Abstract
Neodiprion sawflies are economic pests in pine plantations in eastern and southern United States and eastern Canada. While not a serious problem in California at the present time, they will probably become so with the advent of more intensive forest management. Little is known of the species present in California. The only specific study was that concerned with the Neodiprion abietis complex on white fir in 1952 (Struble, 1957). Miscellaneous data are available from the survey records of the Pacific Southwest Forest and Range Experiment Station, Berkeley.
