Target‐site mutations and phenotypic failure in Myzus persicae against pyrethroids and carbamates in central Europe

open access: yesPest Management Science, EarlyView.
Molecular screening of 140 field‐collected Myzus persicae aphids revealed target‐site mutations L1014F, M918L, M918T, and L932F in the sodium channel and S431F in Ace2. The M918L mutation was the primary driver of high pyrethroid (cypermethrin) resistance, while S431F served as a definitive marker for carbamate (pirimicarb) resistance.

Validation of a novel bioassay method for the evaluation of the activity of slow‐acting insecticides on tomato borer Phthorimaea absoluta

open access: yesPest Management Science, EarlyView.
Extended bioassays revealed that azadirachtin and spirotetramat show strong delayed effects against Phthorimaea absoluta, underestimated by the standard Insecticide Resistance Action Committee (IRAC) method 022 protocol. Incorporating long‐term exposures is essential to accurately assess slow‐acting insecticides and improve resistance management ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Acute Toxicity (LC50) Of Cyhalofop Butyl on Gambusia Holbrooki

open access: yesIğdır Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020
Cyhalofob butyl is a synthetic herbist. This herbicide is a systemic herbicide and is used in weed control especially on celtic agriculture. In this study, the acute toxicity (LC50) of this herbist (Chillinger 200 EC 200, cyhalofob butyl) was investigated, which is currently used intensely in the fight against herbists in Thrace region, including ...

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.
