Neonicotinoid insecticides play a role by affecting the synapses of insect central nervous system and preventing the transmission between nerve cells. Neonicotinoid insecticides have the characteristics of broad spectrum, high efficiency and good systemic property, and most of them can be used for foliar spraying, seed treatment or soil treatment.
Extended data:
Neonicotinoid insecticides have developed rapidly since 1990s, and they are the most important synthetic insecticides in recent 30 years. At present, they are the most effective insecticides to control sucking mouthparts pests such as whitefly, rice planthopper and aphid, and they are also important tools in the field of resistance management.
Not all neonicotinoid insecticides are highly toxic to bees, thiacloprid is low toxic to bees, and acetamiprid is far less toxic to bees than thiamethoxam, imidacloprid and thiamethoxam.
Aiming at the important target of nicotinic acetylcholine receptor, developing low-bee venom products has become an urgent new topic for multinational companies. Especially flupirone, its contact toxicity to bees is the lowest among all nicotinic acetylcholine receptor drugs; Trifluoropyrimidine is a slightly toxic product, which is the only compound that inhibits but does not activate nicotinic acetylcholine receptor.
People's Daily Online-UK supports strict control of the use of neonicotinoid insecticides.
