Recent advances in the removal of neonicotinoid insecticides: classical approaches and nanomaterial applications

Discover Chemistry
Neonicotinoids are among the primary insecticides used globally, distinguished by their high efficiency against insects and low toxicity to mammals. They exhibit significant solubility and persistence in soils, making them ideal as systemic insecticides.

Comparative chronic toxicity of three neonicotinoids on New Zealand packaged honey bees.

PLoS ONE, 2018
BackgroundThiamethoxam, clothianidin, and imidacloprid are the most commonly used neonicotinoid insecticides on the Canadian prairies. There is widespread contamination of nectar and pollen with neonicotinoids, at concentrations which are sublethal for ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

RNAi‐based functional genomics tools for the beet leafhopper using microinjection and nanoparticle‐based topical spray

Insect Science, EarlyView.
• First demonstration of functional RNAi in the beet leafhopper, Neoaliturus tenellus, using both dsRNA microinjection and star polycation nanoparticle‐mediated topical spray delivery.•Microinjection achieved over 90% knockdown of Gus and Pum3, revealing gene‐specific fitness effects on survival and fecundity in beet leafhopper.•Nanoparticle‐mediated ...

Managing resistance is critical to future use of pyrethroids and neonicotinoids

California Agriculture, 2005
Synthetic pyrethroids and neonicotinoids are the most readily available alternatives to the organophosphate and carbamate insecticides. Pyrethroids have become widely used in California, and problems with insecticide resistance and ...

Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

Agricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

Agricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

Entomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.
