Mimosa caesalpiniaefolia Benth., (Mimosaceae) it´s a Northeast native species from Brazil and cause its multiple utilities, it has been intensively used. Is conventionally propagated through seeds, but this process isn't easy and plant with a wide range of genetic variability. For this reason, the micropropagation assumes importance. Two experiments had been lead, being that in the first, different combination of 2,4-dichlorophenoxyacetic acid (2,4-D) and benzilaminopurine (BAP) were evaluated and in the second, two ways of culture. In the first experiment the explants had been gotter from three years old plants and inoculated with MS medium (Murashige & Skoog, 1962) substance in different concentrations of 2,4-D and BAP. The observed variables were number of shoots for explants, number sprouted explants and percentile of contamination. In the second experiment explants from sprouted in vitro plantlets inoculated with a complementary formularization substances called MC1 (25 mL of medium with next composition: 20% water coconut (v/v), myo-inositol (0,1 g.L-1), ascorbic acid (0,09g.L-1)) and MC2 (20% water coconut (v/v), myo-inositol (0,1 g.L-1), ascorbic acid (0,1 g.L-1), (0,0155 g.L-1), tiamin (0,02 g.L-1), boron (0,0015 g.L-1), extract of malt (0,3 g.L-1)), both solidificed with agar (7g.L-1). In these experiments the observed variables were number of shoots per treatment and number of callus per treatment. In the combination of 2,4-D and BAP, none morphogenetic reply in the inoculeted tissues was identified. The substances MC1 and MC2 had induced in average callus sprouted in 85,8% of the inoculeted explants. In the first experiment, 34% were infested by fungus.

Due the necessity to look for alternatives to produce larger amount of quality foods, as well as to develop research that seeks viable solutions for use of waters of the low quality, this work was addressed. The objective was to know the behavior of red earthworm of California when watered with waters of different from salinity for 45 days. The experiment was installed in the earthworm house of UFERSA. The design used was randomized blocks with four treatments and six repetitions. The used treatments were watering waters with four levels of electric conductivities (T1 = 0.5 dS m-1 T2 = 5.0 dS m-1 T3 = 10.0 dS m-1 T4 = 15.0 dS m-1, being T1 originating from local well and the others obtained by the increment of chloride of sodium (NaCl) to the water used in T1. The 24 portions were composed by concrete pitchers containing 1.5 liters of tanned manure and 6 young earthworms of uniform size. The Mass of Head offices Final Average and the Relative Mass of Head offices they didn't suffer significant decrease when the salinity of the watering water increased from 0.5 to 5.0 dS m-1. The watering of earthworms with waters of electric conductivity of up to 5.0 dS m-1 didn't cause any mortality of head offices. The reduction of the Mass of the Final Population went of 1.69 g to each dS m-1 increased in the electric conductivity of the watering water. The Relative Population Growth of earthworms decreased 6,6 times when the electric conductivity of the water increased from 0,5 to 5,0 dS m-1.

The citrus leafminer Phyllocnistis citrella Stainton is an important pest of citrus orchards either by direct damage or by favoring citrus canker contamination. The experiment was carried out inlaboratory conditions to evaluate Chrysoperla externa (Hagen) larvae preying on P. citrella egg, larval and pupalstages. It was observed that all the immature stages were preyed by first, second and third larval instars. The developmental time of the predator had direct influence on preying capacity, reaching 100% for predator larvae on the prey second instar larvae. This is the first record of C. externa preying the citrus leaf miner eggs, larvae and pupae in the world.

An experiment was carried out at Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró - RN, for screening the effect of substrate for germination of seeds and seedling growth of Moringa oleifera Lam. It was utilized a completely randomized design with four treatments (substrates: T1= 75% sand + 25% bovine manure, T2= 100% washed sand, T3= 75% sand + 25% worm castings and T4= 75% sand + 25% sawdust) and four replications of 25 seeds. The seeds were sown in the substrates contained in wooden boxes (7,5 cm long x 23,5 cm wide x 39 cm deep). Each box was filled with approximately 6 kg of substrate. The substrates were irrigated once a day (until the tenth day), then twice a day until the end experiment (19 th day). Seedling height, root length, number of leaves, whole seedling fresh and dry matter weights, germination velocity index and germination percent were evaluated. It was concluded that the mix 75% sand + 25% worm castings was the most suitable for the initial growth of moringa and the substrate containing 100% sand provided the best germination index for this species.

In aim to evaluate the nutritional value of shrimp meal its proximate chemical analyzed and a metabolism trial were done. The analyses performed on shrimp meal were dry mater (DM), ash, crude protein (CP), ether extract (EE), crude fiber (CF), gross energy (GE), calcium (Ca), and phosphorous (P). In the digestibility trial sixty broilers with fourteen days old were allocated in a completely randomized experimental design composed by three treatments, four replicates and five broilers per experimental unit. Treatments were a reference standard diet and two trial diets with 30 or 40% of substitution on the reference standard diet. Shrimp meal analyses resulted in 91.81 % DM, 16.31 % ASH, 66.01 % CP, 17.31 % EE, 9.38 % CF, 4726.51 kcal/kg GE, 4.70 % calcium and 1.44 % phosphorus in dry matter. Digestibility coefficient of DM from diets and shrimp meal does not differ but values for EE digestibility differed. In the levels of 30 and 40 % inclusion the mean calculated values of Apparent Metabolizable Energy (AME) for shrimp meal were 3,690 and 3,800, for AME nitrogen corrected (AMEn) the values were 3,478 and 3,554 kcal/kg, respectively.

The influence of seed position and sowing depth on seedling emergence and growth in Moringa oleifera Lam. in two laboratory experiments at Universidade Federal Rural do Semi-Árido, UFERSA, RN, Brasil. In one experiment, the influence of three sowing depths (2.0, 3.0 and 4.0 cm) were evaluated through percent of emergence, emergence velocity index (EVI), seedling height, and whole seedling dry matter. In the second, it was studied the influence of seed position (apex upward, lateral and apex down) on percent of emergence, EVI, seedling height, root length, and whole seedling fresh and dry matters. Both experiments were completely randomized with four replications of 50 seeds. Sowing at 2.0 cm deep provided higher percent of emergence, IVE and seedling height. Seed position did not affect percent of emergence and seedling dry matter, height and root length, however, when the seeds were sown with the apex upward or lying, seedlings had greater fresh matter and higher EVI.
