Uma chave para identificação de Dilobopterus costalimai Young, Acrogonia sp., Oncometopia facialis (Signoret), Bucephalogonia xanthophis (Berg) e Plesiommata corniculata Young baseada em caracteres morfológicos externos e na genitália masculina é apresentada. Essas cigarrinhas são vetoras de Xylella fastidiosa em citros. As quatro primeiras espécies são coletadas em diversos hábitats como pomar, mata, várzea, brejo, cana-de-açúcar, café, enquanto P. corniculata ocorre principalmente em gramíneas, Brachiaria decumbens Stapf, Cynodon dactylon (L.) Pers. |

ABSTRACT The cultivation of genetically modified crops in Brazil has led to the need to assess the impacts of this technology on non-target species. Under field conditions, the potential effect on insect biodiversity was evaluated by comparing a homogeneous corn field with conventional and transgenic maize, expressing different Bt proteins in seven counties of Minas Gerais, Brazil. The richness pattern of non-target insect species, secondary pests and natural enemies were observed. The results do not support the hypothesis that Bt protein affects insect biodiversity. The richness and diversity data of insects studied were dependent on the location and other factors, such as the use of insecticides, which may be a major factor where they are used. |
