I know nothing about blackfly attractants but I expect that you are aware that carbon tetrachloride is an excellent attractant for some species of diptera - notably the seaweed fly, Coelopa frigida .
All the best,
Mike

During a study on attractants for sheep blowflies in New Zealand, I made a
serendipidous discovery that one of the sulphur compounds also attracted
sandflies (kiwi for blackflies). A 10 litre bottle to which 0.1ul of
compound had been added was left outside, and later I found sandflies had
flown into the bottle. Unfortunately I can't remember whether the compound
was dimethyl sulphide or ethane thiol, and the government research company
I worked for refuses to let me look at my own data, but it may be worth
following up this finding. Since I am no longer in NZ ad now have othr
research interests, I will not be following it up myself.
I would be interested if anyone has had any similar findings.
