Toxicity of Pesticide Tank Mixtures from Rice Crops Against Telenomus podisi Ashmead (Hymenoptera: Platygastridae)

The use of insecticides, herbicides, and fungicides commonly occurs in mixtures in tanks in order to control phytosanitary problems in crops. However, there is no information regarding the effects of these mixtures on non-target organisms associated to the rice agroecosystem. The aim of this study was to know the toxicity of pesticide tank mixtures from rice crops against Telenomus podisi Ashmead (Hymenoptera: Platygastridae). Based on the methods adapted from the International Organisation for Biological and Integrated Control of Noxious Animals and Plants (IOBC), adults of T. podisi were exposed to residues of insecticides, herbicides, and fungicides, individually or in mixture commonly used by growers, in laboratory and on rice plants in a greenhouse. The mixture between fungicides tebuconazole, triclyclazole, and azoxystrobin and the mixture between herbicides cyhalofop-butyl, imazethapyr, imazapyr/imazapic, and penoxsulam are harmless to T. podisi and can be used in irrigated rice crops without harming the natural biological control. The insecticides cypermethin, thiamethoxam, and bifenthrin/carbosulfan increase the toxicity of the mixtures in tank with herbicides and fungicides, being more toxic to T. podisi and less preferred for use in phytosanitary treatments in the rice crop protection.

Proposta de um teste de hipótese para a existência de dependência espacial em dados geoestatísticos

A avaliacao da significância da dependencia espacial e importante para que se possa realizar uma inferencia formal sobre a hipotese nula de nao existencia de dependencia espacial em Geoestatistica. Com o presente estudo, objetivou-se construir um teste de significância para a hipotese nula de ausencia de dependencia espacial, para uma melhor decisao sobre a existencia ou nao de dependencia em dados geoestatisticos. Para a construcao do teste de dependencia espacial levou-se em consideracao as caracteristicas dos modelos ajustados ao semivariograma e, para a construcao do teste de hipotese, inicialmente, foram definidos a hipotese nula e uma estatistica de teste gerada a partir do conceito de area de dependencia espacial obtida no semivariograma. O teste foi construido com base em simulacoes de fenomenos geoestatisticos apresentando caracteristica de efeito pepita puro, ou seja, fenomenos em que a hipotese nula foi verdadeira. Por fim, foi estudado o poder do teste para diferentes graus de dependencia espacial simulados. O teste apresentou bom poder, sendo que este tendeu a 100% quando aumentou o grau de dependencia espacial dos fenomenos geoestatisticos simulados.

Side-effects of pesticides used in irrigated rice areas on Telenomus podisi Ashmead (Hymenoptera: Platygastridae)

Telenomus podisi Ashmead (Hymenoptera: Platygastridae) is an important agent for the biological control of stink bug eggs in irrigated rice areas and the best strategy for its preservation is the use of selective pesticides. The aim of this study was to know the side-effects of pesticides used in Brazilian irrigated rice areas on egg parasitoid T. podisi. We evaluated, under laboratory conditions, 13 insecticides, 11 fungicides, 11 herbicides, and a control (distilled water) in choice and no-choice tests. In the no-choice tests, the pesticides were sprayed at pre and post-parasitism stages (egg and larval stages of T. podisi). In the choice tests, sprays were conducted only at pre-parasitism stages. For all tests, we prepared cards with 25 eggs of the alternative host Euschistus heros (Fabricius) (Hemiptera: Pentatomidae) non-parasitized (pre-parasitism) and parasitized (post-parasitism), which were subjected to pesticide sprays. The parasitism and emergence rates of T. podisi were determined classifying the pesticides in terms of the reduction of parasitism or emergence rates compared to the control. The neurotoxic insecticide cypermethrin, lambda-cyhalothrin, zeta-cypermethrin, etofenprox, thiamethoxam, thiamethoxam + lambda-cyhalothrin, acetamiprid + alpha-cypermethrin, and bifenthrin + alpha-cypermethrin + carbosulfan were more harmful to T. podisi and, therefore, are less suitable for the integrated management of insect pests in irrigated rice areas.

