Preferência alimentar e aspectos biológicos de Leptoglossus zonatus Dallas,1852 (Hemiptera: Coreidae) em diferentes genótipos de milho

The present research was accomplished under field and laboratory conditions (T= 25[plus or minus]2[degree] C, R.H.= 70[plus or minus] 10 % and fotoperiod= 12 horas) at FCA/UNICASTELO from Fernandopolis-SP, Brazil. The feeding preference of corn bug Leptoglossus zonatus Dallas, 1852 (Hemiptera: Coreidae) was evaluated on corn genotypes AL-Bianco, AL-Manduri, AL-25 Piratininga, AL-34 e AL-Manduri in the field. Besides, some behavioral factors relative to infestation and oviposition were observed. In laboratory, the nymph's development was evaluated on ears from each corn genotype, aiming to verify the non-preference and/or antibiosis ocurrence. The females of L. zonatus preferred to oviposite on sheats from leaves. Adults and nymphs may occur in whole parts of the plants. The AL-25, AL-34, AL-Manduri and AL-Bandeirante corn genotypes were classified as moderately resistant, expressing non-preference and/or antibiosis against the corn bug. In other way AL-Bianco was the most suscetible to nymphs of the insect.

Estimativa do conforto de matrizes de frango de corte baseada em análise do comportamento de preferência térmica

Considerando o comportamento social, é sugestivo que a freqüência e a intensidade de interações agressivas, o total de coesão social e compreensão da extensão de vícios sociais possam ser utilizados para avaliação de bem-estar. Este trabalho propõe que a freqüência de utilização de determinados locais dentro do galpão possa ser usada como variável para monitorar estados de bem-estar térmico e/ou estresse das aves alojadas. A partir de dados registrados no verão de 2000-2001, esta pesquisa identificou as temperaturas críticas máximas (tc máx) de matrizes pesadas, individualmente, por meio de análise estatística da freqüência de uso de locais previamente estabelecidos, utilizando a tecnologia de identificação eletrônica. Os valores das tc máx individuais variaram de 30 °C ± 0,2 ºC a 32,3 ºC ± 0,2 ºC e a temperatura crítica máxima média para o grupo foi 30,9 ºC ± 0,8 ºC.

Preferência alimentar da formiga urbana Camponotus vittatus forel (Hymenoptera: Formicidae)

For an adequate management program of urban ants, knowledge on their biology is required, with the aim of detecting and exploring their vulnerabilities. This type of information has been used in the manufacture of baits, which must show, among other characteristics, attractiveness to several species to be considered efficient and economically viable. Therefore, the present study was aimed to evaluate in the laboratory the attractiveness of sweet and fatty substances to Camponotus vittatus, trying to find which substances would be more efficient to be introduced as the attractive component in baits. Five colonies, 68 sweet substances and 23 fatty substances were utilized in the laboratory trials. The most attractive sweet and fatty substances, were, respectively, 75% demerara sugar and vegetable fat. When substances of both natures were tested together, sweet substances presented slightly higher attractive indexes than oily substances.

Não-preferência para alimentação de traça-das-crucíferas por genótipos de couve-flor

The feeding nonpreference of Plutella xylostella (L.) larvae was tested in regard to the cauliflower genotypes Barcelona, Verona, Piracicaba Precoce, Sharon, Silver Streak (hybrids) and Teresopolis Gigante (cultivar). Choice and no-choice tests were carried out at the laboratories of the Departamento de Fitossanidade, FCAV/UNESP, Jaboticabal, state of São Paulo, Brazil, to study attractiveness and dry mass consumption by 1st-instar (just hatched) and 4th-instar larvae for 24 hours. No significant difference was found for attractiveness in choice and no-choice tests, for both 1st-and 4th-instar larvae. The consumption of dry mass in both tests, with 1st-and 4th-instar larvae, showed a significant difference between genotypes only for 1st-instar larvae, the hybrid Silver Streak being the most consumed (3.72 mg) by P. xylostella larvae. The cauliflower genotypes tested presented no variation in attractiveness for 1st-instar (just hatched) and 4th-instar larvae and did not present nonpreference feeding resistance for P. xylostella larvae.

