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

CITRUS LEPROSIS IN FLORIDA, USA, APPEARS TO HAVE BEEN CAUSED BY THE NUCLEAR TYPE OF CITRUS LEPROSIS VIRUS (CiLV-N)

VIRUS Reviews & Research, 2011
Citrus leprosis (CL) is a highly destructive viral disease vectored by Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae). It was first described in Florida in 1907 and last reported in 1968. CL was found after the 1920s in South America (Paraguay, Argentina and Brazil) and presently is known to occur in most of the South American countries.

Transmission of Citrus leprosis virus C by Brevipalpus phoenicis (Geijskes) to Alternative Host Plants Found in Citrus Orchards [PDF]

Plant Disease, 2012
The equivalent of US$75 million is spent each year in Brazil to control Brevipalpus phoenicis, a mite vector of Citrus leprosis virus C (CiLV-C). In this study, we investigated the possibility that hedgerows and windbreaks normally found in citrus orchards could host CiLV-C.
