In the search for the perfect attactrant for the biocontrol beetle Diorhabda elongata, scientists used a technique called "electroantennographic detection." To find out which scent attracts the beetle the most, they hooked up an electrode to a beetle antenna on a severed beetle head and measured electrical stimulation triggered in the antenna by the various scents collected from other D. elongata beetles.
