Early‐season plant cover supports more effective pest control than insecticide applications

Ecological Applications, Journal Year: 2022, Volume and Issue: 32(5)

Published: March 28, 2022

Growing evidence suggests that conservation agricultural practices, like no-till and cover crops, help protect annual crops from insect pests by supporting populations of resident arthropod predators. While adoption practices is growing, most field crop producers are also using more insecticides, including neonicotinoid seed coatings, as insurance against early-season pests. This tactic may disrupt benefits associated with reducing arthropods contribute to biological control. We investigated the interaction between preventive pest management (PPM) practice cropping. an alternative approach, integrated (IPM), which responds risk, rather than insecticides prophylactically. In a 3-year corn (Zea mays L.)-soy (Glycine max L.) rotation, we measured response invertebrate predators PPM IPM without crop. Using any insecticide provided some small reduction plant damage in soy, but no yield benefit. corn, vegetative early season was key density damage, likely increasing abundance Further, year 1 decreased predation compared no-pest-management Contrary our expectation, strategy, required just one application, disruptive predator community PPM, because applied pyrethroid acutely toxic wider range neonicotinoids. Promoting effective at either intervention-based strategy. Our results suggest best outcomes occur when control encouraged planting avoiding broad-spectrum much possible. As part conservation-based approach farming, can promote natural-enemy provide populations.

Pesticides used for plant protection can indirectly affect target and non-target organisms are identified as a major cause of insect decline. Depending on species interactions, pesticides be transferred into the environment from plants to preys predators. While transfer is often studied through vertebrate aquatic exposure, arthropod predators insects may represent valuable bioindicators environmental exposure pesticides. A modified QuEChERS extraction coupled with HPLC-MS/MS analysis was address question invasive hornet Vespa velutina, specialist predator honey bees. This analytical method allows accurate quantification nanogram/gram levels 42 contaminants in sample weight that obtained single individuals.

PGPR and nutrient consortia promoted cotton growth, antioxidant enzymes, and mineral uptake by suppressing sooty mold in arid climate

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: March 20, 2025

Introduction Cotton ( Gossypium hirsutum L.) plays a vital role in Pakistan’s economy, providing significant employment opportunities and supporting the country’s textile industry. However, cotton productivity is severely impacted by pests diseases, such as black spots caused sooty mold, posing critical challenges to sustainable agriculture. This study investigates novel integration of plant growth-promoting rhizobacteria (PGPR) with recommended NPK fertilizers micronutrients enhance growth, yield, disease resistance, post-harvest soil properties. Methodology A consortium Bacillus megaterium (ZR19), Paenibacillus polymyxa (IA7), sp. (IA16) were evaluated under six treatments: control (T1), PGPR (T2), (T3), + (T4), (T5), (T6). Results The results depicted increase antioxidant activities 19% superoxide dismutase (SOD), 29% peroxidase (POX), 28% (POD), 14% catalase (CAT) activity T6 compared control. Similarly, growth parameters substantially improved root length (39%), shoot (19%), biomass up 31 20%, respectively, T6. Moreover, yield attributes like single boll weight lint percentage also enhanced 32 13%, integration. In contrast, demonstrated considerable biocontrol potential against incidence was reduced 68% cotton, index 75%, efficacy reached 75%. biological chemical properties, including bacterial populations, microbial nitrogen, organic matter, essential nutrient availability. Discussion So, these findings witnessed dual behavior strains balanced nutrition can lead us development an effective biopesticide cum biofertilizer for production arid conditions combating mold effectively.

Meta-synthesis reveals interconnections among apparent drivers of insect biodiversity loss

BioScience, Journal Year: 2025, Volume and Issue: unknown

Abstract Scientific and public interest in the global status of insects has surged recently; however, understanding relative importance different stressors their interconnections remains a crucial problem. We use meta-synthetic approach to integrate recent hypotheses about insect responses into network containing 3385 edges 108 nodes. The is highly interconnected, with agricultural intensification most often identified as root cause. Habitat-related variables are connected appear be underdiscussed other stressors. also identify biases gaps literature, especially those generated from focus on economically important popular insects, pollinators, at expense non-pollinating less charismatic insects. In addition serving case study for how meta-synthesis can map conceptual landscape, our results many where future meta-analyses will offer critical insights mitigating biodiversity loss.

An Aptamer Sensor Based on Alendronic Acid-Modified Upconversion Nanoparticles Combined with Magnetic Separation for Rapid and Sensitive Detection of Thiamethoxam

Foods, Journal Year: 2025, Volume and Issue: 14(2), P. 182 - 182

Published: Jan. 9, 2025

The widespread use of thiamethoxam has led to pesticide residues that have sparked global concerns regarding ecological and human health risks. A pressing requirement exists for a detection method is both swift sensitive. Herein, we introduced an innovative fluorescence biosensor constructed from alendronic acid (ADA)-modified upconversion nanoparticles (UCNPs) linked with magnetic (MNPs) via aptamer recognition the thiamethoxam. Through base pairing, thiamethoxam-specific aptamer-functionalized MNPs (apt-MNPs) were integrated complementary DNA-functionalized UCNPs (cDNA-UCNPs) create MNPs@UCNPs biosensor. Thiamethoxam specifically attached apt-MNPs, leading their separation cDNA-UCNPs, which in turn reduction intensity at 544 nm following by external field. change (ΔI) was directly correlated concentration thiamethoxam, enabling quantitative analysis pesticide. With optimized parameters, capable quantifying within span 0.4-102.4 ng·mL-1, it achieved limit as minute 0.08 ng·mL-1. Moreover, leveraging properties MNPs, assay duration could be abbreviated 25 min. research exhibited precise sensing platform yielded promising results samples cucumber, cabbage, apple.
