1. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

2. IMPLICAÇÕES DO MUTUALISMO TROFOBIÓTICO COM HEMÍPTEROS NA ATIVIDADE DE FORRAGEIO DE FORMIGAS ARBORÍCOLAS EM UM ECOSSISTEMA ARBÓREO MONTANO / IMPLICAÇÕES DO MUTUALISMO TROFOBIÓTICO COM HEMÍPTEROS NA ATIVIDADE DE FORRAGEIO DE FORMIGAS ARBORÍCOLAS EM UM ECOSSISTEMA ARBÓREO MONTANO
This study investigates a new case of trophobiotic interaction that occurs between ants and the herbivore Calloconophora pugionata, specialist of Myrcia obovata. In the first chapter we describe the trophobioses and analyze the benefits of the tending ants for treehopper survival and fecundity. Using an exclusion experiment we show that the absence of tendin

3. Mirmecofilia em Parrahasius polibetes (Lepidoptera: Lycaenidae) : historia natural, custos, seleção de planta hospedeira e beneficios da co-correncia com hemipteros mirmecofilos / Mymecophily ion Parrhansius polibetes (Lepidoptera: Lycaenidae) : natural history costs, host-plant selection, and benefits of co-ocurrece with myrmecophilous hemipterans
Ants are one of the most prominent groups of terrestrial organisms in terms of diversity, relative abundance and biomass. Their importance is due primarily to eusocial behavior combined with complex communication systems. Tropical foliage is rich in renewable feeding sources that promote ant foraging. As some of the most important predators on plants, ants s

4. Endossimbiose de Tetranychus evansi Baker e Pritchard (Acari: Tetranychidae) e a resposta de defesa induzida em tomateiro / Endosymbioses of Tetranychus evansi Baker and Pritchard (Acari: Tetranychidae) and tomato induced defence response
Interactions between arthropods and microorganisms have been receiving more attention due to the impact that these symbiotic associations causes on their macrosymbionts. Reproduction is the main biological parameters affected with cytoplasmic incompatibility and thelytokous parthenogenesis; however, endosymbionts can help arthropods to exploit host plants. I

5. Bases ecológicas para o manejo de Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae) em sistemas orgânicos de produção de tomate
The whitefly Bemisia tabaci biotype B stands out, among the diverse community of pest herbivores that colonize the tomato crop, due to the direct damages and transmission of several pathogenic viruses (Geminiviridae) causing productivity losses. The spraying of insecticides for its control selects resistant populations and promotes the dispersion of adults t

6. Herbivoria, quantidade e qualidade de recursos em Calotropis procera (AIT.) R. BR. (Apocynaceae) / Spacial distribution, height and populational density of Calotropis procera (Ait.) R. Br. (Apocynaceae) and itÂs effects on herbivory
A presenÃa de insetos herbÃvoros està primariamente limitada pela presenÃa de sua planta hospedeira. Neste manuscrito foram testadas trÃs hipÃteses que foram utilizadas para tentar explicar como à mediada a herbivoria em plantas de Calotropis procera (Ait.)R.Br. numa Ãrea de Caatinga. SÃo elas: 1) HipÃtese da distribuiÃÃo espacial da planta hospe

7. Estudo das interaÃÃes planta-herbÃvoro em Laguncularia racemosa (L.) GAERTEN (COMBRETACEAE) no manguezal de MaracaÃpe, Ipojuca, PE
Interspecific competition is an important force in the ecology of the populations and communities of herbivores. An example that has been neglected is the competition between inductors of gall. These if characterize for being an atypical fabric transformation and/or vegetal agency, being able to be caused by mites, insects, etc. Better to understand the inte

8. Insecticide and fungicide activity of the ethanolic extracts of Pachira aquatica in Aubl Hypothenemus hampei (Ferrari) and Fusarium sp / ATIVIDADE INSETICIDA E FUNGICIDA DO EXTRATO ETANÓLICO DE Pachira aquatica AUBL SOBRE Hypothenemus hampei (FERRARI) E Fusarium sp
The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae), is considered as one of the principals plagues of the coffee tree, attacking the fruits all maturation phases. It possesses a short biological cycle and has a great capacity of proliferation, thus causing a phytossanitary problem in all the producing regions of coffee. Initial ef

9. Galhas entomÃgenas em Miconia prasina (SW.) DC (Melastomataceae) em fragmentos de Floresta AtlÃntica Nordestina
The objective of this work was to compare the frequency of galls occurring in Miconia prasina (Melastomataceae) in four remnants of Atlantic forest of northeastern Brazil. Insect galls were observed in M. prasina of the elliptic type, spherical and fusiform in the four studied fragments: a cylindrical in the RefÃgio Charles Darwin and a piriform type in the

10. Contrasting dynamics in the same plant–herbivore interaction
Long-term studies of two-species interactions under field conditions are unusual; most long-term field studies are of single species dynamics (1–6). Concurrent long-term studies on the dynamics of the same two interacting species in different locations are very rare. This result has led to the tacit assumption that different cases of the same two-species i

11. Chemical phenotype matching between a plant and its insect herbivore
Two potential outcomes of a coevolutionary interaction are an escalating arms race and stable cycling. The general expectation has been that arms races predominate in cases of polygenic inheritance of resistance traits and permanent cycling predominates in cases in which resistance is controlled by major genes. In the interaction between Depressaria pastinac

12. A Plasma Membrane Protein from Zea mays Binds with the Herbivore Elicitor Volicitin
Volicitin (17-hydroxylinolenoyl-l-Gln) present in the regurgitant of Spodoptera exigua (beet armyworm caterpillars) activates the emission of volatile organic compounds (VOCs) when in contact with damaged Zea mays cv Delprim (maize) leaves. VOC emissions in turn serve as a signaling defense for the plant by attracting female parasitic wasps that prey on herb
