1. No fitness costs are induced by Spiroplasma infections of Aphis citricidus reared on two different host plants
Resumo Pulgões podem abrigar vários simbiontes secundários que alteram características ecológicas importantes, como defesa contra inimigos naturais, tolerância ao calor e utilização da planta hospedeira. Um desses simbiontes secundários, Spiroplasma, é estudado em Drosophila por alterar a razão sexual e interagir com o sistema imunológico do hosp

2. DIVERSITY OF ARBUSCULAR MYCORRHIZAL FUNGI IN FOREST ECOSYSTEMS OF BRAZIL: A REVIEW
ABSTRACT Plants can stablish symbiosis with arburcular mycorrhiza fungi (AMF), in which the fungus uses carbohydrates synthesized by plant photosynthesis in exchange for soil nutrients. AMF symbiosis may benefit plants by increasing the rates of nutrient uptake, tolerance to abiotic stresses, protection against pathogens and, by promoting resilience of fores

hrpZ gene fromPseudomonas syringae pv.maculicola M2Pseudomonas syringae pv.maculicola is a natural pathogen of members of the Brassicaceae plant family. Using a transposon-based mutagenesis strategy inPseudomonas syringae pv.maculicola M2 (PsmM2), we conducted a genetic screen to identify mutants that were capable of growing in M9 mediuBraz. J.

4. Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert
Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert. The spatial distribution of the immature stages of the leaf miner Angelabella tecomae Vargas & Parra, 2005 was determined at two intra-plant levels (shoot and leaflet) on the shrub Tecoma fulva fulva (Cav.)

5. Biological traits and Life table parameters A and B biotype of Bemisia tabaci (Genn.) on cotton and rapeseed
The aim of this work was to construct life table of Bemisia tabaci (Gen.) A and B (silverleaf whitefly B. argentifolii Bellows and Perring) biotype (Hem.: Aleyrodidae) on two host plants; cotton, (Gossypium hirsutum L.) and rapeseed, (Brassica napus L.). Experiments were conducted in a growth chamber under 24 ± 2ºC, 55±3% RH and 16:8 (L:D) h photoperiod o

6. Analysis of 16S rRNA and mxaF genes reveling insights into Methylobacterium niche-specific plant association
The genus Methylobacterium comprises pink-pigmented facultative methylotrophic (PPFM) bacteria, known to be an important plant-associated bacterial group. Species of this group, described as plant-nodulating, have the dual capacity of producing cytokinin and enzymes, such as pectinase and cellulase, involved in systemic resistance induction and nitrogen fixa

7. Reproductive behaviours and host plant selection mediated by semiochemicals in Neoleucinodes elegantalis (Lepidoptera: Crambidae) / Comportamento reprodutivo e seleção de hospedeiro mediada por semioquímicos em Neoleucinodes elegantalis (Lepidoptera: Crambidae)
The searching behaviour in insects is important to acquire food, meeting mates, oviposition sites location and protect the insects against predators. Thus, the majority of herbivorous insects select their host plant and, in particular, the plants part, which it will feed and oviposit on, using, among other tools, host plants semiochemicals. This paper aims:

8. Performance consequences of food mixing in two passion vine leaf-footed bugs, Holymenia clavigera Herbst, 1784 and Anisoscelis foliacea marginella Dallas, 1852 (Hemiptera : Coreidae) / Conseqüências da dieta mista na performance de dois coreídeos do maracujá, Holymenia clavigera Herbst, 1784 and Anisoscelis foliacea marginella Dallas, 1852 (Hemiptera : Coreidae)
Holymenia clavigera (Herbst) e Anisoscelis foliacea marginella (Dallas) (Hemiptera: Coreidae: Anisoscelini) ocorrem no sul do Brasil e são hóspedes de diversas espécies de Passifloraceae. Observações preliminares indicam uma alta coexistência destas espécies em termos de uso da planta hospedeira; em adição, ovos e ninfas são extremamente semelhante

9. 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

10. Seleção de genótipos resistentes de amendoinzeiro a Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) com base em análises multivariadas
The velvetbean caterpillar Anticarsia gemmatalis Hübner attacks peanut leaves, and the use of resistant varieties has directly contributed to ecological and economic aspects of pest control. The aim of this work was to select resistant peanut genotypes to A. gemmatalis using cluster analyses (dendogram obtained by Ward's methods and K-means) and Principal C

11. Architectural changes in larval leaf shelters of Noctuana haematospila (Lepidoptera: Hesperiidae) between host plant species with different leaf thicknesses
Insect-food-plant associations have been shown to be influenced by the chemical, physical and nutritional characteristics of plants. We suggest that among insect larvae that use leaf material to build shelters, food-plant use may be constrained by differences in host leaf structure, illuminating a rarely investigated aspect of insect-plant interactions.

12. História natural da erva-de-passarinho Psittacanthus robustus (Loranthaceae) em uma área de campo rupestre do sudeste brasileiro : interações com hospedeiras, dispersores, polinizadores e insetos herbívoros / Natural history of the mistletoe Psittacanthus robustus (Loranthaceae) at a rupestrian filed site in southeastern Brazil : interactions with hosts, seed dispersers, pollinators and insect herbivores
In this study I investigated some aspects of the natural history of the woody mistletoe Psittacanthus robustus Mart. (Loranthaceae) in rocky outcrops in the Serra do Cipó, southeastern Brazil. This species was recorded parasitizing eight host species in Five families, although trees within Vochysiaceae comprise the main hosts. Pattern of distribution was cl
