Synthetic pesticides are extensively and injudiciously applied to control agriculture household pests worldwide. Due their high use, toxic residues have enormously increased in the agroecosystem past several years. They caused many severe threats non-target organisms, including humans. Therefore, complete removal of compounds is gaining wide attention protect ecosystem diversity living organisms. Several methods, such as physical, chemical biological, degrade compounds, but compared other biological methods considered more efficient, fast, eco-friendly less expensive. In particular, employing microbial species purified enzymes makes degradation pollutants accessible converts them into non-toxic products by metabolic pathways.

Applications of the hormesis concept in soil and environmental health research

Soil & Environmental Health, Journal Year: 2023, Volume and Issue: 1(1), P. 100003 - 100003

Hormesis refers to positive biological effects caused by exposure low doses of a stressor known be toxic at higher doses. These include an enhanced defense system and stimulated plant/microorganism growth reproduction. has emerged as fundamental concept with broad relevance the field soil environmental health. Its utilization in evaluating ecotoxicity can reduce uncertainties introduced extrapolating from high pollutants. Similarly, its consideration risk assessment help tackle toxicity risks imposed chemical mixtures. Further, it maximize effectiveness novel agrochemicals applied lowest possible concentration, thus reducing their ecological human risks. Hormesis-based interventions, such plant priming stimulation beneficial insects waste-degrading microbes, further agrochemical loads into environment, thereby enhancing Inclusion hormesis strategies control harmful organisms, pests, pathogenic microbes algal bloom aid combating resistance.

The novel insecticides flupyradifurone and sulfoxaflor do not act synergistically with viral pathogens in reducing honey bee (Apis mellifera) survival but sulfoxaflor modulates host immunocompetence

Microbial Biotechnology, Journal Year: 2020, Volume and Issue: 14(1), P. 227 - 240

Published: Sept. 28, 2020

Summary The decline of insect pollinators threatens global food security. A major potential cause is considered to be the interaction between environmental stressors, particularly exposure pesticides and pathogens. To explore pesticide–pathogen interactions in an important pollinator insect, honey bee, we used two new nicotinic acetylcholine receptor agonist insecticides (nACHRs), flupyradifurone (FPF) sulfoxaflor (SULF), at sublethal field‐realistic doses a fully crossed experimental design with three common viral bee pathogens, Black queen cell virus (BQCV) Deformed wing (DWV) genotypes B. Through laboratory experiments which treatments were administered singly or combination individual insects, recorded harmful effects FPF pathogens on survival immune gene expression. Though found no evidence synergistic among stressors either load, combined treatment SULF DWV‐B led upregulation dicer‐like We conclude that pose threat bees, while co‐exposure these novel nACHR does not significantly exacerbate impacts host laboratory.

Exposure to low doses of pesticides induces an immune response and the production of nitric oxide in honeybees

Abstract Honeybees are essential pollinators of many agricultural crops and wild plants. However, the number managed bee colonies has declined in some regions world over last few decades, probably caused by a combination factors including parasites, pathogens pesticides. Exposure to these diverse biotic abiotic stressors is likely trigger immune responses stress pathways that affect health individual honeybees hence their contribution colony survival. We therefore investigated effects an orally administered bacterial pathogen ( Pseudomonas entomophila ) low-dose xenobiotic pesticides on honeybee survival intestinal responses. observed stressor-dependent mean lifespan, along with induction genes encoding antimicrobial peptide abaecin detoxification factor cytochrome P450 monooxygenase CYP9E2. The also triggered immediate nitric oxide synthase gene followed delayed upregulation catalase, which was not response pathogen. appear produce as specific defense when exposed stimuli. immunity-related stress-response we tested may provide useful markers for ecotoxicological assessment colonies.

Virulence of Melissococcus plutonius and secondary invaders associated with European foulbrood disease of the honey bee

MicrobiologyOpen, Journal Year: 2018, Volume and Issue: 8(3)

Published: May 24, 2018

Abstract European foulbrood is a globally distributed brood disease affecting honey bees. It may lead to lethal infections of larvae and, in severe cases, even colony collapse. Lately, profound genetic and phenotypic diversity was documented for the causative agent Melissococcus plutonius . However, experimental work on impact diverse M. strains hosts with different background completely lacking role secondary invaders poorly understood. Here, we address these issues elucidate interaction both host pathogen one another. Moreover, try unravel bacterial invasions foulbrood‐diseased larvae. We employed vitro bee from queens three strains. Larvae infection experiments showed host‐dependent survival dynamics although strain 49.3 consistently had highest virulence. This pattern also reflected significantly reduced weights strain‐infected compared other treatments. No difference found groups additionally inoculated invader ( Enterococcus faecalis or Paenibacillus alvei ) neither terms larval nor weight. These results suggest that contributes markedly course but virulence mainly dependent genotype. Secondary following do not increase lethality therefore just be colonization weakened immunodeficient, dead

Published: March 12, 2019

Climate change threatens coastal benthic communities on a global scale. However, the potential effects of ongoing warming mesophotic temperate reefs at community level remain poorly understood. Investigating how different members these will respond to future expected environmental conditions is, therefore, key anticipating their trajectories and developing specific management conservation strategies. Here, we examined responses some main components highly diverse Mediterranean coralligenous assemblages thermal stress. We performed thermotolerance experiments with temperature treatments (from 26 29°C) 10 species from phyla (three anthozoans, six sponges one ascidian) structural roles. Overall, observed species-specific contrasting regardless or growth form. Moreover, ranged resistant sensitive were mostly in agreement previous field observations mass mortality events (MMEs) linked marine heat waves. Our results unravel diversity outcrops suggest presence winners losers face climate change. Finally, this study highlights importance accounting for vulnerabilities response when forecasting ocean.
