sp. nov. (Hypocreales: Hypocreaceae) on sp. from Yunnan, PR China.

Background: is a large genus of fungicolous fungi, parasitising the fruiting bodies of Agaricales, Boletales, Helotiales, Pezizales and Polyporales. currently comprises of 147 species widely distributed in Australia, China, France, Germany, Italy, Japan, North America, Sri Lanka, Thailand and UK. Amongst them, 28 species have been recorded in China.

Molecular Phylogeny and Morphology of (= ) (Amphisphaeriaceae).

Amphisphaeriaceous taxa (fungi) are saprobes on decaying wood in terrestrial, mangrove, and freshwater habitats. The generic boundaries of the family have traditionally been based on morphology, and the delimitation of genera has always been challenging. species have clypeate ascomata and 1-septate ascospores and a coelomycetous asexual morph.

A new genus of Bambusicolaceae (Pleosporales) on (Fagales) from Italy.

Background: In this study, we introduce gen. nov. in the family of Bambusicolaceae (Pleosporales), to accommodate sp.

Additions to Phaeosphaeriaceae (Pleosporales): gen. nov., sp. nov., sp. nov. and a new host record of from Musaceae.

A novel ascomycetous genus, , occurring on leaf litter of (Zingiberaceae) in Taiwan, is described and illustrated. is characterized by dark brown to black, superficial, obpyriform, pycnidial conidiomata with a distinct elongate neck, and oval to oblong, hyaline, aseptate conidia. Phylogenetic analyses (maximum likelihood, maximum parsimony and Bayesian) of combined ITS, LSU, SSU and -α sequence data revealed as a distinct genus within the family Phaeosphaeriaceae with high statistical support.

(Acrogenosporaceae, Minutisphaerales) Appears to Be a Very Diverse Genus.

During a study of diversity and taxonomy of lignicolous freshwater fungi in China, nine species of were collected. Seven of these were new species and they are described and illustrated. With morphology, additional evidence to support establishment of new species is provided by phylogeny derived from DNA sequence analyses of a combined LSU, SSU, TEF1α, and RPB2 sequence dataset.

Taxonomy and phylogenetic appraisal of sp. nov. and (Didymosphaeriaceae, Pleosporales) on Musaceae from Thailand.

Tropical plants host a range of fungal niches including endophytes, pathogens, epiphytes and saprobes. A study undertaken to discover the saprobic fungal species associated with sp. (banana) from northern Thailand found two hyphomycetous taxa of (Didymosphaeriaceae, Pleosporales).

sp. nov. (Distoseptisporaceae) on bamboo from China and Thailand.

Background: Bamboo is a widespread plant with medicinal value. During our taxonomic study on medicinal plants, three collections of were made from China and Thailand. Phylogenetic analyses of combined LSU, ITS and sequence data showed that two collections represented a new species, phylogenetically distinct from other described species in .

Identifying obstacles and ranking common biological control research priorities for Europe to manage most economically important pests in arable, vegetable and perennial crops.

EU agriculture is currently in transition from conventional crop protection to integrated pest management (IPM). Because biocontrol is a key component of IPM, many European countries recently have intensified their national efforts on biocontrol research and innovation (R&I), although such initiatives are often fragmented. The operational outputs of national efforts would benefit from closer collaboration among stakeholders via transnationally coordinated approaches, as most economically important pests are similar across Europe.

S argassum muticum-synthesized silver nanoparticles: an effective control tool against mosquito vectors and bacterial pathogens.

Mosquito-borne diseases represent a deadly threat for millions of people worldwide. Furthermore, pathogens and parasites polluting water also constitute a severe plague for populations of developing countries. In this research, silver nanoparticles (AgNP) were synthesized using the aqueous extract of the seaweed Sargassum muticum.

Chemical control of the Asian citrus psyllid and of huanglongbing disease in citrus.

By 2014, huanglongbing (HLB), the most destructive disease of citrus, and its insect vector, the Asian citrus psyllid (ACP), Diaphorina citri (Kuwayama), became established in all major citrus-growing regions of the world, including the United States, with the exception of California. At present, application of insecticides is the most widely followed option for reducing ACP populations, while application of antibiotics for suppressing HLB disease/symptoms is being practiced in some citrus-growing regions. Application of insecticides during the dormant winter season, along with cultivation of HLB-free seedlings and early detection and removal of symptomatic and asymptomatic trees, has been very effective in managing ACP.

Alternative splicing and highly variable cadherin transcripts associated with field-evolved resistance of pink bollworm to bt cotton in India.

Evolution of resistance by insect pests can reduce the benefits of insecticidal proteins from Bacillus thuringiensis (Bt) that are used extensively in sprays and transgenic crops. Despite considerable knowledge of the genes conferring insect resistance to Bt toxins in laboratory-selected strains and in field populations exposed to Bt sprays, understanding of the genetic basis of field-evolved resistance to Bt crops remains limited. In particular, previous work has not identified the genes conferring resistance in any cases where field-evolved resistance has reduced the efficacy of a Bt crop.

Host tracking or cryptic adaptation? Phylogeography of Pediobius saulius (Hymenoptera, Eulophidae), a parasitoid of the highly invasive horse-chestnut leafminer.

Classical biological control is often advocated as a tool for managing invasive species. However, accurate evaluations of parasitoid species complexes and assessment of host specificity are impeded by the lack of morphological variation. Here, we study the possibility of host races/species within the eulophid wasp Pediobius saulius, a pupal generalist parasitoid that parasitize the highly invasive horse-chestnut leaf-mining moth Cameraria ohridella.

Erwinia amylovora expresses fast and simultaneously hrp/dsp virulence genes during flower infection on apple trees.

Background: Pathogen entry through host blossoms is the predominant infection pathway of the gram-negative bacterium Erwinia amylovora leading to manifestation of the disease fire blight. Like in other economically important plant pathogens, E. amylovora pathogenicity depends on a type III secretion system encoded by hrp genes.

Development and evaluation of a real-time PCR assay targeting chromosomal DNA of Erwinia amylovora.

Aims: To develop and evaluate a new and reliable real-time PCR detection protocol on chromosomal DNA of the contagious plant pathogenic bacterium Erwinia amylovora, the causal agent of fire blight.

Methods And Results: A Taqman minor-groove-binder real-time PCR assay targeting a hypothetical protein coding gene of Erw. amylovora has been developed.
