But Laporte said: "We know Jonny is a dangerous player but there is no special plan against him. We must concentrate on him because we know he's very dangerous but there is no anti-Wilkinson plan.
"We know we have to be careful when he has the ball and get in quickly because he can put us under pressure but there are other players we also need to watch."
Laporte also welcomed the new international rugby board directive to referees instructing them to hand out yellow cards and sin bin for 10 minutes players who do not roll away and allow the ball to be played quickly after tackles.
France will work on it with Joel Dume, the French Rugby Federation national director of referees, who is part of their backroom team as refereeing consultant.
"We have a top international referee working with us and this is a good decision," said Laporte.
