Habitat manipulation to mitigate the impacts of invasive arthropod pests
Exotic invaders are some of the most serious insect pests of agricultural crops around the globe. Increasingly, the structure of landscape and habitat is recognized as having a major influence on both insect pests and their natural enemies. Habitat manipulation that aims at conserving natural enemies can potentially contribute to safer and more effective control of invasive pests. In this paper, we review habitat management experiments, published during the last 10 years, which have aimed to improve biological control of invasive pests. We then discuss during what conditions habitat management to conserve natural enemies is likely to be effective and how the likelihood of success of such methods can be improved. We finally suggest an ecologically driven research agenda for habitat management programmes.We acknowledge the following funding sources: the Tertiary Education Commission, New Zealand, through the Bio-Protection Research Centre, Lincoln University, New Zealand (Mattias Jonsson and Steve Wratten), the New Zealand Foundation for Research, Science and Technology (FRST); project LINX0303 (Steve Wratten, Ross Cullen, Jean Tompkins), Lincoln University, New Zealand, for a Post-graduate Scholarship to Jean Tompkins, USDA CSREES Risk Avoidance and Mitigation Program (2004-51101-02210), USDA NC SARE Project (LCN 04-249), USDA CSREES Arthropod and Nematode Biology (2004-35302-14811), North Central Regional IPM, NSF-LTER at Kellogg Biological Station (NSF DEB 0423627), and the Michigan Agricultural Experiment Station (Doug Landis)
