We study ways to enhance and restore the diversity and functioning of beneficial insects in agricultural landscapes, while minimizing the delivery of dis-services by pests. Specifically, we study the effects of wild bloom along field edges on the diversity and interactions between three important guilds - pollinators, natural enemies (insect predators and parasitoides) and insect pests. We also study successional processes in bee communities in novel habitats, and the cost-effectiveness of different restoration approaches.
