Neonicotinoids are a new class of insecticides with widespread use in veterinary medicine and crop production. The neonicotinoid insecticides include imidacloprid, acetamiprid, dinotefuran, thiamethoxam, and clothianidin. Neonicotinoids have a relatively low risk for nontarget organisms and the environment and high-target specificity to insects.

Neonicotinoids (sometimes shortened to neonics/ˈni:oʊnɪks/) are a class of neuroactive insecticides chemically similar to nicotine. The neonicotinoid family includes acetamiprid, clothianidin, imidacloprid, nitenpyram, nithiazine, thiacloprid, and thiamethoxam.

In insects, neonicotinoids cause paralysis which leads to death, often within a few hours.
Selectivity for insects arises from differences in the structure and composition of the nAChR in insects and mammals; these Neonicotinoids are used in producing many types of crops, including rice, cotton, corn, potatoes and soybeans.

Studies show that neonicotinoid residues accumulate in pollen and nectar of treated plants and represent a potential risk to pollinators. Government to let farmers use bee-killing pesticide banned by EU ‘We need urgent action to restore the abundance of our insect populations, not broken promises that make the ecological crisis What about Neonicotinoids?
The neonicotinoids are a class of insecticides with a common mode of pesticidal action that affects the central nervous system of insects, causing paralysis and death. All of the neonicotinoids were registered after 1984 and were not subject to reregistration.
