“…After harvesting, diseases can take place through direct access by natural openings (ostiole and peduncle) or mechanical damage (injuries) arising from handling (DURIGAN, 1999). During a survey carried out in the state of Paraná Botrytis cinerea was cited for causing symptoms in postharvest figs (VELLOZO et al, 2001). Throughout the world genus Botrytis that causes gray mold disease and was reported in several plants in both pre and post-harvest (TOFOLI et al, 2011).…”

“…Fruit flies are the main pests of orchards (Zucchi, 2000 a, b); however, occurrence records of this pest in the MRC are scarce. The occurrence of fruit flies in this region was initially registered in the 1940s by Vellozo et al (2001), with the identification of Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) in peach orchards in Curitiba, and Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in citrus orchards in Cerro Azul. Fehn (1981) identified C. capitata, A. fraterculus, A. grandis (Macquart), A. pseudoparallela (Loew), and A. serpentina (Wiedemann) (Diptera: Tephritidae) in peach orchards located in four municipalities of the MRC.…”

The objective of this trial was to characterize the assemblage structure of fruit flies (Diptera: Tephritidae) by determining the diversity and faunal indices. Fruit flies were collected for ten years between 2003 and 2015 in six municipalities of the Metropolitan Region of Curitiba, Paraná. The orchards were divided into three crop protection strategies: organic, conventional, and integrated pest management. The characteristic of each community was determined using the Shannon-Wiener, Margalef, and Pielou's indexes. The frequency, constancy, and dominance indexes were also determined. Biological material was analyzed using the explanatory variables: site, crop, plant protection strategy, and susceptibility period. A total of 8,089 fruit flies were collected, of which 4,681 were females. The species Anastrepha daciformis Bezzi, A. dissimilis Stone, A. distincta Greene and A. pickeli Lima were recorded for the first time in Paraná State, the occurrence of three other species was recorded for the first time in the Metropolitan Region of Curitiba (A. montei Lima, A. obliqua Macquart, and A. sororcula Zucchi), in addition A. fraterculus (Wiedemann), A. grandis (Macquart) and Ceratitis capitata (Wiedemann). A. fraterculus accounted for 98.5% of the collected species. Only A. fraterculus and A. sororcula were found in fruits. Fruit flies occurred predominantly in peach trees cultivated under organic conditions. The Shannon index indicated that the municipality of Cerro Azul had the highest diversity and richness whereas apple orchards had the lowest diversity. Crops cultivated under organic conditions exhibited the highest diversity whereas those cultivated under conventional conditions had the highest evenness index. The largest specimens number was collected during the period of crop susceptibility.

“…Puccinia psidii is a biotrophic fungus (Basidiomycota, Pucciniales) native from South America and the Caribbean region, with its wide natural geographical distribution including Brazil (Grillo, ; Jackson, ; Pickel, ; Thurston, ; Vellozo, Nowacki, & Vernalha, ; Winter, ), Uruguay (Spegazzini, ), Puerto Rico (Arthur, ), Paraguay (Spegazzini, ), Ecuador (Stevenson, ), Colombia (Kern & Chardón, ), Dominican Republic (Kern, ), Venezuela (Chardon & Toro, ), Argentina (Di Fonzo, ), Jamaica (Smith, ), Barbados and Windward Islands (Baker & Dale, ), and Trinidad and Tobago (Baker & Dale, ). In addition, this disease has been reported in many parts of the world such as the United States (Marlatt & Kimbrough, ; Mellano, ; Rayachhetry, Elliot, & Van, ; Uchida, Zhong, & Killgore, ; Zambino & Nolan, ), Mexico (Gallegos & Cummins, ), Japan (Kawanishi et al., ), Australia (Carnegie et al., ), China (Zhuang & Wei, ), South Africa (Roux, Greyling, Coutinho, Verleur, & Wingfield, ), New Caledonia (Giblin, ), Colombia (Rodas et al., ) and Indonesia (McTaggart et al., ).…”

Climatic favourability zones for Eucalyptus rust in Brazil

et al. 2016

Brazilian forest-based industries are supported by more than 5.5 million hectares of Eucalyptus growing under different climatic conditions with different degrees of favourability for rust Puccinia psidii, including both traditional and expanding areas, where such disease is of major concern for the industry, foresters and scientists. The main objective of this study was to define favourable climatic zones for Eucalyptus rust in Brazil with the following aims: (i) to develop a spatial method for estimating the mean night-time temperature (T ng ); (ii) to assess and validate a Eucalyptus rust model;and (iii) to map Eucalyptus rust favourability zones in Brazil based on the proposed model. A straightforward method, based only on latitude, day of the year, maximum and minimum air temperatures, was developed to estimate T ng , which is a key variable for a proper application of Ruiz rust model. Based on 37 field experiments with natural rust occurrence, it was observed that climatic conditions are determining factors for disease severity. Significant correlations between disease severity observed in the field and climatic conditions were found: a negative correlation with temperature (r = .50, p < .01) and a positive correlation with relative humidity (r = .89, p < .0001). A significant correlation (r = .81, p < .0001) between the normalized infection index, produced from Ruiz model, and the average rust score was also observed. Once the model was validated under field conditions, it was applied using historical average data of air temperature and leaf wetness duration to obtain monthly Eucalyptus rust favourability maps for the whole country. These final maps show that favourable climatic zones for Eucalyptus rust are extremely dynamic, with high temporal and spatial variability in Brazil and that climatic conditions should be considered for expansion of Eucalyptus to new areas, in breeding programmes, and for defining the most suitable seasons for forest establishment in each climate of the country. These results provide forestry managers with practical tools to reduce uncertainty about the expected severity of Eucalyptus rust in Brazil.