Preferência alimentar de adultos de Metriona elatior Klug (Coleoptera: Chrysomelidae, Cassidinae) por diferentes híbridos de Solanum melogena Linnaeus (Solanaceae)

Feeding preference of adults of Metriona elatior Klug (Coleoptera: Chrysomelidae, Cassidinae) for different hybrids of Solanum melogena Linnaeus (Solanaceae). Metriona elatior Klug is a potential biocontrol agent for Solanum viarum Dunal (tropical soda apple), because larvae and adults feed on its leaves and this species shows a low dispersion rate. Specificity plays a major role in the feasibility of an organism as a biological control agent, especially in the inundative strategy. The feeding preference of M. elatior adults was evaluated to 14 eggplant (Solanum melogena Linnaeus) hybrids. Mass rearing was carried out under lab conditions, with the insect feeding directly on S. viarum leaves. The study started with dual and multiple choice tests in 24 and 48 hour feeding times, by offering leaf disks in Petri dish conditions. Survival and leaf consumption analysis were performed in newly adults in tropical soda apple and eggplant leaves kept turgid by immersing the petioles in water. The leaf area was measured before and after four days of insect exposure. M. elatior showed higher feeding preference, survival and consumption of the weed species, especially in comparison with the hybrid Ryoma. The highest feeding preference among the eggplant hybrids was observed in 'Minikuro Kowishiki'.

Preferência alimentar de adultos de Diabrotica speciosa (Ger.) (Coleoptera: Chrysomelidae) por genótipos de feijoeiro

Tests were carried out to evaluate resistance of common bean (Phaseolus vulgaris L.) to Diabrotica speciosa (Ger.) with the genotypes Goiano Precoce, Jalo Precoce, PR 95105146, PR 95105142 (Andean domestication center, AN), Emgopa 201 Ouro and IAPAR 57 (Middle American domestication center, MA). The experiments were conducted in 1998 and 1999, at the farm of UNESP-FCAV, Jaboticabal, SP, Brazil. The genotypes were planted in pots and 20 day-old leaflets were collected and foliar disks were cut of for the test. Two trials, a no-choice test and a free-choice test, were set up in BOD. In free-choice test, two disks of each genotype were kept in a 140-mm-diameter petri dish (total of 12 disks), where 12 adults were confined. In no-choice test, two disks of one genotype and two insects were placed in a 60-mm-diameter petri dish. A field experiment was conducted when 400 adults of D. speciosa were released. Fifteen leaflets per plot were collected 30 days after planting and the leaf area consumption was evaluated. A no-choice experiment was carried out with 20 day-old genotypes protected in individual cages and infested by 10 adults, for 72h. The MA genotypes were the most preferred on feeding tests conducted at BOD, field and individual cages, while the AN genotypes were less eaten.

Uso do grau de preferência alimentar para a caracterizaç ão da alimentação de peixes na APA de São Pedro e Analândia

We studied feeding habits of four fish species in two watershed at APA - Área de Proteção Ambiental (Area of Environmental Protection) in São Pedro and Analândia, State of São Paulo, southeastern Brazil. Feeding Preference Degree (FPD) was used to demonstrate the importance of each food item for the species of both basins. Feeding habits of both species of lambari was variable. The allochtonous items such as insects, autochtonous items, and vegetal material were very important, characterizing omnivory. The bagre (Rhamdia quelen) fed mainly on insects at the Jacaré-pepira Basin and also on fishes at the Corumbataí basin. The cascudo Hypostomus strigaticeps ingested autochtonous vegetal material and sediments at both basins.

Estudo multicêntrico Brasileiro - Adesivo contraceptivo transdérmico semanal: Preferência e satisfação das usuárias

Background: To assess satisfaction with the weekly transdermal contraceptive patch, compared to the previous contraceptive method. Adhesion, cycle control, safety and efficacy were secondary outcomes. Methods: A multicenter, open label, descriptive study. Subjects received the weekly transdermal contraceptive patch for 6 cycles. At the baseline and after the 1 st, 3 rd and 6 th cycles, satisfaction with the method was assessed. The contraceptive efficacy was assessed by the Pearl Index and by life table analysis. Results: An ITT analysis was performed with 494 subjects. At the endpoint, 95.3% of women were satisfied with the patch compared to the previous method; 59.5%, 58.0% and 63.2% of women reported improvement in the physical and emotional well-being, and pre-menstrual symptoms, respectively. Pre-menstrual symptoms frequency decreased from 85.0% (CI 95%: 80.8-87.4%) to 55.0% (CI 95%: 49.9-66.0%). There was a significant increase in hemoglobin levels, and also a significant decrease in total serum cholesterol and tryglicerides.. There were no significant adverse events. The adjusted Pearl Index was 1.1 pregnancies per 100 women-years. Conclusions: The weekly contraceptive transdermal patch is a safe and effective method, and there was a high rate of satisfaction with its use among brazilian women. The patch was associated to a good cycle control, with easiness of use, improvement in the physical and emotional well-being and improvement in the premenstrual symptoms and lipid profile. © Copyright Moreira Jr. Editora.
