German Express PRA on Thekopsora minima, Blueberry Rust

German Express PRA on Thekopsora minima, Blueberry Rust | Pest risk analysis | Scoop.it

JKI recently published an Express PRA (in German) on Thekopsora minima after a finding of this pathogen on plants of blueberry (Vaccinium corymbosum) in a nursery in Lower Saxony. 

Hosts include blueberry Vaccinium corymbosum as well as rhododendrons, azaleas and various other ericaceae.

The phytosanitary risk for the Germany and the EU is considered high and the PRA recommend that phytosanitary measures to prevent entry should be taken.

Dutch Quickscan on Singhiella simplex, ficus whitefly

This Quickscan was conducted after the interception of the fig white fly species Singhiella simplex (Hemiptera: Aleyrodidae) on Ficus plants originating from Costa Rica. The species is a serious pest of ornamental Ficus plants but is not known as a pest of Ficus carica that is grown for its fruit. The pest is especially a risk for Ficus plants grown outdoors in southern Europe. The species appear to spread over the world probably as a consequence of trade as it has been reported from several continents outside its native origin. It has recently been found in the EU (on Cyprus) and no statutory action was taken against it. In glasshouses in northern Europe, the species may be controlled and even eradicated by application of insecticides.

Risks to plant health posed by EU import of soil or growing media

Risks to plant health posed by EU import of soil or growing media | Pest risk analysis | Scoop.it

Following a request from the European Commission, in this scientific opinion the EFSA Panel on Plant Health evaluates the risk of entry into the European Union of harmful organisms associated with soil or growing medium attached to plants for planting, as commodities, and as contaminants on imported consignments.

From the soil and growing media and/or components thereof identified through extensive literature searches, the Panel distinguished eight groups of soil and growing media and assessed the probability of association of these groups with harmful organisms. A total of 207 scientific publications were reviewed by the Panel in order to identify and rate the effectiveness of options that could reduce the risk of entry of pests posed by the import of soil and growing media. A detailed description and evaluation of the requirements for soil and growing media laid down in current EU legislation on plant health and in a few other regions of the world is provided. The Panel found that the ‘prohibition of import’ is the only phytosanitary measure with a very high effectiveness and a low uncertainty. The effectiveness of the phytosanitary measures ‘pest free production site and preparation of consignment’ is rated as moderate to high with an uncertainty rated as medium to high. Although several phytosanitary measures in these categories of risk reduction options could be highly effective, EU legislation does not provide clear formulation and guidance on their implementation.

UK PRA on Platynota stultana

Platynota stultana is a polyphagous tortricid moth, native to  North America. Recently, it has been detected further afield, in Hawaii and in Spain, both in glasshouses and the wider environment. Although unlikely to survive outdoors in the UK, establishment in protected cultivation is considered likely if the pest were to be introduced to UK production facilities via a pack house on imported produce.

Due to the presence of this species in Spain and the fact that it could be associated with so many plants, statutory measures against entry of P. stultana would best be met by requirements for pest free areas or pest free production sites.

Continued monitoring of developments in Spain where the pest is present will inform consideration on whether EU regulation is warranted.Surveillance with pheromone traps and raising awareness with the industry may help to identify incursions.

UK Express PRA for Xylosandrus crassiusculus (Coleoptera: Scolytinae)

UK Express PRA for Xylosandrus crassiusculus  (Coleoptera: Scolytinae) | Pest risk analysis | Scoop.it

This rapid PRA shows that X. crassiusculus is a highly damaging pest in much of its current range with the potential to continue to spread and become introduced to new areas in Europe.

Entry is likely on raw wood products, including timber and other unprocessed woods products, moderately likely on wooden packaging material and unlikely on planting material and cut branches. Though entry very natural spread to the UK is very unlikely, risk of continued natural spread in the EU is high.

Sirococcus tsuga added to the EPPO Alert List

Sirococcus tsuga added to the EPPO Alert List | Pest risk analysis | Scoop.it

Sirococcus tsugae is a recently described fungal species which was recorded for the first time in Germany in 2014. Previously, S. tsugae was only known to occur in North America. This new species was described following studies on isolates previously regarded as Sirococcus conigerus. In these studies, three distinct species could be identified: Sirococcus conigerus (sensu stricto, occurring in Europe and North America on various conifers), Sirococcus tsugae (isolates from Cedrus and Tsuga in Western North America), Sirococcus piceicola (isolates from Picea in Canada and Switzerland). These recent taxonomic changes render the geographical distribution, host range, and biology difficult to ascertain. However, the Panel on Phytosanitary Measures considered that this fungus could usefully be added to the EPPO Alert List, even with a minimal amount of data.

