| El objetivo del presente trabajo fue identificar y caracterizar la fluctuación y densidad poblacional de tres especies vectoras del virus Citrus leprosis virus-C (CiLV-C) en los estados de Yucatán, Campeche y Quintana Roo, para su eventual aplicación en el desarrollo de sistemas de muestreo en programas oficiales de detección en México. Durante el período de febrero 2010 a febrero 2011, se realizaron ocho muestreos en 100 árboles/parcela. Se obtuvieron muestras de Citrus sinensis, C. aurantium, C. reticulata, C. latifolia, C. paradisi y C. reticulata x C. sinensis. La identificación de las especies de Brevipalpus spp. se realizó con preparaciones de ácaros montados en líquido de Hoyer y observaciones con microscopio electrónico de barrido. La determinación... |

| Despite the importance of citriculture in Brazil, very little is known about mite populations in citrus crops in the Northern Region. In the municipality of Manaus, 12 sprayed sweet orange orchards were surveyed every two weeks during seven months to record mite species amount, and to describe the abundance and distribution of the most important species. The size and age of the orchards varied from 3,360 to 88,080 m² and seven to 25 years, respectively. In the fourteen sampling period, leaves, twigs and fruits were collected from 12 trees, one per orchard. In total, 3,360 leaves, 672 twigs and 1,344 fruits were sampled from 168 trees. Mites were manually extracted from the fruits, and by the washing method on leaves and twigs. We identified pests with the... |
