pratissoli et al, 2015). Lagartas recém-eclodidas de H. armigera alimentam-se de folhas e partes tenras do tomateiro até atingirem o terceiro instar ou até os cinco dias de idade.…”

Resumo: O objetivo deste trabalho foi verificar a resistência à lagarta Helicoverpa armigera (Lepidoptera: Noctuidae), em genótipos de tomateiro obtidos do cruzamento interespecífico de Solanum lycopersicum x S. galapagense, e a associação dessa resistência com a densidade de tricomas glandulares do tipo IV. Genótipos da população F2, derivada do cruzamento S. lycopersicum TOM-684 x S. galapagense LA-1401, selecionados quanto à baixa e à alta densidade de tricomas glandulares, respectivamente, foram submetidos a dois testes de resistência à lagarta H. armigera em laboratório, um de antibiose e outro de antixenose. Os genótipos da população F2, com alta densidade de tricomas glandulares do tipo IV (BPX-486-17, BPX-486-62, BPX-486-10, BPX-486-46 e BPX-486-08), apresentam maiores níveis de resistência, tanto por antibiose quanto por antixenose, do que os genótipos com baixa densidade de tricomas glandulares (BPX-486-313 e BPX-486-383) e do que as testemunhas 'Santa Clara' e TOM-684. Os níveis de resistência foram menores do que os do genitor silvestre LA-1401.

“…9, No. 6;2017 In recent years, H. armigera has been reported in different crops and Americas regions, and this new record in millet should reinforce attention with this pest in off-season crops (Czepak, Albernaz, Vivan, Guimarães, & Carvalhais, 2013;Specht, Sosa-Gómez, Paula-Moraes, & Yano, 2013;Murúa et al, 2014;Pratissoli, Lima, Pirovani, & Lima, 2015;Kriticos et al, 2015;Krinski & Godoy, 2015).…”

This study evaluated the occurrence of lepidopteran pests on millet cultivated in off-season in the state of Mato Grosso, Brazil. Larvae were collected from May to July 2013 in an area of 145 hectares located in Tangará da Serra, MT. After being collected, caterpillars were kept in the laboratory and fed an artificial diet until the pupal stage. After emergence, adults were dry mounted, identified, and deposited in the entomological collection of Embrapa Cerrados, Planaltina, Distrito Federal, Brazil. Adults obtained from 117 caterpillars were identified as Mocis latipes (Guenée), Spodoptera frugiperda (J.E. Smith), Helicoverpa armigera (Hübner), H. zea (Boddie), Mythimna (Pseudaletia) sequax Franclemont, Urbanus proteus (Linnaeus), and Leucania latiuscula Herrich-Schäffer. This study describes the first record of lepidopteran pests on millet plants in the state of Mato Grosso, and the incidence of lepidopterans in the system that uses millet as cover crop represents a risk of the occurrence of insect pests on subsequent crops on the straw of this grass.
