First detection of Scirtothrips dorsalis in the Valencian Community

Given the damage caused by thrips observed since May on leaves and fruit in various citrus, persimmon and pomegranate crops and the confirmation of the presence of Scirtothrips aurantii Faure in certain areas, the following recommendations have been considered appropriate:

This document sets out the measures to be taken against the quarantine pest Scirtothrips aurantii Faure, with the aim of preventing its appearance and, if it does appear, acting quickly and effectively, determining its distribution and combating it in order to try to eradicate it and prevent its spread at all times.

This document outlines the measures to be taken against Elsinoë fawcettii, a regulated harmful organism, with the aim of preventing its emergence and, if it does, responding quickly and effectively, determining its distribution, and implementing eradication measures. Elsinoë fawcettii is a fungus of the Ascomycota phylum and the Elsinoaceae family that causes the disease citrus scab.

A sucking insect belonging to the Triozidae family. Commonly known as the African citrus psyllid, it is native to sub-Saharan Africa. It is widely distributed in Africa and to a limited extent in the Middle East and Europe. It was detected in Spain in 2002, in the Canary Islands, and in 2014 in the Iberian Peninsula, Galicia, and northern Portugal.

On February 12, 2019, a "Seminar on Xylella fastidiosa" was held in the Assembly Hall of the Ministry of Agriculture, Fisheries, and Food. This seminar is part of the measures adopted by the Ministry to disseminate information and raise awareness about the fight against and control of Xylella fastidiosa.

HBL is the most devastating incurable bacterial disease of citrus, transmitted through grafts of contaminated trees and through insect vectors such as Trioza erytreae.

Xylella fastidiosa (Wells et al.) is a quarantine phytopathogenic bacterium that has a very wide range of host plants (more than 300 plant species), and can cause serious damage to the most important crops of the Balearic Islands, such as almond, vine, olive, citrus or fig trees, and to numerous species of ornamental plants (rosemary, lavender, polygala and acacia, among others).

This document outlines the measures to be taken against non-European tephritid species (non-European fruit flies) with the aim of preventing their emergence. Should any of the species mentioned in this National Contingency Plan appear, it is necessary to act quickly and effectively, determine their distribution, and combat them to prevent their spread.

Scirtothrips aurantii is a pest that affects various crops such as pomegranates, persimmons, citrus fruits, and table grapes. This pest was first detected in Spain in 2020, in the province of Huelva.

The California red scale (Aonidiella aurantii) is one of the pests that most concerns the citrus sector in the Valencian Community since it depreciates the fruit's rind and, having several generations per year, reproduces exponentially throughout the campaign.

Whiteflies are the pests that have most concerned both the persimmon and citrus production sectors in the Valencian Community in recent years. Within this group of insects, the species most commonly found are Dialeurodes citri, Paraleyrodes minei, and Aleurothrixus floccosus.

Citrus gummosis, caused by Phytophthora spp., affects the trunk and main branches of the variety (Figs. 1a and 1b). As its name suggests, it is characterized by the abundant appearance of gum on the affected tissues. If we remove the bark, we can see the internal tissues of the phloem and cambium, which have a very characteristic brown color and watery appearance (Fig. 1b).

Pulvinaria polygonata (Cockerell) is a coccid from the Coccidae family that was found in citrus groves in the Vega Baja del Segura region in 2019, marking the first record in Europe. It is present in other regions of the world, such as Australia, the East, and some countries in the eastern Palearctic zone (China, Japan, and Taiwan).

This document sets out the measures to be taken against the bacterium Xylella fastidiosa, a priority Union quarantine pest, with the aim of preventing its emergence and, if it does appear, acting quickly and effectively, determining its distribution and implementing eradication measures.

Trioza erytreae is a pest regulated in the European Union (EU) by Commission Regulation 2019/2072 and is a major vector of the bacterium that causes Huanglongbing (HLB) or citrus greening. HLB, itself a regulated organism in the EU, deteriorates the quality and flavor of the fruit and can kill the affected tree within a few years.

This document sets out the measures to be taken against the African Citrus Psyllium insect, Trioza erytreae (Order: Hemiptera, Superfamily: Psylloidalea, Family: Triozidae), a pest included in the Union's list of quarantine pests by Regulation 2019/2072 and vector of the bacteria that causes Huanglongbing (HLB) or citrus greening.

This document sets out the measures to be taken against the bacterium Xanthomonas citri (pathovars citri and aurantifolii), a quarantine pest, which causes citrus canker, with the aim of preventing its appearance and, if it does appear, acting quickly and effectively, determining its distribution and combating it in order to prevent its spread and eradicate it.

This document sets out the measures to be adopted against Thaumatotibia leucotreta (codling moth), a pest regulated by the EU as a priority quarantine pest under Implementing Regulation (EU) 2019/2072 and Delegated Regulation (EU) 2019/170.

This document outlines the measures to be taken against Candidatus Liberibacter spp., bacteria associated with the disease known as Huanglongbing (HLB), or greening, a quarantine organism regulated in the European Union (EU). HLB is considered the most important, serious, and destructive citrus disease worldwide.
