ABSTRACT
Livestock farming based on pasture monocultures is associated with negative environmental impact and soil erosion. An alternative to counteract these effects is the implementation of silvopastoral systems (SSP). These, in their grass/shrub-tree/animal interaction, increase productive potential and raise the nutritional value of forages. Cu...
El cultivo del plátano (Musa spp.) se ve afectado por diversas enfermedades que disminuyen el rendimiento y calidad. La Sigatoka negra (Pseudocercospora fijiensis) es el principal problema fitopatológico en este cultivo, por lo que se estudió la sensibilidad de P. fijiensis a cinco fungicidas sistémicos (Tebuconazol, Bitertanol, Pirimetanil, Triflo...
In Mexico, the Oesophagostomum dentatum is considered one of the main gastrointestinal endoparasites affecting the most important breed in rural pig farming, the hairless pig [Cerdo Pelon Mexicano (CPM)]. In this research, it was evaluated the in vitro biological efficacy of vegetable extracts of ginger, mint, thyme and oregano, with the aim of fin...
In Mexico, bullfrog (Lithobates catesbeianus) production is carried out in only 35 animal production units, and improvements in its commercialization are necessary to increase demand. Faced with these challenges, innovative technological options such as Biofloc are emerging, which improve production efficiency in favor of environmental, economic an...
El frijol y el tomate en México son dos de los productos que forman parte esencial de la dieta de la población de este país, es de gran importancia económica, cultural y gastronómica. La presencia de plagas y enfermedades en los cultivos aumenta los costos de producción, además del impacto ambiental y la residualidad de los plaguicidas pueden afect...
Tenebrio molitor y Gromphadorhina portentosa fueron comparados como posibles fuentes alternativas de proteína para consumo animal, con harina de pescado y harina de soya. La proteína cruda de las harinas obtenidas de los insectos fluctuó 51 al 69% (metodología de Dumas), las grasas del 4 al 22% (metodología de Goldfish). La digestibilidad de la mat...
Beauveria bassiana (Bals.-Criv.) Vuill. and Metarhizium anisopliae (Metchnikoff) Sorokin were autodisseminated in the house fly, Musca domestica L., when one, five, and 10 virgin, 3-day old males exposed to 6 × 108 conidia ml-1 per fungus were confined with 30 females of the same age. Fungal treatments with one or five males killed few, with LT50 o...
El objetivo del estudio fue evaluar los efectos de línea genética (LG), número de parto (NP) y sala de parto (S) en el tamaño de la camada nacida viva (TCNV), el número de lechones nacidos muertos por camada (LNM), e l tamaño de la camada al nacimiento (TCN) y al destete (TCD), los pesos de la camada al nacimiento (PCN) y al destete (PCD), el consu...
Background & objectives:
Aedes albopictus has been known as efficient vector of dengue in Asian countries and its wide displacement of Ae. aegypti has been documented in many parts of the world. The present survey was carried out to update the distribution of Ae. albopictus in northeast Mexico and to report the first record of parasitism of mosqui...
Background Resistance to chemical insecticides plus high morbidity rates have lead to rising interest in fungi as candidates for biocontrol
agents of mosquito vectors. In most studies fungal infections have been induced by exposure of mosquitoes to various surfaces
treated with conidia. In the present study eight Mexican strains of Beauveria bassia...
Se estudió el efecto de incluir el coeficiente de consanguinidad del animal (F) en los modelos para la evaluación genética de bovinos mexicanos Jersey y Suizo Americano de registro. El modelo sin el efecto de consanguinidad que incluyó el efecto fijo de hato-año-estación y los aleatorios genético directo y de ambiente permanente, se comparó con otr...
The inclusion of the inbreeding coefficient (F) into the models to predict breeding values (BV) for Jersey (J) and Brown Swiss (BS) Mexican registered dairy cattle was studied. The conventional model including the fixed effect of herd-year-season, and the genetic additive and permanent environmental random effects was compared to an alternative mod...
Dengue is a viral disease transmitted by Aedes mosquitoes. It is a threat for public health worldwide and its primary vector Aedes aegypti is becoming resistant to chemical insecticides. These factors have encouraged studies to evaluate entomopathogenic fungi against the vector. Here we evaluated mortality, infection, insemination and fecundity rat...
Resistance to chemical insecticides plus high morbidity rates have lead to rising interest in fungi as candidates for biocontrol agents of mosquito vectors.
