Abstract

The amount of sweet-fern was significantly related to the degree of Saratoga spittlebug adult injury to red pine on study plots in Lower Michigan. Other host plants supporting spittlebugs must be extremely abundant before populations increase enough to cause heavy injury. A spittlebug risk-rating device is presented that specifies hazard in a red pine stand by plotting per cent sweet-fern against per cent other suitable hosts.
