title: MICROBIOLOGICAL CHARACTERISTICS OF WHOLE MILK AND DAIRY DRINK PROCESSED BY UHT (ULTRA-HIGH TEMPERATURE) DURING ITS SHELF LIFE

description: ABSTRACT UHT milk and dairy drinks are submitted to the same heat treatment, but they are different products, since the addition of up to 50% of whey is allowed in dairy drinks. The aim of this study was to evaluate the microbiological characteristics of these products in relation to current legislation, during the course of their shelf life. In the present study, 150 samples, 75 of each type of product, from 5 different national brands were analyzed. The 15 samples of each brand were separated into 3 lots containing 5 samples each, analyzed at the beginning, middle and end of the validity period. Upon microbiological analysis all UHT milk samples were in conformance with current legislation. After the samples were opened and chilled for 48 hours, 26.6% of them presented an increased psychrotrophic population. The dairy drink results showed that 12% of the samples were out of conformance with the current legislation. After the samples were opened and chilled for 48 hours, 36% of them presented an increased psychrotrophic population. These results should be considered as an alert in regard to the need for rigorous inspection of UHT milk and dairy drink products.

title: SUSCEPTIBILITY TO ANTIMICROBIAL DRUGS AND PRODUCTION OF BETA-LACTAMASE BY STAPHYLOCOCCUS STRAINS ISOLATED FROM MASTITIS IN GOATS IN THESEMI-ARID REGION OF PARAIBA STATE, BRAZIL

description: ABSTRACT The present study was aimed to test the in vitro antimicrobial susceptibility using disc diffusion assay and minimum inhibitory concentration (MIC) values, as well as the production of beta-lactamase of 42 strains of Staphylococcus sp. isolated from subclinical mastitis in goats in the semi-arid region of Paraiba state, in Brazil. To this end, 14 samples of negative Staphylococcus chromogenes, 10 S. waneri, 6 S. saprophyticus, 5 S. aureus, 3 S. epidermidis, 2 S. intermedius and 2 Staphylococcus were used. Regarding the in vitro susceptibility, the highest levels of resistance observed concerned penicillin (66.67%) and ampicillin (63.89%), and the greatest sensitivity observed concerned Cefoxitin (97.22%). Multiple resistance to 3 or more antimicrobial drugs was observed in 42.86% of the isolates. Of the total Staphylococcus isolated, 73.81% were positive for the beta-lactamase production test. The minimum inhibitory concentration showed 100% of the samples susceptible to norfloxacin, and the maximum resistance values to the other antimicrobial drugs were 30%. According to the results obtained, it is concluded that, in order to select the most appropriate drug to treat mastitis in goats caused by strains of Staphylococcus, the antimicrobial sensitivity profile of the strain must be known and routine laboratory tests for detecting beta-lactamase should be performed because these enzymes are disseminated both in human and veterinary medicine. The high resistance to penicillin and ampicillin demonstrates the limitation in the use of antibiotics in the treatment of mastitis in goats. Although in the present study the cephalosporines demonstrated a considerable degree of sensitivity, the use of these antimicrobial agents in veterinary medicine becomes a matter of concern due to the incidence of strains that produce betalactamase.

title: SURVIVAL OF WORKERS OF THE TERMITE CORNITERMES CUMULANS (KOLLAR, 1832) (ISOPTERA: TERMITIDAE) FED WITH DIFFERENT DIETS

description: ABSTRACT We evaluated the survival of the termite Cornitermes cumulans (Kollar, 1832), isolated from the colony and kept on different artificial diets in the laboratory (21 ± 1° C, 90 ± 10% UR and 24h of scotophase), in Lavras, Minas Gerais, Brazil. Fifty termite workers were isolated in each plastic Petri dish, where they were offered diets or not. We used 6 replicates per treatment, evaluating the daily survival of termites until the death of all the individuals. The results were submitted to Weibull survival analysis and the equations were subjected to the test of identity of non-linear models. There was a difference in estimated survival of termites treated with different diets. It was concluded that it is possible to keep Cornitermes cumulans workers alive and isolated from the colony with the use of a diet containing filter paper, bagasse cane sugar and agar as a food source.

