The activation of autophagy has been extensively described as a pro-survival strategy, which helps to keep cells alive following deprivation nutrients/growth factors and other stressful cellular conditions. In addition cytoprotective effects, can accompany cell death. Autophagic vacuoles be observed before or during death, but the role in death process is still controversial. A complex interplay between apoptosis come light, taking into account that numerous genes, such p53 Bcl-2 family...
Lactic acid bacteria (LAB) are an important group of honeybee gut microbiota. These involved in food digestion, stimulate the immune system, and may antagonize undesirable microorganisms gastrointestinal tract.
Lactic acid bacteria could positively affect the health of honey bees, including nutritional supplementation, immune system development and pathogen colonization resistance. Based on these considerations present study evaluated predominant Acid Bacteria (LAB) species from beebread as well social stomach midgut Apis mellifera ligustica bee foragers. In detail, for each compartment, diversity in biotypes was ascertained through multiple culture-dependent approaches, consisting Polymerase Chain...
The balance of the gut microbiome is important for honey bee’s growth and development, immune function defense against pathogens. use a beneficial bacteria-based strategy prevention biocontrol American foulbrood (AFB) European (EFB) diseases in bees offers interesting prospects. Lactic acid bacteria (LAB) are common inhabitants gastrointestinal tract bee. Among LABs associated with bee microbiota, Lactiplantibacillus plantarum (previously Lactobacillus plantarum) Apilactobacillus kunkeei...
Chalkbrood is the manifestation of fungal disease caused by Ascosphaera apis, which affects brood developing honeybees, particularly in Apis mellifera colonies. Recently, Metschnikowia pulcherrima have been proposed as biocontrol agent winemaking and for management major postharvest soil-borne plant pathogenic fungi. In this study, antagonistic activity three M. strains against fifteen A. apis strains, isolated from contaminated hives mellifera, was evaluated, with a specific focus ona...
Paenibacillus larvae is the causative agent of American foulbrood (AFB), a severe bacterial disease that affects honeybees. The present study evaluated, in vitro, antimicrobial activity sixty-one Lactiplantibacillus plantarum strains, against P. ATCC 9545. Five strains (P8, P25, P86, P95 and P100) showed greatest antagonism 9545were selected for further physiological biochemical characterizations. In particular, hydrophobicity, auto-aggregation, exopolysaccharides production, osmotic...
In this study we report the effects of fungal metabolites isolated from cultures fungus Trichoderma citrinoviride ITEM 4484 on feeding preference aphid Rhopalosiphum padi, a major pest cereal crops. Different phagodeterrent were purified by combination direct and reverse phase column chromatography thin-layer chromatography. Chemical investigations, spectroscopic chemical methods, led to identification different long chain primary alcohols (LCOHs) general formula R-OH, wherein R is long,...
The meadow spittlebug, Philaenus spumarius L. (Hemiptera, Aphrophoridae) is a commonly found vector of Xylella fastidiosa Wells et al. (1987) strain subspecies pauca associated with the "Olive Quick Decline Syndrome" in Italy. To contribute to knowledge adult P. chemoreceptivity, electroantennographic (EAG) responses both sexes 50 volatile organic compounds (VOCs) including aliphatic aldehydes, alcohols, esters, and ketones, terpenoids, aromatics were recorded. Measurable EAG elicited by all...
Two novel metabolites with potential antifeedant activity were isolated from cultures of the fungus Trichoderma citrinoviride strain ITEM 4484 grown in solid-state fermentation on sterile rice kernels. The producing was identified at species level by sequence analysis internal transcribed spacer regions ITS-1 and ITS-2 nuclear rDNA a fragment translation elongation factor gene TEF-1α. Fractionation column chromatography TLC culture organic extract, followed feeding preference tests aphid...
Abstract The meadow spittlebug, Philaenus spumarius , is a highly polyphagous widespread species, playing major role in the transmission of bacterium Xylella fastidiosa subspecies pauca agent “Olive Quick Decline Syndrome”. Essential oils (EOs) are an important source bio-active volatile compounds that could interfere with basic metabolic, biochemical, physiological, and behavioural functions insects. Here, we report electrophysiological responses adult P . towards some EOs related plants....
Ascosphaera apis is an entomopathogenic fungus that affects honeybees. In stressful conditions, this (due not only to its presence, but also the combination of other biotic and abiotic stressors) can cause chalkbrood disease. recent years, there has been increasing attention paid towards use lactic acid bacteria (LAB) in honeybees’ diets improve their health, productivity ability resist infections by pathogenic microorganisms. The screening 22 strains Lactiplantibacillus plantarum, isolated...
Abstract Background The meadow spittlebug Philaenus spumarius L. is the vector for bacterium Xylella fastidiosa subspecies pauca , involved in olive quick decline syndrome (OQDS) Salento (Italy). Control of P. key to limiting transmission and an innovative approach can be based on effective natural compounds biocontrol agents. Entomopathogenic fungi are important source bioactive molecules that play a role relationship between microorganisms insects. Results Pathogenicity bioassays,...
The meadow spittlebug, Philaenus spumarius L. (Hemiptera: Auchenorrhyncha: Aphrophoridae), is the main vector of Xylella fastidiosa subsp. pauca strain ST53, causal agent Olive Quick Decline Syndrome. and other Auchenorrhyncha are known to communicate via vibrations, whereas possible occurrence semiochemical communication has been poorly investigated so far. Through a chemical ecology approach, we provide evidence intraspecific in P. spumarius. In Y-tube olfactometer bioassays, males were...
(1) Monitoring of Drosophila suzukii is based on the use effective traps and baits. The current baits are insufficient to provide efficient monitoring. bacteria as bio-catalyzers produce bioactive volatiles may improve flies’ attraction. Thus, we conducted this work Droskidrink® bait’s attractiveness using lactic acid bacteria. (2) Different that were assessed for attraction in a Droso-Trap® vineyard. Oenococcus oeni, Pediococcus spp., Lactobacillus spp. used. performance most attractive...
Abstract The feeding preferences of alate and apterous morphs the aphid Schizaphis graminum (Rondani) (Homoptera: Aphididae) were evaluated using leaves treated with powdered rice cultures four fungal isolates belonging to different species genus Trichoderma (Deuteromycotina: Hyphomycetes). All restrained S. from visiting leaves, but only citrinoviride Bisset also influenced preference morphs. Trials carried out supernatants obtained by centrifuging aqueous suspensions showed that aphids was...
