how can you manage pests through plant diversification?

Synthetic pesticides might be a cheap and easy fix to pest problems, but they come with heavy baggage. Luckily, synthetic pesticides are far from the only method of managing pests - here a team of researchers lays out a seemingly simply solution to pest management: plant diversification. They explore this through various California vineyards (traditionally monocultures). Plant diversity can attract natural enemies of pests (such as parasitic wasps)  as well as beneficial insects. Not all diversity is equal, however, and its important for farmers to consider what specific ecosystem services they want the biodiversity to encourage (here, pest management) and plan their plant selection and integration carefully.