title: SEROPREVALENCE AND RISK FACTORS ASSOCIATED TO NEOSPORA CANINUM IN FEMALE BOVINES FROM THE WESTERN SÃO PAULO STATE, BRAZIL

description: ABSTRACT The prevalence of anti-Neospora caninum antibodies was evaluated in 1104 cows from 118 farms in the Western region of São Paulo State, Brazil, using indirect immunofluorescence antibody assay. Sixty-five (55.0%; CI 95%: 46.0-63.8%) farms showed at least one seropositive animal. Prevalence over 10% was observed in 33 farms (28.0%; CI 95%: 20.4-36.5%), and over 20% in 18 farms (15.2%; CI 95%: 9.5-22.6%). Prevalence of animals showed 120 (10.9%) positive females (IFAT ? 1:100). The positivity in the farms showed significant association with farms producing more than 50 liters per day. Infection caused by the protozoan N. caninum occurs in the Western region of the state of São Paulo, and although no differences were observed either in relation to the production type or management practices, greater milk yield was related to greater prevalence of infection.

title: MYCELIAL KINETICS OF EDIBLE FUNGI PLEUROTUS OSTREATUS AND LENTINULA EDODES IN LIGNOCELLULOSIC RESIDUES

description: ABSTRACT The objective of this work was to evaluate the mycelial growth of 2 edible fungi (Pleurotus ostreatus and Lentinula edodes) in 6 culture media [(malt-agar, sawdust-dextrose-agar-marupá (SDA-MA), sawdust-dextrose-agar-cajuí (SDA-CA), sawdust-dextrose-agar-açaí (SDA-AÇA), sawdust-dextrose-agar-banana 50% (BAN 50%) and sawdust-dextrose-agar-banana 100% (BAN 100%)], in Petri dishes. The experimental design was totally randomized, in a 6x2 factorial scheme. Each treatment consisted of six repetitions in 1 Petri dish, totaling 72 experimental units. It was verified that P. ostreatus presented better mycelial development (81.00; 64.66; 81.00; 50.16 and 33.33mm for SDA-MA, SDA-CA, SDA-AÇA, BAN 50% and BAN 100%, respectively) than L. edodes (32.00; 31.66; 27.66; 37.33 and 21.83mm for SDA-MA, SDA-CA, SDA-AÇA, BAN 50% and BAN 100%, respectively). It was also verified that there was no advantage for L. edodes in relation to mycelial growth, when media based on residues were used, compared to malt-agar medium (control), which obtained the best performance (62.17mm). As for P. ostreatus, SDA-MA and SDA-AÇA medium presented the highest growth averages (81 mm), representing a growth increase of 34% in relation to the control medium (malt-agar), whose growth average was 60.33mm. Thus, the residues tested present potential to be used in fungiculture, especially for the cultivation of P. ostreatus.

title: INTERACTION BETWEEN TRANSGENICS AND INSECTICIDES IN THE CONTROL OF KEY PESTS ON OFF-SEASON MAIZE HYBRIDS

description: ABSTRACT Diverse lepidopteran pests attack the maize crop. The commercialization of hybrids of transgenic Bt maize, integrating in its genome the gene Cry1Ab, from Bacillus thuringiensis subsp. kurstaki, which codifies the protein with toxic effect on insects of the Lepidoptera order, has been recently introduced in Brazil. The objective of this work was to evaluate, under field conditions, the effectiveness of conventional and transgenic maize hybrids for the control of pests, sprayed or not with insecticides. The assay was carried out in an experimental area of the Polo Apta Centro Norte, in Pindorama, São Paulo State, Brazil. Five conventional maize hybrids were evaluated in comparison with the respective isogenic Bt hybrids. The evaluation was carried out every 10 days, in 20 plants of the 2 central lines of the parcel for Spodoptera frugiperda (Smith) damage. For damages of Helicoverpa zea (Bod.) and Diatraea saccharalis (Fab.) the evaluations were carried out in the pre-harvest. The interactions between the hybrids and the transgeny occurred in all evaluations starting at the 40th day after emergence (DAE). The Bt hybrids evaluated presented the lowest scores for visual S. frugiperda damages in all the evaluations. The transgenic maize also provided the lowest percentage of cobs damaged by H. zea and S. frugiperda, and of stalks attacked by D. saccharalis. In conclusion, the transgenic maize provided reduction in visual damages caused by the pests, however, it presented different performance among the hybrids.

