Distribuição vertical, danos e controle cultural de Stenoma catenifer Walsingham (Lepidoptera: Elachistidae) em pomar de abacate

Stenoma catenifer Walsingham is the major pest in avocado groves (Persea americana Mill.) in the Neotropical region. Management has been difficult for many reasons related to the reduced knowledge on its bioecology and the avocado growing systems. The goal of this work was to study the vertical distribution of S. catenifer in avocado plants, the gagging effect of infested fruit on its survival, and the losses caused. The experiments were conducted in a commercial grove located at the Sao Tomas de Aquino, State of Minas Gerais, Brazil, during the 2001/2002 and 2002/2003 growing season. S. catenifer was observed especially at the lower and central part of the plant, and the inner canopy was the least attacked in comparison with the north, south, east and west quadrants. These results may be important indicators for the use of am adequate sampling procedure. The highest percentage of attacked fruit had one to four larvae; in some cases up to eight individuals per fruit were found. The losses caused by the borer varied during the agricultural season, with figures close to 5% in a single evaluation, and the harvest loss may reach 27%. The bagging of infested fruit caused mortality of S. catenifer, as observed through the evaluation carried out four days later.

Distribuição de poros e densidade de latossolos submetidos a diferentes sistemas de uso e manejo

Man cultivates the soil for centuries, but the intensive business and use of the soils under Cerrado vegetation for agricultural production grew out of the seventies. The objective of this study was to evaluate soil physical characteristics as a function of sampling time and the soil uses in a Cerrado area in Uberlandia City - MG, Brazil. The managements were adopted: degraded pasture (M-1), conventional tillage (M-2), minimum tillage (M-3), tillage absence (M-4), no-tillage (NT) for three years (M-5); NT for nine years (M-6), NT for three years after Pinus (M-7), PD for one year after Pinus (M-8) and Pinus forest (M-9) with 25 years old. The evaluations were conducted in 2002/03 growing season, in two areas. The soils were: area 1, an Oxisol (Red Latosol - LV-1, M-1 through M-5) and area 2, two Oxisols (Red Latosol and Red-Yellow Latosol - LVA and LV-2, M-6 through M-9). The physical attributes studied changed depending of the soil class, sampling time and management systems, with emphasis on the area 2 soils, which, in general, better preserved its main physical attributes. Managements with intense tillage, such as the M-2, are the most soil physically degrade, presenting mostly negative changes to soil bulk density, total porosity, microporosity and macroporosity. Since the systems which promote less tillage, in short term, to preserve desirable physical attributes. The M-9 system had the lowest attributes range, compared to the others.

Estudo da distribuição dos casos de Diabetes Mellitus em Presidente Prudente - SP

The main causes of illness and consequent death in patients affected by Diabetes Mellitus are the long-term complications. Depression can make it harder to control the level of glucose in the blood, as well as intensifying and worsening the clinical complications, thus reducing the quality of life. The aim of this study was to estimate the incidence of Diabetes Mellitus in Public Health Clinic in Presidente Prudente (SP) in patients enrolled in the Hiper-Dia Program. From October 2003 to July 2004, a descriptive survey was carried out. Data were obtained from doctor's records of 50 diabetes patients and also their answers to a specific questionnaire. The majority of the patients were female, had not completed elementary school, with a family income below five minimum wages, a nationally-defined amount related to the poverty line. It was observed that 24% of the patients had depression and 76% never followed a controlled diet. Pharmacological treatment was prescribed for 82% of the patients. Twenty-eight patients were receiving psyicological treatment, together with oral hypoglycemic agents. The glycated hemoglobin was measured in 68%. The association between depression and submission to treatment was not significant. No statistical association was found between the psychologically assisted patient's group and glucose control (p= 0.40), diet control (p= 0.37) and physical activities (p= 0.77). It was concluded that 24% patients had depression and the majority not under diet control, but 82% were under pharmacological treatment.

Situação da agricultura irrigada no Brasil de acordo com o censo agropecuário 2006

Knowledge about irrigated agricultural area and its geographical distribution are of great importance to water resources management. Evolution of irrigated area according to the irrigation method allows an identification of rational water technologies. The aim of this work was to analyze the information presented in the agricultural census of 1995/1996 and of 2006. Brazil has an area of 4.45 million cultivated hectares with irrigation. It is noticed that according to the 1995/1996 census, the irrigated area increased 1.3 million hectares, a growth of 42%. The Southeast region surpasses the South region which had, in 1995/96, the largest irrigated area. The Northeast region is the third irrigated agricultural area with 22.12 %, while the Central-west and the Northern region together sum 14.7%. According to the agricultural census 2006 classification, sprinkler irrigation (without center pivot) method is the most used,followed by flood, center pivot, other methods, drip and furrow, representing 35.3%, 24.4%, 18.9%, 8.3%, 7.4% and 5.8%, respectively.
