With the objective of evaluating the effectiveness, in natura, of the plants: melon of São Caetano (Momordica charantia), purgative potato (Operculina hamiltonii) and pumpkin seeds (Curcubita pepo L) on helmints infections in naturally infected goats, submitted to an original therapeutic protocol, were used 40 goats males, of Moxotó race with age varying of six and twelve months, divided in four groups and distributed in the following way: three corresponding to each treatment and a group control, where placebo was used. The administered doses were from 45g/10kg of corporal weight to the leaves of melon of São Caetano, 4,5g/10kg for crumb of the purgative potato and 19g/10kg for crumb of the pumpkin seed, for three consecutive days. In intervals of 30 days feces parasitological exams were accomplished (Gordon & Whitlock, 1938). After 30 and 60 days of treatment, a mean reduction of 63.06% and 2,70% was observed for melon of São Caetano treaty group, 63,9% and 72,32% for purgative potato treaty group and 87,31% and 24,00% for the pumpkin seed treaty group, respectively.

The study was aimed of evaluating the nutritive value of silages from five corn hybrids (AG 122, AG 9090, AG 5011, Dow 766 and DKB 747). The used five treatment with four replications in a completely randomized design to evaluate pH, ammonia nitrogen (N-NH3), dry matter (DM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral (NDF) and acid detergent fiber (ADF), total carbohydrates (TC) and nonstructural carbohydrates (NSC). The ether extract rates (EE), mineral matter (MM), neutral (NDF) and acid detergent fiber (ADF) and non-structural carbohydrates (NSC) was not affected by corn hybrids. The AG 122, AG 9090 and DOW 766 did not differ significantly with values from pH the 3.42, 3.31 and 3.40, respectively. The AG 122 and DOW 766 showed maximum value of N-NH3 (2.89 mg/100ml). The lower values of N-NH3 was found in the AG 9090 (0.87 mg/100ml) and DKB 747 (1.05 mg/100ml). The DOW 766 and AG 9090 had higher value of MS rates, 33.51 and 32.32 %, respectively. In the silages, the pH and N-NH3 values had demonstrated that five corn hybrids supplying a good fermentation standard, all the corn hybrids can be classified like a good quality for silages.

The search to exotic fruits by the consumers and producers have in creasing in the latest years. The commercialization in CEAGESP is being similar to the flowers, that are an important part. The dovialis can be used in this way and the present research was conduced due the ausence of technical information about this culture. Evaluate the influence of the temperature on percentage of germination of seeds of this plant. The experiment was conduced in the Laboratory of Seeds, located in the Department of Vegetable Production, of FCAV - UNESP - Campus of Jaboticabal/SP, using seeds that were extracted from ripe fruits of dovialis trees, washed, placed to dry on shade and so conditioned in gerbox, being realized 4 replications with 10 seeds in each one and the treatments were composed by 4 temperatures: 15, 20, 25 and 35ºC, in a experimental delineation entirely randomized. The values of percentage of germination were transformed in arc sen x/ 100 . The averages were compared by the test of Tukey, with 5% of probability. Were realized daily evaluations of the number of germinated seeds, being the percentage of germination represented by the adding of the obtained plants, and the VIG was calculated according to Maguire (1962). Through the obtained results in this research, can be concluded that the temperatures of 20 and 25ºC were the most appropriated to a higher and faster germination for the specie in study.

The objective of this paper was to know the species of the leafminer (Diptera: Agromyzidae) associated with melon plant Cucumis melo L., in the Chapada do Apodi, semi-arid region of the Rio Grande do Norte state, and report losses due to leafminer mining. This way, leaves infested with leafminer larvae were collected in the field and carried to laboratory, in order to obtain pupae. These pupae were placed inside glass containers until adults emergence. All identified adults belonged to Liriomyza trifolii (Burgess). In some farms leafminer caused losts that range from 10 to 15% of the whole area, due to low fruit ºbrix value. From pupae also emerged some Opius sp. (Hymenoptera: Braconidae) individuals, a leafminer natural enemy, endoparasites the larva-pupae of L. trifolii.

The objectives of this research were to report Meloidogyne mayaguensis on seedlings of guava (Psidium guajava) cv. "Paluma" in commercial nursery in Assu municipality and in commercial field of pipper (Capsicum annum) cv. "Comandante" in Baraúna municipality, in Rio Grande do Norte State and to notify all of segments involved to commercial growing of fruits and vegetables about the risk that seedlings infected by this pathogen represents to the agro-centers of Rio Grande do Norte and Ceará States. Concerning to both reports the identification of pathogenic species was made by the a-esterasic fenotype characterization. The present reports of M. mayaguensis represent the second and the third ones in Rio Grande do Norte State,having been made the first one on plants of guava in Touros municipality. Meloidogyne mayaguensis can represent a threat to commercial growing of fruits and vegetables if eradication and exclusion methods of control will not beused.

