Neonicotinoid Insecticides

2010
The use ofneonicotinoid insecticides has grown considerably since their introduction in 1990s. They are used extensively for the control of agriculturally important crop pests and also in the control of cat and dog fleas. Imidacloprid exploited through an elaborated structural and substituent optimization of nithiazine was launched to market in 1990 ...

A nationwide study of occurrence and exposure assessment of neonicotinoid insecticides and their metabolites in drinking water of China.

Water Research, 2020
Neonicotinoid insecticides (NNIs) are the most extensively used insecticides worldwide, threatening ecosystem and human health. However, nationwide studies of NNIs and their metabolites in drinking water are limited.

Detection of resistance to pyrethroid and neonicotinoid insecticides in the greenhouse whitefly, Trialeurodes vaporariorum (Westw.) (Hemiptera: Aleyrodidae)

, 2021
In Turkey as elsewhere, control of the greenhouse whitefly, Trialeurodes vaporariorum (Westw.) (Hemiptera: Aleyrodidae), relies extensively on the use of insecticides, which can promote the development of insecticide resistance. In this study, resistance

Oxidative stress, growth inhibition, and DNA damage in earthworms induced by the combined pollution of typical neonicotinoid insecticides and heavy metals.

Science of the Total Environment, 2020
Heavy metals pollution of soil and widespread application of neonicotinoid insecticides have caused environmental problems worldwide. To evaluate ecological toxicity resulting from the combined pollution of neonicotinoids and heavy metals, typical ...

The Neonicotinoid Insecticides

2002
The neonicotinoid insecticides are a new generation of chemical agents that have recently been developed for commercial use. Their history can be traced to the late 1970s, when chemists at Shell Chemical Company investigated the heterocyclic nitromethylenes as potential insecticides (1,2).

Potential human exposures to neonicotinoid insecticides: A review

Environmental Pollution, 2018
Due to their systemic character and high efficacy to insect controls, neonicotinoid insecticides (neonics) have been widely used in global agriculture since its introduction in early 1990. Recent studies have indicated that neonics may be ubiquitous, have longer biological half-lives in the environment once applied, and therefore implicitly suggested ...

Neonicotinoids—from zero to hero in insecticide chemistry

Pest Management Science, 2008
AbstractIn recent years, neonicotinoids have been the fastest‐growing class of insecticides in modern crop protection, with widespread use against a broad spectrum of sucking and certain chewing pests. As potent agonists, they act selectively on insect nicotinic acetylcholine receptors, their molecular target site.

Trifluoroacetyl Neonicotinoid Insecticides with Enhanced Hydrophobicity and Effectiveness

Journal of Agricultural and Food Chemistry, 2010
Neonicotinoids with nitro- or cyanoimino substituents are extensively utilized as plant-mobile (systemic) insecticides controlling the piercing-sucking insect pests. This investigation considers structural features of neonicotinoids with trifluoroacetyl pharmacophores, which may confer enhanced hydrophobicity and effectiveness.

Isoxazole-containing neonicotinoids: Design, synthesis, and insecticidal evaluation

Bioorganic & Medicinal Chemistry Letters, 2018
A series of novel isoxazole-containing neonicotinoids were synthesized from nitromethylene analogues and aromatic aldehydes in the presence of l-proline/K2CO3. Bioassays indicated that several synthesized compounds showed 40-70% mortality against brown planthopper (Nilaparvata lugens) under the concentration of 4mgL-1, higher than that of imidacloprid (

WP2 Case study: Neonicotinoid insecticides

2020
This case will focus on neonicotinoid insecticides (in short: neonics), and how thePrecautionary Principle has been applied, and contested, in the regulation of these insecticides. In the context of increasing pest resistance to established Plant Protection Products, the industry argued that the invention of neonicotinoids signified a new and ...
