Survey of sucking insects from citrus orchards by using a costal suction trapThis paper deals with a survey on sucking insects of the 0rders Homopt e ra and Hemipter a from a citrus orchard by usingacos tal coll ector trap in the munic ipality of Limeira, State of São Pau lo, Brazil. A fauna! study was developed in o rder to detect thepre dominant species, whic h cou ld be related to the citrus decline pro b lem. The ma in species collected were Scaphytopius Zineatus (Hom.--;-Cicadel lidae) a nd Leptocory za tipuZoides (Hem. , Alydidae) .Recebido em 14 /03/83.

The cagaita is a native fruit of the cerrado, of high perishability, and for postharvest conservation of the fresh fruit, methods are used to increase its life cycle. In the present study, edible coatings are used, a technique that aims to control the loss of mass through transpiration reduces gas exchange, increases the shelf-life, improves the appearance, preserves the structural integrity and mechanical properties. The study aims to evaluate the influence of coatings based on biopolymers on the maturation of cagaita during storage. The factorial scheme 3 x 4 was used, with three treatments - without coating, polysaccharide coating and protein coating, four evaluation points - with an interval of 2 days, stored at 25 ºC. The fruits were submitted to weight loss, pH, titratable acidity, soluble solids, and ascorbic acid evaluations. There was no influence of the time factor in the present study, and for titratable acidity, ascorbic acid, soluble solids, and pH, there was no significant difference between treatments. Observing the content of soluble solids, the main indicator of ripeness, which varies from 5 to 7 ºBrix, it was concluded that the fruits did not ripen.

The objective of this work was to evaluate the shelf life of purple curly and crisp lettuce varieties in two different harvesting periods with different borehole, no bore and no packaging, evaluating soluble solids content, titratable acidity and mass loss. All parameters were statistically significant, but the most important was the loss of mass, indicating that the treatments with the use of the package without bore harvested at 5:30 proved to be the most effective in the conservation of lettuce during the epochs.
