Plants generate energy flows through natural food webs, driven by competition for resources among organisms, which are part of a complex network multitrophic interactions. Here, we demonstrate that the interaction between tomato plants and phytophagous insect is hidden interplay their respective microbiotas. Tomato colonized soil fungus Trichoderma afroharzianum , beneficial microorganism widely used in agriculture as biocontrol agent, negatively affects development survival lepidopteran...
Abstract The neonicotinoid Clothianidin has a negative impact on NF-κB signaling and immune responses controlled by this transcription factor, which can boost the proliferation of honey bee parasites pathogens. This effect been well documented for replication deformed wing virus (DWV) induced in bees bearing an asymptomatic infection. Here, we conduct infestation experiments treated to show that immune-suppression exerted is associated with enhanced fertility parasitic mite Varroa destructor...
Endophytic fungi (EF) can enhance both plant growth and defense barriers against pests pathogens, contributing to the reduction of chemical pesticides fertilizers use in agriculture. Beauveria bassiana is an entomopathogenic fungus showing endophytism several crops, often associated with a good capacity limit development disease agents. However, diversity protective efficacy response different strains be remarkable needs carefully assessed for successful predictable these beneficial...
The rise of the holobiont concept confers a prominent importance to endophytic associates plants, particularly species known be able exert mutualistic role as defensive or growth-promoting agents. finding that many entomopathogenic fungi are harbored within plant tissues and possess bioactive properties going beyond merely anti-insectan effect has recently prompted widespread investigational activity concerning their occurrence functions in crops, aim an applicative exploitation conforming...
Despite its ecological and economic importance, many aspects of Varroa destructor’s biology remain poorly understood, particularly defense mechanisms against pathogens. The limited knowledge Varroa’s immunity has hindered the development RNA interference (RNAi)-based strategies targeting immune-related genes. In this study, we investigated immune gene repertoire V. destructor by querying NCBI nr protein database comparing it to model species ticks (Ixodes scapularis) mites (Galendromus...
Although agricultural activities can strongly affect soil biodiversity and health, with consequences on the provisioning of biota-mediated functions, their specific impact invertebrate communities is far from being fully elucidated. In this study, associated soils six habitat types, including both semi-natural cropping systems, one most intensively farmed areas in Europe, Po Valley (North Italy), were characterized using eDNA metabarcoding approach. The aims to examine variation taxonomic...
Deformed wing virus (DWV) is a major honey bee pathogen that actively transmitted by the parasitic mite Varroa destructor and plays primary role in Apis mellifera winter colony losses. Despite intense investigation on this pollinator, which has unique environmental economic importance, mechanisms underlying molecular interactions between DWV bees are still poorly understood. Here, we report group of proteins, identified mass spectrometry, specifically co-immunoprecipitate with particles....
Abstract Background Venom is one of the most important sources regulation factors used by parasitic Hymenoptera to redirect host physiology in favour developing offspring. This has stimulated a number studies, both at functional and “omics” level, which, however, are still quite limited for ectophagous parasitoids that permanently paralyze suppress their victims (i.e., idiobiont parasitoids). Results Here we present combined transcriptomic proteomic study venom generalist wasp Bracon...
Insects and fungi represent two of the most widespread groupings organisms in nature, occurring every kind ecological context impacting agriculture other human activities various ways. Moreover, they can be observed to reciprocally interact, establishing a wide range symbiotic relationships, from mutualism antagonism. The outcome these relationships turn affect extent at which species both exert their noxious effects, as well management practices are adopted counter them. In conjunction with...
Acetylcholine (ACh) is one the major neurotransmitters in insects, whose role mediating synaptic interactions between neurons central nervous system well characterized. It also plays largely unexplored regulatory functions non-neuronal tissues. Here we demonstrate that ACh signaling involved modulation of innate immune response Drosophila melanogaster. Knockdown synthesis or vesicular transport reduced activation drosomycin (drs), a gene encoding an antimicrobial peptide, adult flies...
Beauveria bassiana (Bb) is a widespread entomopathogenic fungus widely used in agriculture for crop protection. Other than pest control, fungi belonging to the B. complex represent an important microbial resource agroecosystems, considering their multiple interactions with other microorganisms as antagonists of phytopathogens, or plants endophytic colonizers and growth promoters. Here, we characterised field collected commercial isolates relative environmental factors that affect growth. We...
The association between the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Aphididae), and endophagous parasitoid wasp Aphidius ervi Haliday (Hymenoptera: Braconidae) offers a unique model system for studying molecular mechanisms underlying complex interactions parasitoid, its host associated primary symbiont. Here, we investigate in vivo functional role of most abundant component A. venom, Ae-γ-glutamyl transpeptidase (Ae-γ-GT), which is known to induce castration. Microinjections...
Abstract The host immunosuppression by parasitic wasps is an important component of the regulation strategy. venom injected at oviposition one key‐factors involved in this alteration and, some parasitoids, its immunosuppressive role complemented wasp's symbionts. Most studies research area are related to hosts belonging Lepidoptera and Diptera, for which a strong immune response observed, whereas little known hemimetabolous species, characterized apparently much weaker defense barriers. To...
Insects possess an effective immune system, which has been extensively characterized in several model species, revealing a plethora of conserved genes involved recognition, signaling, and responses to pathogens parasites. However, some taxonomic groups, by peculiar trophic niches, such as plant-sap feeders, are often important pests crops forestry ecosystems, have largely overlooked regarding their gene repertoire. Here we annotated the soft scale insects (Hemiptera: Coccidae) for omics data...
In the last decade, Botryosphaeria dothidea has been steadily reported as an associate of gall midges (Diptera, Cecidomyiidae) in a variety host plants and ecological settings. This cosmopolitan fungus is well-known for its ability to colonize many plant species, both pathogen endophyte. Thus, shift from this general habit lifestyle involving strict symbiotic relationship with insect introduces expectancy possible strain specialization which could reflect separated phylogenetic lineages....
A series of isolates Cladosporium spp. were recovered in the course a cooperative study on galls formed by midges genus Asphondylia (Diptera, Cecidomyidae) several species Lamiaceae. The finding these fungi both normal and galled flowers was taken as an indication that they do not have definite relationship with midges. Moreover, identification based DNA sequencing showed are taxonomically heterogeneous belong to which classified two different complexes. Two new species, polonicum...
In the course of investigations on complex phenomenon bee decline, Aspergillus flavus was isolated from haemocoel worker bees. Observations metabolomic profile this strain showed kojic acid to be dominant product in cultures Czapek-Dox broth. However, an accurate review papers documenting secondary metabolite production A. also that isomer acid, identified as 5-(hydroxymethyl)-furan-3-carboxylic and named flufuran is reported species. The spectroscopic data were almost identical those...
Varroa destructor is an ectoparasite of honey bees and active disease vector, which represents one the most severe threats for beekeeping industry. This parasitic mite feeds on host’s body fluids through a wound in cuticle, allows food uptake by mother its progeny, offering potential route entrance infecting microorganisms. Mite feeding associated with saliva injection, whose role still largely unknown. Here we try to fill this gap identifying putative host regulation factors present V ....
Cladosporium cladosporioides is an extremely widespread fungus involved in associations ranging from mutualistic to pathogenic and the most frequently represented species sequence databases, such as Genbank. The taxonomy of species, currently based on integration molecular data with morphological cultural characters, frequent need revision. Hence, recently developed delimitation methods can be helpful explore cryptic diversity this genus. Considering a previous study that reported several...
