The ability of spinosyn A to either enhance or displace binding to selected insecticidally-relevant receptors was investigated using a number of radioligands including, [3H]imidacloprid and [3H]ivermectin in tissues from the ventral nerve cord (VNC) membranes of the American cockroach, Periplaneta americana and head membranes from the housefly, Musca domestica. In these insect neural tissues, spinosyn A does not appear to alter the binding of a number of radioligands suggesting that spinosyn A does not interact directly with a variety of known receptors, including nicotinic or γ-aminobutyric acid (GABA)-based insecticidal target sites. However, available data are consistent with spinosyn A interacting with a site distinct from currently known insecticidal target sites, thus supporting a novel insecticidal mechanism of action for the spinosyns.
