The search for healthy foods associate with health and quality of life has contributed to increase the fish consumption. The aim of this study was to verify the profile of fish consumption by the customers of the UFERSA restaurant. 135 questionnaires were applied to meet the consumer of fish, frequency, forms of use and receptivity to new products made of fish. The results indicated low fish consumption by the customers assigned to low supply, lack of habit and high price compared to other meats. The respondents were receptive to new products unless the price is competitive. Research and development of new products based on fish are needed combined with the marketing showing benefits of fish consumption to health.

The viruses from the genus Begomovirus, family Geminiviridae are considered emergent pathogens, mainly because of the population explosion of their insect vectors. For this reason, more attention needs to be directed to the correct virus species identification inside the genus. The present paper had the objectives of serologically detecting a begomovirus in Macroptilium lathyroides plants in the State of Ceará, and developing biological, serological and molecular studies with a virus isolate obtained from M. lathyroides. Indirect ELISA with antiserum for Macroptilium golden mosaic virus (MaGMV) demonstrated that the samples collected from M. lathyroides showing golden mosaic in the field were infected with a begomovirus. The virus isolate obtained was transmitted by grafting to eight species of the family Leguminosae, four species of Solonaceae, and one species in the family Amaranthaceae. The virus also was transmitted from M. lathyroides to M. lathyroides by the whitefly Bemisia tabaci biotype B. A DNA fragment of 1.2 kb was obtained by PCR with the primers PAL1v 1978 and PAR1c 496 for component A, and a DNA fragment of 0.5 kb was obtained with the primers PBL1v 2040 and PCR cl for component B, confirming the presence of a begomovirus infecting M. lathyroides. Molecular studies indicated that the begomovirus isolate showed 77% genomic similarity with Bean golden mosaic virus and 75% with Cowpea golden mosaic virus for their cp and rep genes, indicating the possibility that the isolate is a distinct virus species of the Begomovirus genus.

The aim of the present paper was to evaluate the Jathropa curcas L response to different doses of nitrogen, water regimes and soil surface nature. The experiment was conducted from May 2009 to February 2010 under greenhouse conditions at the Sustainable Development Center of the Federal University of Paraiba in Sumé-PB. A factorial experiment in blocks was used with four organic fertilizer (0, 50, 100 and 150 kg of N/ ha), four irrigation levels (50, 75, 100 and 125% the Class A pan evaporation) and four additional treatments with soil mulching. Sixty plastic vases 100 l capacity were used to cultivate the plants during 257 days and a Class A Evaporation Pan was installed in the greenhouse to monitor daily water evaporation. The plant variables evaluated were plant height, stem diameter, leaf area, total aerial and root dry mass. The increase of the soil water content and soil mulching had significant effect on the evaluated plant variables.

The timbó (Magonia pubescens St. Hil.), tree typical of the cerrado, has medicinal, timber, craft, ornamental and larvicidal. The aim of this paper to evaluate seedling emergence of M. pubescens under different light conditions. The experiment was conducted in chambers B.O.D. temperature 30 °C, substrate sand, in a completely randomized design with five treatments and four replications of 50 seeds. The treatments were: 1) a photoperiod of 24 hours, 2) absence of light, 3) a photoperiod of 12 hours, 4) a photoperiod of 8 hours and 5) a photoperiod of 16 hours. The smallest percentage and emergence rate (45% and 14 days) were provided 12 h light and 12 h dark, and the emergence in all treatments was high (90 to 97.5%) and emergency speed too (7.4 to 10.5 days). The seeds of M. pubescens photoblastic are neutral in laboratory conditions at a temperature of 30 ºC and the emergence occurs between four and nine days.

In the reclamation of a degraded area, it is important the use of nitrogen fixing legumes, associated with climax species, to make possible a faster recovery of the environment. In urban centers various wastes are produced, among them the marble rock waste, which, despite having agricultural value, ends up being thrown in the environment.. The objective of this work was to evaluate the Cedrela fissilis growth and of pioneering legume in quincunx system, in degraded area, fertilized with doses of marble rock waste. The treatments, distributed in factorial scheme 2 x 4, in the randomized block design, with three replicates, were: two species of pioneering legume (Acacia mangium and Acacia auriculiformis in quincunx system with the Cedrela fissilis) and four doses of marble rock waste (0; 300; 600 and 900 g.cova-1). Were determined annually, along three years, the height of the plants, the stem diameter, the cup diameter and, in the end, the mortality percentage. The Acacia auriculiformis presented characteristic of better growth than the Acacia mangium and greater resistance to adverse conditions of degraded soil. There was tendency of reduction of the characteristics of growth of the Cedrela fissilis and of the Acacias with the increment of the doses of rock powder applied to the soil. The Cedrela fissilis presented, in general, larger growth, when combined with Acacia mangium than with Acacia auriculiformis, however, showed a high mortality after two years of planting.

