General description

Find more information here: Neonicotinoids
Thiamethoxam is a neonicotinoid broad spectrumand systemic insecticide, which belongs to the subclass of thianicotinyls. It can find applications in controlling the growth of sucking insects like aphids, whiteflies, and rice hoppers by acting on the acetylcholine nicotinic receptors.

Application

Neonicotinoid pesticides are used in agriculture to reduce damage from crop pests. However, beneficial insects such as bees can come into contact with these pesticides when foraging in treated areas, with potential consequences for bee declines and pollination service delivery.

Thiamethoxam (3-[(2-chloro-5-thiazolyl)methyl]tetrahydro-5-methyl-N-nitro-4H-1,3,5-oxadiazin-4-imine) belongs to a relatively new class of insecticides known as neonicotinoids, which can block irreversibly nicotinic acetylcholine receptors of the nervous system of insects. Its determination at trace levels is an acute analytical problem. Therefore, chromatography, spectroscopy, and

Neonicotinoid pesticides have been linked to global declines of beneficial insects such as bumblebees. Exposure to trace levels of these chemicals causes sub-lethal effects, such as reduced learning and foraging efficiency. Complex behaviours may be particularly vulnerable to the neurotoxic

Thiamethoxam is the first commercial neonicotinoid insecticide from the thianicotinyl subclass. It was discovered in the course of our optimisation program on neonicotinoids started in 1985. Novel variations of the nitroimino-heterocycle of imidacloprid led to 4-nitroimino-1,3,5-oxadiazinanes exhibiting high insecticidal activity.

On Friday, April 27, 2018, the European Union decided to ban the use of three neonicotinoid insecticides from use on field crops, having deemed them dangerous to bees. This application demonstrates the analysis of these banned compounds and others from dandelion blossoms using QuEChERS and LC-MS.
