Allan - Harlequin bugs are a real menace aren't they? I don't think there are 
any predatory or parasitic insects that attack them. Richard Mcdonald, the 
farmscaping expert, says the way to deal with this pest is to make an annual 
break in brassica crops. I was just discussing this with Ken Bezilla 
yesterday, asking about his experience using this method in Missouri. He 
said they had no brassica crops for a period in the summer (not sure how 
long) and it did reduce the population for the remainder of that year. 
Unfortunately the Harlequin bugs moved to the horseradish (ah, it is a 
brassica) and some flowers (Cleome?) and did not disappear off the face of 
the earth. One way to avoid having brassicas exposed is to use rowcover for 
a while. There's no easy organic answer.
