| Citric fruits - in natura, as frozen pulp or even as juice - are one of the most important Brazilian exportation products. They are a source of ascorbic acid - a potent antioxidant, and pectin, which is used in the food industry and is an important dietary fiber. This project aims to quantify ascorbic acid and pectin contents in citric fruits, commercial oranges and tangerines, comparing them in sizes and varieties. Ascorbic acid amount was measured in juice comparing sizes, varieties and storage conditions, using a tritimetric method with 2.6-dichlorobenzenoindophenol indicator. Total and soluble pectin in each part of the fruits (peel, albedo, pulp and juice) were quantified using the polygalacturonic acid as a standard. Differences were found between... |

| Alternaria brown spot, or ABS (Alternaria alternata), is the most prevalent fungal disease of tangerines in the world. Field observations have revealed ABS lesions on leaves wounded by the citrus leaf miner (CLM). Thus, the objective of this study was to assess the relationship between CLM and ABS. Leaves from young Murcott tangor plants and detached leaves from 16 different varieties of tangerines with and without lesions caused by CLM were inoculated with A. alternata. The symptoms of the plants were subsequently quantified by counting the number of lesions, and the lesion area was estimated using a diagrammatic scale. The presence of CLM damage aggravates the severity of Alternaria alternata fungus infections in susceptible tangerine varieties. |

| This paper presents a faunistic analysis of the frugivorous species of Tephritoidea (Diptera) captured in three citrus groves in the municipalities of Anastácio (Chácara Laranjal, 20º 31' 36'' S, 55º 50' 12'' W, 170 m) and Terenos (Chácara Suzuki, 20º 26' 12" S, 55º 04' 54'' W, 308m), MS, Brazil, during a 25 month period. McPhail traps with 5% hydrolyzed corn protein were hung in Citrus sinensis (L.) and C. reticulata (L.) trees, spaced 30 m apart. The Tephritidae species caught were: Anastrepha alveatoides Blanchard, A. bezzii Lima, A. castanea Norrbom, A. daciformis Bezzi, A. dissimilis Stone, A. distincta Greene, A. fraterculus (Wied.), A. grandis (Macquart), A. haywardi Blanchard, A. leptozona Hendel, A. macrura Hendel, A. montei Lima, A. obliqua... |
