The predators were collected in mate crop in Cascavel and São Mateus do Sul, Paraná, Brazil and some other additional specimens in coffee and maize crops in Ribeirão Preto, São Paulo, Brazil. Illustrations obtained by SEM are given by the first time to the principal structures. Three species of Hemerobius were identified: H. bolivari Banks, 1910; H. domingensis Banks, 1941 and H. gaitoi Monserrat, 1996. H. domingensis is recorded for the first time to Brazil.

Este trabalho teve como objetivo verificar se o horário de colheita da erva-cidreira brasileira [Lippia alba (Mill.) N. E. Br.], fenotipo carvona-limoneno, tem influência sobre a produção de massa foliar, rendimento e composição do óleo essencial. Foram avaliados cinco horários de colheita quando a cultura estava com 145 dias desde o transplante: 8:00, 10:00, 12:00, 14:00 e 16:00 h com cinco repetições, distribuídos em blocos casualizados. O experimento foi conduzido na Fazenda Experimental Lageado da FCA-UNESP/Botucatu no Setor de Horticultura do Departamento de Produção Vegetal. A colheita foi realizada a 15 cm da superfície do solo e o óleo essencial obtido através de hidrodestilação, em aparelho tipo Clevenger. Levou-se em consideração os fatores agronômicos e o rendimento obtido por hidrodestilação. O óleo essencial foi analisado em cromatógrafo gasoso acoplado a espectrômetro de massas (CG/EM). Os resultados foram submetidos à análise de variância (Teste F) e as médias comparadas pelo teste de Tukey. Não houve diferença estatística para produção de massa foliar, teor de óleo essencial e produtividade de óleo essencial em massa fresca e seca. No entanto, entre os compostos majoritários do óleo essencial das folhas, carvona e limoneno, a melhor produtividade de carvona foi obtida às 10:00 h, em matéria fresca (2,050 L ha-1) e em matéria seca (2,068 L ha-1), e para o limoneno às 16:00 h, em matéria fresca (1,068 L ha-1) e em matéria seca (1,060 L ha-1).

Lippia alba, espécie brasileira da família Verbenaceae, é plantada e usada em todo o Brasil por suas atividades farmacológicas como analgésica, antiespasmódica, calmante, sedativa e citostática. Popularmente a Lippia é denominada de alecrim, cidreira falsa ou falsa melissa. O trabalho visou testar o efeito das aplicações de GA3, ethephon e CCC sobre o crescimento de Lippia alba (Mill.) N.E.Br. - Verbenaceae, em diferentes épocas do ano. O experimento foi instalado na Fazenda São Manuel, pertencente à UNESP em Botucatu, de dezembro/95 a dezembro/96. O mesmo consistiu de sete tratamentos e três repetições em blocos inteiramente casualizados, com os tratamentos aplicados nas parcelas e as colheitas nas subparcelas. Os tratamentos incluíram o controle, ácido giberélico (GA3 50 e 100 mg.L-1), ácido 2-cloroetil-fosfônico (ethephon- 100 e 200 mg.L-1) e cloreto de 2-cloroetil-trimetil amônio (CCC 1000 e 2000 mg.L-1). Os reguladores vegetais foram aplicados em duas épocas, aos quarenta e cem dias da implantação do experimento no campo e o crescimento das plantas foi avaliado em seis épocas. Após a primeira aplicação as plantas foram coletadas em intervalos de 14 dias. Os fitorreguladores GA3, e CCC tenderam a elevar os resultados das características, matéria seca de caule, folhas, flores e total, porém sempre permaneceram menores ou iguais ao controle.

A greenhouse experiment was conducted in the Soil Science Department of the Botucatu College of Agricultural Sciences (UNESP), Brazil, using a Dark Red Latosol in 25 L pots. The soil was limed to 50 and 70% of base saturation; and doses 0, 10, 20, 30 and 40 t ha-1 of chicken manure were applied, in December of 1999. The experimental design was completely randomized blocks with a factorial arrangement 5x2, 10 treatments and three replications. This work was carried to evaluate leaf number, height plants, fresh and dry weight by aerial part of sweet fennel, and macronutrients and micronutrients removal. The organic fertilization affected the accumulation of N, P, K, S, B and Mn; liming affected the nutrient uptake, except for the Ca, Mg, S and Fe; the interaction of factors affected K, Mg and Mn.

