Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

Journal of Sleep Research, Volume 35, Issue 4, August 2026.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

Efficacy of Selected Commercial Bio‐Products in Disrupting Symbiont Acquisition and Survival of Halyomorpha halys (Hemiptera: Pentatomidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 764-773, July 2026.
Targeting the symbiont Candidatus Pantoea carbekii offers a novel way to manage the invasive brown marmorated stink bug (Halyomorpha halys). Among the three commercial bio‐products tested, Dentamet significantly reduced symbiont acquisition and caused up to 75% nymphal mortality in laboratory conditions, which was confirmed by quantitative Real‐Time ...
