| O coqueiro, Cocos nucifera L. (Arecaceae), é um importante cultivo do nordeste brasileiro. É uma planta principalmente anemófila, porém numerosos insetos visitam suas inflorescências, nas diversas fases do florescimento e formação dos frutos, podendo interferir no processo de polinização. Há carência de estudos para verificar e determinar a eficiência desses artrópodos como polinizadores. Em coqueiros cultivados perto do litoral da Bahia, avaliou-se a capacidade de diferentes himenópteros (formigas e abelhas) de transportarem pólen no corpo, a fim de verificar sua contribuição para a polinização. Observou-se transporte significativo de pólen pelos dois grupos de insetos, sendo as abelhas perfeitamente aptas para polinizar a planta. Entre estas, espécies... |

| A technique for rearing Elasmopalpus lignosellus (Zeller),larvae in laboratory, infesting plants in the field and evaluating treatments was described and tested in rice. In addition, the performance of insecticides as seed treatments to control larvae, under artificial and natural infestations, was evaluated on three planting dates. The experimental design was a Latin 6x6 square and the experimental unit consisted of seven 4 m long rows and 0.4 m spacing between rows. Treatments consisted of the following insecticides and doses: thiamethoxam (52.5, 70, and 105 g a.i./100 kg seeds), furathiocarb (320 g a.i./100kg seeds), carbofuran (525 g a.i./100kg seeds), and an untreated control. Artificial infestations were made, in two groups of three selected tillers... |

| In order to visualize the distribution pattern of the neuronal bodies and neurofibrils in the honeybee brain, we adapted a metallic impregnation technique first described for vertebrate nervous system by Ramón y Cajal. The honeybee brain constitution plays a key role in the development of learning and memory capacities. The general characteristics observed in the honeybee brain, stained by metallic impregnation, revealed its anatomical and morphological constitution in agreement with studies of other insect brains using different techniques. Metallic impregnation evidenced the optic lobe neuropils, the ocelli fiber cells, the neuron extensions of the calyces, and the axon bundles that involve the antennal glomeruli, as well as the neuron extensions in the... |

| This study investigated the level of morphometric and genetic variability among populations of Anastrepha pickeli Lima from several localities in Brazil, one locality in Bolivia and one in Paraguay. Traditional and geometric morphometric analyses were used, as well as sequencing of a fragment of the cytochrome oxidase gene (COI). Six variables were measured from the aculeus for traditional morphometric analysis and 14 landmarks from the right wing were used for geometric analysis, using 10 specimes/population. The aculeus tip length, aculeus width at the end of the cloaca opening, and the serrate part length contributed with 62.7% for grouping. According to the results from traditional morphometry, there was no significant difference, but the multivariate... |

| A new genus, Podkova, is described from Brazil to accommodate its type-species P. hirsuta, sp. n. The genus has a peculiar appearance, the main features of which are the small compact body with coarsely pilose dorsal parts of the head and mesosoma, including median part of propodeum, head with sharp frontal carina of horse-shoe shape, delimiting broad facial cavity with rather short antennae, and a sharp occipital carina stretching posteriorly down along hind margins of eyes. By these features, Podkova resembles the genus Alachua Schauff and Boucek, but differs distinctly by having strong frontal carina on the head and the prepectus hardly overlapped by the anterior margin of mesosternum. Possible affinities to some other entedonine genera are discussed. |

| Integrated Pest Management (IPM) is a key component in the development of sustainable agro ecosystems. The Integrated Pest Management Collaborative Research Support Program (IPM CRSP) is a USAID funded project that is a consortium of U.S. universities working with host country national programs and other stakeholders to promote IPM globally. The IPM CRSP model is based on a Participatory Integrated Pest Management (PIPM) process that has as its goals to help reduce: agricultural losses due to pests, damage to natural eco-systems including loss of biodiversity, and pollution and contamination of food and water supplies. The IPM CRSP participatory model is based on networking, institution building, private sector interaction, research-technology development... |
