enzymatic comparison and mortality of beauveria bassiana against cabbage caterpillar pieris brassicae linn.	beauveria bassiana, an entomopathogenic fungus, is the alternative biocontrol agent exploited against major economic crop pests. pieris brassicae l. is an emerging pest of the brassicaceae family. therefore, in the present study, fungal isolates of beauveria bassiana, viz. mtcc 2028, mtcc 4495, mtcc 6291, and nbaii-11, were evaluated for their virulence against third instar larvae of p. brassicae. among all these fungal isolates, maximum mortality (86.66%) was recorded in b. bassiana mtcc 4495 a ...	2017	28262388
two eisosome proteins play opposite roles in autophagic control and sustain cell integrity, function and pathogenicity in beauveria bassiana.	pil1a and pil1b are two core eisosome proteins that are homologous to yeast pil1/lsp1 or filamentous fungal pil1a/pil1b but have been unexplored in entomopathogenic fungi. here we examined subcellular localization and functions of pil1a and pil1b in beauveria bassiana, a fungal insect pathogen. either localization or co-localization experiments of the two proteins demonstrated that pil1a and pil1b were simultaneously localized at the periphery of hyphal cells for formation of stable, punctuate s ...	2017	28276124
microbial pest control agents: are they a specific and safe tool for insect pest management?	microorganisms (viruses, bacteria and fungi) or their bioactive agents can be used as active substances and therefore are referred as microbial pest control agents (mpca). they are used as alternative strategies to chemical insecticides to counteract the development of resistances and to reduce adverse effects on both environment and human health. these natural entomopathogenic agents, which have specific modes of action, are generally considered safer as compared to conventional chemical insect ...	2017	28292241
global insight into lysine acetylation events and their links to biological aspects in beauveria bassiana, a fungal insect pathogen.	lysine acetylation (kac) events in filamentous fungi are poorly explored. here we show a lysine acetylome generated by lc-ms/ms analysis of immunoaffinity-based kac peptides from normal hyphal cells of beauveria bassiana, a fungal entomopathogen. the acetylome comprised 283 kac proteins and 464 kac sites. these proteins were enriched to eight molecular functions, 20 cellular components, 27 biological processes, 20 kegg pathways and 12 subcellular localizations. all kac sites were characterized a ...	2017	28295016
passive vectoring of entomopathogenic fungus beauveria bassiana among the wax moth galleria mellonella larvae by the ectoparasitoid habrobracon hebetor females.	females of the ectoparasitoid habrobracon hebetor attack and envenomate numerous host individuals during oviposition. the vectoring of the entomopathogenic fungus beauveria bassiana during the adhesion stage by ectoparasitoid females among the wax moth larvae galleria mellonella was explored under laboratory conditions. vectoring occurred both from infected parasitoids to wax moth larvae and from infected to healthy wax moth larvae by parasitoids. the efficacy of vectoring in both cases was dose ...	2017	28296161
susceptibility of insecticide resistant bed bugs (cimex lectularius) to infection by fungal biopesticide.	bed bugs are a public health concern, and their incidence is increasing worldwide. bed bug infestations are notoriously difficult to eradicate, further exacerbated by widespread resistance to pyrethroid and neonicotinoid insecticides. this study evaluated the efficacy of the newly developed fungal biopesticide, aprehend™, containing beauveria bassiana, against insecticide-resistant bed bugs.	2017	28321982
endophytic fungi alter sucking bug responses to cotton reproductive structures.	all plants including cotton host a wide range of microorganisms as endophytes. there is a growing appreciation of the prevalence, ecological significance and management potential of facultative fungal endophytes in protecting plants from pests, pathogens and environmental stressors. hemipteran sucking bugs have emerged as major pests across the us cotton belt, reducing yields directly by feeding on developing reproductive structures and indirectly by vectoring plant pathogens. we used no-choice ...	2017	28328087
lethal and sublethal effects of some chemical and biological insecticides on tuta absoluta (lepidoptera: gelechiidae) eggs and neonates.	tuta absoluta (meyrick) is one of the serious pests of tomatoes. this study was conducted to evaluate the effects of some chemical and biological insecticides on t. absoluta . the insecticides tested were diazinon, dichlorvos, chlorantraniliprole, deltamethrin, acetamiprid, imidacloprid, spinosad, abamectin, indoxacarb, bacillus thuringiensis berliner, beauveria bassiana (balsamo) vuillemin, and metarhizium anisopliae (metschnikoff) sorokin. sublethal effects for the most effective insecticides ...	2017	28334249
effects of sub-culturing on genetic and physiological parameters in different beauveria bassiana isolates.	beauveria bassiana is a fungus which is widely used as a biological insecticide to control a number of economically important insect pests. knowledge of the genetic diversity of the isolates, understanding the underlying nature of these evolutionary phenomena and finding appropriate and simple screening tools play an important role in developing effective biocontrol agents. here, we monitored changes of electrophoretic karyotype of small molecules of extrachromosomal dnas, presumably mitochondri ...	2017	28342852
highly potent host external immunity acts as a strong selective force enhancing rapid parasite virulence evolution.	virulence is often under selection during host-parasite coevolution. in order to increase fitness, parasites are predicted to circumvent and overcome host immunity. a particular challenge for pathogens are external immune systems, chemical defence systems comprised of potent antimicrobial compounds released by prospective hosts into the environment. we carried out an evolution experiment, allowing for coevolution to occur, with the entomopathogenic fungus, beauveria bassiana, and the red flour b ...	2017	28345225
transcriptomic analysis of two beauveria bassiana strains grown on cuticle extracts of the silkworm uncovers their different metabolic response at early infection stage.	beauveria bassiana is an important entomopathogenic fungus which not only widely distributes in the environment but also shows phenotypic diversity. however, the mechanism of pathogenic differences among natural b. bassiana strains has not been revealed at transcriptome-wide level. in the present study, in order to explore the mechanism, two b. bassiana strains with different pathogenicity were isolated from silkworms (bombyx mori l.) and selected to analyze the gene expression of early stage by ...	2017	28359865
crispr/cas9-mediated efficient genome editing via blastospore-based transformation in entomopathogenic fungus beauveria bassiana.	beauveria bassiana is an environmentally friendly alternative to chemical insecticides against various agricultural insect pests and vectors of human diseases. however, its application has been limited due to slow kill and sensitivity to abiotic stresses. understanding of the molecular pathogenesis and physiological characteristics would facilitate improvement of the fungal performance. loss-of-function mutagenesis is the most powerful tool to characterize gene functions, but it is hampered by t ...	2017	28368054
upregulation of a trypsin-like serine protease gene in antheraea pernyi (lepidoptera: saturniidae) strains exposed to different pathogens.	antheraea pernyi guérin-méneville is used for silk production and as a food resource. its infection by exogenous pathogens, including microsporidia, fungi, bacteria, and virus, can lead to silkworm diseases, causing major economic losses. a trypsin-like serine protease gene (tls) was found in a. pernyi transcriptome data resulting from two different infection experiments. the cdna sequence of aptls was 1,020 bp in length and contained an open reading frame of 774 bp encoding a 257-amino acid pro ...	2017	28369437
