| O objetivo deste trabalho foi elaborar um inventário das espécies de coleópteros fitófagos que utilizam como hospedeiras plantas do gênero Spondias spp., pertencente à família Anacardiaceae, dando ênfase à biodiversidade e aos hábitos alimentares desses insetos. Para tanto, diversas fontes de estudo foram consultadas, incluindo importantes obras de referência, além de publicações técnico-científicas. Levantamentos de ocorrências de algumas espécies foram realizados em pomar de cajazeira no Campo Experimental da Embrapa, localizado em Pacajus, Ceará. Diante dos resultados obtidos, conclui-se que: 1. Os insetos da ordem Coleoptera que são fitófagos de Spondias spp. apresentam um total de 08 espécies, pertencentes a sete famílias diferentes, as quais atacam... |

| Abstract: As a part of our continuing search for insect and arthropod development regulators from Brazilian restinga vegetation of the Rio de Janeiro State, crude extracts, purified fractions and essential oils were submitted to screening tests seeking for biological activities on the development of the insects Rhodnius prolixus, Dysdercus peruvianus, Oncopeltus fasciatus and Rhipicephalus (Boophilus) microplus. Up to now, 102 secondary metabolites have been detected in the fractions, among them monoterpenes, sesquiterpenes and two triterpenes which were obtained from the species, Eugenia sulcata, Pilocarpus spicatus, Manilkara subsericea, Myrciaria floribunda and Zanthoxylum caribaeum. These secondary plant metabolites are considered of interest for the... |

| ABSTRACT The oil palm is an economically important crop cultivated in the North of Brazil. Damage caused by insects is one of the main causes of reduced productivity for the oil palm. Before this research, only the beetles of the family Curculionidae were considered to be oil palm pests in Brazil. However, for the first time, we report on the damage caused by a giant rhinoceros beetle to oil palm plantations in Pará, Brazil. The beetle was identified as Golofa claviger (Linnaeus, 1771), which has a single record in Brazil (Pará) but is widely distributed in South America. The species occurs in an unprecedentedly high abundance of local specimens. The attacks are concentrated on the central cluster of young palms. Feeding behavior is identified as the main... |

| The aim of this study was to verify the resistance of tomato genotypes (crossed with Solanum galapagense) to the green peach aphid, Myzus persicae, and the association of this resistance with glandular trichomes. Leaf trichomes were quantified for seven F2 genotypes of the BPX-486 population derived from crossing S. lycopersicum ‘TOM-684’ and S. galapagense accession ‘LA-1401’, for the commercial controls ‘TOM-584’ and ‘Santa Clara’, and for the accession ‘LA-1401’. After this evaluation, the genotypes were subjected to two nonpreference resistance tests of the green peach aphid in the laboratory, one with choice and the other without choice. Five genotypes (BPX-486-17, BPX-486-62, BPX-486-10, BPX-486-46, and BPX-486-08) and the accession LA-1401... |

| ABSTRACT: The cultivation of transgenic soybean plants using the glyphosate resistant gene (RR soybeans), takes up about 47% of the world’s cropping area. Despite the large area planted with soybeans resistant to glyphosate, there are very few studies of the environmental impact of this technology, especially in tropical areas. Thus, this study aimed to evaluate the impact of the cultive of RR soybeans and the use of glyphosate on the community of soil surface arthropods. The experiment was conducted in Coimbra, Minas Gerais state for two agricultural years. The experimental design was conducted in randomized blocks with five replications. The treatments were: non-transgenic soybean with mechanical weeding; RR soybean with mechanical weeding; RR soybean... |
