Leading marksman Sam Winnall fired the Iron ahead after just six minutes with his ninth goal of the season.
An own goal from Torquay centre-back Anthony O'Connor made it 2-0 on the half-hour before teenage substitute Hakeeb Adelakun wrapped up the points in the 61st minute with his first ever league goal.
A 78th-minute reply from John Marquis was too little, too late for the struggling visitors.
"I thought our two centre-halves were immense, they won everything Torquay through into our box," said Wilcox.
"As a team performance it was not one of our best, but in this business its results that matter and after three successive wins I don't want to sound negative.
"We have done swell to achieve that and there were spells in this game that we played well. I was pleased with the way we managed the game.
"After three wins, of course I am enjoying it at the moment, but I know that will not last forever. The test will come of how we respond to a defeat.
"We have got ourselves into a great position and if we continue to work hard, then there is no reason for us to fear anyone in this division. Any team in the top 12 will feel it has a real chance of getting out this season."
Wilcox was also full of praise for 17-year-old former West Ham junior Adelakun, adding: "He made his full debut at Rochdale in midweek but I left him on the bench today because I felt he was looking tired.
"I remember when I made my debut that I felt physically and mentally drained after it. But Hakeeb has come on and got a great goal for us."
