TL;DR: Current information on development, use and future directions of insect-specific viruses, bacteria, fungi and nematodes as components of integrated pest management strategies for control of arthropod pests of crops, forests, urban habitats, and insects of medical and veterinary importance is presented.

TL;DR: It is concluded that one of the remaining challenges is to use new "omics" technologies to understand how this diverse array of factors is integrated and controlled during infection.

TL;DR: Mortality outbreaks affecting C. gigas have increased in terms of intensity and geographic distribution, and epidemiologic surveys have lead to the incrimination of pathogens, specifically OsHV-1 and bacteria of the Vibrio genus, in particular VIBrio aestuarianus.

TL;DR: An updated overview of main diseases and implicated bacterial species affecting bivalves, their diversity and virulence factors, the diagnostic methods available as well as information on the dynamics of the host-parasite relationship are provided.

TL;DR: A PCR assay from this 18S rRNA gene region is shown to be specific to EHP, did not react to 2 other parasitic pathogens, an amoeba and the cotton shrimp disease microsporidium, nor to genomic DNA of various crustaceans including polychaetes, squids, crabs and krill.

TL;DR: This work reviews the literature on selective breeding programs for disease resistance in oyster species, and the impact of triploidy on such resistance, and it seems breeding for higher resistance to one disease does not confer higher resistance or susceptibility to another disease.

TL;DR: Resistance to Cry1Ac and the observed cross-resistance to other Bt toxins could accelerate evolution of H. zea resistance to currently registered Bt sprays and pyramided Bt crops.

TL;DR: Honey bees (Apis mellifera) are infected by two species of microsporidia: Nosema apis and Nosemaceranae, and it is demonstrated that mixed Nosema species infections negatively affected honey bee survival more than single species infections.

TL;DR: It was demonstrated for the first time the pathogenic activity of V. splendidus strains on reared-larvae of scallop A. purpuratus and prompt the necessity to maintain this species at concentrations lower than 10(4) CFU mL(-1) to avoid episodes of mass mortalities in scallops hatcheries.

TL;DR: This is the first study to characterize how the diversity of bee preferred resinous plants in the US may affect bee health, and could guide future studies on the therapeutic potential of propolis for bees.

TL;DR: The aim of this paper is to provide an overview of the pathological basis of bivalve disease (defensive, regressive and progressive phenomena) and contribute to the standardised terminology for bivalves molluscan disease in the context of comparative pathology.

TL;DR: Several studies reported many genes and pathways critically involved in neoplastic transformation in Mya arenaria, Mytilus spp.

TL;DR: A synthesis of the understanding of the life cycles and environmental influences on haplosporidians, with particular emphasis on the important pathogens Haplosporidium nelsoni and Bonamia ostreae is provided.

TL;DR: The findings support the use of liquid culture fermentation as a cost-effective process to rapidly produce high yields of stable and infective blastospores of either B. bassiana or I. fumosorosea and support further evaluation of blastospore sprayable formulations for the control of soft-bodied insects.

TL;DR: This research resulted in the identification of fragment length polymorphisms in ITS1 and ITS1-2 markers, which enabled a diagnostic method to differentiate both honey bee trypanosomatid species without the need for sequencing.

TL;DR: It is shown that a heterologous expressed peptide corresponding to cadherin repeat 7 to the membrane proximal extracellular domain (CR7-MPED) in the S. exigua Cadherin 1b (SeCad1b) binds Cry1Ac and Cry2Aa, having major implications for resistance management for S.Exigua in Bt crops.

TL;DR: Bombus atratus bumblebees from Colombia that were caught in the wild and from breeding programs were screened for a broad set of bee pathogens and Lake Sinai Virus was discovered for the first time and infection by other common viruses was confirmed.

TL;DR: Findings indicated that cultivated bivalves may face potential threats from OsHV-1 types found in this study, which demonstrated that two clades were associated with abnormal mortalities of the scallop, Chlamys farrier and the calm, Scapharca broughtonii in China.

TL;DR: It is suggested that plants either recruit fungal associates from the surrounding soil environment or even govern the composition of Metarhizium populations found in the rhizosphere of different crops within a single agroecosystem.

TL;DR: Comparisons among studies suggest that the mixed lineages of US honey bees may be less susceptible to N. ceranae infections than are European bees or that the US isolates of the pathogen are less infective and less virulent than European isolates.

TL;DR: This is the first report of the control of shrimp pathogen V. cholerae with Bdellovibrio bacteriovorus, which exhibited significant bacteriolytic effects on the V.Cholerae pathogen and displayed a positive protective efficacy against experimental V. Cholerae infection in P. vannamei.

TL;DR: The developed molecular tools can be used to elucidate the extent to which the competitive interactions affect EPN populations and help to develop strategies to achieve good persistence and natural EPN recycling, in particular in systems where native EPN levels are low, such as annual crops.

TL;DR: Prior establishment in the host ventriculus by N. ceranae inhibited DWV while prior infection by DWV did not impact N. Ceranae, highlighting an asymmetry in the competitive interaction between these emerging pathogens.

TL;DR: The results indicate that a diversified genetic basis may exist for the Cry1F resistance in S. frugiperda and that the fitness costs of RR-PR and RR-FL appeared to be non-recessive.

TL;DR: Pot experiment suggested that soil drenching with spore-crystal mixture of Cry6Aa2 can clearly lighten the disease of root-knot nematode, including reduction of galling index and egg masses on host plant root, decreasing final population of nematodes in soil.

TL;DR: The results suggest that the entomopathogenic Hypocreales in the phylloplane could result from the dispersal of fungal propagules from the soil, which might be their habitat of origin; a few isolates, including EABb 09/28-Fil of Beauveria bassiana, inhabit only the phytoplane.

TL;DR: A catalogue of the genetic and -omic tools available for bivalve species and examples of how -omics has contributed to the advancement of marine bivalves disease research are provided, with a special focus in the areas of immunity, bivalce-pathogen interactions, mechanisms of disease resistance and pathogen virulence, and disease diagnosis.

TL;DR: The population of E. cloacae in the gut of infected larvae exceeded over the other two microbes and resulted in pathogenicity and death of S. litura larvae, indicating that E. Cloacae can have the potential to be used as a promising biological control agent.

TL;DR: It is proposed that T. rapae can perceive and react towards IGP risk posed by M. brunneum and has the potential to be used for biological control against D. radicum and T. Rapae populations.

TL;DR: In this first de novo transcriptome of an entomophthoralean fungus, expression of many pathogenicity-related genes, including secreted hydrolytic enzymes and genes related to morphological reorganization and nutrition uptake are detected.
