Performance of Photoactivated Periodate for the Degradation of the Neonicotinoid Pesticide Imidacloprid in Water

Yankuang ceshi
Neonicotinoid pesticides, including imidacloprid, acetamiprid, and thiamethoxam, are widely used in agricultural production to kill pests by disrupting signal transduction within organisms.

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Report of resistance to the neonicotinoid insecticide imidacloprid in Trialeurodes vaporariorum (Hemiptera: Aleyrodidae)

, 2007
Susceptibilities of UK and mainland European samples of Trialeurodes vaporariorum (Westwood) to the neonicotinoid insecticide imidacloprid were investigated over a 7 year period.

Effects of multigenerational imidacloprid and thiamethoxam stress on metabolism and physiology of Aphis glycines Matsumura (Hemiptera: Aphididae).

PLoS ONE, 2022
The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), a primary pest of soybean, poses a severe threat to soybean production. In this study, the 4th instar nymphs were exposed to the LC50 and LC30 of imidacloprid and thiamethoxam from F0 to

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.

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

Concentrations of Imidacloprid and Olefin-Imidacloprid Metabolite in the Walnut Husk Maggot (Diptera:Tephritidae)

Florida Entomologist, 2014
Several species of insects diminish the value of black walnut, which is considered a valuable economic and environmental tree species. Because imidacloprid has been used successfully against pests of other host plants, we investigated how it would impact larvae of the walnut husk maggot, Rhagoletis suavis (Loew), on black walnuts.

Comparative Toxicity of Bordeaux Mixture by Ingestion and Cuticular Contact Under Climate Change Conditions on Trichogramma cordubensis

Entomologia Experimentalis et Applicata, EarlyView.
In the face of environmental contamination to copper, mainly resulting from frequent copper‐based fungicide applications, it is crucial to understand the side effects of these pesticides on non‐target organisms to improve pest management. Trichogramma cordubensis, used as a biological control agent against grape berry moths in vineyards, shows strongly

Earthworms (Eisenia foetida, Savigny) mucus as complexing ligand for imidacloprid [PDF]

, 2010
Earthworms can excrete copious amounts of mucus that may affect the fraction, transport fate, and bioavailability of contaminants in soil. However, interaction of mucus with organic contaminants is still not well-known. In the present study, complexation

Movement and persistence of [14C]imidacloprid in sugar-beet plants following application to pelleted sugar-beet seed

, 1998
[C-14]Imidacloprid was applied to pelleted seeds of sugar beet which were then grown in pots of field soil. Leaves, roots and soil were analysed at intervals up to 97 days after planting and the distributions of parent compound and of several metabolites
