The things that organic farmers do to encourage beneficial insect populations would be planting hedgerows or buffer strips, rotating their crops to create more diverse food for those beneficial predators, using native plants, and intercropping. All of those strategies will basically create food and habitat sources. This is in addition to using fewer pesticides, because, again, you don't want to accidentally kill your beneficial insects.