The growth retardants Paclobutrazol (PBZ) and Cycocel (CCC) had been used, in spraying, associates or not with two cytokinins: Benziladenina (BAP) and Thidiazuron (TDZ), and a nitrogenous base, the Uracil, with the purpose of studying its effect in the bud fertility of the 'Superior Seedless', grafted on the 'Harmony' and IAC-766 'Campinas', and of the 'Crimson Seedless' and 'Thompson Seedless', grafted on the 'Harmony', in the conditions of the São Francisco Valley, Brazil. It was observed that the separately use of the products had not promoted significant differences in the studied of the bud fertility, but, the association of the growth retardants with the TDZ it induce the 'Thompson Seedless' to a bigger productivity, and that the expression of the bud fertility of the 'Seedless Superior' benefits on to being grafted on the 'Harmony' rootstock.

To study plant growth and yield of cauliflower, two field trials were carried out: the first springsummer (Oct. 07, 2006 to Jan. 28, 2007) and the second autumn-winter (Apr. 04, 2007 to Jul. 09, 2007). The experimental design was randomized complete blocks in 4 x 4 factorial design with three replications. The following factors: line spacing (0.6, 0.8, 1.0 and 1.2 m) and plant spacing (0.4, 0.5, 0.6 and 0.7 m). The used cultivar was cv. Verona 284. The characteristics, number of leaves by plant, diameter of stem, diameter of inflorescence, inflorescence mass and yield were evaluated. With the reduction in spacing, were observed lower numbers of leaves, stem diameter, diameter and mass of the inflorescence, but there was an increase in yield. The maximum yield (23 t ha-1) was obtained with 0.6 x 0.4 m, ie, in higher plant population (41,667, plants ha-1).

The lacewings appear in many agroecosystems, preying several species of agricultural pests. They have great search capability, high voracity, high reproductive potential and are easily maintained in laboratory conditions. In laboratory rearing, to avoid problems in the mass production are recommended adjustments in the type and quality of prey to be used in order to obtain individuals with desirable characteristics. It is necessary special care with the laboratory populations, avoiding problems from inbreeding. Larvae were reared individually in Petri dishes (9.0 cm diameter) and fed with eggs of Sitotroga cerealella (Olivier, 1789) (Lepidoptera: Gelechiidae), in the amount of 25 mg / larva, while the adults were kept in PVC cylindrical cages (10 cm x 30 cm). Thus, the study analyzed the influence of the size of the population of Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) on the pre-imaginal period (egg to adult) and reproductive capacity of this specie come from different populations and generations of laboratory. To this end, we used two populations, one of Jaboticabal (F8 and F21) and one of Piracicaba (F6 and F15), and subpopulations of 1, 5, 10, 15 and 20 couples, analyzing the incubation of eggs and the number of eggs per female in each population, generation and subpopulation. The pre-imaginal period (egg to adult) and the number of eggs per female of C. externa are influenced by the generation and the number of founding individuals, being these parameters favored when laboratory populations are established with the largest number of couples.

The riparian forests, belonging to the permanent preservation areas, are of fundamental importance for the preservation of water quality and minimize the effects of erosion on soil and thus the sedimentation of river. The land use of these areas cause environmental risks, especially to water resources. The geospatial technologies are, in the current scenario, as a tool that shows the real situation of the area, identifying the critical points, thus contributing to better management of these areas. Therefore, this study aimed to establish a spatial study of APP of the Mossoró river in urban area of municipal district of Mossoró, in the state of Rio Grande do Norte, identifying the main causes of degradation and it's consequences to environment, especially the water resource, through geoprocessing's techniques. Geographic Information System (GIS) were used to spatially delimitate the area and image processing. Deforested areas comprised 310 ha, being more concentrated among the East-West Bridge and Barrocas's dam. Edification areas were more concentrated in Santa Luzia's Island and between Castelo Branco and Jerônimo Rosado's Bridges, occupying 78 ha. The areas covered by vegetation comprised 70 ha, which more concentrated in the area of Genesio' dam. There was enough sources of water pollution, especially domestic sewage.

The shortage of animal feed during the dry season has led to the development of food handling techniques that are efficient and sustainable for farmers and ranchers. The research aimed to evaluate the chemical composition, voluntary intake and digestibility of faveleira (Cnidoscolus phyllacanthus (Muell. Arg.) Pax et K. Hoffman), to supply the sheep provided as in the form of hay. Five castrated 18 months old sheeps with a mean age of 18 months old with and initial average weight of 31.75 kg ± 1.08 were evaluated, using the conventional method of total collection of feces. The hay was made naturally in sunny area, the forage being harvested in areas of caatinga at the IPA¿s Sertânia Experimental Station belonging to the Agronomic Institute of Pernambuco/IPA. The faveleira hay results of chemical analysis percentages were: 92.95 dry matter (DM); 89.28 organic matter (OM); 13.48 crude protein (CP); 3.52 ether extract (EE); 41.42 does not extract nitrogen (NEN); 41.92 neutral detergent fiber (NDF); 26.71 acid detergent fiber (ADF) and 30.36 non-fiber carbohydrates (NFC). The voluntary intake of DM, CP, TDN, NDF, ADF and NFC, expressed in g kg-1 PV0, 75 were (93.14, 12.52, 56.06, 39.04; 24.88 and 28.28), respectively. The digestibility percentages were: 63.66 (MS); 66.06 (MO); 74.52 (PB); 36.44 (EE); 74.32 (ENN); 57.32 (NDF); 54.77 (FDA) and 56.91 (NFC). These results show that the faveleira hay could be a viable alternative to dietary supplementation of sheep during the dry season to semiarid of Brazil.
