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... |

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... |

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... |
