Milbemycins are a complex family of macrocyclic lactones containing a highly characteristic spiroketal group produced by Streptomyces hydroscopicus subsp. aureolarcrimosus. Milbemycin D is a minor member of a group of analogues containing a 25-isopropyl substituent. Milbemycin D is a highly selective and potent nematocide and insecticide. Like the closely related avermectin, milbemycins are thought to act on chloride-gated ion channels.
