Inter returns to form with Serie A win
Inter had lost two of its past three league games, drawing the other one, but goals from Rodrigo Palacio and Fredy Guarin helped the Nerazzurri pick up all three points.
Pescara had won three of its past four games but posed little threat to the home side.
Inter dominated despite being without suspended duo Andrea Ranocchia and Juan Jesus, and Walter Samuel, Dejan Stankovic, Luca Castellazzi, Ricky Alvarez and Yuto Nagatomo, who were all missing through injury.
The 18-year-old Marco Benassi had an impressive Serie A debut after two appearances in the Europa League. Inter moves provisionally into third place.
Palacio gave Inter the lead on the half hour as he controlled Cristian Chivu's pass and turned on the edge of the area to round Christian Terlizzi before firing into the bottom right corner.
Pescara struggled to create any opportunities and Inter doubled its lead nine minutes into the second half when Palacio forced his way into the area before unselfishly cutting back for Guarin to tap home from close range.
In Bologna, Chievo had won four of its past five league games but found itself behind in the 12th minute when Panagiotis Kone lost his marker and ran into space by the penalty spot to head home Alessandro Diamanti's corner.
Chievo upped the pressure and could have leveled four minutes from halftime as first Federico Agliardi made a great save to tip Cyril Thereau's free kick around the post, before it had a penalty appeal turned down when Bostjan Cesar appeared to have his shirt tugged by Nicolo Cherubin.
However, Bologna doubled its lead moments later. Diego Perez stole the ball off Thereau on the halfway line and threaded a wonderful pass through for Gilardino, who chipped it over Chievo goalkeeper Stefano Sorrentino.
Chievo had kept clean sheets in four of its last six Serie A games but fell further behind in the second half when Cesar failed to clear a corner and, in a goalmouth scramble, Gilardino bundled the ball home.
Alberto Paloschi could have got one back for Chievo late on but he had a goal ruled out for offside before striking the post.
Manolo Gabbiadini, who also hit the post, scored Bologna's fourth a minute from fulltime.
Bologna is provisionally five points above the relegation zone.