Muriel Suffert's insight:

EU-project DROPSA: first achievements regarding pathway analyses for fruit pests

EU-project DROPSA: first achievements regarding pathway analyses for fruit pests | Pest risk analysis | Scoop.it
The EU project ‘DROPSA’ started in 2014 and aims to improve plant health strategies in the fruit sector. The project is being conducted by an international consortium of 26 partners consisting of phytosanitary organizations, companies, research institutes and universities and will last 50 months. Results will be disseminated via conventional publications and will be brought together in the development of risk-based strategies to prevent the introduction of new fruit pests. This article describes the task related to the preparation of alert lists of pests that may be introduced into Europe with the trade of fruit. Activities of this task include the investigation of pathways of introduction for fruit pests into Europe, the development of alert lists for selected fruit crops and a review of current legislation. A review of introductions, interceptions and outbreaks that occurred during the last 10–15 years was conducted and is summarized, showing the relevance of fruit trade for the international movement of pests. Work has started on the development of alert lists for selected pathways. In this context, important fruit crops (including Malus, Vaccinium, Vitis, Citrus) were selected.

Phytosanitary inspection of woody plants for planting at European Union entry points: a practical enquiry

Phytosanitary inspection of woody plants for planting at European Union entry points: a practical enquiry | Pest risk analysis | Scoop.it

Phytosanitary import inspections are important to avoid entry of harmful pests on live plants. In the European Union (EU), all consignments of live plants must be inspected at the first point of entry, and plants allowed entry can be moved without further inspection among the 28 Member States and Switzerland. It is important that inspections in EU countries adhere to the same standard to avoid introduction of harmful organisms through countries with weaker methods. We tested whether sampling intensity and confidence in the inspection results were the same across these countries. Questionnaires were sent to inspectors in all countries, asking about inspections of individual consignments of woody plants for planting. Data about 102 lots, inspected at 13 points of entry in six countries, were analyzed. We used hypergeometric and binomial statistics for small and large consignments, respectively, to calculate the probability that <1 % of the plants were infested. The duration of the inspection increased with lot size, but the probability that the infestation level was below 1 % of the plants was lower for small than for large lots. Moreover, large international differences in inspection intensity and the probability that the inspections could detect a level of infestation below 1 % were found: the probability was consistently above 0.95 in one country, while the average probability was below 0.6 in the other countries. We suggest that the EU Member States adopt common maximum acceptable infestation levels and harmonized, statistics-based sampling protocols for plants for planting.

Citrus bark cracking viroid added on EPPO Alert List

Citrus bark cracking viroid added on EPPO Alert List | Pest risk analysis | Scoop.it
an unknown and severe disease was observed in 2007 in hop gardens in Slovenia. The disease spread extremely rapidly and caused severe stunting and death of affected plants. Screening studies on all known pathogens of hop, revealed the presence of Hop stunt viroid (Pospiviroidae, HSVd - hop stunt disease). However, the new disease observed in Slovenia presented some unusual characteristics for HSVd, such as shorter incubation period, higher aggressiveness, and unreliabily of RT-PCR detection (limited to hop cone tissues). Further analysis of symptomatic plants using next generation sequencing (NGS) analysis revealed the presence of Citrus bark cracking viroid (Pospiviroidae, CBCVd). Until this finding, CBCVd had been described only as a minor pathogen of citrus plants. Research studies confirmed that CBCVd was the causal agent of this new viroid disease of hop, which was called ‘severe hop stunt disease’. Hop is a new and highly susceptible host for CBCVd. Because CBCVd on hop is causing a new and emerging disease in the EPPO region, the NPPO of Slovenia suggested its addition to the EPPO Alert List.

Dutch Quickscan on Pectobacterium carotovorum subsp. brasiliense | Pest risk analysis | Scoop.it

Pectobacterium carotovorum subsp. brasiliense (Pcb) is a newly described species for the Netherlands although it may already have been present for many years before it was actually identified. Pcb has been reported from many different parts in the world. The pathogen causes stem rotting of potato plants, soft rotting of potato tubers and blackleg. In the Netherlands, several other bacterial (sub)species are known to be present which cause similar symptoms on potato, e.g. Pectobacterium atrosepticum, Pectobacterium carotovorum subsp. carotovorum (Pcc) and Dickeya sp. The (sub)species in the potato soft rot/blackleg complex may differ in ecological properties and the relative impact of each of the species may depend on environmental conditions. Currently, the additional impact of Pcb for potato production in the Netherlands is unknown.

