    Importation of Fresh Beans (Phaseolus vulgaris L.), Shelled or in Pods, from Jordan into the Continental United States A Qualitative, Pathway-Initiated Risk Assessment February 14, 2011 Version 2 Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Pest Risk Assessment for Beans from Jordan Executive Summary In this risk assessment we examined the risks associated with the importation of fresh beans (Phaseolus vulgaris L.), in pods (French, green, snap, and string beans) or shelled, from the Kingdom of Jordan into the continental United States. We developed a list of pests associated with beans (in any country) that occur in Jordan on any host based on scientific literature, previous commodity risk assessments, records of intercepted pests at ports-of-entry, and information from experts on bean production. This is a qualitative risk assessment, as we express estimates of risk in descriptive terms (High, Medium, and Low) rather than numerically in probabilities or frequencies. We identified seven quarantine pests likely to follow the pathway of introduction. We estimated Consequences of Introduction by assessing five elements that reflect the biology and ecology of the pests: climate-host interaction, host range, dispersal potential, economic impact, and environmental impact. We estimated Likelihood of Introduction values by considering both the quantity of the commodity imported annually and the potential for pest introduction and establishment. We summed the Consequences of Introduction and Likelihood of Introduction values to estimate overall Pest Risk Potentials, which describe risk in the absence of mitigation.

Host-specific mortality from natural enemies is one of the most widely tested hypotheses in community ecology to explain the high biodiversity of forests. The effects of fungal pathogens on seedling survival are usually discussed under the framework of the Janzen-Connell (JC) hypothesis, which posits that seedlings are more likely to survive when dispersed far from the parent tree or at low densities due to pressure from host-specific pathogens (Janzen 1970, Connell 1971).

The selected genera of plants were Acacia, Albizia, Bauhinia, Berberis, Caesalpinia, Cassia, Cornus, Hamamelis, Jasminus, Ligustrum, Lonicera, Nerium, and Robinia. A total of 120 fungal genera have been found in plant tissues originating from several countries. Bauhinia and Cornus showed the highest diversity of endophytes, whereas Hamamelis, Jasminus, Lonicera, and Robinia exhibited the lowest. The most frequently detected fungi were Aspergillus, Colletotrichum, Fusarium, Penicillium, Phyllosticta, and Alternaria. Plants and plant products represent an inoculum source of several mutualistic or pathogenic fungi, including quarantine pathogens.

Mycosphere 10(1), 798–1079, Doi 10.5943/mycosphere/10/1/19 Abstract Endophytic fungi are symptomless internal inhabits of plant tissues. They are implicated in the production of antibiotic and other compounds of therapeutic importance. Ecologically they provide several benefits to plants, including protection from plant pathogens. There have been numerous studies on the biodiversity and ecology of endophytic fungi. Some taxa dominate and occur frequently when compared to others due to adaptations or capabilities to produce different primary and secondary metabolites. It is therefore of interest to examine different fungal species and major taxonomic groups to which these fungi belong for bioactive compound production. In the present paper a list of endophytes based on the available literature is reported. More than 800 genera have been reported worldwide. Dominant genera are Alternaria, Aspergillus, Colletotrichum, Fusarium, Penicillium, and Phoma. Most endophyte studies have been on angiosperms followed by gymnosperms. Among the different substrates, leaf endophytes have been studied and analyzed in more detail when compared to other parts. Most investigations are from Asian countries such as China, India, European countries such as Germany, Spain and the UK in addition to major contributions from Brazil and the USA.

Because this commodity has not been imported from Colombia before, the United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS) conducted a pathway-initiated risk assessment to determine the risks associated with importing these ‘Hass’ avocados. We developed a list of pests known to occur in Colombia and associated with avocado based on the scientific literature, port-of-entry pest interception data, and information provided by the Colombian Ministry for Agriculture and Rural Development, and the Colombian Agricultural Institute (ICA). Commercial ‘Hass’ avocado is a conditional non-host for the fruit flies, Anastrepha fraterculus, A. striata, and Ceratitis spp. Thus, we did not list these organisms in the assessment. We determined that three quarantine arthropod pests were likely to follow the pathway, and qualitatively analyzed them to determine the unmitigated risk posed to the United States. Pest Taxonomy Pest Risk Potential Heilipus lauri Boheman Coleoptera: Curculionidae High Heilipus trifasciatus (Fabricius) Coleoptera: Curculionidae High Stenoma catenifer Walsingham Lepidoptera: Elaschistidae High All pests were rated High and for pests with High pest risk potential, mitigations beyond port-of- entry inspection are recommended.

Carlucci1, M.L. Raimondo1, J. Santos2, A.J.L. Phillips2 Key words Abstract Plectosphaerella cucumerina, most frequently encountered in its Plectosporium state, is well known as a pathogen of several plant species causing fruit, root and collar rot, and collapse. It is considered to pose a D1/D2 serious threat to melon (Cucumis melo) production in Italy. In the present study, an intensive sampling of diseased ITS cucurbits as well as tomato and bell pepper was done and the fungal pathogens present on them were isolated. LSU Phylogenetic relationships of the isolates were determined through a study of ribosomal RNA gene sequences phylogeny (ITS cluster and D1/D2 domain of the 28S rRNA gene). Combining morphological, culture and molecular data, six Plectosporium species were distinguished. One of these (Pa. cucumerina) is already known. Four new species are described as rDNA Plectosphaerella citrullae, Pa. pauciseptata, Pa. plurivora and Pa. ramiseptata. Acremonium cucurbitacearum is systematics shown to be a synonym of Nodulisporium melonis and is transferred to Plectosphaerella as Plectosphaerella melonis taxonomy comb. nov.

In addition, C. gloeosporioides and C. boninense were isolated from plants in the Anthracnose Agavaceae. All species of Colletotrichum described on Agavaceae were evaluated based on Molecular phylogeny type specimens. A key to the five species of Colletotrichum on Agavaceae is included.

    The Colletotrichum Gigasporum Species Complex

    Persoonia 33, 2014: 83–97 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE http://dx.doi.org/10.3767/003158514X684447 The Colletotrichum gigasporum species complex F. Liu1,2, L. Cai1, P.W. Crous2,3,4, U. Damm3,5 Key words Abstract In a preliminary analysis, 21 Colletotrichum strains with large conidia preserved in the CBS culture col- lection clustered with a recently described species, C. gigasporum, forming a clade distinct from other currently Ascomycota known Colletotrichum species complexes. Multi-locus phylogenetic analyses (ITS, ACT, TUB2, CHS-1, GAPDH) morphology as well as each of the single-locus analyses resolved seven distinct species, one of them being C. gigasporum. phylogeny Colletotrichum gigasporum and its close allies thus constitute a previously unknown species complex with shared systematics morphological features. Five of the seven species accepted in the C. gigasporum species complex are described here as novel species, namely C. arxii, C. magnisporum, C. pseudomajus, C. radicis and C. vietnamense. A spe- cies represented by a single sterile strain, namely CBS 159.50, was not described as novel species, and is treated as Colletotrichum sp. CBS 159.50. Furthermore, C. thailandicum is reduced to synonymy with C. gigasporum. Article info Received: 11 February 2014; Accepted: 6 March 2014; Published: 29 August 2014. INTRODUCTION The objectives of this study are to clarify the genetic and taxo- nomic relationships of Colletotrichum strains from various hosts Colletotrichum gigasporum was originally reported from healthy and geographic areas thought to be closely related to C. giga- leaves of Centella asiatica in Madagascar and Stylosanthes sporum, and to describe the new species from this complex.
