Title:

Community matters: a tree-killing bark beetle does not escape its natural enemies as its range expands

Southern pine beetle (SPB) is an outbreak insect of economic and ecological importance. The arthropod community associated with SPB, including predators, competitors, and parasitoids has been well documented and is known to impact SPB dynamics. In 2014, a major range expansion of SPB was detected (Fig. 1). We compared the insect community associated with SPB attacks in the historic versus novel range. We found the SPB-associated insect community in NY to be similar in composition, but with important differences in insect abundance and behavior, compared to that of the historic range.
