Autores: Pimentel,Marco A G; Faroni,Lêda R D'A; Silva,Felipe H da; Batista,Maurílio D; Guedes,Raul N C.
The resistance to fumigant insecticides in stored-products insects is often recorded. Several factors influence the evolution of insecticide resistance. Among these, the frequency of applications and the migration of resistant populations are of primary importance for the stored-product insects. The aim of this study was to characterize the spectrum and investigate the status of phosphine resistance in Brazil, in 13 populations of the Coleoptera Tribolium castaneum Herbst (Tenebrionidae), ten populations of Rhyzopertha dominica (Fabr.) (Bostrichidae), and eight populations of Oryzaephilus surinamensis (L.) (Silvanidae). The pattern of resistance dispersion in the populations of these species was also verified. The bioassays for the detection of phosphine...

RESUMO Avaliou-se a influência dos danos físicos causados pelo processo de colheita sobre a infestação por Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) no grão de milho armazenado. Duas variedades de milho, de consistência semi-dura e dura, foram colhidas manual e mecanicamente, com teores de umidade de 20,5 e 15,5%; amostras desse material foram infestadas e, após, armazenadas. O desenvolvimento de T. castaneum foi avaliado por meio da taxa de crescimento populacional no período. Não houve diferenças significativas entre colheita manual e mecânica, entre as variedades semi-dura e dura; nem entre as umidades na colheita de 20,5 e 15,5%, exceto na colheita mecanizada da variedade semi-dura que, com 20,5% de umidade, apresentou maior percentual...

Autores: Conceição,Patrícia M. da; Faroni,Lêda R. A.; Sousa,Adalberto H.; Pimentel,Marco A. G.; Freitas,Romenique S.
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...

Biological activity and persistence of pirimiphos-methyl applied to maize grain at different temperatures
Provedor de dados: 91
Autores: Silveira,Rodrigo D.; Faroni,Lêda R. A.; Guedes,Raul N. C.; Queiroz,Maria E. L. R.; Pimentel,Marco A. G.
The expansion of dryeration may impose a further problem for insect control with protectants - the high grain temperatures during insecticide spraying. To assess the impact of this procedure on insecticide activity, maize grains at different temperatures (25, 30, 35, 40 and 45 °C) were sprayed with pirimiphos-methyl. Residue analyses were carried out every 30 days and insecticide biological activity towards Sitophilus zeamais and Tribolium castaneum was assessed every 15 days throughout the experimental period of 90 days. Insect mortality was evaluated after 48 h. Pirimiphos-methyl residue decreased with increased storage time and grain temperature during spraying. Similar trends were also observed for mortality of S. zeamais and T. castaneum, which...

Provedor de dados: 99
Autores: Lancelle,Hugo G.; Giordano,Oscar S.; Sosa,Marta E.; Tonn,Carlos E.
Toxic and repellent properties of whole essential oils from four Eupatorium (Asteraceae) species (E. buniifolium Hook. et Arn, E. inulaefolium Kunth, E. arnottii Baker, and E. viscidum Hook. &amp;amp; Arn) were investigated in different concentrations toward Tribolium castaneum Herbst adults. The essential oils were isolated by hydrodistillation techniques from the aerial parts. The analysis was performed by GC-FID and GC-MS methods. Contact toxicity assays showed that all the evaluated essential oils were toxic. Furthermore, in all the cases mortality was dose dependent. The main repellency was observed for the essential oil recovered from E. buniifolium.

ABSTRACT  Nanobiotechnology deals with the properties of nanomaterials and their potential uses. Here we report for the first time novel, cost-effective and eco-friendly method for the rapid green synthesis of silver nanoparticles (AgNPs) using leaf extracts of Myriostachya wightiana. The growth of silver nanoparticles was monitored by UV-vis spectroscopy complemented by Zeta potential, dynamic light scattering technique (DLS), Fourier-transform infrared spectroscopy (FTIR), Transmission electron microscope (TEM) and X-ray diffraction (XRD). The surface plasmon resonance (SPR) band found at 434 nm confirmed the reduction of AgNO3 to AgNPs. TEM micrographs revealed that AgNPs are irregular in shape with the size range from 15-65 nm. The functional groups...