The buttonweed (Spermacoce latifolia) is becoming a plant among the most current infesting eucalypts plantation in State of São Paulo due to the continual use of same herbicides and control methods. Owing this, this work aimed to evaluate the effects of periods of company and control of S. Iatifolia on the initial growth of Eucalyptus grandis, planted in winter and summer. Only one seedling of Eucalyptus was planted in amianthus cement box and submitted for crescent periods of company and control of S. Iatifolia (0, 20, 60 and 80 days in competition or not). The densities of plants of S. Iatifolia were 4 and 16 plants per m 2 (under winner and summer conditions). The experimental period was 100 days after the planting (DAP). The experimental design for both experiments was the completely randomized blocks (CRB) with ten treatments and four replicates. The results of plant high, stem diameter, dries weights and leaf area showed that the before interference period (BIP), whole period of prevention for interference (WPPI) and critical period of prevention for interference (CPPI) were 40, 60, and 60 DAR, respectively, under winner conditions. Under summer conditions, the WPPI and CPPI were 20, 80 and 20 to 80 DAR.

This work aimed to evaluate the carcass yields, commercial cuts and non-carcass components of Santa Inês lambs fed with 30, 40, 50 or 60% of oldman saltbush hay with concentrated. Were used 32 castrated lambs at 8 months old and initial body weight of 22 + 1.97kg, housed individually and slaughtered after 60 days of feedlot. The weights of hot and cold carcass decreased linearly with the inclusion of saltbush hay in the diet, however, there was no effect for true carcass yield and commercial cuts: shoulder (19.26%), neck (8.52%) ribs (26.57%) and leg (33.88%). There was a linear decrease for ribeye area and fat thickness when the level of hay in the diet increased. The weights and yields of skin, liver, heart, kidneys with perirenal fat, omental and mesenteric fats decreased linearly with the inclusion of hay in the diet, while the content (%) of gastrointestinal tract increased. The increased proportion of saltbush hay in the diet of lambs provided adequate true carcass yield and commercial cuts, however, reduces the ribeye area and fat thickness, important measurements in the qualitative evaluation of the lamb's carcass.

Introduction: Physical exercise are related to high oxygen consumption, leading to increase on reactive oxygen species (ROS) generation and subsequent oxidative stress. Concomitantly, physical training can improve the antioxidant defense systems, reducing the deleterious activity of ROS. The yerba mate (Ilex paraguariensis) has several bioactive compounds in its composition, providing important antioxidant activity in improving defense systems and reducing the damage caused by ROS. Few studies related to yerba mate with antioxidant effects during exercise. Objective: Evaluate whether the consumption-based drink yerba mate (Ilex paraguariensis) is able to increase the total antioxidant performance (TAP) after an exhaustive test on a treadmill. Methods: The sample counted with 15 female soccers players from Botucatu-SP female soccer team with a mean age of 22.1 ± 4.2 years. For laboratory tests , it was evaluated: triglycerides (TG), total cholesterol (TC) and fractions, glucose and gamma-GT were dosed by dry chemistry (Vitros® System, Johnson & Johnson). LDL-cholesterol was obtained by Friedwald formula. Total antioxidant performance (TAP) was obtained by the method of fluorescence assay for the measurement of plasma. Weight, height and body mass index (IMC) were measured, percentage of body fat was obtained by bioeletrical impedance analysis (Biodinâmics, modelo 450, USA). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Ramp Protocol). Maltodextrin was supplemented (30 g in 400 ml) 30 minutes after M0 with placebo (400 ml) or mate (5 g in 400 ml of water). Statistical analysis: ANOVA for repeated measures followed by Tukey's test set, p<0.05. Results: There was a decrease in the pH after exhaustive testing for water and tea (p<0.0001), the same was observed for bicarbonate (p<0.0001). In both groups pO₂ increased for ...
