The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Fipronil-induced enantioselective developmental toxicity to zebrafish embryo-larvae involves changes in DNA methylation

Scientific Reports, 2017
Enantioselectivity in the aquatic toxicity of chiral pesticides has been widely investigated, while the molecular mechanisms remain unclear. Thus far, few studies has focused on genomic expression related to selective toxicity in chiral pesticide, nor on

Transcriptome analysis reveals the role of the PCP pathway in fipronil and endotoxin-induced lung damage

Respiratory Research, 2019
Background Pesticide residues in food and environment along with airborne contaminants like endotoxins pose a tangible threat to living beings. Fipronil, a broad-spectrum insecticide at acute doses in combination with endotoxin has been linked to airway ...

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Route‐Dependent Toxicity and Ecological Selectivity of Melaleuca alternifolia Essential Oil in Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT The intensification of agricultural practices has led to an increase in the use of insecticides, raising concerns about the exposure of non‐target organisms, particularly pollinators. In this context, plant‐derived essential oils have been proposed as environmentally friendlier alternatives due to their low persistence; however, their ...

Efficacy of insecticides and fungicides for treatment of soybean seeds against adults of Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) [PDF]

Brazilian Journal of Biology
The soybean mealworm Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) feeds on leaves and stems in the initial stages of soybean growth, reducing grain yield and quality.

Caste‐Associated Social Context Modulates Behavioural Interactions With Insecticide‐Exposed Individuals in Nasutitermes corniger (Termitidae: Nasutitermitinae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Termites are eusocial insects that maintain cohesion and exchange information through frequent physical interactions among nestmates. This social organisation underlies the principle of horizontal insecticide transfer, which is widely exploited as a termite control strategy.

Toxicity, Repellency, and Horizontal Transfer of Foam Insecticides for Remedial Control of an Invasive Drywood Termite, Cryptotermes brevis (Blattodea: Kalotermitidae)

BioResources, 2023
Laboratory tests were conducted to compare imidacloprid and fipronil foams against various criteria to determine the effect of the deposit conditions, exposure method, and exposure time on the toxicity, repellency, and horizontal transfer of selected ...

Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.