EFSA Statement on the assessment of the risk of biological control agents of weeds

EFSA Statement on the assessment of the risk of biological control agents of weeds | Pest risk analysis | Scoop.it

Classical biological control has been successfully used in various continents to manage many invasive alien plants originating from Europe, but this approach is still not widely adopted in Europe, despite its advantages (sustainable, effective, efficacious, good safety record) compared to chemical and manual control of weeds. Following the publication in April 2015 of the EFSA PLH Scientific Opinion on the risk posed to plant health in the EU by the intentional release of the bud-galling wasp Trichilogaster acaciaelongifoliae for the control of the invasive alien plant Acacia longifolia, the EFSA PLH Panel is publishing this statement on the procedure to follow should similar requests be made in future. Ideally what is required for an EFSA Opinion on a risk assessment of a BCA release is: (i) host specificity tests of a plant list agreed in advance by an appropriate body; (ii) a risk assessment for plant health produced using a standardized template for the whole of the EU or at the least for an appropriate bio-climatic area within the EU; and (iii) consideration of benefits. This process could be facilitated by an expert working group that would be available to advise the applicant at regular intervals. The role of EFSA is best suited to providing a peer review of a weed BCA risk assessment for the EU considering that peer review of applications prepared by researchers specialized in a particular BCA is the procedure adopted for BCA risk assessment in the countries that have much experience with using exotic BCAs of weeds. 

Muriel Suffert's insight:

It is concluded that "Following the appropriate International Standard for Phytosanitary Measures (ISPM) 3 and the EPPO Standard PM 6/1 will help the releasing authority manage the process. Post-release, as per EPPO PM 6/2, all appropriate safety procedures should be put in place."

Grapevine red blotch-associated virus (GRBaV) added to the EPPO Alert list

Grapevine red blotch-associated virus (GRBaV) added to the EPPO Alert list | Pest risk analysis | Scoop.it

 Grapevine red blotch-associated virus (GRBaV) is a newly identified virus of grapevine (Vitis vinifera) and a putative member of a new genus (which remains to be characterized) within the family Geminiviridae. This virus is associated with red blotch disease that was first reported in California in 2008, and then found in the major grape-growing areas in North America. As GRBaV causes an emerging disease which affects the profitability of vineyards by substantially reducing fruit quality and ripening, the EPPO Panel on Phytosanitary Measures suggested its addition to the EPPO.

 

At present, the presence of GRBaV has been confirmed only in North America. However, in a study conducted in the National Clonal Germplasm Repository (NCGR) in California, grapevine accessions originating from countries outside North America (including European countries) tested positive for the virus. It cannot be concluded from these results that the virus occurs in those countries, but it seems wise that grapevine-growing countries verify the presence or absence of GRBaV in their crops, and eventually include this new virus in certification schemes to prevent its spread.

Dutch Quick scan on Chloridae subflexa (Lepidoptera: Noctuidae)

One living larva of Chloridae subflexa (Lepidoptera: Noctuidae) was intercepted on fruits of Physalis ixocarpa imported from Mexico. Fruits of Physalis spp. are non-regulated products in the EU (i.e. no requirement for a phytosanitary certificate and import inspection) and infested consignments may enter unnoticed. The organism has been reported to feed primarily on Physalis spp. and rarely on other Solanaceae. It can cause damage to fruits of Physalis spp. but no data were found on commercial production of Physalis fruit in the EU. The fruit on which the larva was found was intended for consumption and, therefore, the probability of introduction with import of fruit is considered low. The overall risk (probability x impact) is assessed ‘low’.

Inventory and review of quantitative models for spread of plant pests for use in pest risk assessment for the EU territory | Pest risk analysis | Scoop.it

This report considers the prospects for increasing the use of quantitative models for plant pest spread and dispersal in EFSA Plant Health risk assessments. The agreed major aims were to provide an overview of current modelling approaches and their strengths and weaknesses for risk assessment, and to develop and test a system for risk assessors to select appropriate models for application.

The review located 468 models for plant pest spread and dispersal and these were entered into a searchable and secure Electronic Model Inventory database. We developed a Decision Support Scheme (DSS) to guide model selection.
