1. Effects of Oral Oxytetracycline-Therapy on Wound Progression and Healing Following Aeromonas caviae Infection in Nile Tilapia (Oreochromis niloticus L.)
Abstract The effects of oral oxytetracycline (OTC)-therapy against Aeromonas caviae infection as well as the wound progression and healing in intramuscular (IM) and abrasion-immersion (AI) challenged Nile tilapia juveniles were evaluated. The IM challenge caused significantly (p < 0.05) high mortalities (90%) compared to AI challenge (40%). The mortalities r

2. Difference between isolates from brown eye spot and black spot lesions in coffee plants
Resumo: O objetivo deste trabalho foi avaliar a diferença entre isolados de dois tipos de sintomas de cercosporiose do cafeeiro (mancha de olho pardo e cercospora negra) em relação à morfologia conidial, ao crescimento micelial, à produção de cercosporina e à reprodutibilidade dos sintomas em folhas de cafeeiro coletadas em três municípios de Minas

3. COPPER OXYCHLORIDE APPLIED ALONE TO CONTROL CITRUS BLACK SPOT
RESUMO A Mancha Preta dos Citros causada pelo fungo Phyllosticta citricarpa é uma doença que causa lesões em frutos e queda prematura em estágios mais severos. O uso de fungicidas sistêmicos é a principal medida de controle, porém a busca por um controle alternativo pode envolver a aplicação de fungicidas cúpricos isoladamente, em intervalos reduzi

4. Association mapping in common bean revealed regions associated with Anthracnose and Angular Leaf Spot resistance
ABSTRACT: Despite important biotic stresses to common bean, Anthracnose (ANT) and Angular Leaf Spot (ALS) can cause losses of up to 80 % and occur in more than 60 countries around the world. Genetic resistance is the most sustainable strategy to manage these diseases. Thus, we aimed to (1) identify new SNP markers associated with ALS and ANT resistance loci

5. Selection index based on phenotypic and genotypic values predicted by REML/BLUP in Papaya
Resumo A seleção de genótipos superiores com base na resposta simultânea à diferentes caracteres é uma estratégia fundamental no melhoramento de plantas. Neste estudo objetivou-se comparar a eficiência de quatro índices de seleção construídos a partir de valores fenotípicos e genotípicos, em uma população segregante da cultivar Rubi Incaper

6. Susceptibility of Pecan Cultivars to Cladosporium cladosporioides Species Complex
ABSTRACT Recent studies have observed symptoms of leaf spot in pecan (Carya illinoinensis ) associated with species of the Cladosporium cladosporioides complex (C. cladosporioides, C. pseudocladosporioides , and C. subuliforme). Therefore, the present study aimed to investigate the pathogenicity of these Cladosporium spp. isolated from two pecan cultivars.

7. Temporal progress and spatial patterns of quiescent diseases in guava influenced by sanitation practices
ABSTRACT: Postharvest diseases are a major problem in guava crops as the symptoms normally appear during fruit ripening. This study aimed to detect and characterize the temporal dynamics and spatial patterns of the most important guava diseases in orchards with and without removal of crop residues as a sanitation practice. The experiment was conducted in an

8. The impact of eggshell colour and spot area in Japanese quails: II. Slaughter and carcass characteristic
ABSTRACT This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on growth performance and carcass traits of Japanese quail (Coturnix coturnix japonica) eggs. Study material were allocated to five groups according to their eggshell and spot colours: black spots on greyish white coloured

9. The impact of eggshell colour and spot area in Japanese quails: I. eggshell temperature during incubation and hatching results
ABSTRACT This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on eggshell incubation temperature and hatching outcomes of Japanese quail eggs (Coturnix coturnix japonica). Study material was allocated to five groups according to their eggshell and spot colours: black spots on greyish

10. Incidence of postharvest diseases on 'Kumagai' and 'Pedro Sato' guavas at wholesale markets in Brazil
The time after harvest is characterized by physiological changes in the fruit that favor the occurrence of postharvest diseases, which are often observed only after sale. As a result, the damage resulting from the action of quiescent pathogens can be underestimated. From November to April of the years 2009/2010 and 2010/2011, a survey was conducted to quanti

11. Genetic variation among Phyllosticta strains isolated from citrus in Florida that are pathogenic or nonpathogenic to citrus
Citrus black spot is an emerging disease in Florida since 2010. The causal agent is Phyllosticta citricarpa (teleomorph Guignardia citricarpa), but non-pathogenic P. capitalensis (teleomorph often referred to as G. mangiferae) is often isolated from black spot lesions. Florida isolates of P. citricarpa and P. capitalensis from citrus have not been characteri

12. Uma nova espécie de Orthoderella Giglio-Tos (Mantodea, Mantidae, Photinainae) do Brasil
A new species of Orthoderella Giglio-Tos (Mantodea, Mantidae, Photinainae) from Brazil. The Neotropical genus Orthoderella Giglio-Tos includes four species recorded in Argentina, Bolivia, Uruguay, and from central western, southern, and southeastern Brazil. Orthoderella caatingaensis sp. nov., from the Caatinga biome in northeastern Brazil, is described here
