Primer reporte del enrollador de bandas oblicuas, choristoneura rosaceana (harris) (lepidoptera: tortricidae), en manzano en el ejido Vista Hermosa, Ciudad Cuauhtémoc, Chihuahua, México

Choristoneura rosaceana (Harris) is recorded for the first time in apple crops variety ‘Golden Delicious’ in the Ciudad Cuauhtémoc, Chihuahua, Mexico. Immature stages were described briefly and its damage in foliage and fruits; also the adults main characteristics. The way of arrivalby this pest to the apple crops region was hypothesized

Characterization of a Proposed Dichorhavirus Associated with the Citrus Leprosis Disease and Analysis of the Host Response

The causal agents of Citrus leprosis are viruses; however, extant diagnostic methods to identify them have failed to detect known viruses in orange, mandarin, lime and bitter orange trees with severe leprosis symptoms in Mexico, an important citrus producer. Using high throughput sequencing, a virus associated with citrus leprosis was identified, belonging to the proposed Dichorhavirus genus. The virus was termed Citrus Necrotic Spot Virus (CNSV) and contains two negative-strand RNA components; virions accumulate in the cytoplasm and are associated with plasmodesmata—channels interconnecting neighboring cells—suggesting a mode of spread within the plant. The present study provides insights into the nature of this pathogen and the corresponding plant response, which is likely similar to other pathogens that do not spread systemically in plants
