As the fall armyworm has expanded its range in Asia and Africa, international collaborations are at work to respond. In Nepal, early warnings and training prepared the country's agricultural community well ahead of time.
In Washington state and British Columbia, Canada, two species of wasps from Asia have been found to be successfully parasitizing the invasive fruit fly spotted-wing drosophila.
A tiny parasitoid wasp species, long considered a generalist with more than 65 different host species, is revealed in a new study to actually comprise at least 16 different species, identical in appearance but genetically distinct.
Numerous examples show the success of augmentative biological control efforts. With adequate support and capacity building in place, the approach can be economical and make agricultural systems more sustainable and improve the human and institutional capacity of developing countries.