Análise do desenvolvimento motor e qualidade do ambiente domiciliar de crianças pré-escolares

Objective – The aim of this study was to analyze the motor development and quality of the household environment of children. Methods – This is a descriptive and quantitative study, conducted with 44 children between 18-42 months of private educational institutions for children in the Central Santa Maria, RS. Affordance in the Home Environment for Motor Development - Self Report and Peabody Developmental Motor Scales-2 were used to evaluate the household environment and motor development. Results – The main age was 31.6 months, 59.09% were female and 40.91% male, 50% live in apartment, 72.72% of households provide sufficient opportunities for motor development. The sub-tests that showed the best and worst motor performance were: fine manipulation and locomotion. Regarding the Total Motor Quotient, 63.64% are children with an average score.

Avaliação da modulação autonômica cardíaca no processo de enchimento da bexiga em mulheres com incontinência urinária: perspectiva da fisioterapia

Comparou-se o comportamento do sistema nervoso autonomo, por meio da variabilidade da frequencia cardiaca (VFC), durante as fases de enchimento vesical de mulheres com e sem incontinencia urinaria (IU). Aplicou-se o International Consultation on Incontinence Questionnaire - Short Form, para autodiagnostico de IU. Para analise da VFC utilizaram-se registros de eletrocardiograma (ECG), sendo 6 registros durante o enchimento vesical. Para quantificar a VFC utilizaram-se os metodos: dominio do tempo (milissegundos); frequencia (Hertz) e medidas nao lineares. A estes parâmetros aplicou-se transformacao logaritmica (Log). Na comparacao de medias de dados normais utilizou-se teste t e para os dados nao normais o teste de Mann-Whitney. Participaram 64 mulheres (64,8±6,73 anos), 33 com IU e 31 continentes. A variavel logaritmo da razao dos componentes LF e HF (LogLH/HF) foi significativamente maior (p<0,05) no grupo continente em todos os momentos do enchimento vesical. A capacidade volumetrica vesical foi significativamente maior nas mulheres continentes (p=0,0015). A analise no dominio da frequencia demonstrou reducao da funcao simpatica e aumento do parassimpatico nas mulheres incontinentes. As mulheres continentes apresentaram melhor balanco autonomico durante todo processo de enchimento vesical, em comparacao as incontinentes. A reducao da funcao simpatica, bem como o aumento da funcao parassimpatica nas incontinentes, pode ser reportada para uma diminuicao da capacidade de relaxamento do detrusor e um aumento das contracoes, ainda na fase de enchimento vesical, ambos associados a IU.

VALIDAÇÃO DO ARRANJO ESPACIAL DO PERCEVEJO-DO-COLMO EM ARROZ IRRIGADO POR INUNDAÇÃO

In order to spatial arrangement validation of Tibraca limbativentris Stal, 1860 (Hemiptera: Pentatomidae) in flooded rice field located at the “Planalto da Campanha” Region, Rio Grande do Sul (RS), Brazil, was carried out a study in flooded rice fields at Itaqui, Rio Grande do Sul State, Brazil, in the 2009/10, 2010/11 and 2011/12 harvests. Were established georeferenced grids for the samplings, totaling 81 points spaced ~50 m in the 2009/10 harvest and, 693 and 352 points in the 2010/11 and 2011/12 harvests, respectively, both with equidistant points ~10 m. Adults and nymphs samplings were performed on each point of the regular grids. We conducted a descriptive statistical analysis for the adults, nymphs and adults + nymphs variables by calculations the mean, standard deviation and minimum and maximum values and dispersion indices: variance/mean, Morisita index, k index, Green coefficient and Taylor potency. The rice stem bug spatial arrangement has been validated when the dispersion indices showed similar results. The rice stem bug T. limbativentris spatial arrangement in flooded rice is the aggregate type, regardless of the infestation level and life stage of the insect.
