In the search for the perfect attactrant for the biocontrol beetle Diorhabda
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
