A biocontrol program deploying a leaf-feeding beetle and a stem-boring weevil in eastern Africa against the invasive weed Parthenium hysterophorus is proving successful and is set to become a key component of integrated pest management programs to control the weed.
In the response to the fall armyworm's arrival in Africa and Asia, researchers have now identified parasitoid wasp species serving as natural enemies of the crop pest on both continents.
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 major fruit export from Vietnam, longan has been well studied in Southeast Asia, but a new profile in the open-access Journal of Integrated Pest Management offers a compilation of longan IPM research for potentially new audiences.
