Conteúdo:  Knockdown (kdr) resistance is caused by a reduction in the sensitivity of the arthropod nervous system to pyrethroids. Kdr resistance in field populations of cattle tick can severely limit pyrethroid usefulness in tick control programs. Early detection and characterization of kdr resistance are critical to the development of resistance management strategies. Cattle tick samples collected in Porto Velho and Presidente Medici, Rondonia were analyzed at Knipling-Bushland U.S. Livestock Insects Research Laboratory, USDA/ARS, Kerrville, TX, to verify the genotypes of these cattle tick populations. First, the populations were assessed using commercial cypermethrin solution by Adult Immersion Test (AIT) conducted at Embrapa Rondonia Animal Health Laboratory. Engorgement females ticks were exposed for 30 minutes in commercial cypermethrin solution prepared according to the manufacturer recommendations. The control group was formed with engorged females cattle ticks belonging to each of the populations tested, which were immersed in distilled water. Three groups of ten ticks were used in each treatment. Ten females by Presidente Medici population and three females by Porto Velho population immersed in commercial cypermethrin solution survived. The survived females were placed in B.O.D to obtain the postures. After the eggs hatch, the larvae were collected and immediately frozen at ultra-low temperature.Genomic DNA was isolated from individual larvae cattle tick and 30 larvae of each ... Mostrar Tudo

Título:  Degree of phosphorus saturation threshold for minimizing P losses by runoff in cropland soil of Southern Brazil.
Ano de publicação:  2016

Idioma:  Inglês
Conteúdo:  The objective of this work was to assess the risk of phosphorus losses by runoff through an index based on the degree of P saturation (DPS), in cropland soils of Southern Brazil. Sixty-five highly representative cropland soils from the region were evaluated. Three labile P forms were measured (Mehlich-1, Mehlich-3, and ammonium oxalate), and four P sorption indexes were tested (phosphorus single sorption point and Fe+Al determined with the three extractors). Water-extractable P (WEP) was used as an index of P susceptibility to losses by surface runoff. The DPS was determined from the ratio between labile P and each sorption index. DPS values obtained from the ratio between Mehlich-1 P and the single P sorption point ranged from 1 to 25%, whereas those from Mehlich-1 P and Fe+Al (ammonium oxalate) ranged from 1 to 55%. All DPS types were highly correlated with WEP. From a practical stand point, the DPS obtained with both P and Fe+Al extracted with Mehlich-1 can be used to estimate the risk of P losses by runoff in soils of Southern Brazil.
