In Nepal, the gall-inducing eupatorium gall fly (Procecidochares utilis) is deployed as a biological control agent against the invasive weed Ageratina adenophora. A new study by researchers at Tribhuvan University and the Feed the Future Innovation Lab for Integrated Pest Management shows size and abundance of galls induced by the fly are influenced by elevation, knowledge that can help in fine-tuning P. utilis-based biocontrol efforts.
A new report in the Journal of Integrated Pest Management shows that a beetle species released into the wild as a natural enemy of the invasive hemlock woolly adelgid appears to be successfully establishing in urban environments in addition to forest settings.
In a recent study, the wasp Spathius galinae successfully established wild populations and outperformed other parasitoids in attacking invasive emerald ash borers in three northeastern states in the U.S. Researchers say it could become a useful biological control agent to protect native ash trees.
In a new special collection on trap and cover crops in integrated pest management, experts review the latest research on various habitat-management methods and their applications in both deterring pest populations and fostering natural enemies of crop pests.
