Threatening the global community is a wide variety of potential threats, most notably invasive pest species. Invasive species are non-native organisms that humans have either accidentally or intentionally spread to new regions. One effective and first lines control strategies for controlling pests application insecticides. These toxic chemicals employed get rid pests, but they pose great risks people, animals, plants. Pesticides heavily used in managing current era. Due overuse synthetic chemicals, numerous already developed resistance. The resistance development main reason failure manage Developing pesticide management techniques necessitates thorough understanding mechanisms through which insects acquire insecticide Insects use behavioral, biochemical, physiological, genetic, metabolic methods deal with can lead continuous overexpression detoxifying enzymes. An overabundance enzymes causes resistance, pesticides rendering them ineffective against pests. A key factor amplification certain enzymes, specifically esterases, Glutathione S-transferase, Cytochromes p450 monooxygenase, hydrolyses. Additionally, insect guts offer unique habitats microbial colonization, gut bacteria may serve their hosts useful services. Most importantly, detoxification insecticides leads development. complete knowledge could be very helpful coping challenges effectively developing Integrated Pest Management particularly at lowering risk chemical environmental contaminants resulting health issues, it also ways

Role of Insect Gut Microbiota in Pesticide Degradation: A Review

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: May 3, 2022

Insect pests cause significant agricultural and economic losses to crops worldwide due their destructive activities. Pesticides are designed be poisonous intentionally released into the environment combat menace caused by these noxious pests. To survive, insects can resist toxic substances introduced humans in form of pesticides. According recent findings, microbes that live insect as symbionts have recently been found protect hosts against toxins. Symbioses formed between various microbes, a defensive mechanism pathogens Insects’ guts provide unique conditions for microbial colonization, resident bacteria deliver numerous benefits hosts. Insects vary significantly reliance on gut basic functions. digestive tracts very different shape chemical properties, which big impact structure composition community. microbiota has contribute feeding, parasite pathogen protection, immune response modulation, pesticide breakdown. The current review will examine roles detoxification mechanisms behind development resistance better understand detoxifying agriculturally pest insects, we provided comprehensive information regarding role

The function of microbial enzymes in breaking down soil contaminated with pesticides: a review

Bioprocess and Biosystems Engineering, Journal Year: 2024, Volume and Issue: 47(5), P. 597 - 620

Published: March 8, 2024

Abstract The use of pesticides and the subsequent accumulation residues in soil has become a worldwide problem. Organochlorine (OC) have spread widely environment caused contamination from past agricultural activities. This article reviews bioremediation pesticide compounds using microbial enzymes, including enzymatic degradation pathway recent development enzyme-mediated bioremediation. Enzyme-mediated is divided into phase I II, where former increases solubility through oxidation–reduction hydrolysis reactions, while latter transforms toxic pollutants less or nontoxic products conjugation reactions. identified enzymes that can degrade OC insecticides include dehalogenases, phenol hydroxylase, laccases. Recent developments to improve immobilization, encapsulation, protein engineering, which ensure its stability, recyclability, handling storage, better control reaction.

Transcriptome reveals the roles and potential mechanisms of lncRNAs in the regulation of albendazole resistance in Haemonchus contortus

BMC Genomics, Journal Year: 2024, Volume and Issue: 25(1)

Published: Feb. 17, 2024

Haemonchus contortus (H. contortus) is the most common parasitic nematode in ruminants and prevalent worldwide. H. resistance to albendazole (ABZ) hinders efficacy of anthelmintic drugs, but little known about molecular mechanisms that regulate this drug resistance. Recent research has demonstrated long noncoding RNAs (lncRNAs) can exert significant influence as pivotal regulators emergence

Transcriptome analysis reveals differential effects of beta-cypermethrin and fipronil insecticides on detoxification mechanisms in Solenopsis invicta

Frontiers in Physiology, Journal Year: 2022, Volume and Issue: 13

Published: Oct. 6, 2022

Insecticide resistance poses many challenges in insect pest control, particularly the control of destructive pests such as red imported fire ants (Solenopsis invicta). In recent years, beta-cypermethrin and fipronil have been extensively used to manage invasive ants, but their effects on development S. invicta are still unknown. To investigate development, was collected from populations five different cities Guangdong, China. The results showed 105.71- 2.98-fold higher against beta-cypermethrin, respectively, Guangzhou population. enzymatic activities acetylcholinesterase, carboxylases, glutathione S-transferases significantly increased with increasing concentrations. Transcriptomic analysis revealed 117 differentially expressed genes (DEGs) BC-ck vs. BC-30 treatments (39 upregulated 78 downregulated), 109 DEGs F-ck F-30 (33 76 499 (312 187 downregulated). Kyoto Encyclopedia Genes Genomes (KEGG) that associated insecticide were enriched metabolic pathways, AMPK signaling pathway, insulin carbon metabolism, peroxisomes, fatty acid drug metabolism enzymes xenobiotics by cytochrome P450. Furthermore, we found important for detoxification pathways regulated under both invicta. Comprehensive transcriptomic data confirmed play a significant role Guangdong Province. Numerous identified insecticide-related genes, GO terms, KEGG indicated workers insecticides. Importantly, this transcriptome profile variability serves starting point future research risk evaluation molecular mechanism ants.

The red imported fire ant, Solenopsis invicta Buren, is a significant urban, agricultural, and medical pest with wide distribution in the world. Surface or mound treatment using contact insecticide one of main methods to control S. invicta. In present study, cycloxaprid, newly discovered neonicotinoid insecticide, was evaluated for compared two referent insecticides, imidacloprid bifenthrin.Surfaces sand treated imidacloprid, bifenthrin caused high mortality workers, action cycloxaprid slower than bifenthrin. Like bifenthrin, can be horizontally transferred from corpses live donor ants recipient ants. addition, cycloxaprid- imidacloprid-treated surfaces significantly induced activities acetylcholinesterase (AChE) detoxification enzymes; nevertheless, they had no effect on foraging behaviors workers. Also, did not negatively affect digging Interestingly, workers excavated more containing 0.01 mg/kg untreated no-choice bioassays. extensive nesting (sand excavation stacking) were observed flowerpots imidacloprid. On contrary, reduced foraging, digging, workers.Cycloxaprid slow-acting nonrepellent against its horizontal toxicities are slightly higher © 2022 Society Chemical Industry.

Pest Management Science, Journal Year: 2023, Volume and Issue: 79(9), P. 3122 - 3132

Published: April 4, 2023

Abstract BACKGROUND Indoxacarb, representing an efficient insecticide, is normally made into a bait to spread the poison among red fire ants so that it can be widely applied in prevention and control of Solenopsis invicta . However, potential toxicity mechanism S. response indoxacarb remains explored. In this study, we integrated mass spectrometry imaging (MSI) untargeted metabolomics methods reveal disturbed metabolic expression levels spatial distribution within whole‐body tissue treated with indoxacarb. RESULTS Metabolomics results showed significantly altered level metabolites after treatment, such as carbohydrates, amino acids pyrimidine derivatives. Additionally, regulation several crucial resulting from pathway lipids visualized using label‐free MSI methods. Specifically, xylitol, aspartate, uracil were distributed throughout whole body , while sucrose‐6′‐phosphate glycerol mainly abdomen thymine was head chest Taken together, indicated closely associated disturbance key pathways, metabolism, aspartate pentose glucuronate interconversions, inhibited energy synthesis. CONCLUSION Collectively, these findings provide new perspective for understanding assessment between targeted organisms pesticides. © 2023 Society Chemical Industry.
