Ulster made a perfect start to their Heineken Cup campaign with a bonus-point victory against the Italians at Ravenhill on Friday night.
HEINEKEN CUP, Pool 4
Ulster (10) 27
Tries: Wilson, N Best, McMillan, Maggs
Cons: Humphreys 2
Benetton Treviso (0) 0
A converted Roger Wilson try helped Ulster to a 10-0 lead at half-time, but Justin Fitzpatrick and Roger Wilson were sin-binned before the break.
Back-row forward Neil Best drove over for the second try on 54 minutes.
Ulster sealed the bonus point with two touchdowns in the last five minutes from Neil McMillan and Kevin Maggs.
David Humphreys missed an early penalty but the Ulster fly-half was successful with his second attempt on seven minutes.
Ulster were dominating the game and finally made it count on 21 minutes when Wilson drove over after good work from Isaac Boss and Andrew Trimble.
Scrum-half Boss, making his first start for Ulster, was forced off with a calf injury after 25 minutes and was replaced by Reece Spee.
Indiscipline hampered Ulster's efforts to extend their lead, with Fitzpatrick sin-binned on the half-hour for an off-the-ball shoulder charge on Dion Kingi.
Wilson was controversially yellow-carded by referee Jean-Pierre Mattheu in injury-time for holding on in the tackle.
And seconds later Treviso's Fabio Ongaro received the same punishment for an infringement.
Ulster continued to control the game after the break, Matt McCullough going over on 53 minutes only for the score to be ruled out for a double movement.
The second try came just a minute later when a forward drive resulted in Best going over, although Humphreys missed the conversion.
Ulster lost their rhythm midway through the half but found it again in the last five minutes as they added two more tries to clinch the bonus point.
McMillan went over in the corner from a short line-out for a converted try before a Trimble interception allowed Maggs to run in for a try, with Humphreys missing out on the extra two points.
Boss is rated doubtful for next Saturday's away game against pool favourites Biarritz although fellow scrum-half Kieran Campbell will be fit for the match after a calf injury.
However, Ulster hooker Paul Shields is out for six weeks beacuse of knee ligament damage.
Ulster coach Mark McCall:
"I thought we were always going to win the match and they posed us no real threat, but it was a frustrating night for a number of reasons.
"Our performance was a notch down from the last couple of weeks, but that happens.
"Having not played as well we still won 27-0 and scored four tries, though it should have been more."
