1. Silverleaf whitefly-resistant common beans: an investigation of antibiosis and/or antixenosis
ABSTRACT The silverleaf whitefly Bemisia tabaci biotype B is one of the most important sucking pests of common bean, which causes severe damages and requires frequently synthetic insecticides spraying to protect crop productivity. The use of common bean cultivars resistant to whitefly attack is an important strategy within an integrated pest management (IPM)

2. ENDOPHYTIC FUNGI COMMUNITY IN Eremanthus erythropappus TREE FROM ANTHROPOGENIC AND NATURAL AREAS OF MINAS GERAIS
ABSTRACT It is know that many plants live in symbiosis with microorganisms that can be found on their interior, the endophytes. Environment and tissue type are modulating factors of this community, in which most of these microorganisms produce important antimicrobial molecules and they may be powerful biocontrol agents in agriculture. Thus, the aim of this s

3. Development of Oryzophagus oryzae (Costa Lima) in rice cultivars
RESUMO Cultivares resistentes a insetos são essenciais à melhoria do manejo de pragas como Oryzophagus oryzae (Coleoptera: Curculionidae), altamente prejudicial à cultura do arroz irrigado por inundação. O grau de benefício, porém, depende do tipo de resistência. Objetivou-se avaliar cultivares de arroz quanto à resistência a O. oryzae, inferindo

4. Morphological identification of Ilyonectria liriodendri and its interaction with plant growth-promoting bacteria in grapevine rootstocks
Resumo Com a finalidade de analisar a patogenicidade e o antagonismo entre porta-enxertos de videiras e microrganismos de solo, procedeu-se à seleção de bactérias promotoras de crescimento de plantas com efeito antibiótico ao fitopatógeno Ilyonectria liriodendri, isolado monospórico 2T-VSC-101, em testes de antibiose in vitro. O acesso bacteriano que

5. Identificação e seleção de espécies de Trichoderma spp. endofíticos de bromélias de restingas como agentes de biocontrole da fusariose em frutos de abacaxi
RESUMO Uma das doenças fúngicas de grande importância que ataca a cultura do abacaxizeiro é a fusariose, causado pelo fungo Fusarium guttiforme. A utilização do Trichoderma spp, que são fungos habitantes do solo e de ocorrência natural na forma endofítica em bromélias, ainda não foi estudada visando o biocontrole da gomose do abacaxizeiro. O traba

6. A915.34.01.08 - melon line resistant to leafminer (Liriomyza sativae)
Abstract Line A915.34.01.08 is a new source of resistance to Liriomyza sativae in melon. It was obtained by the genealogical method from a heterozygous plant with antibiosis type of resistance found within the accession CNPH 00-915. This line allows making introgression of this resistance in melon lines to develop commercial hybrids.

7. Resistance of sugarcane cultivars to Mahanarva fimbriolata
ABSTRACT The spittlebug Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) is one of the most important pest of sugarcane in Brazil. Population control measures are currently restricted to the use of chemical insecticides and the fungus Metarhizium anisopliae, in part because very little information exists regarding the resistance of sugarcane cultivars.

8. Polyphasic characterization of bacteria obtained from upland rice cultivated in Cerrado soil
ABSTRACT This work aimed to characterize 20 isolates obtained from upland rice plants, based on phenotypic (morphology, enzymatic activity, inorganic phosphate solubilization, carbon source use, antagonism), genotypic assays (16S rRNA sequencing) and plant growth promotion. Results showed a great morphological, metabolic and genetic variability among bacteri

9. Evaluation of forage grass resistance to Mahanarva fimbriolata (Stål)
ABSTRACT The aim of this study was to select forage grasses with potential resistance to Mahanarva fimbriolata by assessing effects on insect. No-choice assays were conducted with 12 genotypes and laboratory-reared insects. The following parameters were assessed: mortality and duration of the nymphal stage; adult weight and longevity; pre-oviposition period;

10. Bacterial selection for biological control of plant disease: criterion determination and validation
Abstract This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial compounds (ammonia and antibiosis) and hydrolytic enzymes

12. Antibiosis of Trichoderma spp strains native to northeastern Mexico against the pathogenic fungus Macrophomina phaseolina
Abstract Sampling of agricultural soils from the Mexican northeastern region was performed to detect Trichoderma spp., genetically characterize it, and assess its potential use as a biologic control agent against Macrophomina phaseolina. M. phaseolina is a phytopathogen that attacks over 500 species of cultivated plants and causes heavy losses in the regiona
