Since 1992, anthracnose of Andean blackberry (Rubus glaucus) has generated losses as high 40% for farmers in Colombia. In this study, our goal was to characterize 240 Colletotrichum isolates from eight areas These were evaluated according morphological characteristics, sensitivity benomyl, pathogenicity, and genetic variability. Identification the genus achieved by using species complex-specific polymerase chain reaction primers. A multilocus phylogeny approach used identify level with...
The strain Purpureocillium sp. UdeA0106 is an antagonist of nematodes, fungi, and garden symphylans from crops with high economic importance in Colombia (Salazar Citation2013; Salazar et al. Citation2014; Cardona Gallego Citation2014) being studied to be proposed as new species. It was included on the 1000 fungal genomes project elucidate its phylogenetic relationships other fungi. Purpureocillium's mitogenome has 23,495 bp circular size. contains 15 protein-coding genes without duplications...
Introduction. Aedes aegypti is an important vector of arboviral diseases like dengue among others. Traditional control strategies, such as the use insecticides, have lost effectiveness due to emergence resistance in mosquito populations. Biological and fungi applied for biocontrol are presented viable ecological alternatives. Objective. To evaluate vitro pathogenicity Trichoderma sp. isolates obtained from Urabá (Antioquia) on larvae Ae. aegypti, determine mean lethal concentration time most...
Resumen Introducción: Aedes aegypti, originario de África, se ha extendido globalmente, siendo el principal vector del dengue en Colombia. El uso repetido insecticidas generado resistencia estos mosquitos, impulsando la búsqueda estrategias complementarias. Objetivo: Este estudio propuso evaluar potencial hongo Trichoderma asperellumaislado municipio Virgina (Risaralda Colombia) como agente biocontrolador Ae. aegypti. Metodología: Los bioensayos in vitro realizaron con larvas expuestas a una...
In Colombia, the Tetranychus urticae mite (Acari: Tetranychidae) is one of most challenging phytosanitary issues faced by flower cultivators. The control this has been commonly done through use chemical insecticides. But mites have generated resistance to these substances over time, making their handling more difficult. Some sustainable alternatives based on biological agents (BCA) can also be implemented in T. urticae. fungus Akanthomyces lecanii proved effective urticae, however,...
Colombia is recognized as an important agricultural producer of pineapple and flowers. One the most significant phytosanitary problems these crops pathogenic nematodes it necessary to find biocontrol alternatives for their management. This study evaluated effect Purpureocillium sp., strain UdeA0106, over number nematodes. Soil from flower was collected on expanded polystyrene containers suspension fungi multiplied in a bioreactor (1x108 conidia/mL), then homogenized finally applied. The...
Introducción: Los estudios sobre las alteraciones morfo-anatómicas e histoquímicas ocasionadas por la Oidiosis o ceniza en hojas de Hydrangea macrophylla son escasos literatura científica. Objetivos: describir y analizar aspectos anatómicos histopatológicos este patosistema. Métodos: se tomaron más 90 H. sanas infectadas que recolectaron el vivero El Jardín del Edén, Rionegro, Antioquia-Colombia. Para identificación micopatógeno, secciones obtenidas tiñeron con azul Lactofenol consultaron...