The aim of this work is to approach the prevalence of pathological alterations of the genital system of anestrous females of collared peccaries (Tayassu tajacu). The genital systems of 14 matrices proceeding from the Centro de Multiplicação de Animais Silvestres - CEMAS, of the Universidade Federal Rural do Semi-Árido - UFERSA , that were without activity breeding for a period above of one year had been studied. After it abates of the animals had been collected the agencies that compose the genital system and lead to the Laboratory of Animal Pathology of the Institution for pathological alterations evaluation. The joined pathologys had been hydrosalpinges and ovarian hypoplasia with four cases each (28.6%),one (6.7%) case of persistent corpus luteum associate to mucometra and 2 (14.3%) cases of ovarian cysts. The pathologys of the genital system of collares peccaries can, in changeable way, to compromise temporary or the fertility permanently, diminishing the reproductive effectiveness, with consequent reduction of the breeding, generating economic losses .

This work aimed to evaluate the seeds germination and vigor of cv Golden papaya fruits after seeds and fruits storage. The papaya fruits were picked from two maturation stage, from Caliman Farm, in Linhares - ES. The fruits were conserved in 25ºC for 10 days and the seeds germination was evaluated at the 0, 2, 6 e 10 days. After extraction and washing of the seeds, the drying was accomplished using an oven-dried with air circulation at 30ºC until they reached 8 to 10% humidity. A part of the seeds was analyzed, immediately, as germination and vigor percentage (first count of germination test and percentage of strong seedling in first count of germination). Another part was stored in packings of the type pouch of flexible aluminum by 30 and 120 days in 15ºC. The experimental design used was completely randomized in 4x3 factorial scheme with four replications. The treatments consisted of four fruits storage period (0, 2, 6 e 10 days), with three seeds storage period (0, 30 and 120 days). The vigour was better availed by first count of germination test than by percentage of strong seedling. There were increase in the seed germination and vigor with the increase seed and fruits storage period. The fruit storage for 10 days and seeds storage for 120 days allowed hither seeds germination.

The experiment were carried out to determine sodium requirements for egg-white (EW) and egg-brown (EB) strain pullets from 12 to 18 weeks of age. It was used a completely randomized design according to a 6x2 factorial (sodium levels: 0.04; 0.10; 0.16; 0.21; 0.27 and 0.32%; with 2 strains), content five replicates of six pullets per experimental unit. The standard basal diet was formulated to contain 2,900 kcal AMEn/kg and 14.0 % CP. Feed intake, water intake, daily weight gain, feed: gain ratio, rectal temperature, and comb size were evaluated, as well as feces dry matter and humidity. In the experiment, there was no interaction between sodium levels and strains on the studied variables. The sodium levels had significant effects on feed intake, daily weight gain and feed: gain ratio according to the quadratic model and increased water intake and feces humidity linearly, whereas the feces dry matter and rectal temperature decreased linearly. For EW and EB strain, it is recommended 0.18 % sodium or daily intake of 131 and 148 mg of sodium from 12 to 18 weeks of age.

The objective of evaluating the effect of salinity water irrigation of the for vegetative phase of castor culture, it was developed a greenhouse experiment at Environmental SciencesDepartment of UFERSA. The experimental delineating used was entirely randomized with six treatments and three replications. The soil utilized was eutrofic red-yellow latossol and the treatments were six waters with different salinity levels (0,5; 1,0; 1,5; 2,0; 2,5; 3,0 dS·m-1). The cropping was carried out with the BRS 149-Nordestina variety. The variables evaluated were: chemical-physical characteristics of the soil (pH, electrical conductivity, Ca, Mg e Na), and in the plant, the plant height, stalk diameter, fresh and dry matter. It was observed that the soil under went the influence of the waters utilized: the pH, Electrical Conductivity and changeable Na with the water salinity. With the increase of the salinity, the plant development decreased.

The in vitro propagation can provide the production of uniform plants, with high quality and free of diseases, and allow fast and genetically reliable multiplication of new cultivars and hybrids. In this context, the present work had the aim at developing a protocol for the in vitro propagation of Ananas lucidus Miller. Two experiments have been carried through, the first on the effect of BAP on nodal multiplication, an the second on plantlet acclimatization. For the multiplication it was used a completely randomized factorial design with 10 repetitions, and 2x5 factors, composed by two consistences, solid and liquid, and five BAP dosages (0,0; 1,0; 2,0; 3,0; 4,0) mg L-1. For the acclimatization experiment it was used a randomized blocks design with 5 treatments, 5 repetitions and 5 plants in each experimental unit, it being tested different substrata (coconut fiber, compost of plant residues, vermiculite, coconut fiber + compost, and vermiculite + compost). The number of sprouts (NB) produced in the liquid medium in the 2,0 mg. L-1 BAP dosage treatment was greater than in the 0,0 mg L-1 dosage, at a 5% probability level, and similar to the 1,0; 3,0 e 4,0 mg.L-1 dosages. It was observed that in the liquid media treatments there was a higher proliferation of sprouts than in the semi-solid media (11,3 and 9,0 respectively). The acclimatization survival index was of 96% for all treatments.
