Delta usually means a deletion so is the delta-endotoxin you are using a
cut down portion of the main toxin. Alternatively someone already found
an alpha, beta and gamma endotoxin and yours was the fourth one!

I'll ask a friend who has worked for many many years with commercial
production of BT endotoxins.
