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. Diurnal Pattern of Leaf, Flower and Fruit Specific Ambient Volatiles above an Oil Palm Plantation in Pará State, Brazil
Oil palm plantations are rapidly expanding in the tropics because of insatiable global demand for fruit oil to be used in food, biofuels and cosmetics. Here we show that three tissue-specific volatiles can be quantified in ambient air above an African-American hybrid oil palm plantation in Brazil and linked photosynthesis (isoprene), floral scent (estragole)

4. New evidences supporting trophobiosis between populations of Edessa rufomarginata (Heteroptera: Pentatomidae) and Camponotus (Hymenoptera: Formicidae) ants
ABSTRACT Despite its important effect on the maintenance of tritrophic interactions among plants, insect herbivores, and ants, there is still a paucity of natural history and basic biology information involving trophobiosis among Heteroptera stink bugs. Here, based on previous observations of a new trophobiotic interaction between Edessa rufomarginata (De Ge

5. 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 (

6. A fragmentação florestal e a interação entre formigas e diásporos carnosos na floresta Atlântica / Forest fragmentation and the interaction between ants and fleshy diaspores in the Atlantic forest
Em florestas tropicais, formigas de folhiço são freqüentemente vistas em interação com diásporos vegetais (frutos e sementes). Em alguns casos, esta interação oportunista resulta em um mutualismo. Enquanto formigas se beneficiam ao alimentar-se de partes carnosas nutritivas (i.e., polpa, arilo), elas podem beneficiar a semente, por exemplo, ao aument

7. Predação de sementes em Erythrina falcata Benth. Fabaceae Faboideae: Biologia dos insetos predadores e estratégias de compensação da planta / Seed predation in Erythrina falcata Benth. Fabaceae - Faboideae: Biology of insect predators and plant compensation strategies
A produção de sementes é um importante estágio na história de vida das plantas, pois são estas as estruturas responsáveis pela reposição de indivíduos e também expansão e perpetuação das populações, funcionando também como meio de dispersão para colonização de áreas distantes de uma população. A Predação de sementes exercida por inse

8. 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

9. Plant - insect interactions and the biological control of weeds.
Muitos dos problemas de plantas daninhas mais serios no mundo originam-se apos a introducao de especies de plantas em ambientes exoticos. A introducao de inimigos naturais, particularmente insetos herbivoros, da regiao de distribuicao natural da planta, podera resultar em um bom nivel de controle, e e provavel que esta seja a unica solucao em muitos casos.

10. Caracterização estrutural da interação de serino proteinases de Spodoptera frugiperda (Lepidoptera: Noctuidae) e inibidores de proteinases de plantas / Structural characterisation of Spodoptera frugiperda (Lepidoptera: Noctuidae) serine proteinase interactions with plant proteinase inhibitors.
As plantas desenvolveram diferentes mecanismos para reduzir o ataque de insetos, incluindo compostos protéicos de defesa, como os inibidores de proteinases (IPs). Os insetos, ao longo da evolução, desenvolveram estratégias para superar as barreiras defensivas das plantas, permitindo a sua alimentação e desenvolvimento, como a super expressão de genes

11. Analysis of community structure of bees (Hymenoptera:apoidea) in an area of Caatinga do de BaturitÃ, CearÃ, Brazil / AnÃlises da estrutura da comunidade de abelhas (Hymenoptera: Apoidea) em uma Ãrea de caatinga do MaciÃo de BaturitÃ, CearÃ, Brasil
The great importance of bees as pollinators of several plant species has stimulated many investigations carried out on the organization and structure of their community. This type of study consist of describe the composition, abundance, richness, diversity, temporal variation of bees and their relationship with plants. The object of this study was to know th

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
