Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Using deep learning to assess the toxicological effects of sublethal exposure of a novel green pesticide in a stored‐product beetle

open access: yesPest Management Science, EarlyView.
This study employs an AI‐driven multidisciplinary approach to increase our understanding of the toxicological effects of sublethal concentrations of carlina oxide on Prostephanus truncatus. Sublethal exposure to the carlina oxide induced changes in motor patterns and thigmotaxis, highlighting its potential role in integrated pest management strategies.

Pathogenicity of indigenous entomopathogenic nematodes from Benin against mango fruit fly (Bactrocera dorsalis) under laboratory conditions [PDF]

open access: yes, 2018
Bactrocera dorsalis fruit fly is the economically most significant tephritid pest species on Mango, Mangifera indica L., in Benin, and entomopathogenic nematodes (EPNs) represent good candidates for its control in the soil.

Susceptibility of Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) to novel and established insecticides in Brazil: resistance survey, baseline, and implications for management

open access: yesPest Management Science, EarlyView.
Baseline susceptibility of Phthorimaea absoluta to novel insecticides isocycloseram and tolfenpyrad was established in Brazil. Diagnostic doses were proposed for early resistance detection. Early tolfenpyrad tolerance and abamectin‐driven cross‐tolerance to isocycloseram via oxidases highlight cross‐resistance risks, emphasizing the need for routine ...

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.
