The association between prenatal pyrethroids exposure and children's health – current research

open access: yesInternational Journal of Occupational Medicine and Environmental Health
Exposure to pyrethroids, a widely used agricultural, forestry, and household insecticide, is a major public health concern due to its potential health effects on children.

Pesticide prioritization based on risk and model diet proposals for assessing cumulative exposure to pesticide residues in the Brazilian population through food consumption

open access: yesPest Management Science, EarlyView.
A risk classification of registered pesticides in Brazil was conducted, and the contribution of food to cumulative pesticide exposure was evaluated. Model diets were proposed, based on Brazilian consumption patterns. Abstract BACKGROUND Pesticide residue exposure assessments can be carried out during both the pre‐regulation and post‐regulation phases ...

Current resistance status of Aedes aegypti and Aedes albopictus populations in Penang Island, Malaysia

open access: yesAsian Pacific Journal of Tropical Medicine
Objective: To determine the current insecticide resistance status of Aedes (Ae.) aegypti and Ae. albopictus to four insecticides, namely 0.05% deltamethrin, 0.75% permethrin, 5% malathion and 0.25% pirimiphos–methyl using the World Health Organisation ...

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Challenges facing the management of pesticide resistance in weeds, diseases and insect pests in European agriculture and the future of effective IPM implementation

open access: yesPest Management Science, EarlyView.
Opinion on pesticide resistance and management in the European Union (EU) and United Kingdom (UK) is presented cognisant of changes in regulation that impact on mode of action availability and cropping system choice. Abstract In recent times, pesticide resistance has been managed reasonably effectively, either proactively or reactively, by monitoring ...

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

open access: yesPest 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 ...

IRRITABILITY LEVEL OF ANOPHELES STEPHENSI(DIPTERA: C’ULICIDAE) TO PYRETHROID MPREGNATED NETS IN LABORATORY CONDITION

open access: yesIranian Journal of Public Health, 2000
In a laboratory study, irritancy of five pyrethroids impregnated nets including lambdacyhalothrin, permethrin, deltamethrin, cyfluthrin and etofenprox were evaluated against a strain of An.stephensi originated from Bandar Abbas, Iran.

Deltamethrin ingestion with suicidal intent: A fatal outcome

open access: yesCHRISMED Journal of Health and Research, 2015
Deltamethrin intoxication is uncommon throughout the globe and more so the oral ingestion. The toxicity of pyrethroids is considered much less than the intoxication caused by other insecticides, especially organophosphates.
