| As doenças pós-colheita são fatores limitantes para estocagem e exportação de mamão e é crescente o interesse por métodos alternativos de controle. O tratamento hidrotérmico tem se mostrado como método promissor podendo ser integrado a outros. O objetivo deste trabalho foi verificar o efeito in vitro do tratamento térmico nos principais fungos causadores de podridão na pós-colheita do mamão: Fusarium solani, Alternaria alternata, Colletotrichum gloeosporioides, Phoma caricae-papayae e Lasiodiplodia theobromae, bem como determinar os binômios temperaturas e tempos letais de cada um deles. Discos de micélio foram colocados em bolsas de gaze simples e estéril, depois foram imersas em água destilada estéril em um balão de três bocas contendo um agitador e um... |

| ABSTRACT Corn is a cereal whose productivity can be reduced by various diseases which has recommended treatments for control. The objective of this study was to analyze copper, zinc, calcium and manganese products for the management of Pantoea ananatis, Puccinia polysora and Cercospora zeae maydis in second season corn, and interference in agronomic characteristics. Commercial products made of amino acid chelated with 15% calcium, 5% copper, 15% manganese and 10% zinc, at the doses of 0.5 kg ha-1, 0.3 L ha-1, 0.4 kg ha-1 and 1 L ha-1, respectively, a treatment with fungicide (20% azoxystrobin and 8% cyproconazole at 0.3 L ha-1 + 25% propiconazole at 0.4 L ha-1), and a treatment with water were assayed. The experiments were carried out under field... |

| The white mold, caused by Sclerotinia sclerotiorum, is a very important disease in tomato crops. The objective of this work was to study the effect of plant extracts, animal residues and industrial by-products extracts on the fungus in vitro growth. Treatments consisted of different concentrations of pyrolignous oil, neem oil, monosodium glutamate, sewage sludge and organic compost [coffee residue (50%) coal residue (10%), maize residue (25%), poultry waste (12.5%), poultry meal (2.5%)]. Positive control consisted of Petri dishes with PDA medium and negative control treatment consisted of PDA medium with procymidone. Fungus colonies were incubated at 22ºC and light intensity of 260 lux. Variables such as mycelium growth rate, sclerotia production, and... |

| The goal of this research was to compare the effect of the following products on dairy cattle, parasitized by Rhipicephalus microplus: organosynthetics - Clorfenvinfós and Ivermectina (OG); phytotherapics - Eucalyptus oil (EG) and Neem cake (NG); Homeopathy (HG); The control group (CG) received no treatment. Infestation was by R. microplus (MIC) and weight gain (GP) were evaluated. The study included 60 animals (5 groups) from ¾ Dutch / Zebu, aged between 25-44 months and initial weight between 211-477kg. EG and NG showed MIC 84.9% and 14.0% greater than CG, respectively (P <0.05; P = 0). HG and OG had MIC less than CG 24.4% and 16.9%, respectively (P<0.05; P <0.05). EG, NG and OG obtained GP lower than CG in 7.9%, 8.9% and 8.06% (P <0.05)... |

| Resumo: Este trabalho teve como objetivo determinar a atividade de peroxidases em frutos de mamão submetidos aos tratamentos físicos em pós-colheita, hidrotérmico e ozônio, aplicados individualmente e combinados, durante 8 dias de armazenamento. Um lote de 102 frutos de mamão do grupo Solo, proveniente de uma lavoura comercial, sem tratamento na pós-colheita, foi submetido aos tratamentos hidrotérmico (70ºC/15s), ozônio (1,5 ppm), aplicados tanto individualmente quanto combinados. Frutos não submetidos aos tratamentos físicos configuraram como controle. Após os tratamentos, os frutos foram mantidos durante 7 dias em câmara fria (10 ± 2ºC e 80 ± 2% de umidade relativa) e 1 dia em condição ambiente (23 ± 2ºC). Para a determinação da atividade de peroxidases,... |

| The present study intended to analyze calliphorid attraction to traps painted in a variety of colors and the calliphorid constancy index in the Tingua Biological Reserve, Rio de Janeiro state, Brazil. The Diptera were collected monthly in the Reserve, between 2002 and 2005, totaling 24 samplings. Four traps containing sardines as bait were painted olive green, blood red, black, or white and exposed for 48 h at four equidistant points, 50 m from each other. To determine the calliphorid species constancy, the Bodenheirmer constancy index was used throughout the study. To analyze differences in the total abundance between species and in their color selection, an ANCOVA test with a significance level of 5 % and a Tukey post-test were used, considering the... |

