Pest categorisation of Nemorimyza maculosa

EFSA Journal, Volume 18, Issue 3, March 2020., 2020
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Nemorimyza maculosa (Malloch) (Diptera: Agromyzidae) for the European Union (EU). N. maculosa is an oligophagous pest; cultivated hosts include Chrysanthemum, lettuce and other Asteraceae although there is little evidence of recent impacts. N.

Polyclonal antibodies to the putative coat protein of Citrus leprosis virus C expressed in Escherichia coli: production and use in immunodiagnosis [PDF]

Tropical Plant Pathology, 2013
This work reports the in vitro expression of Citrus leprosis virus C (CiLV-C) putative coat protein (p29) and the production of a polyclonal antibody to be used as a tool for serological diagnosis of citrus leprosis. The ORF2/RNA1, corresponding to p29, was cloned in pET28a and transformed into Escherichia coli cells (BL21).

Pest categorisation of Liriomyza sativae

EFSA Journal, Volume 18, Issue 3, March 2020., 2020
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Liriomyza sativae (Diptera: Agromyzidae) for the EU. L. sativae (the cabbage or vegetable leaf miner; EPPO code: LIRISA) is a polyphagous pest native to the Americas which has spread to Africa, Asia and Oceania. L. sativae can have multiple overlapping generations per year. Eggs

Common Bean: Experimental Indicator Plant for Citrus leprosis virus C and Some Other Cytoplasmic-Type Brevipalpus-Transmitted Viruses [PDF]

Plant Disease, 2013
Citrus leprosis (CL) caused by Citrus leprosis virus C (CiLV-C) is present in Latin America from Mexico to Argentina, where citrus plants are grown. CiLV-C is transmitted by the tenuipalpid mite, Brevipalpus phoenicis, causing localized lesions on citrus leaves, fruit, and stems.

Citrus leprosis virus C Naturally Infecting Commelina benghalensis, a Prevalent Monocot Weed of Citrus Orchards in Brazil

Plant Disease, 2012
There are two bacilliform, rhabdo-like viruses that cause citrus leprosis: Citrus leprosis virus C (CiLV-C), which accumulates in the cytoplasm of infected cells, and Citrus leprosis virus nuclear type (CiLV-N), which accumulates in their nucleus. The first one, the prototype of the new genus Cilevirus, is prevalent and occurs in several countries of ...
