产品描述:
Spinosyn A is a naturally-occurring macrocyclic lactone that is a potent insecticide.{26992,26993} It acts as an agonist of insect nicotinic acetylcholinesterase receptors (nAChRs), which differ both structurally and functionally from nAChRs in vertebrates.{26995} As a result, it has low affinity for vertebrate nAChRs and has limited adverse effects in those animals.{26995,26996} Spinosyn A is produced naturally by the fermentation of the bacterium S. spinosa and its chemical synthesis has been described.{26994} Formulations containing spinosyn A have been used in the control of insects in agriculture.
