Resins used by temptresses (6)
I believe the answer is:
sirens
'temptresses' is the definition.
('siren' can be a synonym of 'temptress')
'resins used' is the wordplay.
'used' indicates anagramming the letters.
'resins' anagrammed gives 'SIRENS'.
'by' is the link.
(Other definitions for sirens that I've seen before include "Warning devices with loud wailing noise" , "Devices that warn with a loud wailing noise" , "Alluring women" , "They lured mariners on to rocks with loud whistles?" , "Alarm whistles or temptresses of sailors" .)
