Sure. Here are results from meta-analysis of the question[1].
Key takes:
"On average, GM technology adoption has reduced chemical pesticide use by 37%, increased crop yields by 22%, and increased farmer profits by 68%. Yield gains and pesticide reductions are larger for insect-resistant crops than for herbicide-tolerant crops. Yield and profit gains are higher in developing countries than in developed countries."
So pesticide use goes down, yields go up, resulting in fewer acres planted for the same yield resulting in even further pesticide use.
