| O objetivo deste trabalho foi avaliar a ocorrência do microácaro-da-face-inferior-das-folhas-de-milho Catarhinus tricholaenae Keifer (Acari: Diptilomiopidae) em cultivares transgênicas de milho, contendo as proteínas Cry1F e Cry 1 A(b) e milho não Bt. Durante o período de junho de 2010 a janeiro de 2011, foram coletadas, quinzenalmente, cinco amostras aleatórias de quatro folhas em talhões de milho Bt, contendo a proteína Cry 1F e Cry 1 A(b), e de milho não Bt em áreas experimentais da Embrapa Milho e Sorgo, em Sete Lagoas, MG. As amostras de folhas foram vistoriadas por 15 minutos na região da nervura central, em busca de adultos de C. tricholaenae. Foram registrados 2.930 indivíduos de C. tricholaenae, sendo que 1.114 no milho Bt Cry 1F, 753 em Cry 1... |

| ABSTRACT: The study of non-target organisms such as mites, can provide information about the possible effects of transgenic maize cultivars on the arthropod community. This study aimed to evaluate the abundance of phytophagous mites in the area of Bt maize and evaluate the instantaneous population growth rate, and food preference of phytophagous mites on Bt maize. We registered the species occurrence and the number of adult mite individuals on four maize cultivars, one non-Bt 30F35, and three containing the proteins Cry1Ab (30F35 Yg), Cry1F (30F35 Hx) and Vip3a (Impacto Viptera). Cry proteins disrupt the midgut epithelium of insect pests. The food preference and instantaneous population growth rate (ri) were evaluated using the two-spotted spider mite... |

| Abstract: The objective of this work was to survey soil ants in Bt and non-Bt maize (Zea mays) crops, and to compare their effect on the soil ant community. Nine pitfall traps, 10 m apart, were installed in a central area (900 m2) of each of the following treatments (2,500 m2): conventional maize; maize modified with the Cry1F, Cry1Ab, and Vip3A proteins; and a native vegetation area. Fortnightly collections were conducted during four periods (complete producing cycles) of the crop, from 2011 to 2013. The number of ant species varied from 25 in Bt maize (Vip 3A) to 58 in Bt maize (Cry 1F). The treatment with conventional maize showed the highest Shannon-Wiener diversity index (H’ = 2.60). Jaccard’s index showed that there is dissimilarity between the... |
