A Case for Preservation: The Value and Constraints of Maintaining Insect Collections in Developing Countries
Insect collections play a critical role in recording biodiversity, recognizing and managing invasive species, addressing crop pests, and more. Developing countries could benefit the most from insect collections but often have few such resources. Experts in the field highlight the critical need for building insect collections around the world.
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.
