Flea beetles are chronically the most economically damaging insect pests of canola. Although the crucifer flea beetle remains the predominant species, this study shows the striped flea beetle to be expanding its range across Western Canada. As these two species respond very differently to their environment, spring scouting is critical to planning proper control strategies.

Crucifer flea beetle (P. cruciferae) is most frequently found in the southern Prairies while striped flea beetle (P. striolata) is traditionally found in the Parkland Region of the northern Prairies and the Peace River Region of Alberta. A third species, the hop flea beetle,
