Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Авг. 2, 2024

While the pesticide formulations are widely used for pest control, combined effects of these with adjuvants on droplet behavior, spraying characteristics, and control still need to be studied. To clarify their impact efficacy, six acetamiprid were examined. A series laboratory field experiments conducted analyze physicochemical properties, toxicity against cotton aphids, deposition drift. The results indicated that 5% micro-emulsion (ME) enhanced features effectiveness in compared other formulations. nongjianfei considerably efficiency all when added. addition selected improved performance certain properties such as viscosity surface tension led higher aphid mortality rates, demonstrating during present study. In experiments, combination effect exhibited a size, coverage, density within canopy. However, ME was found most effective followed by nongjianfei. Furthermore, adjuvant reduced drift provided better Overall, specific spray drift, increased deposition. These findings highlighted significance selecting appropriate solid foundation efficient through UAVs.

Evaluating the Impact of Neonicotinoids on Aquatic Non-target Species: A comprehensive Review

Environmental Toxicology and Pharmacology, Год журнала: 2024, Номер unknown, С. 104606 - 104606

Опубликована: Дек. 1, 2024

Neonicotinoid insecticides (NNIs) are the fastest-growing class in agricultural protection. They target nicotinic acetylcholine receptors (nAChR) pests, stimulating nervous system at low doses and causing paralysis death higher concentrations. NNIs used crop protection, seed treatment, forestry, agriculture, flea control domestic cattle. Effective lower concentrations offering long-term control, favoured for their systemic activity. However, due to water solubility, mobility, moderate persistence, easily contaminate adjacent aquatic environments via runoff, leaching, or spray drift. While less toxic vertebrates, widespread use poses threats terrestrial organisms, neurotoxicity, nephrotoxicity, cytotoxicity, genotoxicity, immunotoxicity, hepatotoxicity, endocrine disruption, reproductive malformations. This review synthesizes research address knowledge gaps on environmental impact of proposes policies mitigate harmful effects non-target species.

China produces and consumes a large amount of neonicotinoids. A non-negligible exposure to neonicotinoids might occur for Chinese pregnant women, but relevant data remain limited. To investigate the by urinary biomonitoring in women from Wenzhou City, East China. We selected 432 City 2022. total eight parent four metabolites were determined single spot urine liquid chromatography coupled mass spectrometry. Basic characteristics, physical activity, pre-pregnant body index, intake drinking water food investigated questionnaire. Health risk was assessed hazard quotient (HQ) index (HI) based on human safety thresholds derived different health endpoints. Neonicotinoids their had detection frequency between 0 % 80.1 %. At least one neonicotinoid or metabolite detected 93.5 samples. Except clothianidin (51.2 %) N-desmethyl-acetamiprid (80.1 %), frequencies other ranged 43.8 The summed concentrations all < LOD 222.83 μg/g creatinine with median concentration 2.58 creatinine.

Sub-lethal effects of acetamiprid on the gills of the bleak Alburnus alburnus : histopathological and molecular alterations

The European Zoological Journal, Год журнала: 2025, Номер 92(1), С. 61 - 73

Опубликована: Янв. 8, 2025

The widespread and uncontrolled application of neonicotinoid pesticides represents a major threat to freshwater ecosystems, especially those near agricultural lands farms. Here, we determined for the first time mean lethal concentration (LC50–96 h) acetamiprid on bleak Alburnus alburnus juveniles investigated effect gills two environmentally relevant concentrations after short-term exposure (96 h). After defining LC50 value (34.546 mg/L), evaluated effects low (150 300 µg/L) through histological examination molecular evaluation Na+/K+-ATPase expression in gills. No morphological alterations were observed control group. Severe structural modifications samples exposed both tested concentrations, including hyperplasia hypertrophy chloride cells, epithelial detachment aneurysm formation, which are recognised as common early response chemical insults. Exposure highest induced more severe damage, with appearance necrotic pavement cells degeneration pillar cells. downregulation was following concentrations. Our results highlight importance expanding panel ecotoxicological tests required approve agrochemical compounds using different diagnostic tools an in-depth xenobiotic toxicity.

