Análise comparativa dos surtos e danos causados pelos besouros desfolhadores Costalimaita ferruginea (Fabricius, 1801) e Costalimaita lurida (Lefévre, 1891) (Coleoptera: Chrysomelidae) em plantios de eucalipto

Os besouros desfolhadores Costalimaita ferruginea (Fabricius, 1801) e Costalimaita lurida (Lefévre, 1891) (Coleoptera: Chrysomelidae) são pragas importantes da cultura do eucalipto. A biologia e comportamento daninho de C. ferruginea já foram caracterizados. Todavia, não existem estudos sobre o potencial de C. lurida como praga da cultura. Assim, o objetivo deste trabalho foi avaliar, de forma comparativa, os surtos e as injúrias causadas por C. ferruginea e C. lurida em plantios de eucalipto. Para isso, 202,8 mil ha de plantios clonais de eucalipto, nos Estados do Espírito Santo, da Bahia e de Minas Gerais, foram monitorados no período crítico de ocorrência (quente e chuvoso). Os surtos detectados foram caracterizados, determinando-se, por meio de amostragens, a incidência, a severidade e as populações absoluta e relativa do inseto por planta atacada. De forma geral, o comportamento daninho de C. lurida foi similar ao de C. ferruginea, em termos de época de ocorrência e tipo de injúrias causadas. Todavia, C. lurida apresentou maiores picos populacionais, em termos absolutos (insetos por planta) e relativos (razão entre o número de insetos e altura das plantas atacadas), e atingiu maior proporção de área, podendo ser considerado mais daninho que C. ferruginea. O besouro C. lurida deve ser monitorado considerando os mesmos critérios. Além disso, os surtos desta nova praga poderão ser avaliados quanto ao nível crítico para controle, empregando-se as mesmas premissas adotadas para C. ferruginea. Adicionalmente aos resultados, registrou-se, pela primeira vez, a ocorrência de C. lurida no Estado da Bahia, em plantas de araçá (Psidium guineense, Swartz) (Myrtaceae).

Estimation of transpiration of the 'Valencia' orange young plant using thermal dissipation probe method

Most studies on measures of transpiration of plants, especially woody fruit, relies on methods of heat supply in the trunk. This study aimed to calibrate the Thermal Dissipation Probe Method (TDP) to estimate the transpiration, study the effects of natural thermal gradients and determine the relation between outside diameter and area of xylem in 'Valencia' orange young plants. TDP were installed in 40 orange plants of 15 months old, planted in boxes of 500 L, in a greenhouse. It was tested the correction of the natural thermal differences (DTN) for the estimation based on two unheated probes. The area of the conductive section was related to the outside diameter of the stem by means of polynomial regression. The equation for estimation of sap flow was calibrated having as standard lysimeter measures of a representative plant. The angular coefficient of the equation for estimating sap flow was adjusted by minimizing the absolute deviation between the sap flow and daily transpiration measured by lysimeter. Based on these results, it was concluded that the method of TDP, adjusting the original calibration and correction of the DTN, was effective in transpiration assessment.

Lectin histochemical aspects of the ovarian lamellae epithelium of Genypterus blacodes (Schneider, 1801)

The composition and distribution of the glycoconjugates (GCs) secreted by the epithelium of ovarian lamellae with reference to the reproductive biology of Genypterus blacodes (Schneider, 1801) through lectin hi stochemistry is here discussed. In this species, the epithelial cells that line the ovarian cavity presented sharp morphological variations along the reproductive cycle related to the mucus secretion that accompanies oocyte ma turation. During sp awning season, residues of mannose and N-acetylglucosamine were detected in the glycocalyx of those cells using lectinhistochemistry. N- acetylgalactosamine and fucose were also observed in the same zone. The greatest variations in the lectinhistochemical pattern were found in the apical cytoplasm composition in comparison to the basal zone of the cells. The results of the present study were discussed by comparing their possible functional implications.

Quality of 'Delta Valencia' orange grown in semiarid climate and stored under refrigeration after coating with wax

The effects of carnauba-based wax on the quality of 'Delta Valencia' orange produced in Ceará state, Brazil, were studied. The fruits were coated with carnauba-based wax and refrigerated (7 ± 2 ºC and 85 ± 2% R.H.) for 28 days. The quality attribute parameters assessed were weight loss, peel color (brightness, hue angle, and chromaticity), peel moisture, pH, soluble solids (SS), titratable acidity (TA), SS/TA ratio, ascorbic acid, total soluble sugars, reducing sugars, yellow flavonoids, and polyphenols. The results showed that 'Delta Valencia' oranges grown in the dry climate of Ceará state has excellent quality. The coated fruits lost mass at a lower rate than the the control fruits. No significant loss of soluble solids, titratable acidity, pH, and SS/TA ratio was observed, while ascorbic acid, soluble sugars, reducing sugars, yellow flavonoids, and polyphenols increased during storage in both the coated and control fruits. Carnauba-based wax coated fruits showed no signal of dehydration keeping their shiny green peel up to the end of the storage. The use of coating was crucial for the maintenance of visual quality by reducing mass loss, as well as keeping peel moisture.

Effects of gutting process on the shelf life of cultured meagre (Argyrosomus regius ASSO, 1801) stored at 4 ± 1 °C

Abstract The aim of this study was to determine chemical, nutritional and microbiological evaluation of whole or gutted meagre stored at 4 ± 1 oC. Whole ungutted (Group A), eviscerated (Group B), beheaded-eviscerated fish (Group C) and fillets (Group D) groups were created for this study. According to fatty acid analysis, it was determined that meagre is rich in PUFA content and the n3/n6 ratio is within the ideal limits. In all 4 groups, obtained from fillets values were the highest in general, quality parameters were found within acceptable limits. Psychrophilic and mesophilic aerobic bacteria counts exceeded the standards for fillet groups on 7th days of storage. According to microbiological analysis, ungutted, beheaded, eviscerated samples were not exceeded limit values on 9th day. In conclusion, whole or gutted (headed and eviscerated) storage of meagre is found to be more advantageous compared to fillets for storage at 4 ± 1 oC.