Camarosa. In vitro condition two experiments were conducted, being mycelial growth and conidia germination in a factorial 4 X 5, with factors extraction modes and extracts concentrations (0, 3, 6, 9 e 12%), with four replicates. Post-harvest were tested four types of extracts at a concentration of 16%. The design was completely randomized, with four replicates per treatment, and the portion composed of 10 fruits per replicate. Physichocemical parameters and biochemical analyzes were evaluated.

| ABSTRACT Besides their value as therapeutic resources, medicinal plants may also be used as sources of active ingredients against phytopathogens. Fungi can grow and cause spoilage in food, thus, resusting in decrease in its quality and quantity. This research aimed at evaluating the effect of essential oil from Murraya paniculata (ML-EO) leaves on mycelial growth of Sclerotinia sclerotiorum, a fungus that poses high risk to several cultures, mainly soybean. Essential oil from M. paniculata (Rutaceae) leaves was obtained by hydrodistillation which was carried out by a Clevenger-type apparatus while its chemical composition was analyzed by GC-FID and GC-MS. β-Caryophyllene (23.8%), α-zingiberene (21.0%) and β-cubebene (10.2%) were the main constituents... |

| Abstract: The objective of this work was to evaluate the commercial formulations of Bacillus subtilis QST-713 and Bacillus pumilus QST-2808 on mycelial growth inhibition of Thielaviopsis paradoxa, for the control of the pineapple disease and growth promotion in sugarcane. The inhibition of mycelial growth was evaluated in paired culture tests. Bacillus isolates were transferred to Petri dishes 48 hours before the pathogen, and the zone of inhibition was determined. The direct effect of the autoclaved commercial formulations at 0, 0.001, 0.01, 0.1, 1.0, and 10.0% on the inhibition of pathogen mycelial growth was evaluated. Bacillus spp. potential in controlling the disease and promoting plant growth was evaluated in assays on plant development and disease... |

| Se estudió el efecto del extracto oleoso de neem (A. indica) en el control de V. destructor. La investigación estuvo encaminada a explorar los efectos que causa el neem tanto a V. destructor como a Apis mellifera, donde la colonia de abejas se observó como un superorganismo. En la primera parte de la investigación se corroboraron en laboratorio los efectos de toxicidad y repelencia del neem en el ácaro, observados en estudios previos; se observó que 2.64, 5.28, 10.56 y 21.12% de extracto de neem presentaron alta estabilidad en cuanto al efecto repelente; y 21.12% impidió que 98% de las varroas se posaran sobre pupas de abejas, lo que llevó a 100% de mortalidad de varroa en 72 h. La segunda etapa estuvo orientada a determinar los efectos del neem sobre... |

| The aim of this study was to evaluate the insecticide activity of diatomaceous earth (DE), at different temperatures, on two populations of Tribolium castaneum and Rhyzopertha dominica previously diagnosed as resistant and susceptible to phosphine. The efficiency of DE in the control of the insects was evaluated at temperatures of 20, 25, 30, 35 and 40 ± 2 ºC. The experiments were accomplished in Petri dishes containing 35 g of whole-wheat grain treated with DE in the dose of 1.0 kg t-1. The control was constituted by untreated wheat grain. Each Petri dish was infested with 30 adult insects. Insect mortality was registered seven days after the beginning of the bioassays. The experiment was conducted in a completely randomized design with three... |

| RESUMO: Várias doenças acometem a manga na fase de pós colheita, mas a antracnose (Colletotrichum gloeosporioides Penz.) é a mais importante. O controle dessa doença tem sido feito pela imersão dos frutos por cinco minutos em água a 55 °C contendo 0,2 % de tiabendazol. Embora seja eficaz no controle dessa doença, esse fungicida pode deixar resíduos indesejáveis aos consumidores cada vez mais exigentes por frutos ambientalmente limpos e livres de resíduos agroquímicos. Os experimentos foram conduzidos para selecionar produtos biológicos e químicos para controlar a antracnose e aumentar o tempo de conservação da manga na pós colheita. Os frutos, colhidos no estagio de maturação 3 e 4, foram imersos por cinco minutos em tiabendazol a 0,24%, benomil a 0,1% a... |