title: IN VITRO INHIBITION OF FUNGAL PLANT PATHOGENS BY DIFFERENT CONCENTRATIONS OF MEDICINAL PLANTS EXTRACTS

description: ABSTRACT In order to evaluate the in vitro effect of different concentrations of plant extracts on the growth of Cercospora kikuchii. Fusarium solani. Colletotrichum sp. and Phomopsis sp., 4 bioassays experiments were conducted at the Plant Pathology Laboratory of the Federal University of Grande Dourados, Brazil. The experimental design was a completely randomized design in a 3 x 6 factorial arrangement, with 8 replicates for each bioassay. Aqueous extracts of garlic, cinnamon and clove were evaluated in concentrations of 0, 0.5, 1, 5, 10 and 20%. Extracts were obtained through maceration of 30 g of plant material in 120 mL of distilled water. The extracts were filtered in grade-1 Whatman paper and incorporated into PDA medium to obtain the desired concentrations. Subsequently, the solution was poured into Petri dishes, and then 3 mm-diameter-PDA plugs with pathogen mycelium were transferred to the center of the PDA + plant extract Petri dish. Plates were incubated at 25° C with a 12-h-day photoperiod. Fungal growth was performed daily by measuring the colony diameter. The results showed that the effect of aqueous extract of cinnamon for all pathogens studied, and garlic extract for F. solani. Colletotrichum sp. and Phomopsis sp., was dependent on the concentrations used, noting a higher antifungal activity with increased concentrations used. Clove extract presented the greatest effectiveness for the control of the plant pathogens tested, with observed suppression on the growth of Colletotrichum sp. C. kikuchii. F. solani and Phomopsis sp. at the concentrations 7.4, 7.5, 8.9 and 7.0%, respectively. The aqueous extract of garlic at a concentration of 9.7% presented effective control only for C. kikuchii.

title: REACTION OF YELLOW PASSION FRUIT TO MELOIDOGYNE INCOGNITA RACE 3

description: ABSTRACT This study concerned the reaction of yellow passion fruit ‘Maguary’ and ‘Afruvec’ to the phytonematode Meloidogyne incognita race 3 in greenhouse conditions. An entirely randomized experimental design with 3 treatments (‘Maguary’, ‘Afruvec’, and tomato cv. ‘Rutgers’) and 4 repetitions was used, each plot consisting of 1 vase containing 1 plant. After 6 months, an evaluation was made of the index of galls and egg mass in the yellow passion fruit varieties and in the tomato cv. ‘Rutgers’. The classification of resistance to the phytonematode was made by criterion of the reproduction factor (RF). ‘Maguary’ presented a zero index of galls and egg mass, while ‘Afruvec’ showed a low index of galls and egg mass in relation to the tomato cv. Rutgers. According to the RF, ‘Maguary’ was characterized as immune to the phytonematode, while ‘Afruvec’ was resistant, and the tomato cv. ‘Rutgers’ was susceptible.

title: EFFECT OF DIFFERENT HERBICIDES, DOSES AND SPRAY VOLUME IN THE CHEMICAL MANAGEMENT OF PEARL MILLET [PENNISETUM GLAUCUM (L. LEEK)]

description: ABSTRACT The objective of this work was to evaluate the efficacy of different herbicides applied in post-emergence in the desiccation of pearl millet with different doses and spray volumes. For the desiccation, doses at 0, 25, 50 and 100% of the herbicide glyphosate (1,440 g ha-1) were used in 3 formulations (Original Round up, Round up Transorb and Round up WG), paraquat + diuron (500 + 250 g ha-1) and glufosinate-ammonium (800 g ha-1). In all treatments, 2 spray volumes (200 and 400 l ha-1) were used, and there was 1 treatment (control) without the application of herbicides. The treatment effects were evaluated visually at 3, 7, 14, 21 and 28 days after application (DAA). At the end of the evaluations, the dry mass of the plants was determined. The field trial was carried out in randomized block design. At the end of the study, at 28 DAA, all treatments presented total control of plant pearl millet, regardless of the dose and spray volume, except the treatments with paraquat + diuron and glufosinate-ammonium at the lower dose (25%), in 2 spray volumes, which nevertheless showed good and very good control, these two herbicides presenting an effect of volume, in which the control was higher with the use of smaller volume.

