A 6-year field monitoring study was designed to compare the presence of fall armyworm Spodoptera frugiperda (J. E. Smith), leaf injury, its parasitoids, 100 seed weight, and seed yield of Bt maize hybrids approved for commercialization in the Brazilian market. Field trials were planted in two municipalities, divided into two periods, from 2011 to 2014 (period I), and due to the approval of different Bt hybrids, from 2015 to 2016 (period II). Treatments were Bt, non-Bt maize and all non-Bt maize sprayed with insecticide methomyl. Six Bt-maize hybrids were planted, expressing the following proteins: Cry1Ab, Cry1F, Cry1A.105 (Cry1Ab +Cry1Ac +Cry1F), Cry2Ab2a and Vip3. In 2015 and 2016 Bt Powercore was planted due to its commercial approval. The number of S. frugiperda larvae for most Bt hybrids was lower than on non-Bt hybrids, except for Fórmula TL and Herculex in period II, in both municipalities. In period I, Bt hybrids VT, VT 2 and Viptera showed almost no injury on their leaves, despite the high number of fall armyworm larvae found in plants. Different parasitoids emerged from larvae from Bt and non Bt hybrids: Archytas sp., Campoletis sp., Chelonus sp., Eiphosoma sp. and Ophion luteus. The average 100 seed weight was higher in municipality from Sete Lagoas for all Bt hybrids, non-Bt hybrids and non-Bt hybrids sprayed with methomyl, when compared to Nova Porteirinha during period I. Fórmula TL, non-Bt Fórmula TL sprayed with methomyl, and non-Bt Fórmula TL showed the lowest seed yield in both municipalities and periods.

RESUMO - Foram comparados cinco métodos de controle leiteiro: três métodos com registro da produção das duas ordenhas com frequência quinzenal (Q), mensal (M) e bimensal (B);e dois métodos (A e C) com registro da produção de apenas uma ordenha, alternando mensalmente a da manhã da tarde. Utilizaram-se os registros diários de produção de 509 lactações de vacas HPB, Jersey e mestiças HPB-Gir. Para 425 lactações de 176 vacas, foi possível corrigir a produção total por idade e grau de sangue, e expressá-la como desvio das companheiras contemporâneas. Para efeitos de seleção por produção de leite, todos os métodos estudados resultaram em ganho genético similar, tanto por parte das vacas quanto por parte dos touros, podendo ficar, então, a escolha entre eles, apenas na dependência de considerações práticas. ABSTRACT - Five milk recording methods were compared: three methods with register of the production 01 two milkings with blweekiy (6W), monthiy IM) and bimonthly (BM) frequency; and two methods (A &C) with register of onlyone milking, alternating the morning and afternoon milkings monthly. The daily production records of 509 lactations of HPB, Jersey and rnixed HPB-Gir cows were used. For 425 Iactations of 176 cows, it was possible to correct the total production by age and blood degree, and to express It as a deviation from the contemporary companions. For effects aI selection on milk production, ali the methads studied resulted in a similar genetic gain, for cows as well as for bulls, enabling the choice between them to be made solely on the basís of practical considerations.
