DOI: 10.1002/ps.6100
Abstract: Abstract BACKGROUND Understanding the spatio‐temporal dynamics of prey and predator distributions can provide valuable insights into pest management strategies and conservation of natural enemies in agro‐ecosystems. The alfalfa weevil, Hypera postica (Gyllenhal), is an economically… read more here.

DOI: 10.1093/ee/nvac057
Abstract: Abstract It is widely recognized that both local and landscape-scale factors can be important drivers of crop pests, natural enemies, and biocontrol services. However, recent syntheses have found that landscape effects are inconsistent across study… read more here.

DOI: 10.1093/ee/nvy165
Abstract: Abstract Sugar feeding by biological control agents, such as parasitoid wasps, may enhance their ability to control crop pests, although its importance is likely to vary greatly through space and time. Here we quantified temporal… read more here.