title: TRICHOGRAMMA SPP. (HYMENOPTERA: TRICHOGRAMMATIDAE) SPECIES AND STRAINS FOR THE CONTROL OF ANTICARSIA GEMMATALIS (LEPIDOPTERA

description: ABSTRACT Several Trichogramma (Hymenoptera: Trichogrammatidae) species parasitize Anticarsia gemmatalis (Lepidoptera: Noctuidae) eggs, the major soybean desfoliator in Brazil. The objective of this work was to evaluate the parasitism of eleven Trichogramma species/strains in cardboards with twenty eggs of A. gemmatalis by this parasitoid female for 24 hours. The strain trat - 2 Trichogramma atopovirilia (Hymenoptera: Trichogrammatidae) of Sete Lagoas, Minas Gerais, showed better performance with 19 A. gemmatalis eggs parasitized by female in 24 hours, 98% viability and sex ratio of 0.84. The strain Trichogramma pretiosum of Crystalline, Goiás, parasitized 11.9 A. gemmatalis eggs per female with 98% viability and sex ratio of 0.65. This work confirms the importance of evaluating Trichogramma strains before biological control programs, because different strains of the same species of parasitoid have distinct results.

title: BOVINE BRUCELOSIS IN THE STATE OF PARAÍBA: A RETROSPECTIVE SURVEY

description: ABSTRACT The aim of this study was to determine the frequency of positive herds (foci) and seropositive animals for bovine brucellosis in the state of Paraíba, Northeast region of Brazil. Data from the Agency of Agricultural Protection in the state, collected from its 23 microregions, during the period from January 2008 to July 2009, were used. During this period, 11,149 herds were examined, and 55,691 cattle sera were submitted to the diagnosis of brucellosis. For serological diagnosis the rose bengal test was used. A herd was considered a focus when it presented at least one seropositive animal. Of the herds investigated, 104 (0.93%) had at least one seropositive animal, and of the animals examined, 199 (0.36%) were seropositive. There was a significant difference (p &lt; 0.001) in the proportion of seropositivity for females (0.47%) and males (0.04%).

title: COLD STORAGE OF TRICHOGRAMMA PRETIOSUM RILEY (HYMENOPTERA: TRICHOGRAMMATIDAE)

description: ABSTRACT The objective of this work was to evaluate the effect of storage at low temperature of Trichogramma pretiosum pupae in eggs of Sitotroga cerealella on the emergence and reproduction rates of the parasitoid. The trials were conducted in a climatic chamber at 5, 8 and 10º C, 70% R.H., constant scotophase, with 10 treatments: 4, 6, 8, 10, 12, 14, 16, 18, 20 days of storage and a control not kept in storage, all in 10 replicates. A total of 1,000 eggs containing pupae were distributed in glass tubes (10 x 3 cm), 100 of which were kept at 25° C, 70% RH and 14 h photophase (control), while the remaining ones were stored. After each storage period 100 eggs were transferred to 25º C and the emergence and reproductive capacity were observed. The T. pretiosum emergence rate was not affected by the storage time at 3 temperatures (Tukey P ≤ 0.05) and the lowest emergence rates were 85.6%, 84.5% and 77.6%, respectively for parasitoid storage at 5, 8 and 10º C. The reproductive capacity of T. pretiosum was not affected after the exposure periods in the temperatures evaluated. This result will aid in the planning of mass production, package and transport of T. pretiosum to the place of release.

title: EFFECT OF SILICON ON THE INTENSITY OF BROWN EYE SPOT AND ON THE MINERAL NUTRITION OF COFFEE SEEDLINGS

description: ABSTRACT Our objective was to verify the effect of silicon on the intensity of brown eye spot and on the mineral nutrition of coffee seedlings. In the first experiment, 6 doses of silicic acid (0, 0.5, 1, 2, 4 and 6 g kg-1 soil) were tested using a complete randomized block design with 4 replicates with 6 coffee seedlings cultivar Catuaí Vermelho IAC 99 inoculated with the fungus Cercospora coffeicola. In the second experiment, X-ray microanalysis in a scanning electron microscope was performed on 2 coffee cultivars (Topazio MG1190 and Icatu Precoce IAC 3282), inoculated and non-inoculated with C. coffeicola, treated and untreated with calcium silicate (1 g kg-1 of soil). With the increase of the silicic acid doses, there was observed a reduction in the area under the disease progress curve of the number of lesions per leaf (AUPCNLL), coupled with a linear reduction in the foliar contents of magnesium and phosphorus as well as an increase in the contents of sulfur and copper. The foliar contents of boron presented a quadratic behavior, decreasing with the increase of silicic acid and increasing with the dose of 4 g kg-1 of soil. In X-ray microanalysis, coffee seedlings with brown eye spot presented lower peaks of potassium and calcium, regardless of the cultivar used.

