Wasps outclassed Treviso as they ran in nine tries to secure victory and the expected Heineken Cup bonus point
The win keeps alive Wasps' hopes of qualifying from Pool One, although the former champions will still have to beat Castres and Perpignan in January.
Tom Rees, Josh Lewsey and Tom Voyce all scored twice while Raphael Ibanez, Paul Sackey and Danny Cipriani also crossed.
Teenage centre Dominic Waldouck made an impressive European debut, setting up four of his side's tries at Adams Park.
Wasps wrapped up the try-scoring bonus point after just 30 minutes, with Waldouck heavily involved.
After Ibanez had driven over from a line-out for the first, Waldouck produced a lovely chip to supply Lewsey with his first try.
Joe Worsley powers through the Treviso defence
Rees grabbed the third under the posts before Waldouck again set up Lewsey - but the England full-back then limped off with a calf injury, to be replaced by 19-year-old Danny Cipriani.
It made no difference to Wasps' serene progress though as Cipriani and Waldouck linked up to put Voyce over in the corner and a 31-0 half-time advantage.
After the break, two superb individual scores kept the scoreboard ticking over with Sackey racing in from 70m and Rees from 50m.
Voyce claimed his second after good work from Cipriani and the fly-half grabbed his side's last try 10 minutes from time.
Wasps director of rugby Ian McGeechan:
"I'm delighted we did the simple things well and scored 55 points.
"We could have got very loose but we hung on to the ball well and still played with width.
"We were unselfish and didn't try to force it. We knew we'd have to be very professional because their pack has played some pretty good rugby."
Wasps centre Dominic Waldouck on his European debut:
"I enjoyed it a lot considering it was my debut in the Heineken Cup and our forwards gave me a really good platform to work off.
"Treviso kept coming at us but we knew they weren't one of the strongest sides in the competition. We kept to our patterns and when you do that you know you can kill sides off.
"It's nice to hear people have kind words for you but the whole team did well and that helped me.
"Having Josh Lewsey and Alex King either side of me was a great help and you learn a lot and pick up a lot of tips from being around them."
