Predicting Shifts in the Range of Invasive Insect Species in the Face of Climate Change

Entomology Today

pea leafminer The pea leafminer (Liriomyza huidobrensis) is a pest of plants including peas, beans, potatoes, and spinach, and has spread from South America to Central America, Europe, Africa, and Asia. A new study on the species examines how temperature, host-plant range, and competition affect the pea leafminer’s range and how those factors can aid in predicting its invasive risk in other areas.

As average temperatures rise globally, the ranges of many species will be affected. Climate-induced shifts in the ranges of invasive species will be particularly important because of the high economic and ecological impacts of these species. And predicting the extent to which temperature increases could affect the range of invasive species could offer practical benefits, such as allowing for more…
