It was studied vegetal remainders into four mountain areas: Serra de Bodopitá (Area1), Serra de Bodocongó (Area 2), Serra do Monte (Area 3) and Serra do Canoió (Area 4) located in paraiban Cariri. The study aimed at determines the phytossociolical parameters and for this was used the program Mata Nativa 2. It was also calculated the indexes of Shannon, Pielou equability, diversity of species and families. From the 2972 sampled individuals, 633 belonged to Area 1, 602 to Area 2, 908 to Area 3 and 829 to Area 4. All of them were distributed in 54 species belonged to 25 botanic families. It was observed that the families Fabaceae and Euphorbiaceae had the largest number of species and individuals and after them Cactaceae, Anacardiaceae and Apocynaceae. The Shannon indexes values in Areas 1, 2, 3 and 4 were respectively 2.65; 2.93; 2.35 e 2.59 nats.esp.-1 . The founded densities were 3165 individuals.ha-1 in Area 1, 3010 individuals.ha-1 in Area 2, 4540 individuals.ha-1 in Area 3 and 4145 individuals.ha-1 in Area 4. The four areas had the same species with the most importance values being them: Caesalpinia pyramidalis, Aspidosperma pyrifolium, Bauhinia cheilantha, Piptadenia stipulacea.

This study aimed to provide options of cerrado fruitful tree for neighborhoods to the outskirts of Goiânia, Brazil building up the level of satisfaction of the residents in relation to current local urban landscaping. The choice has been to work with fruit due to the large number of these species in the cerrado needing to preserve the existing genetic variability and protect the local flora. Data was collected through 100 questionnaires, from simple random sampling. It was observed that 53% of respondents were classified as partially satisfied with the landscaping where live, 27% dissatisfied, 10% satisfied, 7% and 3% very satisfied totally dissatisfied. Most people never planted fruit tree, however, 87% would like fruit were planted, indicating that the absence or disability of urban arborization is not a result of predation or popular unrest. It was found that 87%do not have allergies to plants, 8% said they do not know and 5% have allergies, and interesting to give preference to trees with restricted flowering period of a few months. It was found that 93% prefer shaded street, thus, it is suggested the use of species with bulky crown and removed from public lighting. It was observed that 68% did not know or had access to proper pruning procedure to be adopted. The species most appropriate are Centrolobium tomentosum, Cassia ferruginea, Pouteria ramiflora, Dimorphandra mollis, Pseudobombax longiflorum, Inga Alba, Curatella American, Hancornia sXXXpeciosa, Alibertia edulis, Erythrina speciosa, Kielmeyera coriácea, Caryocar brasiliense, Minosa laticífera and Bowdichia vigilioides.

Biological control using natural enemies has become one of the main alternatives to chemical control. Among these enemies, worth highlighting the green lacewings, known for their predatory efficiency and the ability of their larvae to seek out food. The present review aimed to gather scientific knowledge about these predators, intending to encourage the inclusion of theses insects in future biological control programs.

The study aimed to evaluate the effect of two doses of organic material in the nutrition of tomato (Lycopersicon esculentum), cv Santa Cruz, grown in pots in an Oxisol Ultisol Distrocoeso the municipality of Rio Largo - AL. The design was in randomized blocks in factorial 2 X 4 (two and four fertilizer doses) with 5 replicates. The experimental unit consisted of a vessel with capacity for 12 dm3 containing 15 kg of soil. The fertilizer materials were: 1 fertilizer - manure from corral + chicken manure + fertilizer and the filter cake of 2 - to corral manure + chicken manure + sugar cane bagasse, in doses 0, 5, 10 and 15 t ha-1. The applications were split in the following way: 10% at the time of transplantation, and 15% at 20, 34, 48, 62, 76 and 90 days after transplanting (DAT) in coverage. The seedlings were produced in the tomato seed, on March 10, 2008, in polystyrene trays with 128 cells, after transplantation and were selected for the vessel on April 02, 2008, leaving two plants per pot . The plants were conducted in mentoring and single stem, and where, therefore, all cultural and treatment plant. There was a collection of leaves 4 + from the apex of the plant, to assess nutritional status at the beginning of flowering. Among the nutrients, the nitrogen was absorbed the most, followed by: potassium, calcium, sulfur, magnesium and phosphorus, whereas among the micronutrients, in increasing order of absorption was the following: boron, zinc, copper, manganese and iron. According to analysis of variance and regression analysis of the fertilizer did not affect the levels of nutrients in the plant, with only difference between the doses.

The objective of this research was to know the species and the population fluctuation of fruit flies (Diptera: Tephritidae) in a commercial mango (Mangifera indica L.) orchard in the coast of Ceará State. The study was developed from July of 2005 to July of 2007, in the municipality of Beberibe (CE). The capture of the fruit flies was performed using McPhail traps with 5% corn protein hydrolyzed solution as attractant. Weekly, the captured insects were sorted, the fruit flies were maintained in 70% alcohol solution and subsequently identified. The population fluctuation was estimated using the FTD (Fly/Trap/Day) index. During the research, six fruit flies species were captured: Anastrepha obliqua (Macquart) (63%), A. zenildae Zucchi (7%), A. sororcula Zucchi (5%), A. fraterculus (Wied.) (2%), A. distincta Greene (2%) and Ceratitis capitata (Wied.) (21%). The Anastrepha spp. and C. capitata population peaked was between April and July, in both years of study.

The trial was carried out at Santana da Vargem, State of Minas Gerais, Brazil, from September to November 2003, with the objective of evaluating the productivity and nutritional state of lettuce cultivars in function of the Si addition. The experimental design was in randomized blocks with four replicates, in factorial arrengement with additional treatments: 3 x 4 +3, composed by three lettuce cultivars: Raider (group crisphead); Regina (group loosensmooth) and Vera (group loosen crisped) and four Silifértil® rates (0, 1, 2 and 4 t ha-1). The additional treatments were composed by the application of 3.5 t.ha-1 of Limestone for the three cultivars. The nutritional status of lettuce was evaluated by Diagnosis and Integrated Recommendation System. The application of Si in the form of Silifértil® do not increase the yield of the lettuce Rider, Regina and Vera. The fertilization with Silifértil® do not increase the silicon concentration in the aerial part of the lettuce, increase the DRIS indice for Si, but do not change the concentrations of most of the nutrients analyzed, except for the concentration of the K and Zn. The concentration of K decreased in function inverse polinomial, with low point in 1,89 t ha-1 of Silifértil®, and without adjusting, a regression curve, the tenor of Zn, decreased with the increase of the rate of Silifértil®. The fertlization with Silifértil® do not promote one better nutritional status for lettuce crops.

The study was to evaluate the effect of the combination of different irrigation levels and rates of potassium applied drip on parameters indicative of the banana production Pacovan Apodi (var. SH3640). The experimental design was a randomized complete block with split plot and 3 replications. The treatments consisted of a combination of five layers of irrigation and drainage lysimeter by means for four doses of potassium applied by fertirrigation. The variables were the weight of the bunch without stalk, the number of hands in the bunch, the weight of the hand of the central cluster and the number of fruits of the central cluster of the bunch. The data were obtained from the harvest of the first two cycles of the experiment, from March 2006 to September 2007. The treatments with irrigation levels influenced in all tested parameters of production, while the doses of potassium only influenced the weight of the bunch without stalk.