title: MORPHOMETRY OF ANASTREPHA FRATERCULUS (WIED) (DIPTERA: TEPHRITIDAE) RELATED TO NATIVE MYRTACEAE HOSTS

description: ABSTRACT The fruit-fly Anastrepha fraterculus uses the myrtacean fruits as its main primary hosts. The insect size might be an indicator of aptitude and fecundity, and morphometric studies are used to help in those identifications. This study aimed to verify the association among fruit weight, puparial weight and wing size of fruit-flies that developed in different myrtacean species. Yellow strawberry guava, cattle guava, guava and feijoa fruits were sampled from 5 trees of each species. The fruits were weighed, and the puparia originated from them were also weighed and individualized. The number, gender and total right-wing area of the flies were registered. Mean fruit and puparial weights and wing sizes were compared. Mean puparial weight was higher in guava and cattle guava. The largest mean wing area was recorded for individuals from guavas; the smallest, for those from yellow strawberry guava. The fruit and puparial weights did not present a significant association in yellow strawberry guava, cattle guava and feijoa. In guavas, the correlation between fruit and puparial weights was negative. The fruit weight and wing area in all myrtacean species did not show any correlation. These results indicate the fly is able to develop similarly in all sampled myrtacean species.

title: EVALUATION OF OREGANO AND ROSEMARY ESSENTIAL OILS FOR THE PREVENTION OF NEONATAL DIARRHEA IN PIGLETS

description: ABSTRACT In order to verify the preventive effect of the liquid emulsion of a mix of essential oils of oregano (Origanum vulgare) and rosemary (Rosmarinus officinalis) in the control of neonatal diarrhea in nursing piglets, an experiment was conducted using a randomized experimental design composed by two simple treatments. Piglets from the same litter, born to females with different orders of births, were divided into two groups of piglets without clinical signs of neonatal diarrhea. The first group of 661 pigs received the control treatment (1 mL kg-1 saline) while the second group with 672 animals received essential oils of oregano (60% carvacrol and 15% thymol) and 2% essential oil of rosemary in the form of a 5% liquid emulsion at a dose of 1 mL kg-1. All the treatments were administered orally on the first and third day of the piglets’ life, and in regard to the index parameter for the prevention and causes of mortality of piglets, each animal represented a repetition. There was no significant difference between the treatments related to the rate of prevention of neonatal diarrhea in piglets. The results showed that the mix of essential oils from oregano and rosemary do not prevent diarrhea in neonatal piglets.

title: CONSERVATION OF NATURAL ENEMIES (INSECTA) IN THE ORGANIC TOMATO CROP

description: ABSTRACT The adoption of cultural practices such as companion plants and the kind of irrigation system can benefit the community of natural enemies in the agroecosystem due to the increase of more favorable microhabitats available and as a source of alternative resources, mainly in periods of low precipitation. This study evaluated how the tomato + coriander intercrop and the kind of irrigation (drip and sprinkler) could benefit the community of natural enemies in the tomato agroecosystem. This work was carried out in the experimental field of Embrapa Hortaliças, Gama, DF, from September to November 2008. The tomatoes were planted in monoculture or with coriander (companion plant) and irrigated by drip and sprinkler irrigation (three replicates per treatment), forming two groups of experimental plots according to the kind of irrigation. The community of natural enemies was sampled by the direct observation of specimens on 20 tomatoes plants per plot and in the treatments. Coriander plants were shaken over a plastic tray for collection of insects. The abundance, richness and diversity of natural enemies were higher in tomato + coriander plots, regardless of the irrigation system. We observed more species of natural enemies in tomato monoculture plots when it was irrigated by sprinkler irrigation. However, the cultural practices adopted had a different effect on each species or group of species. Therefore, in periods of low precipitation, the tomato + coriander consortium associated with sprinkler irrigation can enhance the conservation of natural enemies in the organic tomato agroecosystem.
