Extract

A generation of wingless females of Adelges cooleyi (Gill.) is widespread on the needles of planted spruce in the Prairie Provinces of Canada and occurs on native spruces in the boreal region and in the Rocky Mountains. In order to distinguish this generation from the polymorphic cycle, it is referred to here as a ‘monomorphic cycle’.
