More than a decade after its arrival in the continental U.S., spotted-wing drosophila has spread to many parts of the country. But a decade of research has built a broad knowledge base for a variety of management strategies. A new review in the Journal of Economic Entomology provides an in-depth analysis of the current state of SWD management and promising future directions.
One of the best tools for forest entomologists to manage outbreaks of the moth Lymantria dispar is a fungus, native to Japan, that was discovered in the U.S. in 1989. Entomophaga maimaiga can be spread via soil containing its spores or infected L. dispar larvae.
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.
