Interpretive Summary: Wood-boring insects cause millions of dollars of damage each year to forests and forest products and ornamental trees and shrubs. Woodwasps of the family Siricidae bore and feed in the wood of conifers and broadleaf trees, and 15 species in five genera occur in eastern United States. Because they take several years to develop, they are often distributed by commerce and may emerge from lumber outside their native range. Two species in eastern United States are introductions from Europe and southeastern Asia, and others have been found emerging from lumber imported from the western United States. Keys for the identification of the eastern species and two of their parasites are presented, as well as their distribution and recorded hosts. Several non-native species are included because of their potential for introduction. Accurate identifiction of these species will save time and help determine control methods. It will benefit the Forest Service and others interested in wood-boring insects, help to identify species emerging in buildings, and aid action agencies such as APHIS in excluding additional invasive species.

Technical Abstract: Keys are presented for the five genera and 15 species of Siricidae and one genus and two species of Ibaliidae that occur or may be adventive in eastern United States. Distribution and host information are given. Data from collections in the mid-Atlantic states include seasonal occurrence of both the siricids and their ibaliid parasitoids.
