1. Floral Scent and Nectar Sugar Composition of Temnadenia odorifera (Apocynoideae, Apocynaceae)
Temnadenia odorifera is an endemic species from the Brazilian Atlantic Forest. This study was developed in order to identify the volatile compounds emitted by the living flowers and nectar, to evaluate the temporal pattern of scent emission, and the sugars composition of its nectar. Analyses of the flower scent by dynamic headspace in vivo, of nectar sugar c

2. The diversity of citrus endophytic bacteria and their interactions with Xylella fastidiosa and host plants
Abstract The bacterium Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC) and has been associated with important losses in commercial orchards of all sweet orange [Citrus sinensis (L.)] cultivars. The development of this disease depends on the environmental conditions, including the endophytic microbial community associated with the

3. Host plants of insect-induced galls in areas of cerrado in the state of Goiás, Brazil
Most studies of the interactions between plants and gall-inducing (galling) insects have focused on the entomological aspects, few having addressed the diversity of galls in relation to the characteristics of the host plants. The objective of this study was to analyze the richness and composition of the community of host plants of galls in areas of cerrado (

4. Flower-visiting insects of five tree species in a restored area of semideciduous seasonal forest
The reinstatement of biodiversity and ecological processes must be the major goal in restoration projects, which requires the establishment of biological interactions in addition to native plant population recovery. Therefore, we assessed the flower visitors of five tree species in a restored area of Semideciduous Seasonal Forest, in Ribeirão Preto, SP, Bra

5. 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

6. Estudo de interações de parasitoides de insetos endófagos em frutos do cerrado
Interactions between endofagous insects in fruits play an important role in ecological communities, since the seed survivorship and hence the successes in recruitment of plant populations are directed related to damage caused by the herbivory from these insects. Because of the specialization of the herbivorous insects, the insect-plant interactions tend to b

7. Interações ecológicas em Malpighiaceae no cerrado: compartilhamento de guildas de herbívoros e variações nos resultados da interação formiga-planta / Ecological interactions in Malpighiaceae in the Cerrado: sharing of guilds from herbivores and variations in the results of ant-plant interaction
Ecological interactions represent essential tools for a better understanding of natural communities, having in animal-plant relationships important models for study. For that, become needful phenological analyses of plants, capable of demonstrating the flowering strategies and with it the ways of temporal organization of resources available for herbivores. T

8. Interaction of Metarhizium anisopliae (Metsch), Beauveria bassiana (Bals.) and granulovirus, the main pathogens of Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae) / Interação de Metarhizium anisopliae (Metsch.), Beauveria bassiana (Bals.) e vírus da granulose, principais patógenos de Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is naturally infected by various pathogens, the most important are Metarhizium anisopliae (Metsch) (Ascomycota: Clavicipitaceae), Beauveria bassiana (Bals.) (Ascomycota: Cordycipitaceae) and granulovirus. These microorganisms may coinfect the same host under field conditions

9. Costs and benefits of ant attendance to the extrafloral nectaries of Crotalaria pallida (Fabaceae) / Custos e beneficios da visita de formigas aos nectarios extraflorais de Crotalaria pallida (Fabaceae)
Ants may have a positive or negative effect on the fitness of the plants with which they interact, depending on its relationship with herbivores, pollinators and seed dispersers. A remarkable characteristic of the interactions between ants and plants is the high frequency with which they are mutualistic. The supposed benefit of these interactions is that the

10. Experimental clipping of Chromolaena pungens (Asteraceae) and its multitrophic effects / Poda experimental de Chromolaena pungens (Asteraceae) e seus efeitos multitroficos
Natural or human-induced disturbances may promote plant phenotypic modifications, developmental and phenological changes which, in turn, may influence herbivores, predators and pollinators. Abiotic factors, especially nutrient availability, may also influence plant recovery. In this study, we evaluated plant regrowth and arthropod responses to experimental c

Examinei os efeitos da degradação antrópica sobre diferentes aspectos da diversidade de espécies e interações entre plantas da família Asteraceae e os insetos herbívoros cujas larvas se alimentam no interior de seus capítulos. Toda a amostragem de campo foi realizada em vinte áreas de cerrado com diferentes níveis de degradação antrópica em tr�

12. Insect serine-endopeptidases and plant-insect interactions / Serina endopeptidases de insetos e a interação inseto-planta
Serina endopeptidases de insetos, principalmente tripsinas e quimotripsinas, estão envolvidas na digestão inicial de proteínas. Genes codificadores para estas enzimas estão organizados em famílias multigênicas tendo expressão diferencial de acordo com a dieta do inseto, estando envolvidos no desenvolvimento de resistência a diferentes metabólitos se
