Principal potato insects of Iowa and their control
There are a number of insects which attack potatoes in Iowa. The principal ones are the potato leafhopper ( Empoasca fabae Harris), the potato flea beetle (E pitrix cucumeris Harris) and the Colorado potato beetle (Leptinotarsa decemlineata Say). These three species cause large economic losses yearly to potato growers unless the proper control measures are employed. Commercial growers have found that the control of the potato leafhopper alone frequently has increased the yield of potatoes by as much as 100 bushels per acre on large acreages
