37. Otimização do manejo da pinta preta causada por Guignardia citricarpa Kiely na produção ecológica de tangerinas cv. Montenegrina sob a ótica da pesquisa participativa / Optimization of management techniques of black spot (Guignardia citricarpa Kiely.) in ecological orchards of tangerine trees cv. montenegrinafrom the perspective of participatory research
In the state of Rio Grande do Sul many citric species are grown, the town of Montenegro, in Vale do Caí/RS stands out among the most important producers. For the production of fruits for in natura consumption most of the local farmers adopt technological packages that consist in the use of chemical inputs and in environmetal simplification. However, experim

38. Diversidade genética entre híbridos de tangerina 'Cravo' e laranja 'Pêra'.
Marcadores moleculares RAPD foram utilizados para avaliar a diversidade genética em uma população de 94 híbridos de tangerina 'Cravo' (Citrus reticulata Blanco) com laranja 'Pêra' (C. sinensis (L.) Osbeck), obtidos por polinização controlada. Nas reações de amplificação foram usados 102 "primers" decâmeros de seqüência arbitrária, que amplific

39. Efeito dos extratos do albedo de Citrus sinensis, Lentinula edodes, Agaricus blazei e dos compostos orgânicos voláteis produzidos por Saccharomyces cerevisiae no controle da mancha preta dos citros / Effect of albedo extracts of Citrus sinensis, Lentinula edodes, Agaricus blazei and volatile organic compounds produced by Saccharomyces cerevisiae in the control of citrus black spot
The citrus black spot is a disease that restricts the export of Brazilian oranges to the countries in Europe. Except for Citrus aurantium and its hybrids, all other varieties are susceptible to the pathogen. Thus, there is great interest that this disease does not occur, since it is considered a quarantine A1 disease. Problems associated with the acquisition

40. Effect of conspecific and plant volatiles of Murraya paniculata (L.) JACK, Psidium guajava L. and Citrus sinensis (L.) Osbeck on the behavior OF Diaphorina citri Kuwayama (Hemiptera: Psyllidae) / Efeito dos coespecíficos e voláteis das plantas Murraya paniculata (L.) Jack, Psidium guajava L. e Citrus sinensis (L.) Osbeck sobre o comportamento de Diaphorina citri Kuwayama (Hemiptera:Psyllidae)
The agro-ecosystems consist of complex trophic relationships between plants, herbivores and their natural enemies. It is known that the majority of plants can produce volatiles compounds used as chemical signals by different groups of insects. These compounds can be produced constitutively in healthy plants, i.e., without induction. In other hand, the produc

41. Conservação refrigerada de lima ácida "Tahiti" em combinação com atmosfera modificada, ácido giberélico e permanganato de potássio / Cold storage Tahiti lime in combination with modified atmosphere, gibberellic acid and potassium permanganate
Although Brazil is the largest producer and exporter of Tahitilime, actually, exports only 5% of total production. This is, in part, because of a lack of quality of these limes, characterized by loss of green skin colour after harvest. The purpose of this research was to evaluate the efficiency of modified atmosphere, gibberellic acid (GA) and potassium perm

42. Reproductive fitness of Pratylenchus spp. populations in different plant species / Avaliação da capacidade reprodutiva de populações de Pratylenchus spp. frente a diferentes espécies vegetais
Os nematoides que atualmente tem sido classificados como P. coffeae, demonstram ampla variabilidade morfológica, molecular e quanto à reação à diferentes hospedeiros. Por conseguinte, é essencial que se identifique corretamente as espécies e que se conheça a capacidade de parasitismo em alguns hospedeiros, para que se possa estabelecer medidas de con

43. Genetic transformation and pathogenicity of Guignardia citricarpa / Transformação genética e patogenicidade de Guignardia citricarpa
O Brasil é líder absoluto no comércio internacional de suco de laranja concentrado congelado participando com 82% do volume comercializado no mundo. Guignardia citricarpa é um fungo Ascomiceto agente causal da Mancha Preta dos Citros (MPC), uma doença importante no contexto da Citricultura, causando lesões negras em frutos tornando-os impróprios para

44. Relative susceptibility of citrus genotypes to fruit rot caused by Ceratocystis radicicola in Iran
Several citrus genotypes were evaluated for their relative susceptibility to the new lemon fruit rot pathogen, Ceratocystis radicicola. Wounded detached fruits were inoculated ten days before normal harvest by placing on the wound site a droplet of distilled water followed by a mycelial plug of one-week-old culture. Inoculated fruits were ranked for their re

45. Caracterização molecular e avaliação da resistência ao vírus da tristeza dos citros (CTV) em plantas transgênicas de laranja Valência(Citrus sinensis L. Osbeck) / Molecular characterization and resistance evaluation to citrus tristeza virus (CTV) in transgenic plants of Valência orange (Citrus sinensis L. Osbeck)
In Brazil, citrus is one of the most important cultures. The productivity of this culture in the country is still considered low and this fact is due to several pests and diseases that affect the crop. Among the diseases there is the tristeza, caused by Citrus tristeza virus (CTV). This pathogen can also be related with another important disease, the citrus

46. Detecção do vírus da leprose dos citros nos tecidos da planta infectada e do ácaro vetor Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae) / Detection of Citrus leprosis virus C (CiLV-C) in the tissues of infected plants and of mite vector Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae)
Citrus leprosis is one of the most important diseases in the Brazilian citrus production due to the wide occurrence in orchards and also to the high costs involved in the chemical control of the mite vector. The disease affects the plant production and longevity and it is characterized by localized chlorotic and/or necrotic spots on the leaves, stems and fru

The family Brassicaceae is one of the most economically important in the world, having as their main pest to Plutella xylostella (L.) (Lepidoptera: Plutellidae), which causes great damage to the crop with up to 100% of yield losses. In order to investigate alternatives to synthetic insecticides, medicinal plants have been in recent years in search of compoun

48. Response of Tahiti lime fruits (Citrus latifólia Tan.) to different percentages of wet area / Resposta da lima ácida Tahiti(Citrus latifolia Tan.) a diferentes porcentagens de área molhada
A irrigação na citricultura ganhou grande importância nos últimos oito anos, devido à utilização de porta-enxertos menos tolerantes a seca. Hoje grande parte da citricultura irrigada é feita por gotejamento, sistema em que apenas uma porcentagem do sistema radicular recebe água. Esses pontos tornam de grande valia estudos relacionados às respostas
