Spatially Optimal Habitat Management For Natural Pest Control Services 31
Zhang, Wei; van derr Werf, Wopke; Swinton, Scott M..
The control of crop pests by their natural enemies represents an important ecosystem service that maintains the stability of agricultural systems and has the potential to mitigate pest control costs. Recently, there has been growing interest in enhancing natural control services via habitat management that provides resources for adult natural enemies, such as food and shelter. Management of natural enemy populations has received little attention in the economic literature on pest control. Most such prior studies have explored optimal chemical-based pest management. One recent paper developed a threshold-based pesticide decision rule to account for the presence of natural enemies. However, no prior studies have investigated economically optimal spatial...
