Ototoxicity of cypermethrin in Wistar rats

Brazilian Journal of Otorhinolaryngology, 2020
This study presents the effect of cypermethrin on the cochlear function in Wistar rats post-subchronic inhalation exposure. Worldwide several pesticides are described as causing health disorders. Cypermethrin is currently one of the most commonly used, however, little is known about its harmful effects, especially related to hearing. Human studies have

Effects of cypermethrin on Allium cepa

Environmental Toxicology, 2011
AbstractIn this study, toxic effects of the cypermethrin in Allium cepa L. cells were investigated. For this aim, we investigated the changes in pigment contents, antioxidant enzymes, mitotic index and chromosomal abnormalities as indicators of toxicity. The seeds were treated with different doses (1.5, 3.0, 6.0 ppm) of cypermethrin for 72 h.

Commercial permethrin elicits chemoreceptive responses on different Anopheles gambiae sensory appendages

Pest Management Science, EarlyView.
Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.

Synergistic transition from type‐I‐like to type‐II‐like symptomology in a pyrethroid mixture and its impact on knockdown–mortality relationships in Musca domestica L

Pest Management Science, EarlyView.
In the present study, relationship between knockdown and mortality of insecticides was examined against the adult female housefly, Musca domestica. Type‐I pyrethroid insecticides showed a weak linkage, as early knocked down flies did not always result in mortality, while type‐II pyrethroids and organophosphates exhibited strong correlation between the ...

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

Environmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Nephrotoxicity of cypermethrin in rats. Histopathological aspects.

Histology and histopathology, 2020
Cypermethrin (CYP) is an important type II pyrethroid pesticide widely used to protect crops against pests and insect infestations. However, its toxicity is a risk to both human health and the surrounding environment. The present study was conducted to investigate the nephrotoxic effect and histopathological changes caused by Cypermethrin in the kidney

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
