(Beyond Pesticides, October 8, 2026) Most of the focus on insecticides’ health hazards has been on neurological systems such as electrical signaling at synapses in neural networks, especially in the brain. However, a study in Toxicology, by authors at the Skeletal Muscle Lab, Institute of Integrated and Honors Studies, Kurukshetra University, India, finds that a widely used synthetic pyrethroid insecticide used for indoor and outdoor household pests damages muscles. While synthetic pyrethroids are known to attack calcium and sodium channels affecting neuronal electrical signaling, this...

DFT calculations guided the selection of allyl-β-cyclodextrin as the optimal functional monomer for fenvalerate imprinting. The resulting magnetic molecularly imprinted polymer enables selective extraction of six pyrethroids from fruits and vegetables with rapid magnetic separation and satisfactory recoveries (72%–109%). ABSTRACT A magnetic molecularly imprinted polymer (MMIP) with high specificity for pyrethroid pesticides was successfully synthesized via a surface molecular imprinting strategy. Using fenvalerate as the template, density functional theory (DFT) calculations were performed to systematically evaluate four candidate functional monomers: methacrylic acid (MAA), acrylic acid (AA), 4-vinylpyridine (4-VP), and allyl-β-cyclodextrin (allyl-β-CD). Computational analyses revealed that allyl-β-CD yields a significantly increased imprinting factor, underscoring its superior capacity to confer adsorption selectivity. Binding energy calculations further elucidated the molecular recognition mechanism underlying the MMIP–template interaction. Comprehensive physicochemical characterization, including X-ray diffraction (XRD), scanning/transmission electron microscopy (SEM/TEM), and Fourier transform infrared spectroscopy (FT-IR), confirmed both the structural integrity and surface morphology of the resulting polymer. To demonstrate practical utility, MMIPs were employed in magnetic dispersive solid-phase extraction (MDSPE) for the simultaneous purification and enrichment of six pyrethroid pesticides (Pyrs) from apple and cabbage matrices. By coupling MDSPE with high-performance liquid chromatography‒tandem mass spectrometry (HPLC‒MS/MS), a robust analytical protocol was developed and validated for the determination of pyrethroid residues in fruits and vegetables. Recovery experiments across multiple fortification levels yielded mean recoveries of 72%–109%, with relative standard deviations (RSDs) of 0.65%–5.04%. This validated MDSPE–HPLC–MS/MS method provides a cost-effective and time-saving reliable analytical tool for routine monitoring of pyrethroid residues in fresh produce, contributing to improved food safety surveillance and regulatory compliance, and offering practical applicability for routine food safety monitoring laboratories.

Pyrethroid insecticides on bednets have been the mainstay of malaria control since the millennium by killing mosquitoes. The target of these pyrethroids is the voltage-gated sodium channel (VGSC). Resistance mutations at the pyrethroid binding site (L995F/S) have spread widely, but functional tools to dissect vgsc itself have lagged behind the population-genetic surveillance data. Manipulation of vgsc via knockout or functional mutation would be a vital step towards understanding its contribution to insecticide resistance, as well as exploring its utility as a genetic control target. Here we generate and characterise two CRISPR-edited An. gambiae lines: an exonic knockout (vgscKO) and an intronic CRISPR-mediated cassette exchange intermediate (vgscInt) sited near SNPs linked to L995F. Both insertions are viable and fertile in heterozygosity but homozygous lethal, demonstrating that vgsc is haplosufficient and therefore the locus represents a viable target for population suppression genetic control strategies. These insertions can also be used as balancers for studying vgsc mutations without the confounding effects of wild type alleles. We investigate the insecticide resistance phenotype of vgscKO and demonstrate that knocking out one copy of vgsc produces reduced susceptibility to deltamethrin and DDT at sub-discriminating doses, with implications for vgsc-mediated mechanisms of insecticide resistance.