Binary Mixture of Neonicotinoid–Pyrethroid Insecticide: Impact on Survival, Cognitive Learning, and Memory in Apis mellifera jemenitica

Biology, Год журнала: 2025, Номер 14(2), С. 147 - 147

Опубликована: Янв. 30, 2025

The impact of agrochemicals on pollinators, especially honey bees, has drawn significant attention due to its critical implications for worldwide food stability and ecosystems. Given the potential threat insecticides bees may encounter multiple simultaneously during foraging. This study investigated toxic effect an insecticide mixture (IM) containing acetamiprid (neonicotinoid) deltamethrin (pyrethroid) survival cognitive appetitive performance Apis mellifera jemenitica, a vital native pollinator in arid regions Saudi Arabia. lethal concentration (LC50) was determined by assessing bees’ mortality rates following exposure IM through topical oral routes. Significant bee occurred at 4–48 h post treatment with both routes, showing trend increased higher concentrations compared control bees. Throughout all tested times, proved relatively more effective, resulting significantly greater IM. Food intake declined progressively rising exposure. LC50 values 24 after were 12.24 ppm 10.45 corresponding LC10, LC20, LC30 3.75 ppm, 5.63 7.54 2.45 4.04 5.78 exposure, respectively. combination index (CI) revealed synergistic (0.43) antagonistic effects (1.43) highlighting differential toxicity dynamics. impaired acquisition memory reinforcement as demonstrated behavioral assays, indicating neurotoxic effects.

Previously synthesized and tested water-dispersible photoactive polymeric microparticles have been employed as heterogenous photosensitizers to evaluate their performance in generating singlet oxygen through direct solar irradiation. This study utilizes these photocatalysts for the degradation of Acetamiprid IWWTP wastewater effluents from Agri-food industry, exploring, addition or simulated irradiation, influence pH on photooxidation process. Over a thousand emerging pollutants, including pesticides like Acetamiprid, detected aquatic environments recent years, posing challenges due limitations current treatment technologies. The developed method is particularly effective under basic slightly conditions, aligning with natural addressing limitation conventional methods, which typically require medium acidification be effective. Polymers P3 P4 exhibited high photocatalytic activity, achieving over 99% oxidation via generated by Rose Bengal supported polymer matrix, while maintaining catalytic efficiency across multiple cycles. results confirm that removal industrial irradiation feasible, though constrained availability sufficient sunlight hours.

Toxicology Reports, Год журнала: 2025, Номер 14, С. 101983 - 101983

Опубликована: Март 15, 2025

Thiamethoxam (TMX), a widely used second-generation neonicotinoid insecticide, has raised concerns due to its toxic effects on non-target species, including mammals. Its prolonged use is associated with hepatotoxicity, nephrotoxicity, and reproductive damage. This study evaluates the dose-dependent biochemical, histopathological, genetic of TMX in male albino rats, emphasizing impact liver, kidney, systems. Forty Wistar rats were assigned control three experimental groups treated at 26, 39, 78 mg/kg/day over eight weeks. Key biochemical markers such as Alanine transaminase (ALT), Aspartate (AST), urea, creatinine oxidative stress indicators (Catalase (CAT), Glutathione (GSH), Malondialdehyde (MDA), parameters (testosterone, sperm count, motility) analyzed. Histopathological examination testes was performed, alongside evaluation Deoxyribonucleic Acid (DNA) damage testicular tissue. exposure caused significant increases liver kidney function stress. Reproductive toxicity evident, reduced testosterone levels, impaired parameters, histopathological Notably, induced DNA tissue, indicated by increased levels 8-hydroxy-2'-deoxyguanosine. highlights TMX's systemic manner, key mechanisms. The findings underscore need for stricter regulatory measures further exploration protective strategies mitigate TMX-induced toxicity.
